Does Rustic Appeal To You?

I came across this building up at Snape Maltings on the Suffolk coast. The original building was almost gone, and the new owners could have taken it apart bit by bit and rebuilt it with lime mortar, and importing used bricks to make up the considerable deficiency.

…there’s a touch of Antony Gormley’s Angel of The North in letting the metal brave the elements.

They decided on a different approach, which was to weld up some steel plates (boiler plate) rather in the manner of an upside down ship. The master stroke was to leave it unprotected – so it rusted. There is a touch of Antony Gormley’s Angel of The North, in letting the metal brave the elements. It may not be the kind of thing that many people want to live in, but among the restored Maltings and cottages of that area, this building stands out and I believe in a good way. Presumably they have some very effective insulation on the inside.

Tell me what you think.

Condensing Boiler Blunder

0
Condensing boilers have undoubtedly become more reliable over the last few years..

But the last couple of winters saw thousands of householders caught out by frozen condensate. Manufacturers offer clear guidelines for avoiding freezing, but not every job offers the opportunity to do things by the book and terminate the condensation inside the building. If the pipe runs to an outside drain, then there is always a chance that it will freeze. In response to this, we now have a number of products on offer which will stop condensate pipes from freezing. Invariably these use electric trace heating (electric blanket) for the pipe. An average cost for fitting trace heating is around £200.

…installers are being advised to redouble their efforts to find somewhere inside the building to terminate the condensate.

The question is who pays? If you’ve had a condensing boiler fitted in the last few years and have suffered a breakdown due to the condensate freezing, you might reasonably expect the person who installed it to carry out the remedial action free of charge, on the grounds that the boiler was not fit for purpose. However, it seems that many installers are arguing the point saying that practice of lagging the pipe should have been enough under normal circumstances to prevent freezing, and the only reason the pipes are now freezing is abnormal weather. In other words, the boiler will work fine so long as it doesn’t get very cold. Some would say that this misses the point.

The quick fix offered by many installers and manufacturers of condensing boilers last winter, was to take a kettle of hot water and pour it over the condensation pipe. It’s a very British solution to, ‘put the kettle on’ and the site of people out in their dressing gowns at 6am with steaming kettles has a kind of pathetic charm.

In the longer term, installers are being advised to redouble their efforts to find somewhere inside the building to terminate the condensate. Ideally, this will be a soil stack or waste pipe from a kitchen sink ,but I give full marks to a heating installer I came across the other week, who found a handy soil and vent pipe close by to put his condensate into. He drilled a hole and fitted a strap on boss (sounds pornographic if you aren’t a plumber) and left the condensing boiler in good working order.

A few hours later the householder called to say that there was dripping coming through the ceiling. The installer, being a psychic, said he knew the cause without even coming back to the house. It was the WC upstairs which was leaking.

The householder found it strange that this should happen at the very time the condensing boiler was fitted and the dripping had stopped since he switched off the boiler, but the installer insisted that it was nothing to do with him and told the householder that coincidences must happen, otherwise there would be no such word as ‘coincidence’. Not only was it nothing to do with him, but he wasn’t interested in fixing the problem because he was a heating installer – not a plumber. He hadn’t spent thousands of pounds gaining his gas safety certificates just to end up messing about with bogs.

So it came down to me, a lowly jobbing plumber, no job too small. It took me less than five minutes to track down the leak. It wasn’t coming from the WC at all; it was dripping out of the ceiling fan.

The reason it was dripping out of the ceiling fan was that the installer had terminated the condensate into a length of grey plastic soil pipe, that he took to be the vent section of the soil and vent pipe. It was in fact the vent duct from the extractor fan.

Mistakes happen and I wouldn’t judge him too harshly on this one, except for the fact that he still wasn’t putting his hands up to the error. He had taken the pipe to be a soil pipe in good faith when he had put in the estimate, and the fact that it wasn’t meant that he now had to run the condensate pipe some considerable distance to pick up the said soil pipe. Suddenly he was the aggrieved party.

The householder was faced with a bill for another £200 to do the job properly, or he could poke it out of the wall and take responsibility for it freezing. But if it did freeze all he would need is a kettle full of hot water.

What Is A Condensing Boiler?

Building Site from Hell

0
I am currently working on the building site from hell..

It was a job I took on against my better judgment. When I was pricing it, alarm bells were ringing in my head because there was a new spec and drawing almost every day. The job itself isn’t actually that bad; it’s a complete re-plumb on a large central London house with an ensuite on every bedroom, and underfloor heating throughout. The money is good, but what makes it so difficult is the bloke running it. He calls himself a builder, but he has no idea.

