Slough's housing mix throws up a fair range of plumbing work, from the 1930s semis around Cippenham with their original cast iron soil pipes to the newer developments near the Bath Road and Salt Hill with combi boilers and pressurised systems. Older properties in areas like Chalvey often still have lead or galvanised supply pipes that need replacing, while flats near the town centre tend to bring more common issues like blocked shared drains or airing cupboard cylinder faults. A plumber who knows the area will recognise these patterns quickly, whether that's hard water scaling from the local supply or the type of stopcock fitted in a 1960s council-built terrace.

The businesses listed here are pulled from public business listings and ranked by their review rating and how many reviews they've built up, with a modest boost given to those showing a working website and contactable phone number. We check each business's homepage ourselves to confirm plumbing is genuinely their main line of work, which is how we filter out general builders or heating engineers who only do the odd tap fitting. Any listing flagged as permanently closed gets removed automatically, so what you see should reflect businesses still trading. Where a business carries our Trust Verified badge, it means they've gone through our fuller check covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company details, and you can read exactly what that involves on our How We Verify page. For any business without that badge, those checks haven't been done by us, so it's worth doing them yourself before booking.

Before agreeing to any work, ask to see a Gas Safe registration card if the job involves a boiler or gas appliance, and don't be shy about asking for the registration number so you can check it yourself. For general plumbing, ask whether they carry public liability insurance and what guarantee they offer on parts and labour, typically six months to two years depending on the job. Get two or three written quotes for anything beyond a simple tap washer or minor leak, since prices for jobs like a full bathroom re-plumb can vary by hundreds of pounds between tradespeople. It's also worth asking how they handle waste removal, particularly for bathroom refits, as some quotes include skip hire and others don't.
How We Select & Rate The Best Plumbers in Slough

Rankings are based on review rating and review count taken from public business listings, with a small lift given to businesses that show a working website and phone number. We read each business's homepage to confirm plumbing work is what they primarily do, which keeps unrelated trades off this page. Listings flagged as permanently closed are removed automatically. Businesses carrying our Trust Verified badge have additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information; see our How We Verify page for full details. Other businesses here haven't been independently verified by us, and their inclusion isn't an endorsement. Always do your own checks before hiring.

Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

Frequently Asked Questions

How much does a plumber cost in Slough?
A basic call-out for something like a dripping tap or running toilet typically runs £60 to £120 for the first hour, including the visit. Bigger jobs cost more: a full bathroom re-plumb might be £1,500 to £4,000 depending on pipework changes, while fitting a new combi boiler generally sits between £2,000 and £3,500 including parts. Emergency call-outs, especially evenings or weekends, often carry a premium of £20 to £50 on top. Prices vary between tradespeople, so getting two or three quotes for anything beyond a minor repair is standard practice and worth doing.
Do I need a Gas Safe registered plumber for boiler work in Slough?
Yes, any work on a gas boiler, gas fire, or gas pipework legally needs a Gas Safe registered engineer, not just a general plumber. Ask to see their Gas Safe ID card before work starts and check the registration number on the Gas Safe Register website if you're unsure. General plumbing repairs like fixing leaks or replacing taps don't require this, but anything touching the gas supply does.
How quickly can a plumber in Slough deal with an emergency leak?
Most local plumbers offering emergency call-outs aim to reach you within one to three hours, though this depends on how busy they are and your exact postcode. Areas like Langley or Britwell might see slightly longer waits during peak times such as winter mornings when burst pipes are common. If a leak is serious, turn off the water at the stopcock first, usually found under the kitchen sink or near the front of the property, and mention the urgency clearly when you call.
What's the difference between a plumber and a heating engineer?
A plumber typically handles water systems: leaks, blocked pipes, bathroom fittings, and drainage. A heating engineer specialises in boilers, radiators, and central heating systems, and needs Gas Safe registration for gas appliances. Many tradespeople in Slough do both, but if your job is specifically boiler-related, check the business's homepage or ask directly whether they're Gas Safe registered rather than assuming.
Should I get a written quote before plumbing work starts?
Yes, always ask for a written quote rather than relying on a verbal estimate, particularly for jobs over a couple of hundred pounds. A proper quote should break down labour, parts, and any extras like waste disposal or skip hire. This protects you if the final bill differs from what was discussed and gives you something to compare against other quotes.
How do I choose between plumbers listed on this page?
Start by reading a handful of recent reviews rather than just the overall star rating, since that tells you how they've handled recent jobs. Check whether they're Gas Safe registered if your job involves a boiler, and ask to see proof rather than taking their word for it. Confirm they carry public liability insurance, ask what guarantee they offer on completed work, and get at least two quotes for anything beyond a small repair. If a business carries our Trust Verified badge, that means we've already checked qualifications, insurance, trading history, and company details, but for anyone without it, doing these checks yourself before booking is worth the ten minutes it takes.
