Why is there no water in my area? Thames Water low pressure issues explained and list of postcodes affected

Thousands of homes in west and south-west London have been left without running water or with very low pressure due to a power supply issue.

Thames Water said the problem has been caused by a power supply issue that is affecting its Ashford and Hampton water treatment works.

Which postcodes are affected?

Brixton, Clapham, Lambeth, Chiswick, Richmond, Putney, Wandsworth and Twickenham are among the south-west London areas experiencing water problems.

In west London, areas including Westminster, Marylebone, Paddington, Hammersmith, Shepherd’s Bush and Ealing have been hit.

Thames Water said the following postcodes are affected: SW4, SW8, SW9, SW13, SW14, SW15, SW18, SW19, TW1, TW2, TW3, TW4, TW5, TW7, TW8, TW9, TW10, TW11, TW12, TW13, TW14, TW17, W1H, W1M, W1N, W2, W3, W4, W6, W7, W10, W12, W13, and W14.

Earlier in the day Thames Water said the following postcodes were also experiencing problems, but they have since been removed from the list: CR4, E5, E8, EC1V, KT1, KT2, KT3, KT8, HA0, N1, N15, N16, N17, NW1, NW2, NW10, SE1, SE11, SE16, SE17, UB1, UB2, UB6, W1H, W1H, W1M, W1N.

Munira Wilson, the Lib Dem MP for Twickenham in south-west London, said the problem has forced a number of schools in her constituency to close, urging Thames Water to “sort this soon”.

When will the problem be fixed?

Thames Water has not yet given a timeframe for the issue being fixed. The provider said in a statement: “We’re working hard to fix the issue and to get things back to normal.

“We’ll provide further updates here as soon as we have more information.”
