7 Mistakes You're Making with Your Business Rates Appeal (and How to Fix Them)

The 2026 business rates revaluation is now in full effect. For many UK SMEs, the arrival of a new rating list brings uncertainty and financial pressure. You may have noticed your rateable value has shifted, or perhaps your bill has increased significantly despite no changes to your premises.

At CheckMyRates, we see business owners making the same errors during the appeal process. These mistakes lead to rejected challenges, missed savings, and unnecessary frustration. We believe in providing clarity and control over your essential expenses. We do not push for supplier switches. We do not have hidden agendas. We simply confirm if your charges are accurate.

If you are considering a business rates appeal, avoid these seven common pitfalls.

1. Accepting VOA Measurements as Gospel

Many business owners assume the Valuation Office Agency (VOA) has perfect data. They do not. The VOA often relies on historic information, partial records, or outdated building plans. A single error in floor area measurement can inflate your rateable value for years.

We find that discrepancies in area, use type, or layout are remarkably common. You should not assume the figures on your bill reflect the physical reality of your building. We validate these details through evidence-led reviews. If the measurements are wrong, your valuation is wrong. It is that simple.

2. Confusing 'High Bills' with 'Incorrect Valuations'

This is a fundamental mistake. The VOA does not care if your bill is difficult to pay. They only care if the rateable value, the estimated annual rent of your property at the valuation date, is correct.

Appeals based on "affordability" or "fairness" are almost always rejected. To succeed with business rates help, you must focus on the valuation basis. You need to prove that the rental evidence used by the VOA does not align with market reality. We provide the objective evidence required to make that case. We don't start with assumptions; we start with data.

3. The "Set and Forget" Mentality

The 2023 Rating List closed on 31 March 2026. Many businesses believe that because that window has shut, they must simply accept their new 2026 valuation. This is incorrect.

While you can no longer challenge the 2023 list, the 2026 list is now your primary focus. However, the logic used in previous years often carries over. If you didn't fix an error in 2023, it is likely still there in 2026. We help you identify these legacy errors early in the new cycle. Waiting until the end of the list period is a mistake that costs money every month.

4. Overlooking Local Authority Reliefs

A business rates appeal is about the valuation, but your final bill is also affected by reliefs. Many SMEs miss out on Small Business Rates Relief (SBRR), retail, hospitality and leisure relief, or transitional relief.

Your local authority administers these, not the VOA. We identify if you are eligible for these reliefs and ensure they are applied correctly. We don't just look at the headline figure; we look at every line of your bill to ensure you aren't losing money to administrative oversight.

5. Submitting Weak or Misdirected Evidence

The "Check, Challenge, Appeal" (CCA) process is rigorous. The VOA expects professional-grade evidence. Vague assertions that your rates are "too high" will not result in a reduction.

You need robust supporting data:

• Professional floor plans or surveys.

• Photographic evidence of property condition or access constraints.

• Comparable property data showing lower market valuations.

• Current lease and rent details that contradict the VOA assessment.

We focus on "proportionate" and "confirmed" evidence. We provide the technical backing that gives your challenge the best chance of success.

6. Trusting "No-Win, No-Fee" Sharks

The business rates specialist industry is unfortunately populated by firms with hidden agendas. These companies often use aggressive marketing to promise massive savings. They may lock you into long-term contracts with unfair uplifts or hidden fees.

We are different. We are independent and objective. We don't take a cut of your "savings" in a way that incentivises us to make risky or speculative claims. We simply charge for the audit and provide the evidence. We tell you the truth: even if the truth is that your bill is actually correct. Our goal is clarity, not a quick win.

7. Ignoring Material Changes of Circumstance (MCC)

Your rateable value is not static. If something physical changes in your area, you may be entitled to a temporary or permanent reduction.

Common MCCs include:

• Major roadworks outside your premises.

• Nearby construction causing significant disruption.

• Flooding or structural damage.

• Changes in the use of neighbouring properties.

Many businesses fail to report these changes. We monitor these factors to ensure your rates reflect your current operational reality.