Almost daily, my mate and me enter into protracted arguments with him about the difference between the way he says he does it in the Middle East, and the way we do it here. Invariably we walk off the job in protest at the latest demands. We only go back because the client, who is a lovely person deserving of much better than this idiot site agent, pleads for us to return. We agree, provided we can do the job the way we always do it.

“Even at this stage, there isn’t a day that goes by when the drawing doesn’t have an amendment…”

Quite what his appeal is we don’t know, but there is some kind of family link and it doesn’t do to get between family. Even at this stage there isn’t a day that goes by when the drawing doesn’t have an amendment; the boiler has been in three places, the shower room has changed, the bathroom has been turned 90 degrees and every pipe run is moved and moved again. We have three 90 degree spigot bends one after another on a horizontal soil run, because the architect had overlooked a steel beam that is in the way. It will block, we know it will. They will have to set up an account at Dyno-Rod.

It isn’t just us that are unhappy on this building site; every trade in the house has been subjected to the same kind of lunacy. Walls move, doors are altered this way and that and crazy demands are made. The vast expanse of folding patio doors had to be remade, because the floor insulation hadn’t been taken into account.

As is common on most building sites these days, there is every nationality under the sun. We all rub along very well and have a laugh and a joke united in our hatred of the common enemy, the site agent. We have been on to him for weeks to supply a porta-loo, but he gives us a bucket and we use it behind the shed. It’s a return to a time I thought was over.

His latest demand, when arriving at the building site, is that we turn on the central heating to dry out the floor screed. It was laid over our pipes only 6 days ago and he wants us to fire up the heating and dry it out so he can lay the oak flooring. I have told him it will crack and turn to powder if the moisture isn’t allowed to stay in it long enough for it to complete its hydration, which is usually 28 days give or take. I told him that until that time, the more moisture you can hold in the screed the better.

A screed is laid almost dry and it needs all the moisture to stay in and hydrate the cement, but Abdul knows best. Despite the fact that some of the tradesmen speak very little English, they all have this phrase “Abdul knows best” word perfect. For our part we are learning lots of new languages, or at least the swear words.

Fault Finding – A Plumber’s Tale

0
The golden rule that I have followed through years of fault finding is ‘never assume and never jump to conclusions’.

OK that is two fault finding golden rules, but the basic message is never say you know something until you prove it. This has stood me in good stead, where other tradesmen have come and gone from a job missing one small fact that changed everything. This is not superior wisdom, just hard won experience from getting it wrong. And sometimes I still get it wrong as this job proves.

I had been called out to look at a fault finding leak around the bath. It is almost always due to a defective silicone seal, but I didn’t just assume that. I checked it by spraying water all around the edge of the bath. Sure enough the water poured down. Positive proof! Fault finding completed!

The leak had been going for some while and made a real mess. We got the job to take the bath out, renew the rotten chipboard floor and cover the walls with Knauf Aquapanel, before re-tiling. This was the fourth flat in the block to suffer from these problems and it had caused bad feelings among the owners, so this customer didn’t want any further trouble from his bathroom. He didn’t mind paying for a good job, but he wanted a guarantee. Now I know there are some plumbers who would not put their name on a piece of paper that says ‘this won’t leak’ but I was 100% confident in both my plan and fault finding accuracy.

Firstly we were going to renew the floor, and then we were going to get rid of the plasterboard at the shower end and put up some tile backer board. We were also going to beef up the stud work to prevent any movement. Then we were going to tile the floor under the bath so the tiles came right up to the wall. The Ardex shower waterproofing system would then be used to make a damp proof membrane that ran down the walls behind the bath and onto the floor, so any leak would not be able to seep down under the floor.

There would be a silicone seal between the bath and the wall, and then another silicone seal after the wall had been tiled. It was near enough a week’s work to do this but I told the customer that I was sure after all that it wouldn’t leak, but if it ever did (which I doubted) he would know about it because the water would seep out from under the bath panel and appear as a puddle on the tiled floor. This might seem like belt and braces, but it is actually standard practice on the Continent, we are almost alone in ending the tiles just under the bath panel.

We obviously tested the bath waste, and even replaced the flexi tap connectors – just for good measure. I have heard too many horror stories about flexis springing a leak and would never use them in a flat. We finished on Friday lunchtime and everything looked good. That weekend I received a text saying that a puddle had appeared on the bathroom floor.

