You are all being ripped off,in my opinion they must have you down as unskilled or something,you dont need "part p",its a load of crap,if your qualified you test & inspect your own work then they just sign it off,because you are not with a self cert scheme,when u are with a scheme all they do is notify building control on your behalf and charge you £400 a year for the privilage,its all a load of bullcack,i did a cu change,spoke to building control and they said its £65 for a qualified spark who is not on a scheme yet(sent quals in)bloke was happy and put me down on his list of sparks not on a scheme.just have to pay £60 per part p notifiable job,if they are charging £200-300 this is what they would charge to send a sparks who is on a scheme to check a diyer who had changed his own board(dont know why they would allow this)but thats how it is here and it makes sense,they dont need to send someone to test your work only a jobsworth to tick his form and walk down the road,if ever a sparks card was needed now is it.
