Business rates represent a major property overhead for occupiers of commercial property.

But how do business rates work, what is Revaluation, and how does it affect occupiers of commercial property? Adam Barnfield, Head of Business Rates at Vail Williams, explores.

Business rates is a property tax and Revaluation is a key process which determines how much you pay, as an occupier of commercial premises.

What is Revaluation?

Revaluation is the periodic reassessment of the Rateable Value (RV) of commercial properties to reflect changes in the property market.

The rateable value of a property is based on its estimated rental value on a specific “antecedent valuation date” (AVD).

Conducted every three years, revaluation updates the rateable value (RV) of commercial properties to reflect changes in the rental market.

This process is carried out by the Valuation Office Agency (VOA) in England and Wales, the Scottish Assessors Association (SAA) in Scotland, and the Land and Property Services (LPS) in Northern Ireland.

The latest revaluation took effect in April 2023, using rental values from April 2021. The next revaluation is due in April 2026.

How does Revaluation impact you as an occupier?

Revaluations supposedly ensure that business rates remain fair by redistributing the tax burden in line with market fluctuations.

Some areas or sectors may see their business rates increase, while others may benefit from reductions.

Your business rates bill may change

If rental values in your area have increased since the last revaluation, your RV may rise, resulting in a higher business rates bill. This will almost certainly be the case for high street traders this revaluation.

However, if rents have fallen, you could see a reduction in your business rates.

Sector-specific effects

Retail, hospitality, and office spaces have been particularly affected by changing demand post-pandemic, with some occupiers seeing reductions in RV.

Industrial and logistics properties, where demand surged throughout the pandemic, have faced significant increases in business rates.

Transitional Relief may apply

The government provides Transitional Relief to phase in large increases or decreases in business rates over time, preventing sudden financial shocks, however, the reality is that the financial burden is still felt – particularly on the already ailing UK high street.

Some businesses may also qualify for Small Business Rate Relief or other support measures.

Revaluation doesn’t always mean higher costs

While revaluation redistributes the tax burden, it doesn’t necessarily increase overall business rates revenue—the government adjusts the Uniform Business Rate (UBR) multiplier to maintain balance.

However, changes in relief schemes and policy decisions can affect how much you pay.
