Confirm your property details
Source: gov.uk (2025-11-26)

You can confirm your property details or report any changes to them by submitting a check to the Valuation Office Agency (VOA)

The VOA updates the valuation of non-domestic properties every three years, known as a revaluation (https://www.gov.uk/introduction-to-business-rates/revaluation). Revaluation 2026 will come into effect on 1 April 2026. If you need to report changes to your current valuation, you must raise a check case by 31 March 2026. Changes you report to your current valuation will carry over to the 2026 valuation.

What is a Check case?

There are 2 parts to a property’s valuation:
- The factual details, such as the floor areas and number of rooms
- The value of them
If you want to challenge the value, you need to first agree the correct factual details with the VOA. This is called a ‘Check case’.

If all the information held by the VOA is correct

You must still send a Check case, even if the property details are correct, if you want to:
- tell the VOA about something affecting the land or property that’s not in your control (such as long-term disruptive roadworks)
- challenge the rateable value of the property
- change the address
- change the main use (description)
- change the date that a change occurred
Other changes you can report

You can also send a Check case to tell the VOA that:
- the property has been split into more than one
- the property has been merged with others to create one or more new properties
- the property has been demolished or renovated
- there has been a change in the local area affecting the property
- a court decision has affected the property
What to include in your Check case

The VOA will ask for documents to support your changes. Your evidence might include:
- photographs
- plans
- rent agreements
- a statement with extra information or comments that you have not included elsewhere
If you don’t provide any documents, your case may be delayed if the VOA need to ask you for anything.

You could be charged a penalty if you provide any incorrect information in your Check case. It could also lead to backdated increases to your business rates.

Submitting a check for a change in the local area of your property

The date you submit a check about something outside affecting your property (also known as a Material Change of Circumstances) can affect the outcome. If the issue is temporary, your check needs to be submitted while the issue is ongoing.

If you need to submit a check urgently for this reason and you’re waiting for your property claim to be approved, or you’re waiting to receive a copy of your detailed valuation and check form, you should email xxx@xxx.xx (mailto:xxx@xxx.xx) and ask for your request to be prioritised.

The subject line should be ‘Urgent: external Material Change of Circumstances’ and you should include the property address and your submission ID or reference number within the email.

After you submit a check

The VOA will review the details you send them. In most cases they will have enough information to process your check. However, they may contact you if they need more information.

If necessary, the VOA will update the property details and send you a written notification.

If you need to report any new changes after you’ve already submitted a check, you must complete another check. The VOA will review the information in the two checks and will contact you if there are any queries.
