Sainsbury’s Energy Prices for Electricity and Gas Review

Sainsbury’s Energy offers a full range of energy products, including electricity and gas, and both as a dual fuel tariff for homeowners.

The product offerings from Sainsbury’s now utilise the E.ON Next renewable energy network.

Summary of Sainsbury’s Energy Offers

At Sainsbury’s Energy, you get the same choice of products at the same price as if you went directly to the E.ON Next website. The Sainsbury’s website for electricity and gas is just an affiliate branded site in any case. The energy supplied used to come from EDF and then British Gas with Nectar Points, but now they use E.ON for their energy relationship.

The main benefit of using Sainsbury’s rather than E.ON is the Nectar points bonuses you receive. There are three main tariffs on offer: a variable rate, a 12-month fixed-priced tariff and a 24-month fixed-priced tariff.

The Sainsbury’s Energy Products

You get to choose from the same E.ON Next product list which is as follows:

• Sainsbury’s Fix and Reward Fixed 12m allows you to fix your electricity and gas bills for around 12 months. The prices are lower than the current energy price cap, and there are no exit fees. You receive 6,000 Nectar points on switching and then a bonus triple points spent in Sainsbury’s stores. Typical prices of 44.78p per day and 26.35p per kWh.
• Standard tariff is usually the most expensive but you don’t need to pay by monthly direct debit and there are no exit fees. Typical prices of 44.75p per day and 26.35p per kWh.
• Sainsbury’s Fix and Reward Fixed 24m allows you to fix your electricity and gas bills for around 24 months. The prices are higher than the current energy price cap, and there are exit fees of £100 per fuel. You receive 4,000 Nectar points on switching and then a bonus triple points spent in Sainsbury’s stores. Typical prices of 44.78p per day and 23.74p per kWh.

The typical rates shown are from an online quote performed for a high-energy user during June 2026 based in London. Your prices may vary.

If you’re a low-energy user and spend a lot at Sainsbury’s, the 24-month product might be worth considering.

All tariffs used 100% renewable energy for the electricity tariff. You can manage your account online or through the mobile phone app.

Check out one of their latest customer reviews below:

“Surprisingly helpful and easy to deal with. Not what I was expecting at all. I called to make a change to my DD payment, and whilst they did that quickly, they also suggested a cheaper tariff that I should be on and then put me on it, all within 10 minutes or so. Very impressed. In these times of massively high energy prices, having a company you can actually talk to and that seems to want to help is a massive plus point.“
