Do you think BC are bothered, with cut backs they have not got enough staff to deal with everything, had one couple of years back about notifying a unvented cylinder, they sent out a young girl from the office, she did not have a clue what she was looking at, talk about head in the clouds, think she was more concerned about what to were when she met her boyfriend, lot of cases its just a money making exercise , can you imagine them knocking on everyone's house and asking to see the bathroom, just in case they have fitted a new one !! Proberly more get done by DIY than trades. This job is getting over-run by a lot of stupid legislation, made up by office bods who cant tell one end of a spanner from the other, just more concerned with how to screw people over for more money, the way it's going you'll have to notify them on what colour toilet paper you use just incase it doesn't match your bathroom.
