Good evening,

Thank you for your review.

We recently ran a "Refer a Friend" campaign with specific eligibility rules. To help me investigate this for you, I have requested your account details through Trustpilot.

Once you reply with those details, I will look into this right away and ensure any missing referral payments are credited to your account.

Hope to hear from you soon.

Best regards,

Siobhan

Poor Service

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.

Hello Mr Wilson,

Please accept our sincere apologies for the frustration and inconvenience this situation has caused you and your wife.

This is certainly not the standard of service we aim to provide, and I would like to investigate this matter for you. I understand how frustrating it is to consistently provide accurate meter readings, only to receive incorrect estimates and confusing correspondence in return.

I have located your account and will send you a direct message shortly. We can discuss your billing details securely there, ensure your meter readings are accurately updated, and get this issue fully resolved for you.

Thank you for your patience, and I will be in touch.

Take care,

Siobhan

Updating nectar card to account

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!

Changing tariff

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

This team are just simply the best

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

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.

Amazing supplier - 10/10

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

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.
