Same great service over 5 years

We have been using Sainsbury's energy for 5 years now and generally on fixed-price tariffs which we regularly check and find competitive. On the very few occasions we have needed to make an online enquiry, the response has been prompt and efficient. We needed an annual summary of energy usage for our EPC and found that this information was not available through the dashboard. Our request was answered within 24 hours and the summaries e-mailed to us the following day. Well done!

Not recommended

If I could give no stars I would. I planned to change to Sainsburys Energy but changed my mind before the switch. Despite canceling on 5th February with a start date of 13th February, they still took the first payment and 3 chasing emails and more than a month later, they seem to think it is acceptable not to have returned the funds. So only start a switch to them if you are absolutely sure you won't change your mind.

Contacted SE via Whatsapp seeking a reduction in my monthly direct debit amount since I have recently switched from gas/electric with SE to gas only. It did take a while to persuade them that the DD amount would be too much going forward but eventually they relented and reduced it by more than half (!!). They were polite and communicative so all was good there, though I'm puzzled why it took so much to and fro to get to the obvious conclusion. anyway altogether pretty good.

Had a good experience with one of their energy specialists called Shane

Just switched to this company. Had a dysfunctional automated email asking me to send my meter readings up to 5 days before the switch which turned out to be wrong - it needs to be on the day of the switch. Got in touch with a customer adviser called Shane who was excellent - admitted that the email was misleading and he has passed it onto the internal team. Thanks to sensible responsive people like Shane in the loop, I am now sticking with this company.

This must be the worst energy provider…

This must be the worst energy provider I have ever come across. Joined and they did nothing then cancelled within 14 days cooling off period they did nothing now I have exit fees and they have taken money from my bank account. Complained and they did nothing. Asked for a manager and still they’ve done nothing to resolve the issues! Beware and stay away!

AVOID AVOID AVOID AVOID AVOID

Absolute joke, not a decent company. I was a happy customer for a past 2 years but unfortunately I’ve lost my job around Christmas. In January my fix tariff end so I had to find cheaper supplier as this one become slightly expensive taking under consideration other players on the market and I was still without any income at the horizon. So I swapped to another supplier at 16 January but these guys were still holding my £250 in credit that I build over the year. Right now we have 27 February and Sainsbury’s Energy still holding my money. Meantime they had a problem to produce my final statement because they were missing readings from my “smart” meters they’ve installed, then they state they forget to charge me for like 3 or 4 days in between switching to new supplier and crème de la crème at the end: today they informed me that they will issue a refund of my money around 16th march (sic!) which according to them is a standard procedure. I’ve clearly mentioned my situation when I was talking to their CS but I guess only we “customers” are obliged to pay them money as soon as they issuing bill, they are not. So if you want hassle free cheap energy supplier absolutely avoid them. Crap company with same crap CS without any compassion to other human being.

Hi there Przemyslaw.

Thank you sharing your experience. I'm sorry to hear about the delay in receiving your refund and the issues you encountered with the final statement and meter readings, especially given your circumstances.

I have requested your account details to enable me to look into this for you and rectify any issues you have had.

I hope to hear back from you soon.

Thanks

No contact

What went wrong? Getting back to your existing customer with their renewal quote would be a good start. I'm on the EV5 contract at the moment until March 1st. Over the past two weeks I have placed two requests for a new quote and been on Whatsapp asking and all I get is "we will be in contact". If Sainsburys doesn't want my custom, Octopus Energy is more than happy to sign me up.

Hi there,

I am incredibly sorry that you haven’t received your renewal quote yet, especially with your current contract ending so soon on March 1st. I completely understand your frustration; when you have an EV, having that certainty over your next tariff is essential, and "we will be in contact" simply isn't specific enough when you're on a deadline.

I would love the opportunity to keep your custom and get this sorted today. I have requested your account information via Trustpilot so I can access your details. Once I have those, I will prioritise getting those renewal options over to you immediately so you can make an informed decision before March 1st.

Best regards,

Incompetent company

This company tells you how much you should pay; in my case, they reduced my monthly payments. While this may sound good at first, when you decide to move or sell the property, they present you with a very large bill that you will struggle to pay in full. Absolutely incompetent. AVOID.

Hi there,

Thank you for sharing your feedback. I’m very sorry to hear that the reduction in your monthly payments has led to an unexpected and stressful bill at the point of moving; I completely understand how frustrating it is to feel like you've been left with a shortfall when you were following our recommendations.

Our goal is always to keep payments accurate, but it’s clear that in this instance, the balance wasn't managed correctly for your actual usage. I have requested your account information via Trustpilot so I can investigate how your payments were calculated and look into the final bill for you.

Once I have your details, I will contact you directly to see what I can do to help and discuss a manageable way forward.

Best regards,

Siobhan

Hi there,

I am very sorry to hear about the confusion regarding your gas charges. I understand how frustrating it is to receive a bill for a period you believe has already been covered, especially when using a prepayment meter.

I want to investigate this for you to ensure you aren't being asked to pay for anything twice. I have requested your account information via Trustpilot so I can access your details and look into the history of your gas meter and the charges from 2023.

Once I have those details, I will get in touch with you directly to clarify the situation and resolve this as quickly as possible.

Best regards,
