Primrose Hill runs the full range, from Regency terraces near Chalcot Square to tight mews houses and newer flats by Regent’s Park Road, and BeFix fits boilers in all of them. Installations start at £1,500 (+VAT), carried out by our Gas Safe registered engineers (No. 967796), as part of our wider Boiler Installation in London service. A free site visit and written quote come before anything is booked, and finance is available if you’d rather spread the cost.
All-in-one and compact, the usual fit for Primrose Hill flats and conversions.
These are ranges, not fixed prices. The final figure depends on things like flue length, whether pipework needs upgrading, and whether the new boiler goes in the same spot as the old one or somewhere new. A like-for-like swap in a modern flat near Regent’s Park Road sits at the lower end. Relocating a boiler in a period terrace, or converting from a regular system to a combi, costs more because of the extra pipework and flue work involved. We’d rather explain what’s driving the number than advertise a low monthly figure that doesn’t reflect the total job. A written, itemised quote follows your free survey, before anything is booked. If you’d prefer to spread the cost, finance is available subject to status. Ask about the current terms during your survey.


Primrose Hill mixes three quite different types of housing: the pastel-painted Regency and Victorian terraces around Chalcot Square, mews houses tucked behind the main streets, and newer flats closer to Regent’s Park Road. Each needs a different approach to installation, not just a different boiler.
Most of Primrose Hill sits inside the Primrose Hill Conservation Area, which also carries an Article 4 direction. In practice, that means some external changes, including repositioning a flue on a period terrace, need planning permission rather than being automatically allowed, unlike in many other parts of London. We check this at the free survey stage rather than assuming permitted development rights apply.
| Property type | Typical boiler type | What to check |
|---|---|---|
| Period terraces (Chalcot Square area) | Regular or system, or combi if the cylinder is being removed | Flue repositioning may need planning permission under the conservation area's Article 4 direction |
| Mews houses | Combi, given limited space for a cylinder | Tight internal access can limit which models physically fit |
| Modern flats (Regent's Park Road area) | Combi | Simpler flue routing, though leasehold consent may still apply |
An engineer visits to check access, existing pipework and the best position for the new boiler.
A clear price breakdown before any work is booked in — no vague "from" figure.
Most straightforward swaps take around 8 hours and are completed within a single working day; more complex jobs may need longer.
All work carried out under registration number 967796.
Every new boiler is commissioned, tested and registered — a gas safety certificate is available if you need one.
12 months' workmanship cover from BeFix, plus up to 12 years' manufacturer warranty depending on the model.
We supply and fit boilers from eight manufacturers, and we’re an accredited installer for four of them: Worcester Bosch, Baxi, Vaillant and Ideal. This means those manufacturers have checked our installation standards directly and back our work with their longer warranty tiers. Which brand suits your home depends on the boiler type you need and your budget. We’ll talk through the options at your free survey rather than pushing one brand by default.

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![]()

Vahid was very fast to respond to my quote request and to set a time for his visit. He fixed our boiler in a very efficient and professional manner. He already had the replacement part with him beforehand which was very helpful. I would 100% recommend BeFix!Posted on Google![]()

Combi boilers typically cost £1,500 to £3,750, and system or regular boilers £1,500 to £3,500, depending on the job. Your exact price comes from a written quote after a free site visit, not a fixed headline figure.
Most installations are completed in a single working day, around 8 hours, for a straightforward swap. More complex jobs, like relocating the boiler or converting from a regular system to a combi, can take longer.
Period terraces around Chalcot Square often suit a regular or system boiler, especially where a cylinder is already in place, while modern flats near Regent's Park Road usually suit a combi. We confirm the right fit, and check whether Primrose Hill's conservation area status affects flue positioning, during your free survey.

Every installation includes a 12-month labour warranty from BeFix, on top of up to 12 years' manufacturer warranty depending on the boiler model.
Yes. Most of Primrose Hill sits within a conservation area with an Article 4 direction, so we check whether a new external flue position needs planning permission before booking any work, rather than assuming permitted development rights apply.
