Notes to Editors 

Big Yellow is the UK's brand leader in self storage and operates from a platform of 113 stores.  We have a pipeline of 0.9 million sq ft comprising 12 proposed self storage facilities.  The current maximum lettable area of the existing platform is 6.7 million sq ft.  When fully built out the portfolio will provide approximately 7.6 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.
