For many businesses across the UK, business rates are simply a line item on their overheads, paid with little thought, rarely questioned and almost never challenged. But behind that seemingly fixed figure is a complex system filled with calculations, multipliers, exemptions and, too often, mistakes.
At Dunlop Heywood, we’ve helped clients across sectors reclaim substantial sums through a process that many still aren’t aware exists.
What is a Rating Audit?
A rating audit is a forensic review of your business rates bill, not just the rateable value, but everything surrounding it. That includes reliefs, exemptions, transitional arrangements and how the billing authority has calculated your liability. It’s a back-to-basics review of what you're paying, why you're paying it and whether it’s correct.
Unlike a rating appeal (which challenges the valuation of the property), a rating audit focuses on billing accuracy and entitlements. It looks for missed opportunities and administrative oversights that could be costing your business money, sometimes over many years.
Why Audits Matter: Real-World Errors We See Often
You might be surprised at how often we find costly errors hiding in plain sight. Here are just a few examples we regularly uncover:
- Missed Small Business Rate Relief (SBRR): Especially common when businesses expand or change premises.
- Incorrect application of transitional relief: Missteps in how changes between rating lists are phased in.
- Ineligible charges: Charges levied on spaces that should be exempt or de minimis.
- Wrong property classification: Errors in how the VOA categories your premises, affecting the rateable value.
- Failure to apply available reliefs: From retail discounts to empty property relief, many businesses simply don’t know what they’re entitled to.
- Retail, hospitality and leisure relief is tapering off and will disappear by April 2026.
- Charitable relief has been removed for private schools.
- A new five-tier multiplier system is replacing the traditional small/standard split.
- Thorough: We review all aspects of your liability across all properties.
- Strategic: We advise on where reliefs may apply or can be backdated.
- Efficient: We liaise directly with billing authorities to correct any errors or omissions.
