Energy contract end date

The date your current gas and electricity contract ends. This is not a statutory cycle — it is set by whatever term you signed with your supplier, so you tell the calendar the actual date from your contract rather than relying on a generic reminder.

Business energy contracts do not protect you the way domestic ones do. Miss the switching window and you can be rolled onto a deemed or out-of-contract rate automatically, often two to three times the rate you were paying, sometimes locked in for a further fixed term before you can move again.

Watch out for

• Waiting for the supplier to write to you before shopping around — by the time that letter lands, the best rates and the switching window may already have passed.
• Not knowing the actual end date because it was set by whoever did the original fit-out, not the person now running the venue.
• Assuming a fixed-term deal renews on the same terms — most roll onto a deemed rate by default, not a like-for-like renewal.
