What was argued and what the tribunal found
The appellants, represented by Ryan Property Tax Services UK Limited, challenged the rateable values of office units at Chiswick Park on the grounds that the entries were inaccurate and sought an unadjusted price of £440 per m2 (compared to the list entries of £465-£475 per m2), arguing the office market had declined between 2017 and April 2021 (the antecedent valuation date). The tribunal found that the appellants' rental analysis, which ranged from £301.88 to £438.67 per m2, failed to properly account for properties being let on full repairing and insuring terms and did not demonstrate that the present tone was excessive. The tribunal preferred the Valuation Officer's evidence, which showed rental analyses substantially exceeding the list entries, and found no persuasive reason to depart from the quantum differentiation already reflected in the list (£475 per m2 for properties under 1,000m2 and £465 per m2 for larger properties). The appeals were dismissed.
