Don't forget to bond the pipe...
The way I do it is to drill a 20mm hole through the wall then waggle the drill about so you can fit a length of 20mm plastic tube through. 2.5mm twin and earth and check the termination is secure in the house socket as three into one can be easy to leave one loose.
A good blob of silicone sealer round the back of the outside socket to keep the rats out!
