Burst pipe insurance claims: what to do first

A burst pipe is stressful enough without a claim going wrong. Most problems with burst pipe claims come from what happens in the first hour: no photos, no written cause, or a repair that hides the evidence. This guide sets out the steps for a Bristol home, including the help Bristol Water offers when the burst is underground.

First, stop the damage

Insurers expect you to limit the damage. Do these first:

1. Turn off the inside stop tap. In older Bristol terraces it is often under the kitchen sink, under the front room floor, or in the cellar.
2. If water is near sockets, lights or the consumer unit, turn off the electricity at the main switch if it is safe to reach. Do not touch electrics with wet hands.
3. Open the cold taps to drain the system.
4. If the burst is on the hot side, turn off the boiler or immersion heater.
5. Move valuables and furniture away from the water.
6. If you live in a flat, warn the neighbours below. In Clifton and Redland conversions, a burst on an upper floor often reaches two flats before anyone notices.

Our guide to a plumbing emergency covers this first ten minutes in more detail.

Second, record everything

Before you mop up or let anyone start ripping out:

• take photos and video of the burst pipe, the water, the ceilings, floors and damaged items
• note the date and time you found it
• keep any damaged parts the plumber removes, such as a split fitting
• write down what was happening, for example a freeze the night before

Ask your plumber for a short written report. It should say where the burst was, what failed, the likely cause, and what was done. Insurers often ask whether damage came from a sudden burst or a slow leak over months. Slow leaks and wear and tear are commonly excluded, so the cause matters.

Third, call your insurer

Phone early, even before the repair is finished. Ask:

• are you covered for escape of water, and what is the excess?
• do you have trace and access cover? This pays to find a hidden leak and make good the floor or wall opened to reach it.
• do they want to send their own loss adjuster or drying company?
• can you go ahead with an emergency repair now?
• is there alternative accommodation cover if the home is unusable?

Escape of water and trace and access are separate in many policies. The first covers the damage the water causes. The second covers the cost of locating the leak. The pipe repair itself may not be covered at all.

When the burst is outside the house

Underground bursts are common in Bristol cold snaps and in older homes with lead supply pipes. Responsibility depends on where the pipe is. Ofwat explains that the supply pipe from the boundary into the house belongs to the property owner. The water main and the pipe up to the boundary stop tap belong to the water company.

Where the burst is	Who fixes it	Help available
Under the street or pavement before the boundary stop tap	Bristol Water	Report it to Bristol Water
Between the boundary stop tap and your house	You	Bristol Water leak help, possibly insurance
Inside your home	You	Insurance under escape of water
A supply pipe shared with neighbours	All owners on that pipe	Split costs, Bristol Water advice

Bristol Water’s help with leaks page lists what it offers on underground private pipes:

• up to half an hour of free leak detection with advice
• an automatic £100 subsidy for homeowners once it confirms a leak has been repaired
• a £250 subsidy if you replace the leaking supply pipe within 21 days
• a leakage allowance on metered bills if the repair is done within 21 days

Keep receipts and invoices, as Bristol Water asks for proof. It also suggests checking your household insurance, as the repair might be covered.

A BBC Bristol report in August 2026 showed how costly this can get. Residents in Clevedon faced bills of around £5,000 each for a leaking private supply pipe shared between homes. If you share a supply, talk to your neighbours early.

Choosing the plumber

You do not have to use the insurer’s plumber, but check your policy. Some only pay set rates. Whoever you use, ask for an itemised invoice and the written report. For supply pipe work, Bristol Water points customers to the WaterSafe directory of approved plumbers.

Our burst pipe repair page explains what a visit involves: making safe, finding the exact failure, repairing or replacing the section, and testing it under pressure. In a Victorian terrace in Bedminster, that often means lifting floorboards in the front room where the old supply runs.

After the repair

• Let floors and walls dry fully before you redecorate. Insurers may send a drying company with moisture meters.
• Check the ceiling below for sagging plaster, which can fall after a soak.
• If you are on a meter, apply for Bristol Water’s leakage allowance.
• Lag any pipe that froze, so it does not happen again. Our guide to frozen pipes has a checklist.
