London's housing stock keeps plumbers busy in ways other cities don't see. A Victorian terrace in Walthamstow or Brixton might still have lead supply pipes and a cramped, awkward airing cupboard. A 1930s semi in Bromley is likely to have copper throughout and a boiler that's been patched for a decade. Then there are the mansion blocks of Kensington, the ex-council flats in Peckham and the new-builds along the Thames, each with different pipework, different access problems and different rules from the freeholder. Hard water is the other constant. Most of London sits on chalk and limestone, so limescale chokes boilers, shower valves and taps faster than many people expect.

Here's how the businesses on this page were chosen. We draw them from third-party business listings and rank them by public review rating and review count, with a small lift for those showing a working website and phone number. We then read each homepage to confirm plumbing work is what the business primarily offers, which keeps unrelated trades off the page. Listings flagged as permanently closed are removed automatically. Where you see a Trust Verified badge, that business has additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page lists every check. If a business doesn't carry the badge, we haven't independently verified it, so those checks are down to you before you book.

A few habits will save you money and grief. Ask for a written quote that splits labour, parts and call-out fees, and get two or three so you can spot an outlier. If the job involves a boiler, gas hob or any gas appliance, ask for the engineer's Gas Safe number and check it on the Gas Safe Register yourself. Ask about public liability insurance and request a copy of the certificate. Find out where your stopcock is before anyone arrives, because a plumber will want to isolate the water straight away. For bigger work, such as a new bathroom or a full heating system, ask what's covered by a guarantee, who clears the waste, and whether the price includes making good tiles and plaster.

Frequently Asked Questions

How much does a plumber cost in London?
Expect to pay roughly £60 to £110 an hour for a plumber in London, with some firms charging a flat call-out fee of £60 to £120 that may include the first hour. Emergency work out of hours, at weekends or overnight can run to £150 to £250 an hour. Small jobs like replacing a tap or fixing a leaking valve typically come in at £80 to £200. A new combi boiler installation usually costs £2,200 to £4,500 depending on the model and how much pipework needs altering. Central and west London tend to be pricier than the outer boroughs, and parking and congestion charges often get added. Getting two or three quotes is normal and sensible.
Do I need a Gas Safe registered plumber?
Only for gas work. Fitting, servicing or repairing a boiler, gas hob, gas fire or any gas pipework legally requires an engineer on the Gas Safe Register. A plumber who fixes taps, toilets, radiators or waste pipes doesn't need it for that work, though many plumbers hold it as well. Ask to see their Gas Safe ID card, check the back for the types of work they're qualified to do, and look them up on the official register using their licence number.
What should I do if I have a burst pipe or major leak?
Turn off the water at the stopcock straight away. It's usually under the kitchen sink, but in older London flats it can be in a hallway cupboard or the meter box outside. Open the cold taps to drain the system, switch off the immersion heater and boiler if you have one, and mop up what you can. If water has got near electrics, turn the power off at the consumer unit. Then call a plumber who offers genuine emergency call-outs. If you're in a flat, tell the neighbours below and your freeholder or managing agent.
How long does a boiler replacement take?
A straightforward like-for-like combi swap usually takes one day, often six to eight hours. Moving the boiler to a different wall, converting from a system with a hot water cylinder to a combi, or fitting new flues can stretch to two or three days. In a typical Victorian terrace, expect extra time for routing a condensate pipe and sorting the flue position. Ask when the heating and hot water will be off, and whether a powerflush or magnetic filter is included in the quote.
Can a plumber fix low water pressure in my London flat?
Often, yes, but the cause varies. In older buildings it can be furred-up pipes, a partially closed stopcock or a failing pressure-reducing valve. In flats supplied from a loft tank, gravity-fed pressure is naturally low, and a shower pump or a switch to a mains-fed system may be the answer. Limescale on shower heads and aerators is common in hard-water areas and easy to fix. Ask the plumber to measure the flow rate and mains pressure before recommending anything costly.
How can I check a plumber is trustworthy before I hire them?
Start with the basics. Read recent Google reviews and look for detail, not just star ratings. Ask for their full business name, address and landline, and check the company on Companies House if they trade as a limited company. Request proof of public liability insurance, ideally £1 million or more. For gas work, verify their Gas Safe number on the official register. Ask whether they hold relevant trade accreditation for the work you want done, and what guarantee they give on workmanship. Get the quote in writing and be wary of anyone demanding a large cash payment up front. Remember that only businesses with a Trust Verified badge have passed our own checks. Everyone else on this page needs checking by you.
