Who supplies Sainsbury's Energy?

E.ON Next. Sainsbury's Energy is a brand, not a licensed supplier — its own legal pages state it is “a trading name used under license by E.ON Next Energy Limited” (registered in England and Wales, no. 03782443). Many guides still say British Gas, which was the historic arrangement and is now out of date.

What that means for you

Your gas and electricity are supplied, billed and serviced under E.ON Next’s licence, so E.ON Next’s customer-service record and complaint-handling are the ones that matter — and they are measured officially, where Sainsbury's Energy as a brand is not. The Sainsbury's Energy name mainly changes the tariff line-up and the Nectar-linked rewards attached to some of them.

If you are weighing Sainsbury's Energy up, read E.ON Next’s official Citizens Advice star rating — that is the regulated service score behind this brand.

4.3 / 5

From 3,133 reviews · checked 16 August 2026

⚠️ Sainsbury's Energy has fewer than 25,000 customers in its own right, so Citizens Advice does not publish a star rating for it. We will not invent one. The Trustpilot figure above is Trustpilot’s, refreshed weekly and dated; for an official service score, use E.ON Next’s.

Sainsbury's Energy tariff range — what we hold

Counted from our live tariff feed on 16 August 2026. Unit rates and standing charges vary by distribution region and meter type, which is why one named tariff becomes many combinations — and why a national “price” for any supplier is meaningless until you enter a postcode.

Is Sainsbury's Energy cheap?

There is no honest national answer. The same Sainsbury's Energy tariff is priced differently across the fourteen distribution regions, and whether it beats the £1,723 Ofgem cap depends on how much gas and electricity you actually use. Ofgem has confirmed the October–December 2026 cap at £1,723 a year on its updated consumption basis, effective 1 October 2026, so a fix taken now locks today’s rate before that rise. The only way to know how any tariff stacks up is to price it against the whole market on your own address (cap figures verified September 2026).
