Sainsbury’s Energy has announced today (23 April) that it has partnered with big six supplier Npower.

The supermarket chain, which had a white label agreement with British Gas since 2011, transferred all its customers to British Gas on 14 April.

Sainsbury’s said it will offer its energy customers 100 per cent renewable matched electricity.

From today customers are able to switch to Sainsbury’s Energy Fix and Reward v1 tariff at an average annual bill value of £1,040 – below Ofgem’s standard variable tariff price cap. The energy provider will also be linked to the Nectar card scheme.

Simon Stacey, managing director for home and business at Npower, said: “Working together with one of the UK’s largest supermarkets to provide the power behind Sainsbury’s Energy is a really exciting opportunity for Npower.

“We’re confident the new deal will bring unique energy offers that Sainsbury’s customers will value, along with something extra for savvy shoppers who are looking for ways to save using Nectar rewards.”

Michael Luck, director of business development at Sainsbury’s, added: “We’re really excited to launch this new partnership with Npower.

“We want to help our customers live well for less and by collaborating with Npower we’re able to give people renewable energy while taking advantage of great savings and rewards.”

In July last year Marks and Spencer Energy and SSE announced they were ending their partnership of nine years.

Marks and Spencer later announced it was partnering with Octopus Energy.
