Property Splits and Paramount Control: Why the VOA May Refuse a Split

Direct answer: the VOA may refuse a property split where the evidence does not establish separate rateable occupation or where one party retains paramount control over the whole. Dividing a building physically, issuing licences or allocating rooms on a plan does not automatically create separate assessments.

What paramount control means in practice

The VOA examines who actually occupies and controls each area, the degree of exclusivity, access arrangements, shared facilities and the commercial reality. Documents must match the physical use. Artificial or temporary arrangements are unlikely to be persuasive when one business continues to control the entire property.

Practical example

A warehouse operator licences two enclosed workshops to separate businesses. Each workshop has its own lock, equipment, staff and trading activity, but access and services are shared. The evidence must show the boundaries, rights of access, actual occupation and whether the warehouse operator can freely use or relocate the licensees. The answer turns on control in practice, not the document title alone.

Documents and evidence checklist

• Scaled plans marking each proposed assessment.

• Complete leases, licences and variations.

• Dated photographs of boundaries, locks and access routes.

• Evidence of each occupier's staff, equipment and trading activity.

• Utility, insurance and business records tied to each area.

• Details of shared facilities and who controls them.

• A dated occupation timeline for every unit.

What to do next

Prepare the factual evidence before requesting a split. Keep plans, agreements and photographs consistent. Explain exclusivity and access clearly, including any retained rights. If the VOA refuses, review the stated reason rather than simply resubmitting the same material.

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.

2026 Rating List: What Businesses Need to Check Now

Direct answer: businesses should check the 2026 rating-list entry against the property actually occupied, not only compare the new rateable value with the previous figure. Property description, floor area, use, alterations, splits, mergers and occupation facts can all affect whether further investigation is justified.

Separate the valuation from the bill

The VOA maintains the rating list and rateable value. The council calculates and collects the bill, applies relevant reliefs and records liability. A correct rateable value can still produce an incorrect bill, while a correctly calculated bill may be based on a property entry that needs review.

Practical example

A retailer sees a higher 2026 rateable value but also notices that a demolished rear store remains included in the property description. The retailer gathers dated plans, photographs, contractor records and the prior valuation before assessing whether a factual correction or valuation challenge is appropriate.

Documents and evidence checklist

• 2026 and previous rating-list entries.

• Latest bill and projected liability calculation.

• VOA valuation details, floor areas and property description.

• Lease, rent review and relevant rental evidence.

• Plans, photographs and alteration records.

• Details of changes in occupier, use, split or merger.

• Current relief decisions and council correspondence.

What to do next

Create a property-by-property comparison and record every discrepancy. Check the financial effect before starting formal action. Use relevant evidence rather than assuming that any increase is wrong. Businesses with multiple sites should apply the same review method consistently across the portfolio.
