I never write online reviews but this was so shocking I had to share. this is quite comparable to a scam ! I am shocked that such things are allowed in the UK and performed by a large known corporation. and on top of that customer support was a nightmare, literally days and weeks of my work hours wasted just to get a hold of them. I was with them for 3 months only. I pay attention to my meter readings and take frequent photos, I use excel to calculate my actual electricity cost to the decimal. I had used 400 kwh which accounts to around 83£, I had already paid 60£ in direct debit so I only needed to pay 23£ more. They sent me a bill with £174 !!! there was no way 400 kwh cost 174£+ 60£. I called to complain and it took DAYS to get a hold of someone, they said "sorry there is an error we're gonna bill you £100 instead". I said that's still outrageously high for my actual readings. the guy got angry and started pressuring me to pay, I told them I will not pay until you give me the breakdown of my bill which they refused so I hanged up. I called again for DAYS before I could get someone. this time I was prepared: I told them ahead of time I have evidence of my readings, I took photos and videos and here are the exact numbers of my meter, so they lowered the bill to 90£, which was still high ! they lowered it again to 53£, which was still high compared to my actual usage ! I challenged again and kept asking for the breakdown, until they got the bill accurately down to 23£, which in addition to 60£ I had already paid results in exactly their kwh price of around 20 cents. As soon as the agent got the payment he hanged up on me !! as if to say he was not happy with me. In summary this was truly a nightmare, from the phone delays to the customer support to them trying to snatch 174£ off me instead of my actual final bill of 23£. INSANE, NEVER AGAIN SSE, NEVER !! I AM WARNING ALL MY FRIEND AND FAMILY
