Terrible Company - they cannot get the bill right even with smart meters. After moving to the year ago, I had 4 months of constant phone calls, chats and emails to get them to understand that I did have smart meters fitted (that they fitted!) The still insisted on billing me with incorrect estimates and meter readings from another meter that didn't even exist, I had to take several days off work to wait in for engineers to come and rectify the problem - one of which did not turn up and 1 turned up at 9 am when I was told 2 pm. When they did arrive they simply said - you already have smart meters so what's the problem!! The problem is British Gas have got no idea what they are doing. No apology or compensation offered and now you cannot even get hold of them at all (Due to COVID, just another excuse). I will NEVER use them again and have arranged for other members of my family to do the same. Just on one final point the website and app are terrible and do not give you any information at all (When they are working or displaying proplery that is)
