Meleri, I think that Scotland was the first country in the UK to have the Council Tax reassessed and this was followed by Wales not long after.
I think that the Wales banding was based on the value of the property in 1993 but I'm not positive about the year. I remember in 2005 our house was uprated one band and I had one heck of a ding dong with an unpleasant guy in the Valuation Office. I won the case and our house was then reinstated to our previous banding.
My understanding now from talking to people who have just brought property in the area is that the new purchase price of the property reflects the Banding rate
What I don't know and must find out if England was also rebanded in the same way as Wales and Scotland were.
After I posted the above I checked the Council Tax banding for England and copied it below. It doesn't look like England has been rebanded but of course I could be wrong. A definite vote loser for whoever tries to implement it in England
Properties in England are put into one of eight bands (A-H), depending on the price they would have sold for in April 1991.
The valuation band ranges for England are as follows:
