Review summary

Created with AI, based on recent reviews

Considering 97 reviews, reviewers had a great experience with this company. Customers frequently praise the helpful and knowledgeable staff members who handle energy tariff changes and general account queries with exceptional politeness and professional dedication. Consumers genuinely appreciate the fast response times and convenient messaging communication methods available for sorting out everyday account matters smoothly without experiencing unnecessary operational delays. However, some reviewers were not happy with unexpected billing complications and inaccurate estimates received on their accounts after updating their service plans. A few other people also felt that communication broke down when promised callbacks completely failed to happen or support channels proved frustratingly unhelpful.

terrible sadly… …

at least 3 times a year i get my bill doubled for absolutely no reason or there’s an error or my smart meter is apparently not reading even though it’s new. sainsburys are unfortunately the worst energy supplier i’ve ever used and im so relieved i have swapped to Octopus. with sainsbury’s i was often very stressed to get an email 5 days before my payment due and it would be doubled unnecessarily. , Octopus have been hassle free, transparent, and fair. thank goodness,

Reply from Sainsbury's Energy

Good afternoon Emma,

Firstly, please accept my sincere apologies for the delay in our response. We've had some system issues today that we weren't aware of and so I've only just seen your review to be able to respond.

I am truly sorry to hear about the consistently stressful experience you've had with your billing and smart meter issues, and that you felt your bills were unnecessarily doubled. It's clear that receiving those emails just days before payment was causing you significant stress, and I sincerely apologise that our service did not meet your expectations for reliability or transparency.

I understand your relief at finding a provider who offers you a hassle-free experience. While we're sad to see you go, your feedback is incredibly valuable, and I appreciate you sharing it. We are always striving to improve our services, and your insights will certainly help us in that effort.

I have requested your account information so I can look into this for you to ensure we were diligent in your payments and to explain the price increases that occurred.

I hope to hear back from you.

Warm regards

Siobhan

Sainsbury's Energy

I have been with Sainsbury's energy on and off for about 12 years.

I like the telephone customer service but dislike the robot help when calling.

I needed to call and talk to someone from customer service team because I couldn't find my latest bill on my online account.

Great Experience

I want to express my gratitude for the outstanding service I received from Tarryn at Sainsbury's. From the moment I spoke with her, she was attentive, patient, and genuinely interested in helping me. Tarryn provided all the information I needed and ensured that my concerns were addressed. Her professionalism and kindness truly stood out, making my interaction with Sainsbury's a positive one. Thank you, Tarryn, for your exceptional assistance!"

Thank you Sainsbury’s Energy

We’ve been with Sainsbury’s Energy for a few years - I know energy bills are a bone of contention but given that we have to pay them, so it’s less stressful if you have a company you feel confident with. If I’ve ever had to contact them, they reply swiftly. Up to now I’ve always given readings online & then the email Invoice arrives promptly. Now we have to change meters due to RTS changeover & Ashley is proactive in helping us sort that out.

Very poor customer care

I provided my meter readings on the day I took possession of a vacant property, then supplied meter readings 8 weeks later as the property was still empty and no bill had been sent. When I eventually received a bill it was accompanied by a letter saying £25 had been added to my account for the non-payment of a non existent bill and informed me that my account was being passed to a debt collection agency.

Do not go with Sainsbury for your sanity

I am totally stressed , last month said my balance was £3000 + in credit i asked if it was a joke, they said they were investigating it. Now telling me i owe them £820.90 this is because they apparently have not charged me correctly, from 2021 and their system has made errors. I have paid what i was requested every month by direct debit and mainly been in credit. I already pay over the odds for gas and electric. Look out if they audit your account and they have undercharged. . I am a pensioner no way i can pay this! Told thrm
I shouldn’t pay for their errors! Waiting for feedback. Lodged a complaint!
Wayne contacted said they cant take money gir more then 12 months ago i said why then was it put on my account, he stated in order i contact them to investigate. Im not sure i agree mor vulnerable people without a voice may have just paid or become very distressed. I am not happy with their explanation. I have also had lots of issues trying to collect my reward nectar points! Not good enough.

I can't thank Ashley enough for helping me

I can't thank Ashley enough for persevering with my issue and for arranging for a meter engineer to call at my house today. I really felt that he wanted a good outcome for me. The engineer has yet to arrive so I can't comment on the outcome of his visit but I'm hoping for the same positive result

Total shambles, I had a stroke in January and was in hospital until February, missed a payment but cleared arrears upon leaving hospital, staff at eonnext who manage the accounts totally incompetent! Now negative markers on credit file that they wont discuss as its not their problem! Zero customer service and ceo email replies with zero help!! Total shitshow **** stay away****

Transferred to a different energy…

Transferred to a different energy supplier. They didn't start my refund of credit balance until I contacted them and then 7-10 working days to receive payment is not acceptable in this day and age. I managed to send a payment this morning to someone from my account which has already arrived. Not just Sainsbury's that take this long but it's wrong that anyone can take this long to process a refund.

Fabulous service whenever you need it.

If I told you that I'd messaged my energy supplier on WhatsApp after 5pm on a Sunday evening, got a reply from them that evening, (within 10 mins), got a quote for a new tariff and got transferred onto that tariff, you might think I was making it up - but I'm not - Sainsbury's Energy sorted it all. A shout-out to Shane at Sainsbury's Energy for his help and professionalism.
