Incident Update - 22:00 20/11/2025

We are currently transferring water around the network as the system recovers from the Hampton outage. In some areas we are working to manage airlocks in the system which may be impacting supplies.

Unfortunately, water may not be running through your tap as usual or you may be experiencing low pressure. We apologise if this is having an impact on customers. We are working throughout the night to resolve this issue and return supply tomorrow morning. Our lorry tankers are also supporting the network by pumping water into the system.

The following postcode areas may still have no water or low pressure:
EN1, EN2, EN3, EN7, EN8, N3, N4, N6, N7, N8, N10, N11, N13, N14, N19, N21, N22, NW1, NW2, NW3, NW4, NW5, NW6, NW7, NW8, NW9, NW10, NW11

Residents in high-rise buildings who are still facing low pressure should get in touch with their building’s managing agent, as they can reset internal pumps to help improve flow.

If your water is flowing but looks a little different (for example, slightly discoloured), please see our advice on after an incident.

If you or someone you know needs a little extra support, our free Priority Services Register can help us to understand your situation so we can take it into account as best we can.

We’ll share another update by 08:30 tomorrow morning. Thank you for your patience and understanding while we continue working to fully restore your water supply.

Our Hampton Water Treatment Works continues to increase the amount of water being produced for our network as our teams carefully monitor and gradually raise the level of water being fed into the pipes.
