I don't think its beyond the OP's scope to do this work, although perhaps he could qualify his qualifications, and perhaps cite them in his profile page.
Would appear your are doing this rewire in your own property, whilst yourself & family are living in the place?
What other works besides the rewire would take place, before, during & after the rewire?
Good advice from others. You have to doing the work, whilst still leaving it habital. As suggested some thinking, before starting work will be required to facilitate living in the place. Consider where your cable runs in voids will be, can they be done in a different place to existing. Planning the amount of cables that are likely to be in those runs, you'll only have so many joist to drill holes in.
You could consider running radial/RFC circuits and placement of outlets, and leave existing working until a particular point. I would be running my new final circuits as many as possible, but not energising. What thats done, only install and swop over your CU's. If the kitchen is being refurbished, run the cables to a particular point, then do the kitchen refurb, after that. Another thing I seen done is sockets done for one side of the property etc, as opposed each level or floor, so you still have existing sockets available.
Good luck.
