Electricity Network - Underground Cables

Simply identify the area you are interested in and open the appropriate document. Our high voltage underground electricity cables are shown in green against a general map background.
By using the Risktable you can assess the risk depending on what you are planning to do and how close it is to us.
If the risk is moderate or high please read the Electricity Underground Cables Guidelines.
If the risk is high please contact us at least seven days before you plan to start work on site.
If you have a compatible GIS you may be able to use the underground cables shape files that represent this network.
For how to contact us or our gas distribution colleagues please see the contact information map.
Please do not hesitate to contact us if you are in doubt or need further guidance or support.
