Don't be fooled by BG. Rolls Royce Normally with them the only one who gets that is their salesman. Customers get a Reliant Robin
LOL!
Possibly. To be honest, I know friends of mine who signed up for a BG service scheme and when push came to shove, the £30/month (or thereabouts) was for a plan which didn't cover the parts which were most likely to break! (Surprise, surprise...)
Only time I used them was when they were doing that one cost repair thing (don't know if they still do) when it was £95 regardless of what was wrong. They ended up putting in £300-worth of parts over an afternoon's labour. After that they black-listed my boiler. I won!
