TL;DR — Leaking Pipe Repair Cost At A Glance
Most leaking pipe repairs cost £80–£250 outside London and £120–£350 in London, with the average simple job around £100–£150.
- Hidden leaks behind walls or under floors, and emergency call-outs, push costs to £300+ because of tracing, access and out-of-hours premiums.
- The parts are cheap — joints, seals and connectors are £2–£30 — so labour, access and urgency drive the price.
- Cost drivers are the location and severity of the leak, whether the pipe is exposed or concealed, emergency timing and your area.
- A minor leak in an exposed pipe is the cheapest fix; a major leak behind a wall or under a floor is the most expensive.
- Acting fast limits water damage — a small leak left alone can lead to rot, damp and far bigger bills.

How Much Does Leaking Pipe Repair Cost In 2026?
Fixing a leaking pipe in the UK typically costs £80–£250, rising to £120–£350 in London and the South East. A minor leak in an easy-to-reach exposed pipe sits at the lower end, while a hidden leak behind a wall or under a floor — where the plumber has to trace the source and open up the structure — runs to £300 or more. Emergency and out-of-hours call-outs carry a further premium on top.
Two things decide the price: where the leak is, and how bad it is. An exposed pipe under a sink is quick to reach and quick to fix. A leak behind tiling, inside a stud wall or beneath a floor first has to be located, then accessed, then repaired, then made good — several stages, sometimes across more than one visit. The minimum call-out (around £60–£120 for the first hour) sets the floor, and urgency lifts it: a burst pipe at the weekend costs considerably more than a booked daytime repair.
Here is what you can expect to pay by the location and severity of the leak:
| Location and severity | Rest of UK | London & South East |
|---|---|---|
| Minor leak, exposed pipe | £100 – £130 | £120 – £150 |
| Major leak, exposed pipe | £130 – £160 | £150 – £200 |
| Minor leak under sink or basin | £100 – £140 | £130 – £170 |
| Major leak under sink or basin | £140 – £180 | £170 – £220 |
| Minor leak behind wall or under floor | £150 – £200 | £180 – £240 |
| Major leak behind wall or under floor | £200 – £250+ | £240 – £300+ |
Figures include VAT and reflect 2026 market rates. Hidden leaks that need tracing and access, and emergency call-outs, cost more — get help here.
Leaking Pipe Repair Cost Breakdown: Parts Vs Labour
The parts to fix a leaking pipe are inexpensive. Almost all of the cost is labour, access and — for urgent jobs — the emergency premium.
| Part | Typical price (inc VAT) |
|---|---|
| Compression joint or seal | £3 – £10 |
| Push-fit connector | £2 – £10 |
| Copper pipe (per metre) | £5 – £15 |
| Isolation valve | £5 – £15 |
| Flexible hose replacement | £10 – £30 |
| Labour / call-out (first hour) | £60 – £120 |
If a quote is heavily weighted towards materials for a simple exposed-pipe fix, ask for a breakdown. Where the cost genuinely climbs is in the finding and reaching of a hidden leak: lifting floorboards, cutting into plasterboard or removing tiles, then making good afterwards. Those stages, not the fitting itself, are what turn a £120 job into a £300+ one.
What Affects The Cost Of Fixing A Leaking Pipe?
1. The Location Of The Leak
An exposed pipe is the cheapest to fix. A leak under a sink is slightly more. A leak behind a wall or under a floor is the most expensive, because it has to be traced and the structure opened up and repaired afterwards.
2. The Severity Of The Leak
A minor weep from a joint is a quick fix. A major leak or a burst pipe may mean cutting out and replacing a section of pipe, and dealing with water that has already spread.
3. Exposed Vs Concealed Pipework
Concealed pipes need leak detection and access work. This can add hours and, in some cases, specialist equipment to pinpoint the source before any repair begins.
4. Emergency And Out-Of-Hours Timing
A booked daytime repair is the cheapest. Same-day, evening, weekend and bank-holiday call-outs carry a premium — often 1.5 to 2 times the standard rate plus a call-out fee — because a leak rarely waits.
5. Your Location
London and the South East run roughly 15–30% higher than the North of England, Wales and Scotland, reflecting higher labour and travel costs.
6. Making Good And Water Damage
Repairing the pipe is one cost; putting right the plasterboard, tiling, flooring or ceiling afterwards is another. Significant water damage can bring in other trades.
What's Included — And What's Not
Quotes vary in what they cover, so it pays to check line by line before booking. Here's how a leaking pipe repair usually splits:
| Typically included in a leaking pipe repair | Usually charged separately |
|---|---|
| Locating the leak (for accessible pipework) | Specialist leak detection for hidden leaks |
| Isolating the water supply | Opening up and making good walls, floors or ceilings |
| Repairing or replacing the affected section of pipe or joint | Replacing longer runs of damaged pipe |
| Testing for leaks once complete | Out-of-hours or emergency premiums |
| Small consumables such as joints, seals and PTFE tape | Repairing water damage or drying out affected areas |
Ask for the scope in writing, and for a hidden leak, ask how detection and making good are priced.
Can You Fix A Leaking Pipe Yourself?
For a minor leak on an accessible pipe — a weeping compression joint under the sink, for instance — a confident DIYer can tighten the fitting, replace a washer, or fit a push-fit repair coupler after isolating the water. Doing so can stop a small leak quickly and cheaply. As a first step for any leak, know where your stopcock is and turn the water off to limit damage.
Call a plumber promptly when the leak is major or a burst, when it is behind a wall, under a floor or in the ceiling, when you cannot find the source, or when it involves the mains supply. Hidden leaks in particular need proper tracing — guessing means opening up the wrong section — and getting a concealed repair wrong risks damp, rot and a much larger bill later. For anything urgent, an emergency plumber is the right call.

How To Save Money On Leaking Pipe Repair
Act fast and turn off the stopcock — limiting water damage is the biggest saving of all.
- Book in normal hours where the leak is contained and not urgent, to avoid emergency premiums.
- Clear access to the affected pipe before the plumber arrives, so paid time goes on the repair.
- Bundle nearby jobs — a dripping tap repair or a slow drain — into the same visit.
- Fit isolation valves during any plumbing work so future leaks can be isolated without draining the system.
- Maintain your pipework — lag pipes against frost and address damp patches early to prevent leaks in the first place.
How To Hire A Good Plumber
Ask for recommendations, check reviews, and get a written quote or a clear explanation of how an emergency job is charged (call-out plus hourly, and any out-of-hours rate). Confirm the plumber is insured, and for a hidden leak, ask whether they carry leak-detection equipment so the source is found without unnecessary damage.
