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.

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.

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.

Much Worse than Scottish Power

Hey Sainsbury’s. What have you sent me a bill that says I will owe £40k plus after my tariff ends and I live in a 2 bed currently using a hot water bottle as heating.. you’ve not answered calls or emails. You website states we can contact you by WhatsApp or Facebook but neither work so what gives?Update it is now 19:35 I have been emailing spice after 5pm.Update it’s now 20:36 no call email or message.
