This site is now closed.

As part of the UK's energy transition, all owners of generating sites in Great Britain are required to ensure that their installations are compliant with Engineering Recommendation G59/3-7.

If your equipment is already compliant, please confirm by submitting a declaration directly to your DNO.

If not, please ensure you make the changes as soon as possible to avoid enforcement action. You can find more information on how to achieve compliance here.

The contact details for each DNO can be found here.
