About

Who is OneSelect Energy?

Registered as OneSelect Energy Limited, OneSelect Energy uses this legal name for Ofgem licence filings, contracts and any formal communications. The trading name customers see on bills is the shorter, more recognisable form.

OneSelect Energy was founded in 2014. The supplier operated under a domestic-supply licence until its closure, with a track record of customer service and billing publicly documented for the years it traded.

The company is regulated by Ofgem, the UK's energy regulator, and its complaint handling falls under the Energy Ombudsman alternative dispute resolution scheme.

Common questions

OneSelect Energy — frequently asked questions

Supplier collapse — OneSelect Energy ceased trading in December 2018. Customers were transferred to Together Energy under Ofgem's SoLR scheme.

Existing customers were transferred to Together Energy 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 OneSelect 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 (Together Energy) 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 OneSelect 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 OneSelect Energy statement before paying.

You can complain about the conduct of OneSelect 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.
