Working from home, renting out a holiday home or providing bed and breakfast - you may have to pay business rates on your property
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.
My bill is wrong
If you think your rates bill is wrong for any reason, you should contact your local authority immediately, so they can explain how they have calculated it. The details are on your bill. It is important that you keep up your payments in the meantime.
