Book nowBoiler broken in Highgate? BeFix’s Gas Safe engineers usually turn up the same day, normally within one to three hours. Pricing works on an hourly rate depending on when you’re booked in, plus parts, and we’re part of a wider boiler repair in London service. Before anyone touches the boiler, the engineer tells you what’s wrong and what it’ll cost.
Standard daytime rate, per hour
Evening rate, per hour
Night rate, per hour
Rates run by the hour, based on when your engineer turns up, as shown above. Parts sit on top of that, billed separately. Once your engineer’s diagnosed the fault, you’ll hear the cost before any work starts, so the decision stays with you.


Highgate has two quite different kinds of boiler to deal with. Older flats around Highgate Village and the cemetery tend to have one type of setup, and the bigger family houses near Archway Road have another. They break down for different reasons too.
| Property | Typical set-up | Where faults tend to start | What it means for the repair |
|---|---|---|---|
| Older flats near Highgate Village and Highgate Cemetery | Compact wall-hung boiler, often a combi, in a cupboard or kitchen | Limescale on the hot-water side (London water is hard), pressure drops, flue and ventilation constraints | Little room to work, so access and flue routing shape the fix |
| Family houses around Archway Road | Often a larger system or regular boiler with a cylinder and many radiators | Sludge and poor circulation, pump and valve wear, slow pressure loss from more joints | The whole circuit matters, so diagnosis follows the water round the system, not just the boiler |
Same complaint, different cause. “No hot water” in a cupboard combi usually isn’t the same problem as “no hot water” in a five-bedroom system, which is why we diagnose first instead of guessing from the symptom alone.
Boilers stop working for a handful of recurring reasons. Here’s what usually causes a boiler to lose heat or hot water.
| Fault | What you'll notice | Usual causes |
|---|---|---|
| Pressure loss | Gauge dropping below 1 bar; heating cuts out | A leak, a failing expansion vessel or a faulty pressure relief valve |
| Ignition problems | Boiler tries to fire, then locks out; no heat or hot water | Worn ignition electrode or flame sensor, blocked condensate pipe, interrupted gas supply |
| Poor circulation | Radiators heat unevenly or slowly, cold spots | Sludge, a failing pump, airlocks or a stuck valve |
| Worn parts | Noises, intermittent operation, hot water fading | Diverter valve, pump, fan or circuit board wearing out |
Fault codes aren’t universal; they vary by brand. On a Vaillant, F22 points to low water pressure and F28 to an ignition failure. On an Ideal, L2 means an ignition lockout. Take the code as a clue, not a diagnosis, and check your manual before you try resetting anything.

BeFix’s registration number is 967796, and you can look it up on the Gas Safe Register yourself rather than take our word for it. We’re insured too, so you’re covered while the engineer’s in your home. Between them, our engineers have put in more than ten years fixing the kind of setup Highgate throws at them, cupboard combis in Village flats, bigger systems in the Archway Road houses, and everything in between. None of that’s optional, either: gas work has to be done by someone Gas Safe registered, full stop.

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![]()

Excellent in every respect. If you need a top plumber in South East London then BeFix come highly recommended. A tricky job which had not been solved by previous professional, was immediately diagnosed by BeFix which has saved me money and time. Efficient, punctual, and reasonably priced.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![]()

Took some trial and error and a few visits, but in the end it was done. He visited on short notice which was very helpful.
£95 + VAT an hour between 7am and 5pm, £125 + VAT from 5pm to 9pm, and £160 + VAT overnight until 7am. Parts come on top of that. Your engineer tells you the cost once they've worked out what's wrong, before touching anything.
No separate fee, just the hourly rate for whichever time slot you're booked in, plus parts. You'll know the full cost before any repair starts.
Same day, usually within one to three hours of your call. Book outside 7am to 5pm and you're into the evening or overnight rate, so it's worth calling to check what's available.
Yes, any type, including older models and ones the manufacturer's warranty no longer covers.
Yes, BeFix's registration number is 967796, and we're fully insured. Check it yourself on the Gas Safe Register site, or just ask the engineer for their ID card when they arrive.
Usually a leak somewhere in the system, or a part like the expansion vessel or pressure relief valve giving up. Topping it up again and again just masks the problem, so it's worth getting an engineer to find where it's actually coming from.
If the fault's specific and the boiler's otherwise fine, repair usually makes sense. If it's old, keeps breaking, or needs a pricey major part, replacement might work out better. Once we've diagnosed it, you'll have a real repair cost to weigh against that decision.
