Awful! I moved into a flat recently and found the electric meter had been bypassed. Being the honest chap i am i rung British Gas to tell them. Within an hour i got a callback to meet them at the property and they will fix it and install a new meter. I went to the flat and 3 hours late a big burley man turns up and asks to look at the meter which i showed him. He then advised me he didn't know what he was looking at and needed an engineer. A couple of uncomfortable hours with the burley bloke and an engineer turns up. He then disconnected everything, took the meter didn't install another and left me with no electricity. I then found out the burley bloke was security for the engineer. British gas are a joke, if you ever find yourself in the same situation i recommend rinsing them for as much as you can....
