Most London plumbing repairs fall into a few familiar groups: leaks between flats, dripping taps and sticky valves worn by hard water, toilets that never stop refilling, blocked basins in busy shared houses and old stopcocks that refuse to turn just when they're needed. Behind almost all of them are two things – the age of the city's housing and the water that runs through it.
The good news is that most repairs are quick when they're caught early. A weeping joint under a sink is a short job; the same joint left for six months can mean a new kitchen floor. Describe what's wrong, add a photo or two if you can, and compare quotes from London plumbers who do repairs and maintenance in your borough.
Leaks between flats, hard water and old stopcocks
In converted houses and purpose-built blocks, a slow leak from a shower tray, toilet or waste upstairs can soak into ceilings below for weeks before anyone notices. Plumbers spend a lot of time tracing these leaks – testing showers, wastes and supplies in turn – and the sooner they're reported, the less damage there is to put right.
London's hard water wears out the moving parts of taps, cisterns and showers faster than in soft-water areas. Ceramic cartridges start to drip, fill valves stick and thermostatic showers lose their accuracy. Replacing the worn part is usually straightforward, and many plumbers suggest a scale reducer or softener if the same repairs keep coming back.
Many homes also still have original stopcocks and lead or iron supply pipes. A seized stopcock is the last thing you want during a burst pipe, so replacing it – and, where the budget allows, the old supply pipe – is one of the most worthwhile bits of maintenance you can book.

While you wait for a plumber
- Turn off the isolating valve on the affected fitting, or the stopcock if water is escaping.
- Take photos of the leak, the fitting and any damage, and note when the problem happens.
- Move valuables away from the area and put down towels or a bucket.
- Check whether your home insurance covers escape of water or trace and access.
Water supply in London
Most of London's water comes from the Thames and Lea and the chalk beneath the city, so it is hard. Limescale builds up in kettles, shower heads, thermostatic valves and combi boiler heat exchangers, and plumbers here are regularly asked to descale or replace parts, or to fit a water softener. The capital also has a huge stock of pre-war homes where old lead or iron supply pipes, shared supplies and tired stopcocks still turn up.

Plumbing repairs in London: common questions
My London stopcock won't turn – what should I do?
Don't force it, as old stopcocks can snap. Ask a plumber to replace it, and in the meantime find out where your external stop tap is in case of an emergency.
How quickly can I get a plumber in London?
Availability varies by borough and time of year. For non-urgent repairs, requesting quotes lets you compare prices and dates. For a leak you can't stop, call a plumber who offers emergency call-outs.
Why do my taps keep dripping?
London's hard water wears washers and ceramic cartridges faster than soft water. Replacing the cartridge usually fixes it; if the tap is old, a new tap may be better value.
Who repairs a leak from a shared pipe in my block?
Pipes that serve more than one flat are often the freeholder's responsibility. Check your lease and contact the managing agent, and a plumber can confirm where the leak is coming from.
