They are in a kitchen in a building which is not domestic, so nothing to do with Part P. However likely would be covered by health and safety at work, but often there is a procedure that needs to be followed, like the handyman has to raise the report for an electrician to be called.
However main thing is watch your own back, so MUST be reported in writing, it can be a text message, or written on fag packet, but all health and safety reports must be in writing, and it the HSE find you knew about a fault and did not report in writing you could find yourself in court.
There is no requirement for labels saying inspected and tested, it must be written down, but tested all items in office number 5 will comply, in the main the labels help us the electrician to ensure we don't retest the same item many times.
What the BS 7671 regulations say are not law, but may be used in a court of law to show reasonable care not taken, and this phrase reasonable care means that things do not need to be perfect, but the rules have caught me out from time to time, we try to comply, and some times it seems what ever we do, it's not right.
But in many cases it is a paperwork exercise, I have been called on the phone in a noisy environment and only managed to work out some thing wrong in Unit 5, so visit Unit 5, see the manager, who has no idea what the fault it, so I write in the book visited Unit 5 no fault found, no report of fault in book. I am sure you can see the problem, there was a fault, but since not written down, I have no idea what the fault was. Then some one is injured, and some one spouts out, I did call the electrician, so next question is where did you write down the problem.
There is no requirement for items to be fixed, I have used items with 63 amp plugs and sockets using more power than a normal house, 5 years is maximum time between inspection and testing, but in the main it is a lot shorter, I have worked where 3 months between inspections, often the firm will lay down rules, like PAT testing labels on everything, and also training for personal, I remember attending one of these, and the safety officer told us all how labels must be on every electrical appliance, if not it must be unplugged and returned to stores, so I said are you sure, he said yes, so should I start now, yes he says, that was until I started unplugging the computer lead sets as they had no labels in the office we were being taught in. Well only unplugged one, and said with lead in hand, shall I continue.
And this is the point, the computers had clearly been tested with the lead, but the guy testing had only written out one label, some times we need to use some common sense. Some oil spilt on the floor, do you write out a report, or use that paper to simply wipe up the oil.
