Many homes have been left with little to no water after a pipe burst overnight – and repairs “could take some time”.

Thames Water has confirmed it is aware of an incident which is affecting its customers across parts of north west London.

The water company says a pipe has burst where the A1 and A41 meet by Fiveways Corner near Hendon.

Photos taken at the scene on the A41 show a huge puddle of water across the carriageway with firefighters on-site. An underpass has also flooded.

The A41 is shut southbound between Fiveways Corner and Greyhound Lane and traffic is very heavy in the area. The A41 has reopened northbound.

People woke up this morning and reported they had no running water from their taps – Thames Water says properties within the NW4, NW5, and NW11 postcodes are affected, which include Hendon, Mill Hill, and Golders Green.

The company has warned the leaky pipe is “large” and therefore a repair “will take some time”.

Work to fix the issue has also been delayed because a tree needs to be removed after being uprooted.

Some homes may have seen a return of their supply but water pressure is still likely to be lower than usual. Some might still not have any water at all.

Thames Water says it has several tankers in the area that will feed water directly into its network to keep taps running for as many customers as possible.

Its latest update at 11.50am (December 11) confirmed engineers are working to shut off the damaged section of pipe, but the tree is delaying progress.

Bottled water will be delivered to customers who need extra care from around 12.30pm onwards and a bottled water station is also being set up in the area, with the location to be confirmed.

Customers with access to water in the affected areas should use it sparingly for now.

Thames Water added on its website: “We’re really sorry if you’ve woken up this morning to find you have low pressure or no water. It’s due to a large burst pipe in Westside, NW4, which happened just after 3am.

“This is one of our biggest pipes in the area and could take some time to repair. We’re really sorry if this has disrupted your day.

“We’re grateful for your understanding and patience while we work to fix this.”

The London Fire Brigade tweeted at around 7am: “Firefighters are assisting @thameswater with a burst water main in #Hendon. The A41 is closed in both directions at the moment which is causing traffic disruption in the local area.”
