Sky, Grant Way, TW7 5QD

What was argued and what the tribunal found

The appellant sought an allowance for fragmentation of the 37-acre site comprising nine office buildings and other features, initially requesting 20% at the challenge stage and reducing to 7.5% before the hearing. The Valuation Officer argued that any disadvantage was already reflected in the £125/m² main space rate and cited comparable properties with higher rates. The tribunal found that the piecemeal construction of the subject property created material fragmentation warranting an allowance, as a hypothetical tenant would factor in costs and inefficiencies arising from multiple dispersed buildings. The tribunal awarded a 2.5% fragmentation allowance, finding persuasive support from the January 2026 Hut Group decision, resulting in revised rateable values ranging from £9,750,000 to £10,580,000 across the material dates.
