How Much Does a Plumber Cost in London? (2025 Price Guide)

Average plumber costs in London

London plumbers typically charge a callout fee of £60–£100, plus an hourly rate of £80–£150 depending on the company, location, and time of day. For out-of-hours and emergency work, those rates can rise to £150–£250 per hour.

Most straightforward jobs — a dripping tap, a leaking pipe under a sink, a running toilet — take between 30 minutes and an hour once the plumber is on site. You should budget for at least one hour of labour even for simple fixes, as most companies apply a minimum charge.

What affects the price?

Several factors push plumbing costs up or down in London:

• Emergency vs. scheduled — emergency callouts can cost 2–3× the standard rate
• Time of day — evening, weekend, and bank holiday work carries a premium
• Type of work — a new bathroom installation is priced very differently from a tap washer replacement
• Access difficulty — pipes hidden behind tiling or in awkward spaces take longer
• Parts required — always ask whether the quote includes materials or just labour

Common jobs and typical costs

Here is a rough guide to what specific plumbing jobs cost across London:

• Dripping tap repair: £70–£150 (including callout)
• Leaking pipe repair: £100–£250
• Toilet cistern repair: £100–£200
• Outside tap installation: £150–£300
• Full bathroom installation: £2,000–£5,000+ (labour only)
• Emergency burst pipe: £200–£500+

How to get the best value

The best way to avoid being overcharged is to book a scheduled visit rather than an emergency callout whenever the job can wait. Always ask for a written quote before work begins, and check whether VAT and parts are included.

Choosing a local, multi-trade company often works out cheaper than specialist plumbing firms — especially for smaller jobs where the callout fee represents a large proportion of the total cost.
