As the 2026 Rating List approaches, Local Authorities are increasingly focused on ensuring that non-domestic properties are accurately reflected in the rating list within the required statutory timeframes.
Maximising backdated liability where permissible, is central to protecting long-term revenue and maintaining rating list integrity. The ability to secure this liability depends not only on the timing of referrals to the Valuation Office Agency (VOA), but also on compliance with BAR Submission Standards to ensure amendments can be processed efficiently.
Several key dates define the current cycle:
- 1 April 2026 marks the start of the 2026 Rating List, after which opportunities to secure backdated liability for the 2023 List become increasingly time sensitive.
- 30 September 2026 is the VOA guidance date for submitting cases intended to support backdated liability.
- 31 March 2027 marks the deadline for changes to be made to the 2023 Rating List.
Together these dates highlight a narrowing window for identifying, progressing and evidencing cases where retrospective liability may apply.
Collectively, these milestones signal a narrowing window for identifying, evidencing and progressing cases where retrospective liability may apply.
Experience from previous list transitions demonstrates the importance of early referral. Competing pressures including draft list preparation, legislative changes, relief amendments and ongoing Check, Challenge, Appeal activity significantly increase workload across the cycle. Delays at earlier stages can therefore have material financial consequences.
For Analyse Local identified cases alone, approximately £29.2 million in additional rateable value did not make it onto the previous rating list in time, contributing to £38.2 million in associated yield that could not be secured through backdated liability.
By focusing on early review and structured case management, Local Authorities are better placed to manage risk and support the accuracy of the rating list within the permitted timeframes.
Preparing for the 2026 Rating List and looking ahead
As attention turns to the 2026 Rating List, the period between list publication and statutory deadlines will be critical.
Tools such as Maximise Business are designed to support this process, assisting local authorities to identify potential Material change in circumstances (MCCs) to maximise revenue retention.
