Kensington & Chelsea heating notes: The borough's hard water is merciless to high-end fittings — scale dulls designer brassware, blocks rain heads and shortens the life of boiling-water taps, so descaling and inhibitors earn their keep here. Kensington & Chelsea's stucco terraces, mansion flats and mews houses are dense with listed constraints, basement conversions and premium finishes — heating and hot-water here is as much about protecting interiors as fixing pipes. Mains supply here is managed by Thames Water.

What a new boiler costs

Expect £1,800–£2,800 for a straightforward combi replacement in the same location, more for conversions and relocations. The quote should always include: the boiler and flue, a magnetic filter, updated controls to current regulation, a chemical cleanse (or powerflush where sludge demands it), condensate connection, commissioning with benchmark record, and building-control notification. If a Kensington & Chelsea quote is dramatically cheaper than the band, check which of those it quietly omits.

Combi, system or heat-only — the honest steer

The rule of thumb that survives contact with reality: one bathroom and reasonable mains pressure, choose a combi; family house where two showers run at 7.30am, choose a system boiler and cylinder; ageing gravity system in a house you're not renovating, a modern heat-only swap can be the pragmatic move. A good installer measures your mains flow before recommending — if nobody's run a tap into a jug, the recommendation is a guess.

Warranties, paperwork and aftercare

The boxes that must be ticked: warranty registered with the manufacturer within the deadline, building-control notification lodged (the Gas Safe notification handles this for gas installs), benchmark commissioning record completed in the boiler's log, and your first annual service booked eleven-ish months out to keep the warranty alive. Network installers do all four as standard — it's a condition of taking installation work through us.

Frequently asked questions

How much is a new boiler in Kensington & Chelsea?

Most Kensington & Chelsea combi replacements land between £1,800 and £2,800 installed; conversions and system-boiler installs range higher, typically £2,500–£4,500. Your fixed quote follows a survey — the quote form on this page captures what the surveyor needs to price accurately.

Which boiler brand should I choose?

The honest answer: any of the major brands at the right size, installed well, will serve you. Differences lie in warranty length, parts availability and price tier. Our brand hub compares them factually — and a good installation matters more than the badge.

Is the quote really fixed?

Yes — after survey, the price is fixed and itemised. The only changes are ones you approve in advance (for example, if opening up reveals pipework that must be brought to standard). Doorstep additions are a breach of network standards, not a negotiating tactic.

Will you take away my old boiler?

Yes — removal and responsible disposal of the old appliance and any redundant tanks or cylinders is included in network quotes. Cylinder and tank removal in conversions is itemised so you can see its share of the price.
