Update:
My electrician has been in and run a brand new ring main from the fuse box downstairs, fitted new sockets and tested everything. So far so good. Total wall outlets has doubled from 3 to 6 (it was effectively 2 sockets before as one was permanently connected to the boiler which now has it's own supply)
Now a minor setback - I have to replace all of the skirting boards
But I'm glad in one way - it means I can lay the floor first and run it wall to wall (leaving a small expansion gap) without having to worry about fitting to the existing skirting boards.
I've also just about finished the design stage of my new studio desk which I intend to start building when we get back from Gran Canaria (we fly on Monday for a whole 7 days!!)
Getting there slowly.........
