Fulham’s mix of Victorian terraces and riverside flats means no two boiler jobs look quite the same, but the price always lands somewhere between £1,500 and £3,750 (+VAT), confirmed by our Gas Safe registered engineers (No. 967796) after a free survey, part of our wider Boiler Installation in London coverage. Worcester Bosch, Vaillant, Ideal and Baxi installs come with up to 12 years’ manufacturer warranty, on top of our own 12-month workmanship guarantee, since we’re an accredited installer for all four.
All-in-one and compact, the usual fit for smaller Fulham flats and conversions.
Boiler installation costs in Fulham aren’t set to a single number. The final price depends on the boiler type, your existing pipework and the scope of the job. We confirm your exact price in writing after a free home survey, with nothing added once work begins. A straightforward like-for-like swap usually sits at the lower end of these ranges; a relocation or a conversion from a regular system to a combi tends to sit toward the top. Flexible finance is available through our approved partners, letting you spread the cost over monthly instalments rather than paying the full amount upfront.


Fulham’s housing stock is unusually mixed for a single area of London. Around Eel Brook Common you’ll find rows of Edwardian and Victorian terraces, often with a boiler that’s been relocated more than once. Closer to the river near Putney Bridge, riverside apartment blocks bring different challenges: tighter service risers, shared flues, and building-management sign-off before work starts. Newer developments across the borough are usually the most straightforward, with modern pipework and easy boiler access already in place.
| Property type | Typical setup | Installation consideration |
|---|---|---|
| Edwardian/Victorian terrace (e.g. near Eel Brook Common) | Original chimney breast or a previously relocated boiler, older pipework | Often needs a pipework check and updated flue routing before we can quote |
| Riverside apartment (e.g. near Putney Bridge) | Compact service riser, shared building flue | Building-management approval and access booking usually needed in advance |
| Modern new-build | Purpose-built utility space, standard pipework | Usually the fastest, most straightforward installation |
There’s also a practical scheduling factor specific to this part of London: Fulham sits inside the Ultra Low Emission Zone, which covers every London borough right up to (but not including) the M25.
This doesn’t change which boiler you can have, but it can affect installation-day logistics. A non-compliant works van faces a daily charge, and on-street parking near the property can be tight on some Fulham roads. We factor both into your installation date when we book the job.

We install all major boiler brands, with particular focus on four: as an accredited installer of Worcester Bosch, Vaillant, Ideal and Baxi, we can register the longer manufacturer warranties directly on your behalf. We also fit Keston, Remeha, Main and Viessmann where that’s the better fit.
Being an accredited installer for Worcester Bosch, Baxi, Vaillant and Ideal means these manufacturers have vetted our engineers directly, which is also usually needed to unlock their longer extended warranties. If you’re renewing the wider heating system at the same time, our central heating installation team can handle radiators and pipework alongside the new boiler.

I’d had various concerns about my aircon system at my flat in NW2 not working effectively, and was very relieved when Befix were able to offer a prompt service appointment. Communication in advance of the appointment was good and engineer Vahid arrived punctually and worked carefully and thoroughly, ensuring the whole system was in good working order. He was clearly knowledgeable about all kinds of technical issues, friendly and adaptable, and I had confidence that he was attending to everything properly. I am not perhaps very familiar or up to date with what I should expect to pay for this kind of work. I think the price was probably fair - but I would advise checking in advance to make sure you are happy with the arrangement. I was left feeling relieved my system was now in good working order, and will certainly consider the company again for future work, including more ambitious projects.Posted on Google![]()

Vahid was kind, professional, and incredibly good at his job. He came quickly and flexibly to west london/ Kensington area— and worked out the most economic and quickest way to help with a boiler that lost its pressure. Could not recommend this service more!Posted on Google![]()

A new boiler installation in Fulham typically costs between £1,500 and £3,750, depending on the boiler type and how much pipework needs changing. Combi boilers usually sit toward the top of that range for larger properties, while system and regular boiler swaps typically run £1,500 to £3,500. We confirm your exact price in writing after a free home survey.
Most straightforward installations in Fulham are completed within 8 hours, in a single working day. More complex jobs, such as relocating the boiler or converting from a regular system to a combi, can take longer, and we'll always confirm the expected timeline during your free survey.
Riverside flats near Putney Bridge often suit a combi, since space is tight and there's usually no room for a cylinder, though building-management approval is worth checking first. Edwardian and Victorian terraces around Eel Brook Common more often keep a system or regular boiler where the existing cylinder is in good condition. We'll recommend the right fit during the free survey.
Yes. BeFix is Gas Safe registered under number 967796, and every engineer who installs your boiler is Gas Safe qualified for the work they carry out. We're also fully covered by public liability insurance.
Yes, flexible finance is available so you can spread the cost of your new boiler over monthly repayments instead of paying the full amount upfront. Ask your surveyor about the options available when you book your free assessment.
Every installation includes a 12-month BeFix workmanship guarantee alongside up to 12 years' manufacturer warranty, depending on the boiler model. We handle the warranty registration for you as part of the installation.
In most cases, no; relocating a boiler is usually covered under permitted development rights. If your Fulham property is listed or sits within a conservation area, we'll flag this during the free survey and advise whether anything extra is needed before we schedule the installation.
