I already have an outside brick built shed/coal shed, just big enough to hold 4 bikes and a lawnmower, with its own consumer unit coming from the house so am hoping they put a junction box before that unit and run the new armoured cable from there and into a new consumer unit in the summerhouse.

Blimey Arfermo you running an illegal cultivation system with that many sockets and lights! Agree no matter where you put them or how many it's never enough or in the right place so don't skimp on that aspect. Is the shed insulated? Might want to do that as part of your plan and consider the heating you will need as that can influence decisions.
