Corona Energy Avis 

Spoke with Fiwa this morning, regarding a Password query, she was extremely helpful, problem now solved - very much appreciated Thank you.

I have been guided very nice to resolve my query

Not too long a wait before I was connected to an advisor. His name was Bilal, he was very helpful and answered all my questions.

Bilal Nahim dealt with my request quick and sent the evidence i needed which made my job a lot easier.

Haseena has been very helpful addressing an invoice query for me, going over and beyond. Thank you

Brooklyn very helpful in customer service. Disappointed I can't see energy usage on the web portal.

Great customer service from Bilal Nahim. After spending 30 minutes on web chat without getting anywhere, I decided to call instead. Bilal dealt with my query quickly, in a friendly and calm manner, and was very helpful throughout. Thank you!

5* for our interaction today with Haren within the Customer Services Team

Great experience today with Fiwa would recommend this energy supplier

The saga continues.
LOA failed to be added to the account on x3 occasions.
Customer still awaiting portal link access.
Contact details not removed for a point of contact that should not have access to the account.
Collections activity started, despite a variable direct debit being in place.
You cannot make this up!

I had a great experience with Fiwa, who handled my query with professionalism and care. She listened patiently, explained everything clearly, and ensured my issue was sorted without any hassle moreover saving me valuable time! Really appreciate her help and the excellent customer service!

Nika was very helpful and quickly answered my queries, thank you.

I rarely leave reviews, but today I just had to! Fiwa was excellent – her patience and communication were brilliant. Thank you again!

I received an excellent response to an issue today from Customer Care Exec. Nika Mandiki, who sorted out my issue straight away. I wish all utility companies could be this easy to deal with.

Worst company I've ever had the misfortune to deal with!

Only interested in gathering payments and not interested when their bills are clearly wrong.

Avoid avoid avoid.

Contacted on the live chat and spoke with Nika and they solved my problem in under 2 minutes, really good service. Thank you.

We have been a commercial customer and arranged a new electricity contract with another supplier several months before our Corona contract was due to expire.
Despite this, Corona has now blocked the transfer and says that because a termination notice was not served in time, we have been automatically committed to them for a further 12 months.
What I find particularly unacceptable is the way the renewal was handled. Corona's own renewal information says they will write approximately 60 days before the end of the contract with a renewal price, allowing the customer to review it and decide whether to renew or terminate. In our case, I did not receive a renewal offer by email or post setting out the new rates for me to consider before the termination deadline.
I subsequently received correspondence dated 14 September stating that our contract had been renewed, yet the documentation itself says the renewal letter should detail the renewal price. The correspondence I received did not provide me with those renewal rates. Document_2026-10-01_161343
Corona is nevertheless holding us to another 12 months and blocking our move to the supplier we contracted with months ago.
The financial consequence for our business is substantial — based on our calculations, approximately £15,000 additional cost over the year.
I fully understand that commercial contracts have terms and notice periods. My complaint is about the lack of clear and timely communication of the renewal price before automatically committing a business to another 12 months, particularly when the customer had already arranged to move supplier

Called today to arrange portal access for one of our customers. Spoke with Bilal Nahim, who was extremely helpful, waited while I forwarded a copy of the letter of authority to allow us to act on customer's behalf and then sorted the access for the customer on the call.
