Thames Water, who supply around half of borough residents, will begin rolling out the meters in Dudden Hill and Willesden Green.

From last month, residents have been recieving the new technology giving them access to their water use data.

Customers can access the data online or over the phone and assess how efficient their home is along with tracking how simple water-saving efforts - such as four-minute showers or switching the taps off whilebrushing your teeth - can reduce their bills.

In Brent, Thames Water supplies homes in Dudden Hill, Willesden Green, Mapesbury, Brondesbury Park, Kilburn, Queens Park, Dollis Hill, Welsh Harp, Kensal Green, Stonebridge and Harlesden.

Just under a third of those homes covered by Thames Water in the borough already have a water meter and they aim to fit approximately 30,000 more smart meters in Brent over the next few years.

Danny Leamon, Thames Water’s head of metering, said: “Our smart metering programme has already saved millions of litres in other London boroughs and we’ll be doing the same in Brent, starting in Dudden Hill and Willesden Green wards.

“This is good news for customers, who will have access to new technology to help them reduce their water usage and bills, and great news for the environment, as there are increasing pressures on our water sources.

“Our forecasts show that if we continue as we are, by 2020 there will be a shortfall of 133 million litres of water per day - that is the amount needed by 850,000 people.

“We are in touch with customers to let them know what’s happening and we’ll also have a team out and about to answer any questions in person.”

Thames Water will be offering free home visits from a team who can check how water efficient a house is and install water-saving gadgets which they claim could eventually save a family of four as much as £190 per year on their water and energy bills.

Since the launch of their metering programme in 2015, Thames Water has delivered more than 45,000 Smarter Home Visits, saving around 2.5 million litres every day - the equivalent water supply for more than 6,000 homes.
