SEFE Energy, formerly Gazprom Energy, is a business gas and electricity supplier with its UK sales headquarters in Manchester. It supplies over 30,000 organisations in Great Britain and says it became the UK's largest non-domestic gas supplier by volume again in 2026. It is ultimately owned by the German government through SEFE Securing Energy for Europe GmbH.

Worth knowing: SEFE Energy no longer offers new contracts to customers using less than 50,000 kWh of gas or electricity, so if you are a smaller existing customer, check with SEFE what happens when your contract ends. On 31 August 2026 it moved to a new parent company within the SEFE group, SEFE Energy GmbH, and says day-to-day operations are unaffected. Under EU rules, Germany must cut its stake in SEFE to no more than 25% plus one share by the end of 2028.

SEFE Energy deemed and out-of-contract rates

If your fixed contract ends without a new one in place, or you move into premises supplied by SEFE Energy without agreeing a contract, you'll pay its deemed or out-of-contract rates. These are typically well above fixed contract prices.

SEFE Energy publishes its out-of-contract and deemed rates as PDFs on its help and support pages.

See SEFE Energy's current published rates

For context: in Q2 2026, UK businesses using up to 20,000 kWh of electricity a year paid an average of 38.36p per kWh all-in, which spreads the standing charge across every unit and includes the Climate Change Levy. A bill shows a unit rate plus a daily standing charge, so use our cost calculator to turn your rates into an all-in figure before comparing. Prices for every business size.
