one of the most challenging parts of the coc is the roof space.
some people say the roof space is now regarded as a junction box?
i believe that if any other services are in a space be it a roof or the like every precaution should be taken to prevent these other services being affected by dangerous wiring...especially considering you are normall y sweating like a pig up there...sometimes flat on your stomach trying to work in arkward positions....whoever came up with that ruling must be an office clown who has never had to work in a roof
the other issue i have when doing inspections are the wires between the pipe and light fitting...when do you declare it as open wiring...all connections should be done in a junction box then one wire should be taken to the light being a piece of 3 core silicon.
wiring conected in tee boxes...eesh i see this a lot in old houses.
and as for 12 volt downlights and transformers...i think a new thread will be required.
insurance companies should be a lot more strict with payouts...like if you have a smooth tyre no claim they should clamp down on electrical installtions...if not up to standard no insurance cover...this would also help to improve the electrical industry...and root out illegal fly by nights...it is found that a n unregistered person works on an instalation no claim...it will also force the public to become more aware of things like the coc and keep the copy in a safe place....like they do their vehicle log book...with all records of work done on the installtion after a coc is issued.
i dont know why they dont already do it...maybe ther eis something i am missing because surely they would save lots of money in payouts.
i have been requested to carry out thermal inspections by insurance comapnies but never a coc.
