Big Yellow Group PLC

("Big Yellow", "the Group" or "the Company")

Disposal of Staines Industrial Estate

Big Yellow announces that it has contracted to sell its industrial estate in Staines, Surrey for £36.5 million and has received the £2 million retention held back from the previously announced sale of its Harrow industrial estate.  The Group will have received gross proceeds of £75 million from these two disposals.

The Company's preferred gearing metric, net debt to EBITDA, currently stands at approximately 3.7x and is expected to fall in due course to our target of 3.5x.

We can also report that since the end of Q1 we have opened new stores in Epsom, Kentish Town and a relocation store at Staples Corner (all in London).  These recent store openings contribute to a total of seven new stores brought online since July 2025, which are making an increasing contribution to revenue and will shortly help drive the profitability of the business.

John Hunter, CEO, commented:

"We are largely able to fund our capital expenditure this year and next from capital receipts and retained cash flow, without materially increasing absolute levels of debt.  We believe a robust balance sheet and prudent capital structure is of heightened importance in the current external environment."

Notes to Editors 

Big Yellow is the UK's brand leader in self storage and operates from a platform of 115 stores.  We have a pipeline of 0.8 million sq ft comprising 10 proposed self storage facilities.  The current maximum lettable area of the existing platform is 6.9 million sq ft.  When fully built out the portfolio will provide approximately 7.7 million sq ft of flexible storage space.  99% of our stores and sites by value are held freehold and long leasehold, with the remaining 1% short leasehold.  Currently by revenue 75% of our stores are in London and its commuter towns, with the balance in larger regional conurbations.

Our stores utilise state of the art technology for our digital and operating platforms including security, and we focus on locating our stores in high profile, accessible, main road locations.  We also focus on providing excellent customer service, a highly engaged employee culture, and with a significant investment in sustainability.
