Why do I have low pressure?
If you’ve noticed sudden low pressure:
There could be a few reasons for this, a burst main for example that is causing a sudden dip in your pressure or flow. You will need to carry out a few checks:
- Check if the low pressure is only affecting your hot water, this would indicate an internal plumbing problem and you’ll need to contact a plumber. Approved plumbers can be found through WaterSafe or on the Water Industry Approved Plumber Scheme WIAPS.
- Turn your internal stop tap on and off 3 times while the cold kitchen tap is open. You should also check that your external stop tap is open.
- Check if your neighbours have the same problem, if not it is likely that it is an internal plumbing problem.
- Have a look at our In your area site to find out if there’s any work causing this.
If it still remains low after carrying out the 4 checks, please call our Services Helpline on 0344 346 2020 to report this.

- The height of your house in relation to the reservoir
- A smaller or older supply pipe
- A shared supply pipe
- A time of day with higher demand
- Longer internal pipework
