Covering South East and Greater London
Reliable London plumbers
and drainage engineers
for period and modern homes
From Bromley and Bexley through Greenwich, Lewisham, Croydon and out to South West London — Total Flow handles the city's most awkward plumbing with the calm of a team that's seen it before.
Local coverage
London plumbing is its own discipline — and we work it daily
London plumbing is a different beast from a regular suburban job. You're working in flats above flats, around shared stacks, through Victorian conversion mazes, against tight parking, congestion charging, low-emission zones and concierge schedules. We've structured our service for exactly that.
Our London catchment runs heaviest through Bromley, Bexley, Greenwich, Lewisham, Croydon and Southwark, with regular work into Wandsworth, Lambeth and the East End.
London also has its own infrastructure quirks: low mains pressure in older boroughs, lead supplies still in service, tight risers in mansion blocks, and basement waterproofing that has to be designed not just plumbed.

What we see in London
Plumbing problems that London property throws up — and how we fix them
London's mix of building age, density and infrastructure pressure creates predictable failure patterns.
Mansion blocks and conversions above the third floor often suffer pressure drop. We diagnose between mains, riser, PRV setting and combi sizing.
Many pre-war London homes still have lead supplies. We replace and certify to current WRAS standards.
Conversion flats sharing a single stack create constant blame games. We use CCTV to prove cause and location.
Twin-pump sump systems with battery backup — the only safe spec for a habitable basement.
Sympathetic stack and soil routing to keep heritage officers happy.
London water is hard. Combi heat exchangers fail early without softening.
