Hi ceabhail,
This project comes under Part P of the buildings regs and legally needs to comply. You need quailfied part p electrician, See Docs projects on Part P.

Because of the nature of the work ,the work will need to conform to part p of the building regs.
If you are diy you will need to notify building control before you start and then get checked after,which will cost you, if you dont know the relevent regs and do it wrong you will have to redo it, it would then proberly have been easier to get a part p elect in the first place, who can do the work straight away and let him worry about the paperwork.
It is your choice.
If you get an elect make sure that he will give you relevant paperwork.

Looking at cable size I would expect no you can't. Sorry to say this but 2.5mm can normally only power two sockets. As the other have said Part P does require a load of paper work and testing and at about £700 for the test gear it would be cheaper to get someone in than DIY. I theory do can still do DIY but in real terms the only people who could both do the job and correctly fill in and submit the paper work are electricians.
