Sainsbury's Energy Reviews 

Moved from Octopus 2 weeks ago been inundated with emails and text messages about having new smart meters installed don't even want them. Given a phone number to call at EON was the general number so after ages giving all details was then transferred to another agent working from home (dog barking in the background). Asked for all details yet again then after ages said she need to contact another department. Said we would get a call back. 2 hours later no call. Wish we had stayed with Octopus.

Professional and friendly service. Dealt with my issue in a timely manner with no problems.

Absolutely the worst energy company I have ever dealt with.
I was unfortunately with Sainsburys energy for 20 days as the previous occupier was already with them during that 20 days the house was completely empty but Sainsburys provided me with a bill of £250 for 20 days of not using anything. When I actually moved in I swapped to Octupus energy and was only charged £109 a month that was with the hot tub on 24/7 and using heating a lot anyway I disputed the bill with Sainsburys it took them 6 months to come back to me and tell me to pay £170 because they had made an error I paid it then 3 months later they sent me a random check for £88 because they said they miscalculated the original bill then two months later they told me I had to pay them back £37. This if all for a 20 day bill back in February for an empty property 10 months later they are asking me for money for a bill I already cleared and paid that was extortionate for an empty property. They rip customers off worst company night mate to deal with

Whatsapp chat was a little slow to respond ended up making a phone call instead, Whatsapp finally caught up!

Hayley was very helpful and sent me links to find out about my Warm Home Discount application this year. Always a grey area where DWP say energy company organise it and energy company refer you back to DWP. I will enquire again at the end of Octiber when applications are open.

Excellent professional support. I particularly appreciate using WhatsApp for communication, as it allows me time to phrase my questions clearly, attach screenshots, and maintain a digital record for easy reference — ensuring I always receive the most accurate and helpful responses.

phoned regarding my present contract which expires in a few weeks.
gentleman on phone was polite and helpful.
conversation took less than 5 minutes..
im a happy customer.

Wry prompt response when leaving the service that offered a better rate. Very professional and quick.

I've been communicating over WhatsApp with the team. This is really helpful. Much better than email or phone, especially if you are dealing with more than one query

Staff are knowledgeable and helpful

I have been with Sainsbury’s Energy for a very long time. I am sir-post to get an extra 2 Nectar points for every pound I spend in Sainsbury’s. Normally these points are credited at the beginning of each month for the previous month. Today the 2 September 2025 I checked my Nectar account and was angry to see that I had only received 2 x 17 Nectar points when I know that I spent more than £17 in August. So I then checked ho much I did spend in Sainsbury’s in August and I spent a total of £99 which means I should have receive 2 x 99 Nectar points. This is not the first time this has happened and I bet it will not be the last.
One has to keep a close eye on every company nowadays that one deals with because every company throughout the world is very untrustworthy nowadays.
😡😡😡😡😡😡😡😡😡😡

I've always had good service from Sainsburys Energy. Yesterday I needed to speak with a real person about renewing my contract, as I had a couple of queries. It was painless, I got through quickly and having answered a few "bot" questions got put through to Ashley who was very helpful and between us we sorted everything. Which is exactly what I expected.

Hayley was very helpful in answering my questions regarding changing tariffs and sorted everything quickly for me.

An unfortunate, and for me, distressing situation during the switch process from another supplier. Ashley's attitude was understanding and sympathetic...his response was quick, professional and effected an immediate resolution. I will have no hesitation asking for him the next time I have a problem. Thank you.

Awful communication, unhelpful and rude staff. Would award zero starts if I could. Just go with Octopus instead and save yourself the hassle

Very good customer service

Friendly yet professional and knowledgeable service

Very Helpful person all sorted in no time

I couldn’t get what I wanted online and what’s apped for help. The agent was able to change my tarrif to start when I wanted and all was sorted out. No problem at all

I changed my tariff which was about to expired but the confirmation email was showing a different rate from what l have chosen.it was easy to sort it out by WhatsApp very quickly.
