Need to get inside a substation?

Do you need to get access inside a substation to complete some work? Our engineers can arrange this for you.

Typically customers request this when:

  • Building or working near a substation

  • Carrying out maintenance work inside a building with a substation

  • Checking fire alarms located within the substation

If you notice any damage to one of our substations or think your situation is dangerous, please stay away from the equipment and call us 24 hours a day on 0800 31 63 105 or 105 (free to call from a landline or mobile).

An electrical substation is essential for keeping the lights on

We have hundreds of electrical substations in London, the South East and East of England powering homes and businesses. Our substations can be located on or close to customer land so occasionally customers need access when carrying out work nearby. Substations can also be found inside large buildings. If access is required, one of our engineers can arrange this for you.
