Property changes and business rates
How making alterations to your property or the type of business you use them for can affect your business rates.
Businesses occupying non-domestic properties pay business rates. The amount of business rates payable is calculated using the rateable value and the multiplier, set by the government. Different multipliers are used for Northern Ireland, England, Wales, and Scotland.
If you change the nature of your business or make alterations to your property, for example, adding an extension and increasing the rental value, this may then affect the rateable value of your commercial property. This in turn may affect the amount of business rates you are liable to pay. You should inform Land & Property Services (LPS) if you make changes to your existing property or business to ensure you are paying the correct amount.
This guide explains if you need to pay business rates for your property and how changing or diversifying your business can affect the rateable value of your property. It explains what to do if you are moving to new or additional property and where to find further information and advice.

Rateable values for business rates
Premises that are subject to business rates are given a rateable value. Rateable values can be amended at any time to take account of physical changes to the property. All rateable values are reviewed at General Revaluations to take account of the current economic climate. LPS completed a revaluation for non-domestic properties in Northern Ireland on 1 October 2021. The rateable value is based on the likely annual rent for the premises if they had been let on the open market from 1 October 2021. .
The business rates you are charged in Northern Ireland are calculated using the rateable value and the poundage rate (the regional rate plus the district council rate). See how business rates are calculated.

Business rates: changes to your existing property or business
Property or business changes that might affect your rateable value and what to do if you think your rateable value is wrong.
The rateable value of a business property is based on its open market rental value at a set date. Changing your business premises can affect the rental value and so affect the rateable value. For example, the rateable value might increase if you build an extension, install air conditioning, or upgrade the property in some way. Changing what you do or diversifying your business can also affect the rateable value of your property. For example, if you start using part of your premises as a shop - instead of as a warehouse - the rental value might increase
