I rang BCO and asked whether I could do the install myself, they knew I wasn't qualified, and they said yes, but I would have to have the electrician who works for the council come out and certify, which costs £360, which seemed fine given the few prices I'd had for other jobs.
MikeGT the members having given advice here, have justifiable concerns over your ability to carry out this work safely and correctly. Unlike plastering, plumbing of water systems etc, electricity is obviously potentially dangerous to the installer and end user, as opposed to poor quality workmanship or water damage. As you have no experience or even practical skills as an electrician, a project of even this size, could put you or your family members at risk.
I'm a member of avforums, where members there undertake similar projects, for cinema rooms or even show casing whole house renovations. Most are sensible or perhaps realistic & recognise their limitations, and use the appropriate trades and carry out some of the easy take themselves. As a young man, I use to service my own vehicles, now days I leave that to persons who have the skills, knowledge & tools to carry out the work safely & correctly, I want my brakes to work when I need them.
If you are determined to go ahead with this, you should speak in depth with your LBC, to see how the installation would be inspected & tested as you proceed, for example the hole for footings has to be inspected & approved by LBC, before the concrete is poured. In my experience LBC, have little dealings & experience with people carry out their own DIY electrical installation, so the process might not be straightforward.
