Scotland does have different rules in part. However in England a minor works certificate should be issued even for a lamp change. This doesn't happen in the wild. If you can find an electrician willing to charge you for the time and effort to do the paperwork that's great.
Cheers, spoke to the contractor and he says it's never done under a minor works cert as it takes low voltage power from an existing installation, or something to that effect.
