Have you never watched watchdog or any other consumer program ?[/QUOTE] Ok, on your advice I have just "FGI". The problems with BG fall into two categories. The first if the price that BG charge for their gas. I don't use BG to supply my gas, and AFAIK they cannot force me to switch to them if I use them to install a new CH/HW system, so that group of complaints don't apply to me. The second complaint group is their customer service. There's a hell of a lot of sites saying "complaints about BGs customer service have doubled/trebled to 'XYZ'", but I needed to dig a lot further to find out the other half of that figure so it'll make any sense. Depends on when the figures were taken, but it ranges from 1 in 400 to 1 in 1500 chance of having a problem. To me, thats not a number I'm bothered about. Even less when you consider that the cause of that doubling / trebling was the new estimated billing system they introduced for gas customers. Even less when you see that BG have admitted they have a problem and are investing money into providing more phone staff and fixing the cause of the problems. I can't find figures just for customers of their CH/HW installation section of the company, but they're going to be less than the above. Less than a 1/3rd, 1 in 4300 or so. Perfectly acceptable to me. If you've got anything contrary to any of this, please post it.