Fault Finding – Fault Not Found

It was Sunday morning but I went straight over. The leak appeared to be coming from the bath waste so I took it apart. There were traces of Plumber’s Mait on the underside of the waste, which indicated that this had been a previous problem which someone had tried to fix. We had obviously disturbed a bad repair. Plumber’s Mait is not suitable for bedding in wastes of any sort, but thousands of people use it for this job every year. If you ask Evo-Stik, the manufacturers, they will verify that it is unsuitable for wastes. If you need a sealant for wastes then silicone is much better.

I removed all of the Plumber’s Mait and, because the rubber seals looked fine, left them to do the job they were designed to do. I ran the bath and it looked OK. Monday morning I got another text ‘Bath still leaking, please fix today’. This time I decided to renew the whole pop up waste assembly. It looked fine.

Monday night text number three ‘still leaking, pissed off’. Looking on the positive side at least – the idea of tiling up to the wall and sealing the wall to floor joint had paid off with an early warning of what was really a small leak. If we hadn’t done this, then the people in the flat below would have been the first to know.

Fault Finding – Fault Found

I went back to the bathroom and after half an hour of having the bath full of water and nothing coming out, I wondered if the problem was more to do with the person using the bath, than the bath itself. He was a big guy and I wondered what difference it would make if you had another 110kg in the bath. It all seemed solid but would things start flexing? My next fault finding move was how to simulate this. I certainly didn’t want him sitting in the bath while I crawled about with a torch, even if he was willing. It would take a month of Sundays to get that image out of my head.

I lay there, head on the floor, deep in thought. It was at this point that the torchlight caught a single silver drop of water. It wasn’t coming from the waste; it was coming from the glass fibre of the bath. I pushed it with my finger and a few more drops came down. I discovered that the bath was spongy. I could actually push a blister of water around. Clearly it had leaked through the acrylic top and been trapped by the reinforcing coat of glass fibre. I shone the torch down through the water and there it was a hairline crack.

The one thing I hadn’t proved at the outset, was that the bath was watertight. Because 95% of leaks on baths turn out to be from around the silicone seal, I had jumped to the conclusion that it was the cause and I hadn’t looked at a secondary cause.

The task now was to remove the damaged bath (easy with a recip saw) and then fit a new bath, without damaging all those lovely new tiles or the new bath. That was slightly trickier because it was a snug fit. The customer, obviously not expecting to lose weight any time soon, decided to go for a steel bath. Good choice in his case.

When we cut that old bath in half you could see the weak spot. It was all along the edge of the chipboard reinforcing panel, where the inner acrylic joined the outer glass fibre. There was a triangular void all the way along both edges. It was inevitable that it would fail fat bloke or not, but the fact that the percentage of obese people in Britain has now reached epidemic proportions, means that plumbers will be busier with this kind of work. Something to bare in mind when fault finding in a bathroom for sure.

Carbon Monoxide Poisoning Surge

0

I have just read that the number of carbon monoxide poisoning incidents has increased over last year. The reason isn’t entirely clear, but I will offer two suggestions.

Firstly, the exceptionally cold winter. Nearly all carbon monoxide poisoning is from open-flued appliances such as gas fires. These require a through-flow of fresh air from outside. Natural ventilation which may be tolerated during a mild winter suddenly becomes an icy blast. I saw several incidents last year where people had taped up air bricks and tried to seal every available gap around the doors and windows.

the need to keep going for refresher courses and paying out extortionate fees for registering has pushed out perfectly competent fitters…

Secondly, the cost of having a Gas Safe engineer out to service the appliance has risen because many people, such as me for example, who are not specialising in gas work find the Gas Safe registration and training courses too onerous for the amount of gas work I do. At most I may install five boilers a year and service another ten. This does not justify registration so I now end up getting them done by a sub-contractor.

I am all for safety but the need to keep going for refresher courses and paying out extortionate fees for registering, has pushed out perfectly competent fitters and given those left in the game the opportunity to charge more. I don’t blame them for this because they have to cover the cost of all those courses. As with so many things, it is the poor who suffer – particularly those in fuel poverty because they either forgo the annual service, or use an unregistered service engineer who may or may not know what he/she is doing.

My proposal is that the HSE lets people who prove their competence through an exam, register for a small fee. We would then pay a notification fee to Gas Safe for each appliance we work on. This would mean that those who did a small amount of work would not have to pay a disproportionate fee.

