Some other tips
remember to get your post forwarded and bear in mind it takes 7 days or so to go live, that way you won't be in a mad panic to change the address on everything and can do it after you moved
Also ring the gas and elecctric now and get your accounts sorted with them, don't depend on the vendor to do it and don't wait until after you've moved in(specify the go live date). Gas in particuler have been known to lock a meter that was no transferred over in time
Big clear out needed and be ruthless. if you can afford a removal company then do so, but shop around. If you are moving bit by bit, make sure the insurance in the new house is sorted first.
Try and paint before you move in, makes life so much easier
and above all, be prepared, relax and enjoy it and get someone to mind the smallies for a day or so
