Avoid at all costs but most of these energy companies are equally useless to be fair.

4 months in, 35 phones call and they still cannot get the billing correct, goodness knows where they are getting the meter readings from but despite supplying them readings monthly they are still invoicing around £6,000 per month for around £550 per months worth of use, meaning a debt of £0 is showing as £20,000.

5 weeks ago they said they had arranged for Energy Assets to come and look at the non functioning meter and 5 weeks down the line Energy Assets are still awaiting the job to come and do the work.

Simple things the customer services can deal with, anything mildly complex they fall to pieces. Avoid.

I had to phone recently and spoke with Ellis who I have to say was extremely helpful and put my mind at rest during my account changeover. Explained everything clearly, good support.

Good company to start off with unless somebody screws ut up for you. THE POLICE

Good company to start off with, but when we were closed for 6 months as a police car crashed into our shop, they put us on an emergency tariff which consisted in an email at 6am every morning and 4 text messages on the shop phone every day! And we are closed weekends so monday was 12 texts… also said we could not change suppliers as we signed a contract in October 2025 until 2050! Did no such thing!!! So finally got away from this shithole after many phone calls and complaining, 5 months of the above for no fault of our own🤬 Company name.
