On 7th November 2024, the Valuation Office Agency (VOA) published details of a new duty on ratepayers, introduced as part of a broader reform to support more frequent property revaluations.
A key element of these changes is a new requirement for ratepayers to provide timely and accurate information about their properties to the VOA. This duty will be piloted from 1st April 2026 with a small group of ratepayers, ahead of full implementation from 1st April 2029.
From the 1st April 2029, all ratepayers will be required to notify the VOA within 60 days of any relevant changes to their property. These include changes to the occupier, lease terms, rental agreements, or physical alterations to the property itself. This is a self-assessment for business rates and occupiers who will have to declare what is missing from the assessment, such as:
The new duty will replace several existing ratepayer obligations, streamlining the process and reducing administrative burden. This includes the removal of Forms of Return, which are often lengthy and time-consuming, and the Check stage of the VOA’s current Check, Challenge and Appeal (CCA) process.
Instead, ratepayers will be required to notify the VOA via an online portal within 60 days of key events such as rent reviews, lease renewals, or new lettings.
Importantly, this obligation applies to all ratepayers, including those currently benefiting from small business rate relief. In addition, ratepayers will be asked to confirm annually that they have reported any relevant changes to their property.
Compliance will be managed through a new digital service, designed to simplify reporting and improve transparency.
When a property is vacated or occupied under the 2029 List, ratepayers will be required to notify the VOA directly, rather than the local council, as is currently the case. The VOA will then update the portal and inform the relevant local authority on your behalf.
The new duty introduces strict penalties for failure to comply or for providing inaccurate information. Ratepayers should be aware of the following:
These measures are designed to ensure that property assessments accurately reflect reality. If the current valuation is outdated or incomplete, the 2029 List will correct it – potentially resulting in significant increases in rates payable.
As part of the wider reforms, the VOA will begin sharing more detailed information about how property valuations are determined.
This increased transparency will support more informed decision-making, particularly around appeals. With the new duty requiring notification of changes within 60 days, the VOA will have up-to-date information on aspects such as lease terms, rental values, and physical alterations.
