Covering South East and Greater London
Reliable London plumbers,
drainage and boiler 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. Same-day attendance on most emergency calls.
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 — vans compliant with ULEZ, fixed parking budgets baked into quotes, and engineers who can talk to a building manager as competently as they can talk to a homeowner.
Our London catchment runs heaviest through Bromley, Bexley, Greenwich, Lewisham, Croydon and Southwark, with regular work into Wandsworth, Lambeth, Tower Hamlets and the East End. Whether it's a converted Victorian terrace, a 1930s mansion block, a new-build apartment in Canary Wharf or a basement extension in Dulwich — we've worked the property type before and we carry the right parts.
London also has its own infrastructure quirks: low mains pressure in older boroughs, lead supplies still in service, tight risers in mansion blocks, listed-building constraints in conservation areas, and basement waterproofing that has to be designed not just plumbed. We handle all of it.

Why London chooses us
London chooses us when the last firm let them down
A large share of our London work is from clients whose previous plumber over-promised, under-delivered, or vanished mid-job. We arrive when we say we'll arrive and quote what the work is genuinely worth.
From SE postcodes through SW and into the East End — we work the city, not just suburbia.
Realistic ETAs for traffic. We don't promise 30 minutes in central London because no one can deliver it.
Parking, congestion and access costs are included in the quote — no surprise line items.
Same guarantee in Mayfair as in Mottingham — every job, fully covered.
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. Here's what we resolve most weeks.
Mansion blocks and conversions above the third floor often suffer pressure drop. We diagnose between mains, riser, PRV setting and combi sizing — and recommend the genuine fix rather than slapping on a pump.
Many pre-war London homes still have lead supplies from the stopcock to the rising main. We replace and certify to current WRAS standards, often without needing to lift the whole floor.
Conversion flats sharing a single stack create constant blame games. We use CCTV to prove cause and location — and resolve it without the neighbour dispute escalating.
Basement extensions are everywhere in South and West London. We install and maintain twin-pump sump systems with battery backup — the only safe spec for a habitable basement.
Flue routing through stucco, brick or listed facade is a planning minefield. We work the constraints — internal flues, alternative routing, rear-stack relocation — to keep heritage officers happy.
London water is hard. Combi heat exchangers fail early without softening. Almost every install we do in zones 2–6 includes scale protection as standard.

London FAQs
Answers to what London homeowners ask us most
Do you cover all of London?+
Our heaviest coverage is South East and South London — Bromley, Bexley, Greenwich, Lewisham, Southwark, Lambeth, Croydon, Wandsworth and Merton. We also cover East London regularly and West and North London by appointment. If you're inside the M25 and inside ULEZ, we'll get to you.
How fast can you reach me in London?+
Inner-London emergencies typically 60–90 minutes accounting for traffic. SE London suburbs (Bromley, Bexleyheath, Eltham) often inside 45 minutes. We give honest ETAs — we won't promise 30 minutes through Elephant & Castle at rush hour and then arrive at 4pm.
Are your vans ULEZ compliant?+
Yes, every London vehicle meets ULEZ and LEZ standards. You won't see a 'congestion surcharge' or 'ULEZ recharge' line on the invoice — it's all built into the fixed quote.
Can you work with our building manager or freeholder?+
Yes, regularly. We send insurance documents, Gas-Safe IDs and method statements ahead of arrival when required, and we work within building access windows. Managing agents across SE London use us as their first call.
Do you work on listed and conservation-area properties?+
Often. We've routed flues, relocated stacks and re-plumbed period bathrooms across conservation areas in Greenwich, Blackheath, Dulwich and Crystal Palace. We work to preserve the fabric, not just hit the spec.
What does a typical London plumbing job cost?+
London jobs cost slightly more than wider Kent due to travel and parking, but we keep it transparent. A blocked drain in SE London is typically £200–£320. A combi boiler installed is £2,400–£3,800 fitted depending on spec. Every quote is written before work starts.
Do you handle basement flooding and sump systems?+
Yes — extensively. Twin-pump sump installations with battery backup, non-return valves, and gravity-fail alarms. Basement waterproofing is one of our biggest London workstreams.
Can I get a CCTV survey for a London home purchase?+
Yes, same or next day across South and East London. Full recorded video and a written report your conveyancer can use to negotiate or proceed with confidence.
Are you Gas-Safe registered?+
Yes. Full Gas-Safe registration with ID carried on every job. We're WRAS-trained for water regulations and carry £5m public liability cover — proof sent ahead on request.
Can you handle out-of-hours emergencies in London?+
24/7, 365 days. Real engineers on a rota — not an answering service that calls a sub-contractor at 2am. Out-of-hours pricing is fixed and quoted before we dispatch.
