To expand on what everybody ese is saying....
If you are rewiring your house it must be done by a 'competent person' i.e. a qualified electrician. This electrician MUST be part of a part P organisation OR must notify the work to building control directly and pay their fee. This is because a rewire is notifiable work, and it would be ILLEGAL to carry out the work without notification in one-way-or-another to LABC.
On top of this, the work would need to be cerificated to say it complies with BS:7671 and that would include a full test of circuits. This must be done with equipment usually costing in excess of £500. As a self-confessed DIYer I doubt you have this equipment or knowledge or how to use it. Neither, I would imagine, would you have knowledge about the various earthing systems, bonding, the adabiatic equation, cable capacities, the difference between a ring and a radial, loop in-loop out, 2 way and intermediate switching......
DO NOT rewire your own home. You will eventually run into problems. A few could be; Things don't work properly and you don't know why; You have problems selling your house; You get sued by your local LABC; Your untested wiring causes a fire, your house burns down and you, your family and your goldfish die. If something's worth doing, do it right. Get a Part P registered electrician in to do it properly.