All gas work would be subjected to random inspections by local safety inspectors, who would be paid out of that fund. Any installation that didn’t pass a safety test would be shut down and the installer sent for training, or banned according to the severity. At present, there is a voluntary scheme where a household can nominate their gas work for random inspection. This leaves the householder feeling as if they are snitching on the installer (because the installer is informed by Gas Safe) and the installer may therefore be reluctant to return for annual servicing.

If there were a duty on the householder to send off the registration card, this would protect the consumer from such accusations and make sure that all gas work is subjected to random inspection. I am sure there are reasons why this would not work and there are those out there who may think it is no better than the system we have right now, but if the number of deaths from carbon monoxide poisoning is increasing, then it is clear that something isn’t working.

Another idea I will put up for discussion is for Gas companies to offer free service and safety checks to the elderly.

Building Company Fined – Children Risked Carbon Monoxide Poisoning

MORE FROM THE NHS

The symptoms of carbon monoxide poisoning are not always obvious, particularly during low-level exposure.

A tension-type headache is the most common symptom of mild carbon monoxide poisoning.

Symptoms of carbon monoxide poisoning

  • Dizziness
  • Feeling and being sick
  • Tiredness and confusion
  • Stomach pain
  • Shortness of breath and difficulty breathing

The symptoms of exposure to low levels of carbon monoxide can be similar to those of food poisoning and flu.

But unlike flu, carbon monoxide poisoning does not cause a high temperature.

The symptoms can gradually get worse with prolonged exposure to carbon monoxide, leading to a delay in diagnosis.

Your symptoms may be less severe when you’re away from the source of the carbon monoxide.

If this is the case, you should investigate the possibility of a carbon monoxide leak and ask a suitably qualified professional to check any appliances you think may be faulty and leaking gas.

The longer you inhale the gas, the worse your symptoms will be. You may lose balance, vision and memory and, eventually, you may lose consciousness.

This can happen within 2 hours if there’s a lot of carbon monoxide in the air.

Precious Scrap Metal

0

Have you noticed any increase in the number of scrap metal men doing the rounds? I certainly have, not least because the scrap metal I had set aside recently on one of my jobs walked off after just ten minutes. Two hours later I had another visit from someone who was similarly interested, but this time he didn’t particularly care whether the copper tube was old or new. So keen was this young man on the concept of recycling, that he thought he might just cut out the middle man (me) and go from the merchant to scrap dealer without the copper ever being used for plumbing.

I stopped him in the nick of time. He was not particularly bothered by being caught like this. He had, in the process of stealing things from building sites, become desensitised to physical and verbal abuse. “It’s the Chinese” he said “They’re taking all the scrap and there’s a shortage”.

This champion of free enterprise who was scurrying down the drive with my copper, was just doing his patriotic best to help alleviate the shortage.

I was impressed by this immediate blame transference. He gets caught stealing and it is immediately the fault of some mythical figure from halfway around the world. It seems that the Chinese are now to blame for everything from global warming to material shortages. This champion of free enterprise who was scurrying down the drive with my copper, was just doing his patriotic best to help alleviate the shortage. By keeping the supply up he was also helping keep the price down – which is good for me when I have to replace it.

Scrap metal for recycling

It suddenly dawned on me that perhaps the problem is not that we don’t have enough raw materials, it is simply that these materials are not moving around the system fast enough. The 25 years (minimum) that copper spends lying around in people’s house is way too long. We need a much faster throughput.

The Scrap Metal Conundrum

If you are wondering what I did with the thief having recovered my property, the answer is nothing. I could have called the police but in my experience, they never turn up when you need them. I may also have ‘taught him a lesson’ but it wouldn’t have been not to steal, it would have been to run faster next time.

The serious point here is that scrap metal theft is now such a serious problem, that millions of pounds worth of cable is being stolen from our railway lines, manhole covers are being removed from roads and war memorials stolen. Scrap metal dealers know they are buying stolen goods, but often turn a blind eye. The Home Office is now looking to change the law to make it harder to sell scrap. They are looking at increased regulation of scrap dealers, which is a typical government response. Produce another licence. This is wishful thinking because the problem starts way down the chain from the legitimate dealers who would buy the licence.

The scrap metal business at this level is run like the drug trade, small dealers to bigger dealers and always for cash. In fact there are many drug addicts who rely on scrap metal theft for their daily fix. The only way that this business will be brought into line is if the cash is eliminated from the transaction.

