Tomato Energy: advice for affected customers

Below is a copy of a communication that we sent to customers who had a complaint about Tomato Energy open with us at the time of the company ceasing trading.

Dear customer,

As you may be aware, Tomato Energy ceased trading on 5th November 2025.

This means that they won’t be able to carry out any remedies we may have required in response to your dispute. As we’re unable to take further action, we unfortunately must close your case.

We appreciate that this will be frustrating and we’re sorry that we’re unable to continue providing support in resolving your dispute.

Tomato Energy and British Gas

British Gas has been appointed as your new supplier by energy regulator, Ofgem. As a consumer of Tomato Energy, you’re advised to:

• record a meter reading; and
• not switch suppliers before the transfer is completed

British Gas will be in contact in the coming days. Please be assured that any outstanding credit balances, including money owed will be honoured. If, once you’ve transferred from Tomato Energy to British Gas, you decide to switch, you won’t be charged exit fees.

If you have any queries or concerns about the way British Gas has taken over your energy supply, you should contact them in the first instance. You might find these pages on their website helpful.
