Sainsbury's Energy Anmeldelser 

Very easy to communicate via WhatsApp, very quick response times and Rebecca was extremely courteous and knowledgeable regarding all queries. This is one of the best customer relations companies I have come across - well done and thank you !!

I’d like to express my sincere thanks to Shane, Energy Specialist in the Digital Team at Sainsbury’s Energy by E.ON Next.

From the moment he took ownership of my issue, Shane has been professional, courteous and genuinely committed to resolving it. My tariff change had become quite complicated, but he kept me informed throughout, listened carefully to my concerns and explained everything clearly.

What impressed me most was that he didn’t just provide standard responses – he took responsibility, raised a formal complaint to make sure the issue was handled properly, and ensured my tariff would be backdated so I wouldn’t be left out of pocket. That level of customer care made a real difference.

Shane has been patient, knowledgeable and proactive throughout the process. He is a real credit to Sainsbury’s Energy and E.ON Next, and I hope his manager recognises the excellent service he provides.

Thank you, Shane, for your outstanding support and for going the extra mile to get everything sorted. It has been greatly appreciated.

Great customer service.

Have noticed a few reviews complaining about not receiving Nectar points. Unfortunately, I'm one of them. Sainsbury's Energy want to pass the blame onto Nectar, despite the incentive being offered by them, having a contract with them and signing up and providing my details on their website. Nectar appears incapable of understanding what's going on and I've ended up stuck between them. Its a shame as the switch went smoothly and customer service has generally been good. I think the issue lies in the fact that Sainsbury's Energy is actually Eon and Nectar is a separate company, so the communication between them seems non existent - basically Sainsbury's Energy will just fill in a form on your behalf and pass it onto Nectar, who don't seem to have a clue. Unfortunately had to raise a formal complaint and feel that it's likely to end up with the ombudsman as I feel a little duped into switching. Maybe switch if you want a decent price for your energy. At the moment, I wouldn't be swayed with the bribe of extra Nectar points.

I used the WhatsApp chat to deal with a problem regarding switching and tariff information.
I was in contact with Shane who worked quickly and efficiently. He ‘listened’ to what I had to say and clearly understood the problem. He looked into the problem, found solutions and guided me through.
The problem only arose due to poor communication from Sainsbury’s Energy. I asked for a quote on their EV tariff and when it came there was no instruction on how to proceed. Once I had got through the first hoop I wasn’t notified that the switch had happened 🥺. I later found out that the switch had only involved the electric and I had a different contract for my gas. Shane sorted all this out for me quickly and efficiently.

Quick and helpful response

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
