Homes and schools across west and south-west London are suffering low pressure or no water at all this morning due to a power issue.

Thames Water apologised in a statement for the disruption, and said it is “working hard to fix the issue”.

The outage is due to a power supply issue at its Ashford and Hampton water treatment works in west London.

Households in Putney, Twickenham, Clapham, Battersea and Wembley are among those affected, with several local councils, including Richmond and Hounslow, reporting issues in their boroughs.

The full list of postcodes impacted is: SW4, SW8, SW9, SW13, SW14, SW15, SW18, SW19, TW1, TW3, TW2, TW4, TW5, TW7, TW8, TW9, TW10, TW11, TW12, TW13, TW14, TW17, W1H, W1H, W1M, W1N, W2, W3, W4, W6, W7, W10, W12, W13, W14.

Liberal Democrat MP for Twickenham, Munira Wilson, said she is also hearing of some schools locally which are not opening due to a lack of water.

Ms Wilson posted on X: “Our supply in Whitton also stopped ths morning. @thameswater need to sort this soon!”

A Thames Water spokesperson said: “We’re really sorry to customers in west London who are experiencing low pressure or no water.

“We’re working hard to fix the issue, which was caused by a power supply problem which has affected our water treatment works in west London. We’re now back in power and expect water supply to return across the day.

“Getting water supplies back on is our top priority and while our team work on this we’re identifying everyone in the affected area who has pre-registered with us as having special requirements, such as being medically reliant on water, so we can get in touch and make sure we give them the help and support they need.”
