Safety first — read this before anything else

Smell gas? Do not touch any switches. Open the windows, leave the property and call the National Gas Emergency Service on 0800 111 999. That line is free and open 24 hours. Call them before you call us.

Carbon monoxide alarm sounding? Get everyone out immediately, then call 999. Do not go back inside until the emergency services say it is safe.

Boiler locking out repeatedly? Try one reset only. If it locks out again straight away, stop resetting and call an engineer. Repeated resets mask a fault that is still live.

No heating or hot water right now? Call 0203 868 6251. Lines are open 24 hours and we will tell you the earliest realistic slot.

What we repair in Kensington and Chelsea

Boiler repair Kensington and Chelsea means working in five square miles of almost entirely period housing. The boiler you have is usually a consequence of what the building was before it was converted.

Stucco terraces split into flats

Brompton, Courtfield and Queen’s Gate were built as single houses and are now mostly flats. That conversion dictates the heating: a combi squeezed into a kitchen cupboard or hall press, a long horizontal flue run out to a rear elevation or light well, and a filling loop somewhere inconvenient.

Five and six storey buildings split into flats also put the top-floor boiler a long way above the mains, which is why pressure complaints cluster at the top of the building rather than the bottom.

Edwardian mansion blocks

The blocks around Earls Court and Courtfield are a different job. They tend to run system boilers with hot water cylinders in airing cupboards, sometimes on a communal riser.

Access usually runs through a porter or managing agent rather than the resident, and some buildings set working hours for contractors. Tell us the arrangement when you book.

Riverside apartments and heat interface units

Chelsea Harbour and the newer blocks off Lots Road are different again. Some apartments have a heat interface unit rather than a boiler — a plate exchanger fed from a central plant room, not an appliance that fires.

Say so on the phone if that is what you have. It is a different job and the fault may sit with the building rather than your flat.

Mews houses and North Kensington

North of the Westway, Oxford Gardens and St Quintins in W10 hold more mixed stock, including post-war blocks with older regular boilers and back boilers still being replaced.

The mews behind Cheyne and Hans Town bring their own problem: no frontage for a van, and a boiler on an upper floor with a flue that has nowhere obvious to terminate.

Did you know

A heat interface unit has no burner, no flue and no gas supply. If yours has stopped producing hot water, the fault is often in the building’s plant room rather than your flat — and knowing that before we attend saves you a wasted visit.
Whatever the building, call with the make, the model and any code on the display. Most of what we need to bring is decided on that call.

Common faults in Kensington and Chelsea properties

These are the calls that come in most often from this borough. Each one traces back to the housing stock above.

Hot water that runs hot, then cold

The borough is on hard water. Scale builds on the plate heat exchanger inside a combi and the hot water side loses its ability to hold temperature. It is the single most common call we take from SW3, SW7 and W8, and it is a repair rather than a replacement.

Pressure dropping in top-floor conversion flats

A tall terrace split into flats puts the highest boiler a long way above the incoming main. A slow drop is usually an expansion vessel that has lost its charge, not a leak.

Frozen condensate on long external runs

Where a flue and condensate have been routed out to a rear elevation or down a light well, the pipe is exposed. The boiler locks out in a cold snap and clears once thawed, but the run needs lagging or it repeats next winter.

Diverter valve faults

Common in the smaller conversion flats where one combi serves a shower and a kitchen.

Scaled immersion elements and cylinder faults

Frequent in the Earls Court and Courtfield mansion blocks, again a hard water consequence rather than a failing appliance.

No hot water from a heat interface unit

In the newer Chelsea Harbour and Lots Road apartments this usually points at the building plant rather than your flat.

Mansion blocks and portered buildings: if access runs through a porter or concierge, or the building sets working hours for contractors, tell us when you book so we can plan entry properly. Call 0203 868 6251 and we will work around it.

Not sure which of those it is?

Call and describe what the boiler is doing. We will tell you what is likely involved before anyone attends.

Boiler service Kensington

Hard water is the reason an annual service pays for itself faster here than in most of London.

A boiler service Kensington properties actually benefit from is one that looks at scale. We check the plate heat exchanger, the state of any magnetic filter, and whether the system still holds enough inhibitor to protect itself. On cylinder systems we check the immersion and the expansion vessel.

