London's trusted plumbers — same-day callouts, Gas Safe registered, fixed-price quotes. 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 Plumbing 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.
