We have hundreds of electrical substations in London, the South East and East of England powering homes and businesses. We regularly maintain these, however sometimes we need your help to spot issues. If you’ve noticed an issue with a substation, please report it.
We'll always aim to book an engineer to visit at the next available appointment
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).
Free to call from a mobile or landline phone. Lines are open Monday - Friday, 9:00am -5.00pm.
