Working near our assets

On this page, you'll find guidance and support for working near our electricity transmission assets, including overhead lines and underground cables. 

Working near our electricity assets

Are you proposing, scheduling, or designing developments close to our electricity transmission assets? Our electricity assets include overhead lines, pylons, underground cables, and transmission substations. 

For electrical assets, we do not authorise or agree safe systems of work with developers and contractors. However, we will advise on issues such as electrical safety clearances and the location of towers and cables. We also work with developers to minimise the impact of any of our assets that are nearby.

You can find out more about the basic safety and location of our assets by downloading our guidance document for working near electricity equipment.
