Plumbers in Southampton

Phone numbers for plumbers and heating engineers covering Southampton — 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. Eastleigh and Totton appear on Southampton cards. Portsmouth is a separate list; a firm that says both harbours still has to say which morning is yours. 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. Portswood terraces often have the boiler in a mid-terrace kitchen with the flue toward a lightwell. Shirley semis have an outside wall. Ask which, and whether a dockside flat's boiler is in a landlord's cupboard instead.

A local rule to check in Southampton

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 Southampton on this list?

Shirley and Portswood are 1930s houses and terraces inland from the water. The Itchen and the docks are a different roof and a different parking problem from a Freemantle bay. Names, service areas and phone numbers sit on the cards. Open a profile and call the firm yourself. Eastleigh and Totton appear on Southampton cards. Portsmouth is a separate list; a firm that says both harbours still has to say which morning is yours.

Does this page send my job to a Southampton 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 Southampton?

Lightwell flue, outside wall, or a landlord cupboard. Three different jobs.

What is easy to miss before booking in Southampton?

Bay windows in Shirley leak at the flat roof over the bay. The main tile pitch can be sound. Ask them to look up at the bay before they say 'new roof'.
