What was argued and what the tribunal found

Sky UK Limited appealed the rateable value of its 37-acre headquarters site comprising nine office buildings, car parks, food court and fitness centre, seeking a 7.5% fragmentation allowance to reflect the piecemeal development of the site from the late 1970s through 2022. The Tribunal found that while the comparables submitted by the Valuation Officer (purpose-built office buildings) did not demonstrate that fragmentation issues were reflected in the main space rate of £125/m², the subject property's construction in a piecemeal fashion was material. The Tribunal awarded an allowance of 2.5% for fragmentation effective from 1 April 2017, citing The Hut Group tribunal decision as the most persuasive evidence, reducing the RV from £10,030,000 to £9,750,000 for the initial period.
