Apart from properties that are exempt from business rates, each non-domestic property has a rateable value which is set by the valuation officers of the Valuation Office Agency (VOA).

They draw up and maintain a full list of all rateable values, available at www.gov.uk/government/organisations/valuation-office-agency. The rateable value of your property is shown on the front of your bill.

Your rateable value isn’t the same as the rent you are paying on your property. It broadly represents the yearly rent the property could have been let for on the open market on a particular date. For the revaluation that came into effect on 1 April 2026, this date was set as 1 April 2024.

You can estimate your business rates by multiplying the rateable value by the correct ‘multiplier’ (an amount set by central government).

The valuation officer may alter the value if circumstances change. The ratepayer (and certain others who have an interest in the property) can request a change to the value shown in the list if they believe it is wrong, through the reformed Check, Challenge, Appeal (CCA) process. Full details on the CCA process are available from the VOA or from www.gov.uk.

The local authority works out the business rates bill by multiplying the rateable value of the property by the appropriate multiplier. From 2026 there are now five multipliers: the new retail, hospitality and leisure (RHL) multipliers have been set 5p below the relevant national multipliers for qualifying properties with rateable values below £500k, funded by a high-value multiplier 2.8p above the national standard multiplier for properties with rateable values of £500,000 and above.
 

The Non-Domestic Rating Multipliers for 2026/27 will be as follows:
•    Small business RHL multiplier: 38.2p
•    Small business non-domestic rating multiplier: 43.2p
•    Standard RHL multiplier: 43.0p
•    Standard non-domestic rating multiplier: 48.0p
•    High-value non-domestic rating multiplier: 50.8p
 

Every three years the Valuation Office Agency (VOA) updates the rateable values of all business and other non-domestic properties (properties that are not just private homes) in England and Wales. This is called a revaluation.   
At a revaluation, business rates bills may increase, decrease or stay the same. A rise in your rateable value does not necessarily mean your business rates bill will increase by a similar amount.  
Rateable values are the amount of rent a property could have been let for on a set valuation date. For the 2026 valuation, that date was 1 April 2024. 
We use these rateable values to calculate business rates bills. 
Revaluations are carried out to reflect changes in the property market, which means that business rates bills are based on more up-to-date information. 
 

Ratepayers do not have to be represented in discussions about their rateable value or their rates bill. You can manage your business rates yourself. If you want to appoint an agent, the VOA has published information about how to choose a business rates agent.

Please forward a copy of your lease/licence/agreement etc to nndr@milton-keynes.gov.uk. A bill will be sent out shortly afterwards to either the property address or contact address you have provided.

If you have purchased a commercial property, please forward a copy of the sale agreement.

We are responsible for anything to do with your business rates bill including adding any relief you might be eligible for. Please see our reliefs/exemptions page for further details.

The VOA is responsible for the valuation of your property. You will therefore need to contact the VOA for all queries about your rateable value. If you think your valuation is wrong or want to make any changes to your property details (such as floor area sizes and parking) you will need a business rates valuation account.

To appeal your rateable value, you first need to submit a check against your property on the Valuation Office website. You must continue to pay your business rates as normal until a decision has been made. Further information about the grounds on which appeals may be made and the process for doing so can be found on the government website. To contact the Valuation Office please use the online contact VOA service.

You do not usually have to pay business rates for home-based businesses if you:

• use a small part of your home for your business, for example if you use a bedroom as an office
• sell goods by post

You may need to pay business rates as well as council tax if:

• your property is part business and part domestic, for example if you live above your shop
• you sell goods or services to people who visit your property
• you employ other people to work at your property
• you’ve made changes to your home for your business, for example converted a garage to a hairdresser’s

If you have vacated your property please email the following information to nndr@milton-keynes.gov.uk

• Date trading ceased
• Date goods removed from the property
• Date the tenancy ends
• Your forwarding address so we can issue your closing bill.
  • If you are moving to another business premises in Milton Keynes, please forward a copy of your lease/licence/agreement etc.
• Name and address of your landlord

You may get a temporary reduction in your business rates if your premises are affected by severe local disruption (like flooding, building or roadworks).

You will need to report this disruption to the Valuation Office using the VOA service.
