Gas Safe registered boiler installation across London and inside the M25. Approved installer for Vaillant and Baxi, so your boiler can be registered for a 10 year guarantee. Installations typically £4,500 to £6,500, with a free remote quote.
We are an approved installer for both Vaillant and Baxi, so we can register your new boiler for a 10 year manufacturer guarantee. Most installers cannot offer that on either brand.
A full installation is typically £4,500 to £6,500 including VAT. We price the job before you commit and the quote costs you nothing. Send photographs of your existing boiler and we can usually quote without visiting.
Typically £4,500 to £6,500 including VAT, depending on the boiler and how much of the existing system needs putting right.
That sits above the £2,000 to £3,000 fixed-price online sellers, and we are not trying to match them. What you get instead is an approved Vaillant or Baxi installation registered for a 10 year guarantee, fitted by a Gas Safe registered and WaterSafe approved contractor rated 4.96 from over 1,200 reviews.
You can get an exact figure without anyone coming to the house. Send photographs and the details, and we will price it free of charge.
We install boilers across London and inside the M25.

The difference between a budget installation and ours is mostly the work around the boiler rather than the boiler itself. This is what we do on every job.
We size the boiler from the radiators, bathrooms and occupants rather than matching whatever was there before. Oversized boilers are common in London and they cycle on and off, which burns gas and wears the boiler out faster. Getting the size right affects your bills more than the efficiency rating on the box.
This is the step most often skipped. A modern combi can draw considerably more gas than the boiler it replaces, and many London properties have a 15mm gas run that suited an old system boiler and will not supply a new combi. If the pipe cannot deliver the volume, the boiler underperforms or locks out, and no amount of servicing will fix it. We calculate the gas rate, upgrade the run where it is needed, and tell you before the job rather than after.
Manufacturers require the system to be cleaned before a new boiler is fitted, and most will decline a warranty claim if it was not. We flush the system, add inhibitor and fit a magnetic filter. Fitting a new heat exchanger onto twenty years of sludge is the quickest way to destroy it.
The flue has to terminate a set distance from windows, doors and boundaries, and where it runs through a void there have to be inspection hatches so it can be seen. The condensate needs a route to a suitable drain, correctly sized and insulated where it runs outside. Get that wrong and you have a frozen pipe and a dead boiler in the first cold week of the year.
We commission the boiler with a flue gas analyser, record the readings, complete the Benchmark book and register the guarantee with the manufacturer. We notify Building Regulations through Gas Safe and you receive the certificate. Without that notification the installation is not compliant, and it surfaces when you come to sell the property.
The Benchmark record matters afterwards too. Your 10 year guarantee depends on the boiler being serviced every year and the record being signed each time.
We are approved for both brands we fit, so see Vaillant installation and Baxi installation for the 10 year guarantee. We also handle boiler repair, boiler service, central heating installation and our rates across London.
A full installation is typically £4,500 to £6,500 including VAT. The figure depends on the boiler, whether the flue or pipework needs altering, and whether you are changing system type. You get an exact price before anything is agreed, and the quote is free.
We are an approved installer for Vaillant and Baxi, so we can register your new boiler for a 10 year manufacturer guarantee. Call 020 3764 2713 and we will talk you through the exact terms before you commit to anything.
Send us photographs and details of your current boiler and we price the job without visiting. It costs nothing and there is no obligation. If the job is unusual we will say a visit is needed rather than guess at it.
A straightforward replacement usually takes a day. Changing system type, moving the boiler, or work that needs pipework altering can take two to three days.
Size first. A boiler matched to the number of radiators, bathrooms and occupants will cost less to run than an oversized one. Then the type, which is combi, system or regular depending on your hot water needs. Efficiency in the UK is rated under ErP, and almost every new condensing boiler sits at A, so the rating rarely separates one from another. Correct sizing and good controls make far more difference to your bills than the label does.
Usually yes, though it means changes to the system. Moving from a regular boiler and cylinder to a combi, for example, means reworking pipework and removing the cylinder and tanks. We will tell you what is involved and what it costs before you decide.
