  • Safety and Emergency: Who to call and what to do in an emergency involving electricity, gas, carbon monoxide or any of our assets. Stay safe however you're connected to us.
  • Leisure activities near overhead power lines

  • Overhead electricity lines are normally bare (uninsulated) and if an object gets too close it is possible that a ‘flashover’ can occur, where electricity will jump over a  distance to reach earth via the object.  This can kill or cause severe shocks and burns to any person nearby.

  • In order to prevent this happening, there are minimum safety clearances between overhead lines and the ground, roads or objects on which a person can stand.

    Please take note of the advice below.

    • Never fly kites or model aircraft near overhead power lines
    • Be careful to avoid lines when operating light aircraft, hot air balloons, gliders etc.
    • Fishing rods and poles made from carbon fibre and similar materials will conduct electricity.  Fish at least 30 metres or more away from overhead lines
    • Do not light fires beneath overhead lines
    • Do not aim shotguns or pistols at overhead power lines

  • Emergency?

  • Steps to take if you spot a potential hazard on or near an overhead electricity line

    Do not approach any hazard, even at ground level. Keep as far away as possible. Follow the six steps below:

    1. Warn anyone in the vicinity to evacuate the area.
    2. Call our 24-hour electricity Emergency Number 0800 40 40 90*.
    3. Give your name and contact phone number.
    4. Explain the nature of the issue/hazard.
    5. Give as much information as possible so that we can identify the geographic location – ie. town/village, numbers of near-by roads, postcode and (ONLY if it can be observed without putting you or others in danger) the tower number of an adjacent pylon.
    6. Await further contact from a National Grid engineer.

    * It is critically important that you don't use this phone number for any other purpose. If you need to contact National Grid for another reason please use our Contact Centre to find the appropriate information.
