Power cut checks If you lose supply, check whether your neighbours have also lost their supply. If your neighbours DON’T have power: Call the emergency line: 0333 800 2016. If your neighbours DO have power: Check your trip switch. If the trip switch is still on, call the emergency number. If the trip switch is off, switch it back on. If it switches back off, one of your appliances may be faulty. Unplug all appliances and then reset the trip switch. If only part of your supply has failed and the trip won’t reset, there may be a fault with your internal wiring. Please contact a registered electrician. Check your electricity meter. Is the dial/display working? If not call the emergency number: 0333 800 2016.
