About

Who is npower?

Registered as Npower Limited, npower 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.

The company is headquartered in Swindon, where it runs its senior management, customer operations and regulatory liaison with Ofgem.

npower was founded in 2000. 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.

npower is part of the E.ON UK plc (subsidiary of E.ON SE, Germany) group, which provides shared governance, financial backing and a broader pool of expertise in trading, hedging and regulatory work.

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

npower — frequently asked questions

Brand acquisition — npower's residential customers were progressively migrated to E.ON Next after E.ON UK acquired the supplier from Innogy in 2019. The npower consumer brand was fully retired in 2022.

Existing customers were transferred to E.ON Next 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 npower 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 (E.ON Next) 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 npower 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 npower statement before paying.

You can complain about the conduct of npower (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.
