Sainsbury's Energy

Sainsbury’s Energy is a partnership between Sainsbury’s and British Gas. Find out whether Sainsbury's Energy is the right supplier for you.

Sainsbury's Energy customers are supplied by British Gas - however that's set to end. Sainsbury's Energy says its aim is to 'support the UK's transition to a greener future by helping to reduce energy use and lower carbon emissions across the UK'.

There are advice centres in some Sainsbury’s stores, so customers can talk with staff about their energy use face to face. You can register and manage your account using an online service or over the phone.  

Sainsbury’s Energy stopped selling tariffs on 5th February 2019. It announced that its partnership with British Gas is ending and customers will be switched to British Gas in April.

Which? verdict on Sainsbury's Energy

Sainsbury’s Energy achieved a slightly above-average score in our survey (the overall GB average was 61%). However, it does sit in the bottom 10 of our 30 energy companies. 

Its lowest-rated areas include billing accuracy, helping customers to reduce energy use and save money, and value for money (3 stars). But it's the latter that customers spoke most about when taking part in our survey. 

Comments from customers included: 'expensive' and 'overpriced'. 

However, comments also indicated a general unhappiness with all energy companies rather than a direct issue with Sainsbury's. 

One respondent said: 'I wouldn't award any energy supplier more than 4 stars for value for money. They are all too expensive.' While another questioned: 'Does anyone think that they are getting value for money from their energy company?'. 

British Gas received two stars for value for money. 

An area that customers are happy with however is the online customer service. It was given the full five stars out of five. The 'user-friendly' website was largely praised, as was the quick response times. 

In our latest energy companies call-waiting investigation, Sainsbury's Energy took just 1min 49sec for a person to answer the phone when we called its customer services. It was in the top 10 quickest companies. 

Plus it responded to customer enquiries via its online form in an average of 22hr 30min in our latest snapshot investigation. This is a big improvement on 2017, when it took longer than 10 days, on average to respond.

Complaints-handling, customer service on the phone and bill clarity all got a respectable four-star rating, highlighting that although there is definite room for improvement, there are also areas Sainsbury's Energy are working well in. 

Customers rate Sainsbury's Energy higher than British Gas in all categories, bar 'helping you understand and reduce energy use', for which they both received three stars.

Pros: It offers face-to-face salespeople in Sainsbury’s stores and customers highly rate its online service

Cons: Customers feel like they could be given more advice on reducing their energy consumption or saving money
