Sainsbury's Energy Reviews 

I switched to Sainsburys energy at the beginning of February 2026. I should have received 8000 nectar points for switching. 4 months later I still haven’t received them. Sainsburys energy say it’s not their problem & that I should take this up with nectar. I have done this with no joy. I would not recommend switching to Sainsburys energy.

Sent a question on WhatsApp and answered very quickly. Follow up questions also answered quickly I was given very comprehensive information on choosing a new tariff.

Gave me 1st class service and advice

False sign up advertising claims, sigj up we guve you this MAKE IT KNOWN YOU GET NOTHING UNLESS YOU REFER FRIENDS. SO THERE IS NO GAIN FOR YOU JOINING THESE CON ARTISTS.

Quick reply to my question and new tariff sorted without any hassle at all.

On the 13th of every month we send two meter readings (one for night electricity, one for day) to Sainsbury's Energy. They are recorded on our bills as Customer Readings. However this month (May) the Customer Readings were wrong: they were estimates made up by Sainsbury's Energy, but wrongly described by Sainsbury's Energy as our Customer Readings. My wife has been involved in a fruitless exchange of emails with S.E. trying to get the matter rectified and has received some incomprehensible messages (from Edwina). We have even had a statement dated 12th June! What is wrong with this company? Why can't they send us an accurate bill?
Our account number is: A49B1C074.

Verry happy

I found Yemisi to be very helpful to me, explaining everything about Sainsburys Energy..
Thank you again Yemisi!

Rapid response from customer service via whatsapp on a bank holiday that actually fully resolved my issue.

I needed help to update my account settings. I found the help I needed through the what’s app option and all instructions were very clear and very helpful! So with clear instructions I managed to sort my account out successfully! Thank you Shane for all your help today!

Amanda was very helpful and gave me my dual fuel usage for the year. Also gave me the breakdown of a fixed tariff Sainsbury's have which is cheaper. Friendly and efficient. Thank you

Tried other ways sort out a small problem,to not a lotnof joy. I noticed you could use WhatsApp,which i did and within a matter of minutes my issue was resolved.

New to this provider but if the customer service continues like this I should be a happy customer.

Great customer service and speed as well

This team are just simply the best. Any questions or queries are answered promptly and effectively.
I was with the so called best service supplier in the UK however, I fail to disagree, Sainsbury's/E on are the best, by far

Woeful customer service from an advisor who was completely driven by the system. My account was in debit because of winter usage and I was asked to either pay the balance or increase my dd. It was impossible to get the advisor to accept that as we were now moving into the summer months the account would soon balance out. 12 emails to get nowhere and still waiting for compensation for time and aggravation. Will not renew. Eon is the problem I suspect.

Shane was very helpful and understanding when I had to postpone an installation appointment at very short notice

Easy to contact, query sorted and great service

Shane and Rebecca were a fantastic help when setting up my monthly payment and resolving an issue with a reward payment. 10/10 service.

Best energy provider I’ve been with

Rebecca the agent was excellent. She knew how to deal with my enquiry quickly and professionally.

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 priced having a company you can actually talk to and who seem to want to help is a massive plus point.
