Self storage in Cardiff

The self-storage market in Cardiff

Storage Compass tracks 6 self-storage facilities in Cardiff, holding an estimated 153,816 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 Cardiff market is served by 6 named operators. 1st Self Access Storage (1 site), M3 Self Storage (1 site), Pink Self Storage (1 site) and Safestore (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, Cardiff runs 4 mixed-format sites and 2 indoor climate-managed sites. 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 Cardiff

No site in Cardiff 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 Cardiff over or undersupplied?

Cardiff has 0.4 sq ft of storage per resident against a UK average of 0.9 sq ft, roughly 56% below the national benchmark. That is measured across a population of 383,919 living in about 147,333 households. On this measure the local market reads as undersupplied.

Around 41.4% of Cardiff 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 Cardiff 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.

On site security context, 21 recorded incidents sit within three quarters of a mile of storage sites in Cardiff, most commonly criminal damage arson, other theft and burglary. This is street-level UK Police open data for the surrounding area, not incidents at the facilities themselves, but it is worth weighing if you are storing high-value items or underwriting a new site.
