Sainsbury's Energy archive

Sainsbury's Energy was a white-label partnership brand. The original British Gas partnership ended in 2019 and the subsequent Npower / E.ON Next partnership wound down. Existing customers were absorbed by British Gas / E.ON Next.

Existing customers were transferred to British Gas under Ofgem's Supplier of Last Resort (SoLR) scheme — supply was never interrupted.

Your supply has not been interrupted: under the SoLR scheme, your supply is automatically handed to the successor supplier. Log in to the successor's online portal as soon as possible to set up your account, confirm your bank details and download any final Sainsbury's Energy statements while the legacy website is still online.

You are not required to pay any exit fee to leave the deemed tariff. Once your account is set up, compare current deals through Selectra to find a cheaper plan that fits your usage.

Yes. Customer credit balances on accounts at the date of cessation are protected under Ofgem's SoLR scheme. The successor supplier (British Gas) is required to honour your credit balance. Confirm the balance in writing within the first 30 days to avoid disputes later.

Yes — outstanding debts owed to Sainsbury's Energy transfer to the administrator of the company's estate, not the SoLR. You may receive a written demand for the outstanding amount from the administrators. Verify any demand against your final Sainsbury's Energy statement before paying.

You can complain about the conduct of Sainsbury's Energy (mis-selling, billing errors, customer service) to the Energy Ombudsman, even after the supplier has ceased trading. For complaints about the SoLR transfer itself (delays, incorrect tariff), the route is the same — Ombudsman first, then Ofgem.
