We are working to restore gas supplies after a Thames Water main burst and water got into the local gas network in the TW10 area of Richmond Hill on Sunday evening, 20 July 2025. We are currently assessing the extent of the area affected. We will need to remove the water from our gas pipes, before we can restore gas supplies to each street and property.
Kane McLoughlin, Head of Operational Delivery for Cadent’s North London network, said: Cadent were made aware of a loss of gas in Richmond Hill area TW10 late last night (20/07/25). Our engineers have been on site since investigating the cause.
We have found that a burst water pipe damaged our gas pipe and water has entered our gas network. Thames Water are currently working on their water main, and we have completed a temporary repair on our gas pipe, to ensure no more water can enter our network. A number of customers have contacted us to let us know that they are affected, but at this stage, it is too early to say how many properties will be without gas and the extent of the impact of water in our gas network.
Our teams will be on hand in the TW10 area to continue to manage the situation, and we will be working with the local community to support our customers. We will continue to communicate with all of those affected so that they understand what is happening, and what support they can receive while we carry out the repair and restoration of gas supplies.
Finally, as we are still in the early stages, I would ask residents and business owners for their patience whilst we work to resolve this incident as safely and quickly as possible.
If customers affected by this incident have any queries please call us on: 0808 164 0819
Cadent engineers have been visiting each property affected by the water in our gas pipe since Sunday (20/07/25). We need to ensure every property is safely switched off before we can return gas to the network and then we will need to revisit each property again, to complete the safety checks before gas supplies are restored.
Unfortunately, this can take a few days to complete. We need people to be in but don’t worry we will continue to knock on doors if you are at work or need to leave your property.
These are the three streets where customers have been impacted with no gas due to water in the gas pipes.
To enable us to safely complete the repair there will be a small road closure on Hill Rise near the junction with Petersham Road and The Vineyard.
If you have any queries or need additional support please call 0808 164 0819.
This video will explain further the process we need to go through to ensure you get your gas supply back as quickly as possible.

Here at Cadent we support the Government’s plans to reach Net Zero by 2050. That means we’re backing the introduction of hydrogen as a low carbon alternative to natural gas for the future. We know people love the controllability of gas and, with our network already in place, it makes sense to switch to the lower carbon alternative offered by hydrogen, which we believe can keep homes and businesses warm for generations to come.
