If you want to tart the place up for a couple of years then move on, then it might be worth selectively ungrading the electrics as suggested, in which case, the price might be a bit high, but i don't know the going rate for Berkshire. Its not really a fair comparison for a spark from another part of the country to say its too much/not enough. I would suggest that you get a couple more quotes to get a better idea.
However, if you plan to settle in the home for years to come, then you may well be in possession of the house at somepoint in future when it does want a rewire. If you wait until then, the re-wire won't cost you any less than it will now, but it will be far more inconvienient to have the work done.
If you consider that the cost of a part rewire + a PIR may take you (give or take a few quid) to the price of a complete rewire anyway it may just be prudent to bite the bullet and do it now. Its off the list of jobs for 50+years and you get piece of mind.
