It's good to know the work will be carried out properly and certified. The only reason i was wondering was because i had an extension done to the lounge and wanted sockets low but there were minimum height requirements for the sockets. I believe it was minimum 45cm from the finished floor.
Looking forward to seeing your finished cinema room. I can tell already that it will be pretty damn good!!
He is right you cant have sockets that low. Not that it matters as nobody is going to really know but they now must be 45 cm from floor level.
