Book nowBeFix aims to repair boilers in Kensington the same day you call, and a Gas Safe registered engineer is usually on site within one to three hours. The engineer finds the fault and explains the cost before starting work. Kensington is part of our wider boiler repair in London service, with the same hourly rates and the same 12-month labour warranty.
Standard daytime rate, per hour
Evening rate, per hour
Night rate, per hour
The hourly rate depends on when the engineer attends, and all three rates above are plus VAT. There is no separate call-out fee: you pay for the time we spend on your boiler, with parts charged on top. We explain the cost before any work starts.


Kensington homes are rarely simple. Many run pressurised systems or unvented hot water cylinders, and getting to the boiler can take some planning.
| Property | Typical set-up | What it means for the repair |
|---|---|---|
| Flats off Kensington High Street | A sealed, pressurised system, often a combi tucked into a kitchen cupboard, sometimes on a wall shared with neighbours | Space is tight, so we work tidily, and when the pressure keeps dropping we find where the water is going before topping the system up |
| Stucco villas in Holland Park | A system boiler, often paired with an unvented cylinder, and long pipe runs over several floors | Faults can sit in the controls, the expansion vessel or the zone valves, so we test the wider system as well as the boiler |
| Mansion blocks towards West Kensington | Shared risers, awkward flue routes and managed entry | Where a repair touches common parts, the freeholder or managing agent may need to approve access first. Tell us when you book and we will plan around it |
| Hard London water | Limescale builds up in heat exchangers and hot water parts over time | It causes noise, weak hot water and overheating, so we check for it on every visit |
| Fault | What you notice | Common cause | What we do |
|---|---|---|---|
| Pressure loss | Gauge below 1 bar, boiler locks out. Ideal shows F1, Vaillant F.22. | Leak, failed expansion vessel, pressure relief valve letting by | Find the loss, repair it and reset the pressure |
| Ignition problems | Boiler will not light or keeps locking out. Worcester Bosch shows EA 227. | Ignition electrode, gas valve, blocked condensate pipe | Test the ignition sequence and replace the failed part |
| Poor circulation | Cold radiators, slow heat, hot and cold spots | Pump fault, sludge, air, sticking valves | Test the pump, clear air and free the valves |
| Worn parts | Error codes that keep coming back. F3 on Ideal points to the fan. | Ageing fan, PCB, sensors or diverter valve | Diagnose the part and fit a replacement |
| Unusual noise | Banging, kettling, whistling or gurgling | Limescale, low pressure, trapped air | Find the source and fix it before it causes damage |
Codes vary by brand and model. Note what the display shows before you reset anything, and tell us when you call.

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![]()
