How much does it cost to repair a leaking pipe? [October 2025]

How long does it take to fix a leaking pipe?

The cost to fix a leaking pipe can vary depending on the severity of the leak and the pipe’s location, as well as a few other factors.

Most plumbers will charge by the hour, averaging out at about £50 - £95 (inc VAT), depending on where you live. If you’re in London, expect to pay around 20% more than in the rest of the UK.

For a straightforward leak in an exposed pipe, a plumber can usually complete the job within 1 to 2 hours. However, if the leak is behind a wall, under flooring, or caused by corroded or burst pipework, the job may take several hours or even require a follow-up visit.

Here’s a rough breakdown of what you could expect to pay for labour only, whether you live in or outside London. 

How much do the materials cost?

The cost of replacement parts will depend on the type and extent of the damage. Most basic pipe repairs only require inexpensive fittings, but full sections of pipe may need to be replaced in more severe cases. 

If your plumber sources these parts, expect a 20 - 25% markup to cover the time and effort sourcing. Of course, you can choose to purchase these yourself but it's often easier to let your plumber handle it instead. 

What other factors affect the cost of fixing a leaking pipe?

There are often several other factors that can impact the total cost of repairing a leaking pipe, including the extent of the damage, any additional work and when you book. 

1. Whether you need an emergency plumber 

If the leaking pipe is causing serious water damage and flooding, you’ll likely need to call an emergency plumber right away. These kinds of leaks can’t wait until regular working hours because the longer they’re left, the more damage they cause - and the more expensive the repair will be.

Emergency plumbers typically charge a premium for urgent callouts, especially outside of normal working hours. You can expect to pay £150 to £250 per hour, including VAT, for emergency plumbing services - with some providers charging a minimum one-hour rate even if the repair is completed faster. Some plumbers also charge a call-out fee, especially during unsociable hours, which can range from £50 to £100 on top of the hourly rate.

2. Additional work

If the leak has caused cosmetic or structural damage, you might need to budget a bit more for repairs. For example, if a pipe has been dripping into a wall cavity or under the floor, you could end up needing some plastering or painting once the wall’s been opened up. You might also need to replace tiles or flooring, and in some cases, pay for mould remediation if the area’s been damp for a while. These extra costs can vary a lot - from around £100, right up to £1,000 or more - depending on how much damage there is and the quality of materials you go for.

3. Who you book with

Independent plumbers will usually charge lower rates than larger tradesperson companies. You may find some sole traders operate below the VAT threshold, meaning you could end up saving 20% VAT on your service.

While bigger companies often charge more, they usually come with better perks, such as greater slot availability, backup plumbers in cse of sickness on the day, and a dedicated customers service team at hand to help in case anything goes wrong.

What are the signs of a leaking pipe?

Surprisingly, it’s not always easy to spot when you have a leaking pipe. Sometimes it can be as obvious as dripping water sounds or visible puddles, but other times the signs are much more subtle - like a damp patch on a wall, a musty smell, or a sudden spike in your water bill.
 

How can I stop pipes from leaking in the first place? 

Leaks are far less likely when you take proper care of the pipes in your home. Regularly inspecting your pipework, ensuring it’s well-supported, and prepping them for winter are essential. 
 

1. Check your pipework

You should check your pipework every so often, especially in places like under sinks, behind appliances, or in your airing cupboard. Look out for any signs of wear, rust, or limescale around joints and fittings - these can be early signs that something’s not quite right.

2. Ensure pipes have proper support

Over time, vibrations from water flow can loosen poorly secured pipes, especially in older homes. Loose pipe brackets or fittings can lead to strain and eventually leaks - so if you hear banging or rattling (AKA a “water hammer”), it’s worth getting it looked at.

3. Prepare pipes for winter

Cold temperatures during the winter can cause water inside pipes to freeze and expand. This puts pressure on the pipes, leading to cracks or bursts. 

It's a good idea to also insulate any exposed pipework and water tanks in unheated areas like lofts and garages. Make sure to repair any dripping taps straight away too, as even a slow drip can freeze and cause blockages in the pipes. ^[1, 2]

Can I fix a leaking pipe myself?

While it may be possible to repair a minor leak, more serious leaks - especially those involving hidden pipework - are best left to professionals. Incorrect repairs can make the issue worse and lead to water damage or even void your home insurance.

A professional plumber will be able to accurately diagnose the roote cause of the leak and carry out a safe and lasting repair. They’ll also have the right tools and experience to handle more complexed leaks, such as those inside walls or under floors, which are difficult to access and repair properly.
