Self storage in Portsmouth

The self-storage market in Portsmouth

Storage Compass tracks 5 self-storage facilities in Portsmouth, holding an estimated 146,350 sq ft of lettable space between them. Every figure on this page is rebuilt from live sources rather than a one-off survey, so the counts move as the market does.

The Portsmouth market is served by 4 named operators. Safestore Self Storage (2 sites), Big Yellow Self Storage (1 site), Shurgard (1 site) and Shurgard Self Storage Portsmouth (1 site) are the largest by site count. Brand concentration matters locally: where one operator holds most of the space, advertised rates tend to move together rather than compete.

By build format, Portsmouth runs 4 indoor climate-managed sites and 1 mixed-format site. Format drives cost to serve: container yards are cheap to build and quick to open, while indoor multi-storey stock carries higher fit-out cost but attracts longer average stays.

What storage costs in Portsmouth

No site in Portsmouth currently publishes a live online rate, so there is no advertised price range to report. Operators here quote on request, which typically means pricing is set per enquiry against current occupancy. If you are comparing costs, ask each site for a rate on the same unit size and the same minimum stay, otherwise the quotes are not comparable.

Is Portsmouth over or undersupplied?

Portsmouth has 0.68 sq ft of storage per resident against a UK average of 0.9 sq ft, roughly 24% below the national benchmark. That is measured across a population of 214,321 living in about 86,155 households. On this measure the local market reads as balanced.

Around 46.6% of Portsmouth households rent rather than own. Renter share is one of the strongest predictors of self-storage demand in the UK because renters move more often, have less loft and garage space, and are more likely to need medium-term overflow storage between tenancies.

Planning pipeline and site context

No self-storage planning applications have been filed in Portsmouth in the last 12 months. A quiet pipeline means the current facility count is likely to be the supply position for at least the next two years, since even a consent granted today would not usually open before then.
