My building control charge almost £200 for a notification. They also require an EIC to be issued by a competent electrician. They state that if it is DIY then the DIYer must pay the electrician to issue the certificate. Its just too expensive and convoluted.
It is probably good DIYers that do a good job anyway that pay and idiots that havn't got a clue dont bother notifying.
I suspect that it causes more bad DIY.
The only thing that is probably keeping the fatailities down is that you can still freely buy cable, sockets, MCBs and the such like.
I took my time, I hurried up, The choice was mine, I didn't think enough
