What size armoured cable to shed

I was thinking of supplying electricity to light up the shed that will obviously require a switch , two double sockets to use a small electric convector heater or plug in an electric drill or saw and a radio. What size armoured cable will I need and all the other components to get this done. I am having a kitchen extension so that would be the perfect time as the cable can be fitted whilst accessibility will be easy.

"2.5 mm cable fused at 20 amps would cover what you list. Best if it is wired direct from your fuse
Board. You should have a two way fuse board IN the shed 6 amp way for a light and a 16 amp way for the sockets. There should also be 30 mA RCD in the shed plus an earth rod to provide earthing protection for the shed. The shed earthing should not be linked to the house earthing

"Would need to know more information.
Length from the point in the house where the supply will be taken ( ideally your consumer unit) to the shed.
Kw of the heater would help also.

"There are other factors, like distance and diversity to recommend the required diameter of the cable. 6 mm or 10 mm.."
