Boiler Installation in Central London
Fixed price combi boiler installation for Central London flats, mansion blocks, townhouses and small commercial premises — fitted by Gas Safe registered engineers who know how to work in restricted buildings without disruption.
How much does boiler installation cost in Central London?
Combi boiler installation in Central London starts from £1,399, fully supplied and fitted, with your thermostat, chemical inhibitor, scale reducer, copper pipework and Gas Safe certificate all included in that one price. There are no call-out charges and nothing added once the engineer is on site. Larger boilers for bigger properties or higher hot water demand go up to £2,699 — the exact price depends on the boiler size and brand you choose, not on where in Central London you live.
Boiler Installers Who Know Central London Properties
Central London homes are not like the rest of the city. Mansion block flats, Georgian townhouses and listed buildings all come with their own access, consent and space restrictions — and it shows the moment an engineer who hasn't worked here before turns up. We install boilers across every Central London postcode, every week.

Central London Boiler Installation — Common Questions
Can I install a combi boiler in a listed building in Central London?
Yes, in almost all cases. Flue position is usually the only sensitive point on a listed building, and our engineers route pipework and flues discreetly to keep the building's character intact, working alongside your freeholder or managing agent where consent is required.
How long does boiler installation take in a Central London flat?
A straightforward like-for-like combi swap is usually completed in 4 to 6 hours. Installations involving a house move, new pipework, or restricted building access can take a full day.
Do I need permission from my freeholder or managing agent?
Most mansion blocks and managed buildings in W1, WC1 and WC2 require the managing agent to be notified before gas work begins. We provide our Gas Safe registration and insurance certificate directly to your building management to speed this up.
What size boiler do I need for a Central London flat?
Most one and two bedroom flats are well served by a 24kW to 28kW combi boiler. Larger Georgian townhouses with multiple bathrooms typically need 30kW or above. Call us free and we'll size it correctly before you pay anything.
Do you offer same day boiler installation in Central London?
Yes, subject to engineer availability and building access arrangements such as concierge booking or loading bay restrictions common in W1 and WC2. Call in the morning and we'll confirm same day or next day availability for your postcode.
