Size of the Industry
It is always hard to accurately measure the exact number of self storage sites, as they are not officially registered anywhere and small facilities can be opened in rural areas with limited marketing or online presence. The SSA UK estimates that there are now over 1500 self storage sites in the UK, of which 345 facilities offer predominately container storage.
In total, there is approximately 44.6 million sq ft of self storage space in the UK, and we estimate that the total turnover of the industry in 2017 was £750 million.
Around 30% of UK self storage facilities are owned or managed by large operators (operators managing 10 or more sites) however, since these operators tend to have larger sites, and many are located in higher rent locations, in terms of total space available and total revenue, their share of the market is likely to be well over 40%.
