Sainsbury's Energy

Sainsbury’s Energy is a partnership between Sainsbury’s and Powershop - a small energy firm owned by Npower. Find out whether Sainsbury's Energy is the right supplier for you.

Sainsbury's Energy says customers will get ‘top-notch service’ and earn Nectar points for switching. Plus it will match your use with electricity generated from renewable sources. 

Gas and electricity is supplied to customers’ homes by Npower. But the Sainsbury’s Energy’s website, customer service and bills use the same systems as Powershop, Npower’s subsidiary.

Sainsbury’s Energy used to be a partnership between the supermarket and British Gas, but this ended in April 2019. If you are a former Sainsbury’s Energy customer: find out what this means for you.

Customers can manage their account online or via Sainsbury’s Energy’s mobile app. You can use the app to check your gas and electricity use, send meter readings and change the amount of your direct debit, if you don’t feel it matches your use.

See how Sainsbury’s Energy’s prices match up to the rest of the market, and whether it would suit you, by using Which? Switch to compare gas and electricity prices.

What is Sainsbury’s Energy’s customer score?

When Sainsbury’s Energy was a partnership with British Gas, it received a customer score and star ratings in our 2019 energy supplier satisfaction survey. It came 20th out of 30 energy companies included. Overall, energy companies in our survey were rated by 7,429 members of the public. The results don’t tell us what customers think of the energy firm now it has a new company backing it.

Powershop, the company now behind Sainsbury’s Energy's customer service and systems, was too small to be included in our 2019 survey.

Npower, which owns Powershop, ranked joint 28th. Find out more about Npower.

Sainsbury's Energy relaunch - April 2019

New customers switching to Sainsbury’s Energy will have gas and electricity supplied by Npower.

But Sainsbury's Energy customers will have a 'dedicated customer service team' and access to an app to check energy use and send meter readings. Both these and online billing will come from the systems used by Powershop and Npower's other white label brands, rather than Npower's own systems.

Sainsbury’s Energy is selling one 12-month fixed deal which is available only to new customers (so you cannot be an existing Npower or Powershop customer).

You’ll need to manage your account online, or via its app. Dual-fuel switchers can earn 4,000 Nectar points.

Powershop started selling electricity in the UK in 2017. Originally it was set up in 2009 in New Zealand by one of the largest power suppliers there. 

The Sainsbury’s Energy and British Gas partnership ended in April 2019 

Until February 2019, Sainsbury’s Energy was a trading name used by British Gas

After the partnership ended, customers were switched to British Gas. This was completed in April 2019.

If you were a Sainsbury's Energy customer before April 2019, your tariff, payments and account number should have remained the same. British Gas should have contacted you in April when you were switched over to it to tell you how to access your online account.

You can submit meter readings as usual or, if you have a smart meter, British Gas will be able to read it.

If you were in debt to Sainsbury’s Energy, it should have moved to your British Gas account. The same should have happened if you’re in credit.

Sainsbury's Energy electricity sources

Sainsbury’s Energy states that it will match 100% of your electricity use with power generated from renewable sources, subject to availability. But it states that ‘there are no added environmental benefits to this tariff’.

At the moment, Npower (which supplies electricity to Sainsbury’s Energy customers) has a fuel mix which is not 100% renewable. But it says that it plans to increase the proportion of renewables in its fuel mix to match Sainsbury’s Energy customers’ use.
