Quarterly bill - £13000.
In May 2025 we received an estimated quarterly bill from British Gas which contained a daytime reading that was estimated at approximately £13,000/40,000kW too high. While they acknowledged the error, they appeared incapable of resolving the issue within any given time frame. We'd had a lot of recent meter readings issues and this was the last straw. We moved to another supplier.
British Gas did not send a final bill. A complaint was eventually raised with the Ombudsman, who ruled in our favour. This at least prompted the final bill, but British Gas did not refund the credit we were due within the time limit specified.
We moved suppliers in May, as of late October this still has not been resolved and we are considering issuing proceedings.
Our new supplier, a little pink sea-going creature, is a breath of fresh air...
