Mike Harris is not registered with a competent person electrical scheme, but filled out the electrical certificates and I paid him on that basis. It later transpired that these are invalid, and I've now asked him to send someone that is registered with a competent person scheme and can provide a valid certificate. Mike also failed to tell me that the building inspector told him that the glass in the double glazed unit had to be toughened glass, and in fact told me that the inspector had said the window was fine. Mike also boxed in my electric and gas meters as part of a garage conversion, the door was held on my magnetic catches and was impossibly heavy for one person to lift, when I tried to open the cupboard for the first time the door fell off completely, hit my leg and cracked the newly laid wooden floor. I now have a huge bruise. Mike laid a wooden top click floor which has been left with large gaps and chips of wood missing where it has been badly fitted - it was not a cheap floor. The window sill is very badly constructed with one section of the window sill higher than the other, and a large gap in the middle.
