Is there any electrical standards I can refer to regarding a house built
in Scotland in 1999 and the use of standard interior lights for an
outdoor porch exposed to the elements? These are downlighters and it
seems like poor design

Also anything covering the wiring of interior lights where the light is
in a top floor - ie the wiring runs through the roof cavity. An engineer
has said that the wiring needs joint boxes for waterproofing and also
earthing requirements

thanks
