Hello experts,
I'm putting together an energy monitoring system for a social housing application and need a mains socket inside an enclosure.
One enclosure sits next to the consumer unit for monitoring electricity use. I need to plug this specific transformer into it to power the system and obtain an AC voltage sample:

Another enclosure sits in the airing cupboard (electric immersion heating thermal store) and I'll be plugging a generic USB charger into it to power that system. Logistically it's easiest if the landlord installs the enclosures and sockets with their qualified trades, we bung our gear in the box, and hopefully nobody, including the tenants, touches it for the next 6 months.
Q1) Any rules against a socket inside an enclosure that requires a screwdriver for access?
Q2a) We don't want to add circuits. Can one add a socket (on a 1.5 mm^2 T&E running in conduit) to a lighting circuit at the consumer unit, provided that this socket is within that enclosure, labelled as to its specific use and the circuit it's fed from, and not accessible without a screwdriver. Maximum load <5W.
Q2b) Same question but in 2.5mm^2 T&E on the end of an immersion heater circuit in the airing cupboard, again inside a screwed shut enclosure.
I'd like a solution that a qualified electrician can wire in our absence with a clean conscience and we can arrive to plug our gear into later.
Thanks,
