Development update

Big Yellow is pleased to announce that it has opened its new 70,000 sq ft store at Staines, West London. The store is located prominently on the Causeway and will serve a new catchment area for Big Yellow, with our nearest store seven miles away. 

We have a further three stores due to open this financial year; Queensbury, London (72,000 sq ft opening in October 2025), Slough Bath Road (95,000 sq ft opening in February 2026), and Wembley, London (73,000 sq ft opening in March 2026). We anticipate opening a further four stores in the year ending 31 March 2027, with West Kensington, London following in 2028.

Jim Gibson, CEO, commented:

"This is the first opening of the nine sites that we are currently constructing, which will add 730,000 sq ft of capacity (11% of our current MLA). These sites, along with the other five in our pipeline, will add a proforma net operating income of approximately £37 million, a return of 8.8% on the total development cost of £422 million, including land already acquired, of which £214 million has been spent to date."
