Check if you need a new water connection
A new water connection is a supply pipe that connects your property to the water main. It carries water from the main to your taps.
When you would need a new water connection
You would need to apply for a new water connection if you’re building a:
- Extension (especially if you’re adding a new bathroom)
- New house
- Block of flats
- Commercial unit
- Industrial site
You may also need a new water connection if there are no issues with your plumbing but you’re still not getting enough water. Our step-by-step guide goes through how to troubleshoot no water or low pressure.

What to check for before applying
Before applying for a new water connection, we recommend you check:
Who supplies your water
If we aren’t your supplier, we won’t be able to help with the new water connection.
You can check who supplies your water on Water UK’s website.
If you're on a shared connection
You could be on a shared connection if you don’t get enough water at peak times. Older terraced properties are also likely to have a shared water supply.
A new water connection can separate your clean water from your neighbour's.
