Sky engineer drilled the wall to fit an eye about 5 feet from the ground to secure his ladder to, I offered to foot the ladder (at the time I was a fireman) however he refused my help as if he fell he would not be insured, H&S gone mad!!! My daughter had sky fitted the engineer made a complete mess of routing the phone cable over a radiator and believe it or not up around her fire surround nail cable clips actually to the surround, needless to say she complained, another engineer came re-routed the cable and sky eventually gave her a sum of money to have the damaged surround replaced. Make sure your around when they install, just incase.
