Non Domestic Rates (NDR) are also known as Business Rates and are a property tax paid by non domestic properties.
They are the means by which businesses and other users of non- domestic property contribute towards the costs of local authority services. The Welsh Governments web site, see link, covers this area in detail. This includes specific information on pubs and self-catering properties.
Follow the Business Wales link and click on Tax from the menu bar on the left. Then click Business Rates from the main list.
