Rateable Value Higher Than Your Rent? What to Check in 2026
If your rateable value is higher than your annual rent, it is sensible to investigate. The difference does not, on its own, prove that the assessment is wrong. A useful review compares the valuation with the property, the relevant rental market and the full terms of your letting.
This guide covers commercial premises in England and Wales under the 2026 rating list. It sets out a practical way to organise the evidence before deciding whether to raise a valuation case.
Why your rent and rateable value can differ
The 2026 rating list took effect on 1 April 2026 and uses a valuation date of 1 April 2024. Your lease may have been negotiated earlier or later, in a different market. Rateable value is an assessed rental value under rating rules, rather than a copy of the amount on your rent invoice.
Lease terms can also affect the comparison. Rent-free periods, stepped rents, repair obligations, landlord contributions and the extent of the property let all need to be understood. Not every payment labelled as rent represents a straightforward open-market letting of the assessed premises.
First, check that you are comparing the same property
Read the detailed valuation alongside your lease plan. Does the assessment include land, parking, an upper floor or a store that your rent excludes? Does it cover space occupied by another business? Conversely, does your rent cover several assessments together?
Write down the differences before comparing the totals. For example, a ground-floor lease and a valuation covering the whole building are not a like-for-like comparison.
Next, review the measurements and property description
Check the recorded floor areas against a measured plan.
Identify the use of each area: sales, treatment, office, workshop, storage or other accommodation.
Record which floors are included and how they are accessed.
Check separately identified items such as parking or air conditioning.
Note any physical changes and the date each occurred.
A measurement discrepancy should be supported by a clear plan and dimensions. A dispute about the valuation approach needs an explanation of why the adopted basis does not fit the property.
Build a rental evidence file
Keep the signed lease, any side letters, rent-review memoranda and evidence of incentives together. Add the letting particulars and the date the rent was agreed. If the transaction involved connected parties or unusual obligations, explain that rather than leaving it for the caseworker to discover.
Comparable properties are most useful when the differences can be explained. Look at location, size, floor layout, use, condition and transaction date. A nearby property with a lower assessment is a lead to investigate, not a complete valuation argument.
An illustrative review
Suppose a tenant pays £18,000 a year while the assessment shows £24,000. Those figures alone do not establish an appropriate replacement value. The review should establish when the rent was agreed, whether incentives applied and whether the lease and assessment cover the same space. Any proposed reduction then needs evidence and a reasoned valuation.
Separate a valuation issue from a billing issue
The council calculates and collects the bill; the Valuation Office maintains the assessment. If the rateable value is correctly recorded but relief, payments or occupation dates are wrong, the council account needs investigation. If the underlying property facts or valuation are wrong, the valuation process needs consideration.
A successful valuation review does not mean the bill falls by the same percentage. Multipliers, reliefs and the effective date also affect the amount payable. Continue paying the current bill while a case is considered, and keep any payment arrangement under review with the council.
