If you can't see an incident in your area, make the following checks:

2. Try your cold kitchen tap

The main water supply normally enters your home in the cold kitchen or utility room tap.

If water comes out of this tap but not elsewhere (such as your shower or bathroom tap), the problem is with your internal plumbing. You may find our list of approved plumbers useful.

3. Check your stop valves are open

Your inside stop valve needs to be fully open. It’s usually located under the kitchen sink, in the airing cupboard or under the floorboards by the front door. If the valve is closed, turn it anti-clockwise to ensure that it is fully open.

If you're unsure on how to find and use your inside stopvalve, watch our helpful video and read our tips.

Your outside stop valve also needs to be fully open. Some properties share their water supply with their neighbours so check with your neighbours to see if they have recently used the outside stop valve.

If you're unable to use or locate the outside stop valve, find out by watching our useful video and reading our tips.

4. Check for frozen pipes

The cold weather can freeze your pipes, making them more likely to expand and burst.

Check visible pipes for damage. If you find a pipe which is frozen, take a look at our useful video for tips on how to treat them.

5. Check with your neighbours

If possible, check if your immediate neighbours have the same problem.

If there is no issue with their supply, the problem is with your internal plumbing. You may find our list of approved plumbers useful.

If you live in a block of flats, check with the building maintenance, your local authority, or the managing agent of the building for any known internal issues.
