Plumbers in London

Phone numbers for plumbers and heating engineers in London — boiler repair, leaks and bathrooms. London boroughs only, not Slough or Reading. Open a profile and phone the business yourself. This site does not send the job.

For a boiler repair or other gas work, look for Gas Safe on the record before you book that part of the job. This London list is the City of London and the 32 London boroughs, including Croydon, Bromley, Ealing and Harrow. Slough, Watford, Reading and Luton are not added to it. 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 before you treat a number as the price. A figure on a card is not a quote from this site.

How to read a price for boiler repair, leaks and bathrooms

Heatable’s London boiler page, updated 12 August 2026, puts an overall average new-boiler cost in London at about £3,700, roughly £1,000 over the national average named on that page. The same page puts a London combi installation at an average of £3,061. In its London postcode table, South East London averages £3,900 and North West London averages £3,125. Heatable’s national guide, updated 9 October 2026, still puts a like-for-like combi swap at £1,800–£3,500, median £2,300, from quotes in January to June 2026, and that sample is not split by city. Victorian and Edwardian terraces, mansion blocks and converted flats are common, so access, parking and how waste leaves the street often sit beside the labour. Ask whether removal, controls and VAT sit inside the London figure. A figure here is not a quote from this site. Checked 14 October 2026.

What to check in London

Gas work in Great Britain has to be done by a Gas Safe registered engineer. The Boiler Upgrade Scheme is open in England and Wales. Ofgem guidance checked 13 October 2026 puts an air-source or ground-source grant at £7,500, taken off the installer’s quote. It is not a gas repair, and it is not a price from this site. Victorian and Edwardian terraces, mansion blocks and converted flats are common, so access, parking and how waste leaves the street often sit beside the labour. Then ask whether the written price matches the job, and whether they will visit your postcode.
