Bear in mind that it takes a while for house sales to get registered
with the Land registry (months I think) for which you can't fault this
website.

Another new offering with the same service is at
http://www.nethouseprices.com/ - I haven't tried it but apparently it's
free for a limited period.

I've just tried it.
I checked my area, and it found absolutely nothing, but -
www.myhouseprice.com found the last 4 sales (one of which I had been
unaware of).
