It said that the problem had a knock-on effect at Hampton Water Treatment Works, affecting a large number of customers.

In their latest update, Thames Water said: "The power supply is now back on at Ashford Water Treatment Works and supplies should be starting to return across the area. "

It added: "We're working hard to get things back to normal as soon as possible, but it's likely to take some time for the supply system to refill and for water to fully return to the whole area."