If those people who earn their living roaming the streets looking for scrap could only receive payment through BACS, you would see an immediate drop in thefts. As it is at present they turn up at the scrap dealer with a false name, give a false vehicle registration and are gone. It is so easy and lucrative it is a wonder that everyone isn’t doing it.

Who Needs A Waste Carriers Licence?

Aircrete Blocks Cracking up – Unwanted Trouble

0

If you have been drawn to this blog by the title alone, I will save you wasting further time by saying from the outset that I am talking about buildings here – not a mental breakdown, though that can never be ruled out in the building game.

Certainly the owner of the house in this story needs an extraordinary degree of optimism and patience, in order to preserve his sanity, as his new house continues to crack before his eyes.

There are of course many reasons why buildings may crack, but this blog is talking about buildings made of Aircrete blocks, which a few months after completion started showing a number of large cracks.

As with so many of these problems, everyone involved is pointing a finger at someone else. Is it the blocks, the brickies, the plasterers or the architect who is to blame?

Aircrete blocks are lightweight and have a very high degree of insulation. When introduced they seemed like the wonder product of the age and to some extent, they do a job that no other materials can do.

I think it’s accurate to say that when they were first developed, the intention was to use them on internal skins of cavity walls instead of breeze blocks, which are heavier and not such good insulators.

This is still where they are mostly used. There are however a growing number of buildings being built with external skins of Aircrete blocks, and there are even buildings being built with solid Aircrete. That is to say no cavity.

The appeal of Aircrete blocks over bricks is speed and affordability. They are a good product in their own way, but the builder needs to understand their limitations.

The appeal of Aircrete blocks over bricks is speed and affordability. They are a good product in their own way, but the builder needs to understand their limitations.

 

Aircrete Blocks Golden Rule

There is a golden rule in the building industry that states:

‘mortar should never be stronger than the material it is joining’.

It’s a rule often broken. Having worked as a brickie’s labourer in my teens, I can tell you from my own experience two very good reasons that this rule is broken: One is laziness, and the other is ignorance.

Often the two go hand in hand. The general advice is that a cavity wall is brought up more or less equally on both sides, rather than building the inner skin and then the outer.

Again this isn’t always done, but if it is done then it is highly likely that the mortar being used is sometimes the same strength inside and out.

Labourers just can’t be bothered to chop and change mixes, or throw stuff away. At best they may put it back in the mixer and add a bit more cement, but even that is a hassle, so they tend to mix a fairly strong mortar for the bricks and serve it up for the blocks as well.

Another bit of advice is that Aircrete blocks should ideally be laid with a sand/cement/lime mix of around 6.1.1 or even 8.1.1 for Solar blocks.

If you look at how much lime a builders merchant sells compared to the number of Aircrete blocks he shifts, you will see that very few people follow this recipe.

It is far more likely that they will weaken the mortar with plasticisers or (in some cases) washing up liquid.

This gives them a lightweight mix with plenty of room for movement, but the problem here is that the amount of cement is not sufficient to cover all that sand.

I would argue that for this reason alone, lime is always better than plasticiser, because it mixes with the cement and spreads it further to form a more consistent mix.

The block manufacturers are painfully aware of all these problems and issue guidelines to avoid cracking.

This involves the use of movement joints, which must come all the way through the render. You only need to look around at rendered houses to see how rarely this is done.

That is the ideal scenario but, as I have said, the reality is that the labourer will often knock up a 4 or 5 to 1 mix of sand and cement with a squirt of plasticiser, which is then used throughout the build.

If the Aircrete blocks are used on the internal skin only, and that is later dry-lined with plasterboard, then the subsequent shrinkage cracks will never be seen. In any event this will probably do no harm.

If the Aircrete blocks are used on the external skins, then the cracks cannot be covered because they will almost invariably show through the render.

Even if the build mortar is the right strength to allow for movement in the blocks, this good work can be undone by applying render that is too strong.

Getting the render mix right is absolutely critical, but once again there are plenty of plasterers out there who struggle to keep a good coat of render on an Aircrete wall, and to make matters worse their answer is to use even more cement.

The real answer is to apply a slurry coat to the blocks and then when this is dry, apply the scratch coat.

The Aircrete block manufacturers are painfully aware of all these problems and issue guidelines to avoid cracking.

This involves the use of movement joints, which must come all the way through the render. You only need to look around at rendered houses to see how rarely this is done.

People just don’t like the look of them. The other measure to avoid cracking is to use bed joint reinforcement at vulnerable points. This is typically around and below windows.

