Business Rates Revaluation Advice for Accountants and Property Professionals

Direct answer: accountants and property professionals should treat a business rates revaluation as both a valuation and cash-flow review. Compare the new rateable value and property facts with the client's lease, occupation and plans, then separate VOA valuation questions from council billing, relief and liability issues.

Where professional reviews add value

A change in rateable value does not translate directly into the same percentage change in the bill because multipliers, transitional arrangements and reliefs can affect liability. The first task is to reconcile the property record and bill, identify material changes and flag issues requiring specialist rating or legal advice.

Practical example

An accountant preparing forecasts sees a large increase for a client's office. The VOA record also includes a floor that the client surrendered. Before treating the entire increase as a revaluation effect, the adviser gathers the lease variation, plans, bills and rating details and refers the factual discrepancy for review.

Documents and evidence checklist

• Current and previous business rates bills.

• Current and previous rating-list entries.

• VOA valuation details and floor areas.

• Lease, rent review and occupation documents.

• Plans and details of physical alterations.

• Relief decisions and transitional calculations.

• A client timeline covering acquisitions, disposals and empty periods.

What to do next

Build a repeatable review checklist for every property-owning or occupying client. Record the VOA reference and council account separately, compare dates and highlight unexplained changes. Avoid advising that a formal challenge is warranted until the valuation evidence and potential financial effect have been assessed.
