About Non-domestic Valuation

Non domestic property in Northern Ireland is assessed on the basis of its rental value (known as the net annual value or NAV). The current valuation list for non domestic properties became operative on 1 April 2015 and is based on rental values as at 1 April 2013.

Each non domestic property has been valued in line with comparable properties in its locality.

Some non domestic properties require specialist assessment to reflect their particular characteristics eg. schools, licensed premises, petrol filling stations, sporting facilities. The valuation of such properties involves the application of specialised methods of assessment, which may involve examination of the property's receipts and expenditure, or its estimated replacement costs.

You can find your NAV on your rate bill or you can use the link below to check the NAV of individual non domestic properties. You can also use this link to make an online application to have your valuation reviewed if you feel that your NAV is not correct.

To make an application, you should input your property details on the first page and click on the search button. This will then bring up the address and valuation details of the property. You can then click on the submit query button and follow the instructions on the following pages.
