Business Rates Appeals – Frequently Asked Questions
Below are answers to the most common queries, including guidance on appeals, deadlines, eligibility, and key implications.
The deadline to submit an appeal to the Valuation Office Agency (VOA) is 31 March 2026. However, we strongly recommend not leaving it to the last minute as the process takes time and you'll need to gather supporting evidence.
It is sensible to seek advice if you have any concerns about whether your current rates are accurate. Situations that commonly justify a review include:
- Alterations or building works carried out since 2023
- Areas of your property that are temporarily out of use
- A lease agreement, rent review, or re-letting around 2021
- You believe your rates bill is excessive
Even if these do not apply, professional advice can provide reassurance and ensure you are not paying more than is necessary.
Savings vary case by case but can be substantial — often amounting to thousands of pounds — and may be backdated for up to three years.
If you miss this deadline, you'll lose the opportunity to challenge your current business rates assessment. This could mean missing out on thousands of pounds in potential rebates.
Whilst you can submit an appeal yourself, working with rating specialists can significantly improve your chances of success. Professional advisors understand the complex valuation process, know what evidence to present, and can handle negotiations on your behalf.
The appeals process can vary in length depending on the complexity of your case and the VOA's workload. This is why it's crucial to start the process well before the March 2026 deadline rather than leaving it to the last minute.
The type of evidence required depends on your grounds for appeal. This might include lease agreements, evidence of building works, floor plans showing unused areas, or comparable property valuations. A rating specialist can advise on the specific documentation needed for your case.
Allsop work on a contingency basis, meaning you only pay if the appeal is successful.

Business rates are changing in April 2026 - Rating Revaluation
A draft of the 2026 Rateable Values will soon be published, which is likely to affect your rates bill, for the next three years.
Broadly speaking your rateable value should reflect the rental value of your property on 1 April 2024. Your Business Rates are approximately 50% if your rateable value, so if you think that your rateable value may be calculated incorrectly then you can appeal.
