Installation of underground cables from Beddington to Addington

What are we doing?

We manage the electricity network delivering power to your area and connect and move power cables. Our engineers plan to upgrade the electricity network between Beddington Grid and Addington Grid in Croydon to maintain reliable electricity supplies for homes and businesses, manage increasing demand for electricity and support the drive to Net Zero.

What will the work entail?

We are installing new electricity cables along a 6.5km route between the two substations. We are working closely with Croydon Borough Council to plan our work and minimise disruption. 

Our team will excavate trenches to lay pipework (ducts) along the route. We will then return to open excavations at intervals along the route to pull the new cables into position and connect them to our electricity network. 

We will start work in October 2025 and aim to complete the project by the end of 2026.
