My understanding of the regs is that you must have a separate earth
arrangement for the garage and not connect the earth through the supply
cable from the house.Screwfix do a small garage consumer unit (c£29) and
earth rod.Try and estimate what current you will draw from garage sockets to
ensure you get correct cable size and no more than 4% voltage drop when
fully loaded.

Hi Gents
Thanks for all your suggestions - very useful. I meant to suggest
an RCD, and was wondering about using a separate earth, so your
replies are spot on for me.

Thanks again