The fact that there is no load directly beneath a window, means that the block work can simply pull apart in the middle.

Again, you only need to ask a builders merchant for bed joint reinforcement to see that it is rarely used. Very few stock it, and some merchants have never heard of it.

What this means is that block manufacturers can simply point to these omissions or errors and wash their hands of any problems. “If you don’t follow the guidelines, you only have yourself to blame” they will say.

I would say they could help a lot more by printing the guidelines on the packs, but I suspect they don’t really like the word ‘cracking’ to appear too close to their brand name.

There is another little point that can also help prevent cracking in rendered walls (this applies to brick as well) and that is the use of serpentine curves in the scratch coat.

It seems like such a small and insignificant thing, but it can make all the difference. If the first coat of render is lined through with horizontal lines, then the topcoat will grab it along these lines.

As that topcoat shrinks, it will pull on those horizontal lines, and hold the wall in tension as the render dries out and tries to shrink.

The problem is that all the tension is in a vertical direction, so the natural tendency is for the wall to move in the opposite direction, which is horizontal. So, as strange as it may seem, a horizontal scratch coat will produce vertical cracks.

Again I see hundreds of jobs where the scratch coat is horizontally lined, often with a notched tiling trowel.

Is it the Aircrete blocks, the Brickies, the Plasterers or the Architect who is to blame?

In fact, the whole approach of plasterers to rendering Aircrete blocks, is often completely wrong. They assume that the wavy lines which are put on the blocks at the factory, are a key for their plaster or render – which is wrong.

If you walk around many buildings using Aircrete blocks a few weeks after they have been rendered and tap the walls, you will often here a hollow sound.

Shortly after that come the cracks, and after that the solicitor’s letters, with everyone pointing the finger at someone else. The best excuse of all… the weather.

Tax Laws Power Market Inequality

0

I have just heard an item on BBC Radio 4 about the huge increase in the cost of raw materials for the building industry. The price of Bricks and concrete have reportedly soared by a potent 20%! Tax laws are an important factor fuelling inequality within this market. While average inflation, according to the retail price index, shows a 2 or 3% rise, the cost of ‘trade’ inflation could be much higher.

The trouble is that there is no barometer for this because the cost of raw materials is only picked up when those materials go through to the retail sector. The retail price index measures a selected basket of items sold in the shops, and by ‘shops’ they don’t mean builder’s merchants.

“But for builders faced with rising materials costs, the fact that they can’t pass this increase onto the customer is not quite so good.”

The building industry is even further out of the loop because house prices are not even included in the inflation index. I suppose there is a good reason for that because houses can be sold on to people who have also benefited from price hikes, but if you are trying to save up for your first house, the rate at which prices are moving away from you is the most relevant bit of inflation there is.

Happily, for first time buyers, house prices are falling or at least static. But for builders faced with rising materials costs, the fact that they can’t pass this increase onto the customer is not quite so good. The only way that increased material costs can be absorbed is in reducing labour costs, or cutting profits. You can guess which is more likely. With high unemployment and a huge army of migrant workers looking for any job they can find, it is wages that end up bearing the brunt of this shortfall.

“Tax Laws Distort The Market”

For anyone looking to have work done on an existing property the fall in labour costs may also offset the rise in materials, but there is another factor which distorts the market – Tax laws. VAT is not charged on new builds, but is charged on home improvements. It is even more biased because small builders are sometimes zero rated for VAT because their turnover is below the threshold.

With VAT now being 20%, this can make a huge difference to a quotation. So although we have a 20% increase in materials there is a possible saving of 20% on labour costs if you turn tax laws to your advantage, and find a builder who is either not VAT registered or is willing to do the job for cash.

Do Tax laws punish the honest builder?

The idea of having a VAT threshold is to encourage start-up businesses, but I know plenty of builders who have been trading for 20 years or so who still manage to keep below the VAT threshold. They do this by working for cash, or getting the customer to buy the materials. Meanwhile, the honest builder (yes there are some) who is forced to charge VAT, loses jobs to the fly by nights.

The obvious answer here is to address unequal tax laws. The government should give the same VAT relief to home improvements, as they do to new build projects, or abolish the VAT threshold. I, and many others in the industry, would prefer tax laws to treat new build and refurbishments equally. It would be a brave move, but one which would give some real stimulus to our industry. At a time when there are skilled tradesmen stacking shelves in supermarkets and people are in desperate need of housing, bold change could make a huge difference.
