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.
Changing or diversifying your business
Diversifying your business, or changing what it is you actually do, can affect your rateable value. For instance, if a factory producing goods has part of the building converted to an on-site retail outlet selling those goods, the business has diversified in its nature and there may well be a corresponding change in the rateable value.
If you are thinking of diversifying your business and want to find out how this may affect your rateable value you should contact your local Valuation Office, who will be able to advise you.
