Plumbers in London

Phone numbers for plumbers and heating engineers covering London — boilers, leaks and bathrooms. Open a profile and call the business yourself. This site does not send your job.

Boiler and gas work should be done by someone whose profile shows Gas Safe. A card that says London may be based in Croydon, Ilford or Harrow. Ask which borough they will actually drive to, and whether the congestion charge and a parking bay are inside the figure. Profiles show a name, the area they cover and a phone number. Public qualifications such as Gas Safe or NICEIC appear only when they are on the profile. Read the cost notes for a sourced national range; a figure on a card is not a quote.

Typical plumbing & heating costs

Heatable’s January–June 2026 quote sample, closed 30 June 2026, put a standard combi replacement around £1,800–£3,500, median near £2,300. That sample is national. It is not a quote from this site. In a conversion flat the combi is often boxed above a shopfront or at the back of a half-landing. Ask whether the price moves the boiler or only swaps the heat exchanger, and who pays for the scaffold tower in the lightwell.

A local rule to check in London

Gas work in England needs a Gas Safe engineer. The Boiler Upgrade Scheme is open in England and Wales and needs an MCS-certified installer, which is not the same mark.

Questions before you phone

How do I find plumbers and heating engineers in London on this list?

Islington still has butterfly roofs over narrow returns, and a mansion block in Maida Vale hides the soil stack in a riser you cannot see from the street. Basement flats often need a long flue run before a boiler can stay where it is. Names, service areas and phone numbers sit on the cards. Open a profile and call the firm yourself. A card that says London may be based in Croydon, Ilford or Harrow. Ask which borough they will actually drive to, and whether the congestion charge and a parking bay are inside the figure.

Does this page send my job to a London plumbing & heating firm?

No. You place the call. This site does not email or text anyone on your behalf.

What should the written price say for plumbing & heating in London?

Make the written quote say where the condensate goes in a basement, whether a pump is extra, and if the gas run has to cross a neighbour's cupboard.

What is easy to miss before booking in London?

Party-wall notices and a suspended bay are the usual extras on a terrace. Conservation streets in a borough such as Kensington can stop a flue from leaving the front elevation.
