What a plumber does
A plumber handles the water side of a home: leaking taps and pipes, toilets that will not flush or stop running, blocked sinks, new radiators and the plumbing behind a kitchen or bathroom. In Harrow most plumbing jobs are small and urgent, so the useful questions are whether they can come today, what they charge to turn up, and whether the price is fixed or hourly.

Frequently asked questions
How do I find an emergency plumber in Harrow?
Pick a plumber below and send a quote request. On the last step you can mark the job as an emergency, so the business sees at once that it cannot wait. We do not promise call-out times, so if water is coming through a ceiling or near electrics, turn off the stopcock first. Emergency and out of hours visits usually cost more than a booked one, so ask for the price before the plumber sets off.
What should I do if a pipe freezes or bursts?
Turn off the water at the stopcock straight away. For a frozen pipe with no leak, thaw it slowly with a hot water bottle or a hairdryer on low, working from the tap end, never with a naked flame. For a burst, open the cold taps to drain the system, switch off the boiler, and keep water away from electrics until a plumber has repaired it.
Do I need a plumber or a gas engineer?
A plumber deals with water, waste and heating pipework. Anything involving gas, including a boiler, a gas hob or a gas fire, must be done by an engineer on the Gas Safe Register. Many businesses are both, so check the listing or ask.
What should I do about a leak before the plumber arrives?
Turn off the water at the stopcock, usually under the kitchen sink or where the mains pipe enters the house, and switch off the boiler if the leak is near it. Put a container under the drip and move anything electrical away from the water.
Should I ask for a fixed price or an hourly rate?
For a clear job, such as replacing a tap or a toilet cistern, ask for a fixed price including parts. For fault finding an hourly rate is normal, but ask how the first hour is charged and whether there is a call-out fee.
How do I get a quote from plumbers in Harrow?
Pick a listing on this page and send a quote request saying what needs doing and when suits you. The business comes back to you with a price and a time. It is free to ask, and no payment is taken online.
Are the plumbers on this page vetted?
Not yet. Listings marked Claimed have been claimed by the business and are kept up to date by them; the rest come from public records such as Companies House and Google and are marked as not yet claimed. Every listing shows its real Google rating and review count where one exists. We do not check registers or insurance yet, so ask for a Gas Safe or NICEIC/NAPIT number and check it yourself.
What should I check before I hire a plumber?
Ask for a written quote and what it includes, who will do the work, whether they are insured, and any registration the trade needs, such as Gas Safe for gas work or a Part P scheme for electrics. Never pay the full amount up front.
Prices and availability are confirmed by each business. No payment is taken online, you pay the tradesperson directly.
