What legislation is that? I would lock off and bugger off; I'd argue preventing injury or death trump's inconvenience of no power..
The HSE are quite strong insisting all in writing, I have had it, radio call **** **** **** unit 5, all I got was unit 5 so off I went to unit 5, talked to supervisor and he said I have not called you, so returned with the thought if important they will call again.
Well it seems an extension lead had been damaged, some one did get a shock, so standard procedure sent to hospital, standard procedure HSE informed, they arrived, and looked through records, no report of damage, so then questioned work force, and one came forward with I saw the damage and I told the electrician, first question was how, answer on radio, next question did you complete a report sheet, answer no, result she was fined.
As to housing acts and not leaving a home uninhabitable not sure of the law, think it was designed to stop landlords using a fault as an excuse to evict, but does not matter if fireman, gasman, electrician or any other tradesman, if you make the house uninhabitable you have to find some alternative accommodation, be it phone council social services, or local hotel, or just be told by the occupants it's OK I can go to mothers. But what you can't do is turn off the water and say tough, or electric or gas if they are needed to make it inhabitable.
I am sure at some point we all have, problem with cooker supply, and owner says it's OK I can get a take away tonight, but we shouldn't, neither should we break the speed limit, but many do.
I have however been called to a home where the electrician has said sorry I must go, and run off without completing the job, his wife worked in a pub, and it was his duty to look after the baby was his excuse. Clearly there will be a point where we all have to say, sorry can't fix it tonight, but then we need to find the alternative accommodation.
But I know I have worked until well past midnight when it all went wrong, that's part of the job, can't simply say tough.
