How much does a plumber cost in the UK?
Plumbing costs in the UK vary depending on the type of job, your location, and whether you need an emergency response. Here is what you can expect to pay for the most common plumbing jobs.
Typical plumbing costs (2025–2026)
| Job type | Typical price range |
|---|---|
| Call-out / inspection fee | £60 – £120 |
| Leak detection (pipe or under-floor) | £150 – £350 |
| Burst pipe repair | £100 – £350 |
| Drain unblocking | £80 – £200 |
| Toilet cistern repair | £60 – £150 |
| Tap washer replacement (per tap) | £40 – £90 |
| Boiler replacement — see separate guide | £1,800 – £4,500 |
| Bathroom renovation (full replumb) | £3,000 – £9,000+ |
| Unvented cylinder installation | £1,200 – £2,500 |
What affects the price?
- Emergency vs planned. After-hours or weekend call-outs typically add £40–£100 to the base rate.
- Location. London and the South East are generally 20–30% higher than the rest of the country.
- Access difficulty. Pipes boxed in, under floors, or in tight spaces take longer and cost more.
- Parts and materials. Branded cylinders, copper pipe fittings, and premium fixtures cost more than generic alternatives.
- VAT registration. Not every plumber charges VAT — sole traders below the VAT registration threshold (£90,000 turnover as of 2024/25) don't have to register, so a lower-looking quote may simply be VAT-free rather than cheaper labour. Ask whether the figure is VAT-inclusive.
Tips for getting a fair price
- Get at least three quotes before accepting. TruePro sends your request to every matching verified plumber in your area, and each quote shows their trust score based on completion rate, cancellations, and case history — so you can compare on more than price.
- Ask for a written, itemised quote — not just a verbal estimate. A proper quote breaks down parts, labour, and VAT separately.
- Check that the plumber carries public liability insurance. This protects you if anything goes wrong. TruePro shows an "Insured" badge on the plumber's profile and quote once we've verified their cover.
- Avoid paying cash upfront. TruePro's payment protection holds your payment securely until you confirm the work is done.
What to watch out for
- "Come and see" quotes. A plumber who refuses to give any price indication before arrival may upsell on site.
- Cash-only payment. Legitimate plumbers provide invoices. Cash-only jobs have no paper trail if something goes wrong.
- Gas work needs Gas Safe registration. Anyone can call themselves a plumber, but it is a legal requirement that any work on a gas appliance, boiler, or gas pipework is carried out by an engineer on the Gas Safe Register — never let anyone off the register touch gas. Every TruePro plumber's Gas Safe registration is checked before we show a verified badge on their profile.
