Electricity assets

If you are proposing, scheduling, or designing developments close to National Grid electricity transmission assets, you can find out more about the basic safety and location of our assets by downloading our guidance document for working near electricity equipment.

Our electricity assets include overhead lines, pylons, underground cables, and transmission substations. 

For electrical assets, National Grid does 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 National Grid assets that are nearby.

Gas assets

If you're planning or undertaking work near high-pressure gas pipelines or associated installations you will need to take appropriate measures to prevent damage. Damage to pipelines, including pipeline coating, can lead to dangerous consequences. So, it's essential to follow the procedures outlined in our guidance document for working near gas equipment.

It is your responsibility to make sure that any work carried out meets the requirements of all other relevant health and safety legislation. If we believe that your work doesn't meet requirements, we will suspend the work until it does.
