Termination notice changes
If you are a SME customer and would like to switch supplier, you no longer need to send us a termination notice but will be unable to switch until the end of your fixed period. You’ll still need to pay any outstanding balance before you switch, or we may object.

Emergency numbers
Electrical emergency or power cut? Ring 105 (free) to reach your local electricity distribution company.
Opus Energy supplies electricity, but it is your local electricity distribution company that’s responsible for power cuts, and the wires and cables that connect you to the National Grid.
For more information, go to www.powercut105.com
Gas leak, carbon monoxide leak or no gas supply? Call 0800 111 999 to reach the National Grid Emergency Service.
If you smell gas or have a carbon dioxide leak, turn your supply off at the meter, air out the area, extinguish any naked flames and don’t turn electrical switches on or off.
