part p only required for new circuits in special locations ie outside areas, kitchens, and bathroom, and i dought the panel will be installed in a bathroom

What about an airing cupboard within a bathroom - special location?

no wont trip a lighting circuit but the ring main may well be covered by an rcd Earth leakage device, now RCDs are prone to tripping on earth faults correct, so if the pond or outdoor sockets trip sai rcd while on holiday then the same situation arrises, dedicated circuit every time on an MCB not an rcd installed within regs to comply with that cable not been buried in a wall.

Fair comment mate. What would you do then if the customer has had a standard dual RCD board fitted that has no unprotected ways. RCD's cause no end of trouble. You could also the fact that the dead (or dying) alarm will alert someone of the defrosting fridge freezer, lol.

if its a dual rcd board then there is a 50/50 chance tyhat the other rcd will trip, but me i usually install a split load with 2 rcds and 3 ways un protected for security and smoke alarms

I was talking about the BC type plug in dusk to dawn or random light-that plugs directly into the light fitting!

Doesn't answer the question though does it?
