I am also an electronics engineer, have been a sucessful one for over 40 years.
And therefore I know the difference between a circuit diagram and the installation diagram needed for converting that drawn circuit into a safe working reality.

When you said 'i'm currently converting......' I thought that meant the job was in progress, as opposed to being just theory...
Sorry, wasn't meant to be rude, but it is a situation that a lot of DIYers find themselves in. I certainly don't blame you for not being aware of notification requirements of Part P, not many people do. That doesn't mean you don't have to consider it.
A sparky can only certify work which he has done. Also, he can only notify work which he has done.
I doubt a circuit diagram will have any bearing here, the circuits involved are simple. Its more to do with how and where those cables are to be installed. This would be far easier to deal with be inviting a sparky to you house to discuss your proposal.
Aberdeen was up north of the border last time I checked hence part p doesn't apply.
What sort of electronic equipment will you be repairing? Is there access to live parts at mains potential? If so I'd really consider having some sort of isolation transformer in there.

Hiya, no.. its all max 5v

oops, missed the Scotland bit. 
I wouldn't expect him to either, as he lives in scotland.
Although I think you would need a building warrant for this work, as it's in a flat.

How do you square connecting a 2.5 RF circuit to a 6mm incoming feed?
Does that comply?
Does that comply?
I can see no problem with that provided the feed to the 6mm was fed via over current protection suited to the 2.5mm part of the circuit.
It should comply unless the regulations specifically ban the use of oversized cables as part or all of a circuit.
I can't see anything that specifiy does not allow a 'lollypop' circuit, does make testing a little more troublesome though, and if the connection point is someway from the board it might be difficult to see whats going on at a later date after records have been lost.
Other points to note, are it'll have a higher zs than a ring final right back to the DB and does not meet requirements for high integrity earthing (should that be a requirement).
I've often seen them chucked into computer labs with little deisgn, to give a 32A DP isolation switch for night time shutdown, no HIE, and because of the inrush of the switchmode PSUs, the breaker has often been swapped out for a D32 and the measured zs is somewhere approaching twice the max allowed

Comply with what ? The regs only tell us what minimum levels of safety should be achieved. A 'non-standard' circuit is still safe if it meets all the necessary parameters
