Can I cancel a rollover contract?

The grounds worth arguing

• No rollover clause. Ask for a copy of the contract terms you actually agreed. If there is no rollover provision, the supplier has no basis for the new term.
• You were not told. Micro-business customers must be given their contract end date and the date notice is due. If that information never appeared on a bill or statement, say so.
• The notice period was longer than 30 days and you are a micro business. That exceeds what Ofgem allows.
• You did serve notice and it was not actioned. Suppliers must take all reasonable steps to acknowledge a termination notice within five working days — produce your sent email.

How to put it

Write, do not phone. State the account number and site address, say that you did not agree to a new term, set out which of the grounds above applies, and ask to be released from the rollover with the account placed on out-of-contract rates while you arrange a replacement. Keep it factual and give them a deadline.

If they refuse

Ask for a deadlock letter. Micro businesses can take a complaint about a supplier — and about a broker — to the Energy Ombudsman through the alternative dispute resolution scheme, free of charge, once the complaint has reached deadlock or eight weeks have passed. That route is often what unlocks a stalled case.

Meanwhile, price a replacement contract so that you are ready to move the day you are released. Our full guide covers the sequence: cancelling a rollover energy contract.
