all you are doing is adding a 16a socket, nothing big or fancy.
i would run the cable in 2.5mm SWA for protection and stick a 16a plug on the end, put a 16a waterproof socket on the side of the house and run the supply back in 2.5mm twin and earth to a new breaker on the consumer unit. job jobbed.
just make sure you aren't overloading the consumer unit and its rcd protected.
