Missus is having some building work done at the burger joint. The cooking area is moving, so there will be some movement of high power electrical feeds to the chip fryers etc, some new lighting, and the gas will be moving a few feet to the new position of the char grill. The contractor who is doing the work is supplying the trades to carry out the work that is additional to his 'bricks and mortar' stuff, so I'm assuming that they are all 'proper' ones. Should they be issuing any new paperwork in regard to the work that they are doing i.e. something like a gas safe certificate and a certification for the electrics, or is it enough that they are 'registered' tradesmen ?
TIA