What you get afterwards

A written record of the findings. If we spot a fault we explain the options and confirm the cost before touching anything — a service and a repair are separate jobs and we do not merge them on the invoice.

When to book it

Late summer or early autumn. Once the first cold week arrives the same engineers are on breakdowns and a routine service waits behind them. Full detail is on our boiler servicing page.

Did you know

Hot water that runs hot, then cold, then hot again is usually scale on the plate heat exchanger rather than a boiler on its way out. It is the most common call we take from SW3, SW7 and W8, and it is a repair, not a replacement.

Boiler installation Kensington

This is where the borough is genuinely harder to work in than anywhere else in London, and it is worth understanding before you collect quotes.

Conservation areas and where a flue can go

Close to three quarters of the Royal Borough sits inside one of its 38 conservation areas, with Article 4 directions across large parts of it.

A boiler installation Kensington homes need is often not a simple swap. Moving an appliance to a different wall can put a flue on a protected elevation, and that is a planning question before it is a heating one. On a like-for-like replacement in the same position it usually is not an issue at all.

Mansion blocks and mews

In a mansion block a flue route may cross common parts and need the freeholder or managing agent’s consent. In a mews house there may be no external wall that works at all without a vertical flue through the roof.

How we quote

We confirm the scope first, usually from photographs and a few questions, then give you a written quote before an install date is booked. What is included is set out on our boiler installation page.

If the system shows signs of sludge we will say whether a power flush is worth doing first — and if it is not, we will say that too.

Replacing because it keeps breaking down?

Get it diagnosed first. Repeat lockouts in this borough are often condensate or scale rather than a failing appliance, and both are repairable. If it genuinely is beyond economic repair we will tell you plainly — see emergency boiler repairs if it has stopped altogether.

Landlords and managing agents in Kensington and Chelsea

A large share of the borough’s housing is let, and much of it is managed rather than owner-occupied.

CP12 gas safety recordsIssued after inspection and sent to you and the managing agent, so the compliance file stays current.
Portfolio and block bookingsSeveral flats in one mansion block get scheduled together rather than four separate visits.
Porter and concierge accessTell us the arrangement and any permitted working hours and we plan around them.
Tenant schedulingWe can contact the tenant directly to arrange a window if that is easier for you.

Validity, tenant copies and what happens if an appliance is classed as unsafe are covered on our landlord gas safety certificate page.

Boiler brands we repair in Kensington and Chelsea

Conversion flats across the borough run mostly wall-hung combis; the mansion blocks run more system and cylinder setups. We hold parts for all of these.

Older appliances included. If the parts still exist we can usually source them — see all boiler brands we repair.

Kensington and Chelsea boiler repair FAQs

Do you cover all of Kensington and Chelsea?

Yes. We handle boiler repair Kensington and Chelsea wide, from Chelsea and World’s End in SW3 and SW10 through South Kensington and Queen’s Gate in SW7 to Notting Hill, Ladbroke Grove and North Kensington in W10 and W11. Call with your postcode and we will confirm availability.

My flat is in a mansion block with a porter. How does access work?

Tell us when you book. In the Earls Court and Courtfield blocks in particular, access often runs through a porter or a managing agent, and some buildings restrict contractor hours. We plan around whatever the arrangement is, but we need to know before an engineer is dispatched.

Will a conservation area stop me replacing my boiler?

Not usually, if the new appliance goes where the old one was. It becomes a question when the boiler moves and the flue would terminate somewhere new, particularly on a visible elevation. Given how much of Kensington and Chelsea is covered, we raise it before quoting rather than after.

My hot water goes hot then cold. Is the boiler failing?

Usually not. In this borough it is most often scale on the plate heat exchanger, a hard water consequence rather than a dying appliance. It is repairable. We diagnose first and tell you whether it is a clean, a part or a replacement before any work starts.

Do you cover Chelsea Harbour and the newer riverside apartments?

Yes, but check what you have first. Some of those apartments run a heat interface unit fed from a communal plant room rather than an individual boiler. If yours does, say so when you call, because it is a different job and the fault may sit with the building rather than your flat.

Can you issue a CP12 for a rental property in the borough?

Yes. We carry out landlord gas safety checks throughout Kensington and Chelsea and issue the Landlord Gas Safety Record after the inspection. If you hold several flats in one block we will schedule them in a single run where we can.
