AI confidence in this short overview: medium

This case concerns two unopposed Valuation Officer appeals challenging Valuation Tribunal reductions to rating assessments for office hereditaments fitted out to Category B. The central issue is how to reflect the value of tenant-installed Cat B fit outs where direct Cat B rental evidence is scarce, and whether the statutory percentage in the 1989 Regulations must be applied to convert capital fit-out cost into an annual value. The tribunal preference is to use direct Cat B rental evidence where reliable, and otherwise to allow an uplift to Cat A rents by amortising fit-out cost; application of the 1989 Regulations' percentage is permissive, not mandatory.

Ratio decidendi

This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.

AI confidence in this ratio decidendi summary: medium

Where reliable market evidence of Cat B lettings exists, that evidence should be preferred to measure the value attributable to Cat B fit out; only if such comparables are unreliable or unavailable is it appropriate to resort to cost-based/amortisation methods. Where the fit-out capital cost relates to the whole hereditament, a valuer may apply the percentage specified in the 1989 Regulations to derive an annual equivalent but is not obliged to do so — other amortisation or years'-purchase approaches can be permissible.

Obiter dicta

This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.

AI confidence in this obiter dicta summary: medium

The tribunal expressed regret at the generally poor quality and paucity of Cat B rental evidence and urged the production of better market comparables to avoid reliance on a two-stage approach. It also observed that a tenant's tax treatment of its own fit-out expenditure is a consequence of reality and does not by itself preclude including the tenant-installed fit out in valuation.
