What Is Water Supply Pipe Insurance?

---

The water supply pipe is an external pipe that connects your home to the main water supply. Problems with this pipe can leave your home without water and it’s, therefore, a good idea to have insurance cover if you are responsible for this section of plumbing.

Does building insurance cover my water supply pipe?

No, not always, and if your building insurance doesn’t provide cover you may wish to consider looking at additional water pipe insurance.

If you own a property and the water supply pipe passes through your grounds or garden,  you will have either sole or joint legal responsibility for that water supply pipe (depending on how many properties are served by the same supply pipe).

If you or you and your neighbours served by the same pipe have no front garden, you may not have any legal responsibility for the water supply pipe – because it doesn’t pass through the land you own.

Building insurance tends to cover water pipes that you have legal responsibility for and therefore if you’re a homeowner you should be able to find a policy which offers you this cover.

Do I need separate water pipe insurance?

Homeowners and landlords can take out this insurance if they feel their building or contents insurance doesn’t offer sufficient cover for the pipes in or on their property – including the water supply pipe.

Sometimes the wording on a building insurance policy indicates that water escapes originating outside the home, which aren’t causing damage to the interior of the home or its contents, will be counted as an exclusion.  This could mean damage to your water supply pipe won’t be covered by your building insurance if it isn’t affecting the interior of your property.

If you have no front garden, live in a block of flats, in council housing, or rent from a private landlord insurance cover aimed at the water supply pipe is neither suitable nor needed.

Can you get burst pipe insurance for your water supply pipe?

Yes, burst pipe insurance for your water supply pipe is widely available in the UK. You can get it as:

• Part of buildings insurance – some policies include water supply pipe cover as standard
• An add-on to buildings insurance – typically £20 to £40 a year for specific water supply pipe cover
• Standalone water supply pipe insurance – usually offered by water companies themselves, around £70 to £90 a year

Before paying for separate cover, check your existing buildings insurance policy. Many UK insurers now include underground pipe cover within the main policy, and paying twice for the same protection is a common waste of money.

Typical claim limits range from £1,000 to £5,000 per incident, which covers most straightforward burst pipe repairs. For larger jobs involving driveway excavation or extensive ground reinstatement, check whether your policy includes those costs or treats them as exclusions.

Do you need mains water supply insurance?

Your mains water supply is dealt with by the company that supplies your water and they have legal responsibility for the pipes leading either up to your water supply pipe or to your property if you have no front garden. 

The water company must deal with any damage to the mains water supply and therefore your insurance does not need to cover the mains supply.  In fact, you are entitled to financial compensation from the water company if you are left without water for more than 48 hours.

What happens if your water supply pipe bursts?

A burst water supply pipe can cause significant damage in minutes. Here’s what to do:

1. Turn off the water at the stopcock. This is usually under the kitchen sink or in a utility room. If you can’t find it, call your water supplier.
2. Turn off the electricity if water is near electrical fittings or sockets.
3. Move valuable items away from affected areas.
4. Take photos and keep receipts for any immediate repairs or accommodation costs.
5. Call your insurer as soon as you’ve made the property safe. Most insurers have 24-hour emergency lines.

Repair costs can range from £300 for a minor leak to £3,000+ if the pipe needs excavating under a driveway. This is why having the right cover matters before something goes wrong.

Who is responsible for the water supply pipe?

Responsibility depends on where along the pipe the problem occurs. Your water company is responsible for the mains pipe up to the boundary of your property – usually the front wall or garden boundary line.

From the property boundary to the stopcock inside your home, the pipe is your responsibility. That means if it bursts, leaks, or blocks on that section, you pay for the repair. For most UK homes this covers a section of pipe 5-15 metres long, depending on how far the house is set back from the street.

You’ll need buildings insurance or a specific water supply pipe add-on to cover your section. Some insurers include it as standard, others charge £20-40 a year extra.

How much does water supply pipe cover cost?

Water supply pipe insurance typically costs £20 to £50 a year as an add-on to your buildings insurance. Some UK insurers include it automatically, others charge a separate premium.

What you get for the money varies:

• Basic cover – around £20-30 a year, covers the cost of finding and repairing a leak.
• Comprehensive cover – £40-60 a year, may also include labour costs, reinstating driveways or gardens after digging, and emergency call-out fees.

Some water companies also offer standalone water pipe cover for around £70-90 a year. Compare this against your existing home insurance before paying for separate cover – you may already be protected.

You might also need

Alongside water supply pipe cover, you may want to consider:

• Buildings insurance – covers the structure of your home and underground pipes within your property boundary.
• Home emergency cover – covers emergency plumber call-outs for burst pipes, leaks, and boiler breakdowns.
