In a densely converted terrace a flue that was legal when fitted can stop being legal when a neighbour builds.
No heating or hot water right now? Call 0203 868 6134. We will tell you the earliest realistic slot rather than the one you want to hear.
Two details to start. Add your postcode and whether there is a cylinder in an airing cupboard and we can usually tell you the likely part before we attend.
We cover Hammersmith, and the whole of London

Almost nobody says they live in W6. They say Brook Green, or Ravenscourt Park, or the Bush.

Nothing changed at your house. Something changed next door.
W6 and W12 are big Victorians at high density, most of them divided into flats, with the Shepherd's Bush terraces and the estates around White City behind them. Every one of those conversions put a boiler somewhere, and every boiler needed a flue.
A flue terminal has to sit a minimum distance from anything that opens. Windows, doors, air bricks and the boundary itself all carry a required clearance, so that combustion products cannot get back into a building. When the boiler went in, those distances were met. Then the neighbour extended, or put a window into a side wall, or built up over a side return, and the clearance stopped being there.
Nothing at your house changed and the boiler is not faulty. But at the next safety inspection the installation is classified At Risk, and where it is bad enough it is Immediately Dangerous and gets disconnected. That is a legitimate call by the engineer, and the answer is usually a flue extension or a repositioned terminal rather than an appliance.
At Risk and Immediately Dangerous are defined classifications, not opinions. An engineer must explain which one applies and get your signature before disconnecting anything. If somebody condemns a boiler without telling you which classification and why, ask, and ask for it in writing.
Two very different calls from the same postcode.
Most of the converted flats here run a combi, so hot water that has gone lukewarm and unpredictable while the heating stays perfect is the plate heat exchanger, furred with scale. It is a part rather than an appliance and it is the commonest repair we carry out anywhere.
In a converted house the pipework is often the original house system, older and dirtier than any manufacturer assumes, so a new part fitted into it fails the same way the last one did. And where the conversion left shared pipework between flats, the fault is sometimes not in your flat at all.
Where a whole house kept its cylinder, the ordinary suspects apply: the motorised valve that diverts to the tank, the cylinder thermostat, or the immersion element.
An unvented cylinder is a pressurised store, so working on one is notifiable and needs a G3 qualification on top of Gas Safe registration. Plenty of firms hold one and not the other, which is why a cylinder call so often becomes two visits. Our engineers hold both, so it is one visit and one charge. See unvented cylinder repair.
The one thing a yearly visit genuinely prevents.
London water comes off the Thames and the Lea, both of which run through chalk. It measures roughly 277 milligrams of calcium carbonate per litre, and that figure is much the same across the city.
Where it lands is what differs. In a W6 flat with a combi it furs the plate heat exchanger and the hot water goes lukewarm. In a whole house that kept its cylinder it coats the coil inside the tank instead. Same water, different part, and on the house side a scaled coil reads as a failing boiler often enough that boilers get condemned for it.
Age does not decide it. The failed part does.
A pump, a diverter valve, a thermostat or a fan is a repair on almost any appliance, whatever its age. A failed main heat exchanger on a boiler well past ten years is the point where the arithmetic stops working, and we will tell you that rather than sell you the repair.
Where a boiler has been classified At Risk on a flue clearance, replacing the appliance changes nothing, because the new one needs the same clearance in the same place. The question to settle first is whether the terminal can be extended or moved to a compliant position. Get that answer before anybody quotes for a boiler.
Our boiler replacement page sets out what a replacement actually involves, including what changes when a stored system is converted, and the costs guide explains what moves the figure.
That answer costs nothing. It is the one most people ring us for. Call 0203 868 6134.
Next door to here we cover Chiswick and Bedford Park and Fulham and Parsons Green. Everything else is on boiler repair in north London and areas we cover.
These are where we work most, not a boundary. An engineer attends anywhere in north London and south London. Tell us where you are and we will say plainly when we can get to you.
Been told your boiler is At Risk?
That is a classification, not a condemnation, and the commonest cause here is a flue too close to a window. Tell us what the notice says and we will tell you what it actually means.
If you smell gas: do not touch any switches. Open the windows, leave the property, then call the National Gas Emergency Service on 0800 111 999. That line is free and open 24 hours. Call them before you call us.
If a carbon monoxide alarm is sounding: get everyone out immediately, then call 999 if anyone feels unwell. Do not go back in until the property has been ventilated and checked.
If the boiler locks out repeatedly: try one reset. If it locks out again straight away, stop. Repeated resets hide a fault that is still there, and on a gas appliance that is not a risk worth taking.
Under the Gas Safety (Installation and Use) Regulations 1998, only a Gas Safe registered engineer may work on gas appliances. Never open the boiler casing yourself.
Yes. The names listed above are the ones we hear most, and they are nowhere near a complete list. We work right across London, north and south of the river. Ring and tell us the address and you will get a straight answer about timing.
At Risk is a defined classification meaning the installation could become dangerous, not that the appliance is broken. Here the commonest cause is a flue terminal that no longer has the required clearance from a window, door, air brick or boundary, usually because a neighbour extended or added an opening after the boiler went in.
Because the clearance is measured to whatever is there now, not to what was there when the boiler was fitted. If a neighbouring window, extension or air brick has appeared inside the required distance, the installation stops complying through no act of yours. It is still a legitimate classification.
Almost never. A new appliance needs the same clearance in the same place, so replacing it changes nothing. The answer is usually a flue extension or a repositioned terminal. Settle that before anybody quotes for a boiler.
Almost certainly not. On a combi that is the plate heat exchanger furred with scale, so the boiler cannot get heat across into the water fast enough. Flushing or replacing it costs a fraction of an appliance.
Yes, and every other major make, including the ones most firms will not touch. Those two and Baxi are what we open most in W6 and W12. Main, Ariston, Ferroli, Vokera, Biasi and ATAG all turn up here too. If your boiler is showing a fault code, the brand pages explain what it means.
Yes, and on the same visit where the appliance passes, so a let property is not off the market twice. See landlord gas safety certificates. If it has no gas supply we cover electric boilers as well.
The line is answered 24 hours a day by a technical customer service member, not a call centre reading from a script. If a boiler has been disconnected on safety grounds we will tell you on the phone what is likely to be needed to get it back on, rather than making you wait to find out.
Every major make, and the fault code pages often name the part before you ring.
The converted flats run combis sized to fit a cupboard, so Worcester Bosch, Ideal and Baxi are what we open most, with Vaillant common in the better refits and the whole houses.
We also work on the makes most firms will not: Main, Ariston, Ferroli, Vokera, Biasi and ATAG all turn up in W6 and W12, usually because they fit where nothing larger would. Parts for every one of them are still obtainable.
If your boiler is showing a code, the make decides what it means. A Worcester Bosch EA and an Ideal L2 are different faults with different fixes. Each brand page lists the codes for that make and what causes them.
The full list is on our boiler brands page, and general repairs are on boiler repair in London.
Tell us where you are and whether there is a cylinder in an airing cupboard. With those two answers we can usually name the likely part, give you the rate, and book somebody in, all on the one call.
