Understanding summary valuations
Every five years the rateable values of all 1.75 million business properties in Wales and England are reassessed. The most recent revaluation came into effect on 1 April 2005. Many ratepayers received details of their proposed new rateable value in the form of a summary valuation.
Renting out your home
If you rent out your home for other people to live in, the property will normally be treated as domestic. Council tax is therefore payable and business rates will not apply. Talk to your local Valuation Office if you are in any doubt.
