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 around 1077 self storage sites in the UK, of which 195 facilities only offer container storage.
In total, there is approximately 37.6 million sq ft of self storage space in the UK, and we estimate that the total turnover of the industry in 2015 was £440 million among approximately 490 operators.
Of all the self storage facilities in the UK, a third are held by the larger operators (managing 10 sites or more). However as these operators tend to have larger sites, and many are located in higher rent locations, in terms of total space available and revenue, their share of the market is likely to be close to half.
