Family-run London plumbers with Gas Safe engineers, fixed prices and no call-out fee in normal hours. Free, no-obligation quotes across Greater London.
Most problems come from cut corners — the wrong materials, rushed work, or a "guarantee" that vanishes with the van. Thameside Plumber was built to be the opposite: one experienced local team that does the job properly the first time, prices it honestly, and stands behind it in writing.
That's why most of our work still comes the old-fashioned way — from neighbours recommending us.
From the everyday to the emergency — all backed by our 1-year written guarantee.
Fast, local response to burst pipes and plumbing emergencies across Greater London — no national call centre in the way.
