Simply Build It

you need to speak to an electrician first. As you appear to be aware this is notifiable under part P, but very few electricians will sign of work that they haven't done, and you need to ensure it meets his requirements so he will sign it off rather than tell you to pull it all out and start again!

If you have pal who can sign it off that's great and he should be able to give you guidance on the installation as certain requirements need to be complied to.
As for having an electrician that is unknown to you signing it off, not sure about that as they then take the responsibility or that installation and maybe not be willing to that.
So other than that you need to notify your local building controls of the work you are carrying out and they will then visit on first and second fix.
Look on project pages for info on part p of build regs
and google "competentperson.co.uk"
But the answer to your question is that the cable suppling Line and Neutral to you shed will also contain a conductor called CPC (circuit protective conductor)
These conductors; Line, Neutral and CPC would normally be terminated between shed Consumer Unit and your house consumer unit, which is where it will pick up the earth connection from.
Any querries don't hesitate to reply.

Thanks for replying promptly, a friend of mine is a registered sparkie who is willing to let me do most of the work ( under his supervision so to speak)
