The Northumberland self storage market

Northumberland sits within the North East self storage market. Northumberland is the northernmost and least densely populated county in England, with Morpeth as its administrative centre and Blyth its largest town. We arrange acquisition finance, commercial mortgages, bridging, development finance, mezzanine and term debt on storage facilities across the county, tracking 3 storage catchments, led by Cramlington.

The market figures below are reported nationally or at regional level by the industry's research sources, attributed to each source, and used as context rather than a Northumberland-specific measurement. The housing-transaction and planning data is genuinely local and sourced from HM Land Registry and council planning registers.

Storage catchments and operators across Northumberland

Storage demand concentrates along the A189, A1, A193, A19 and A192 corridors, where road access and passing visibility drive enquiries.

Rates, occupancy and yields

Nationally there are 3,143 self storage stores offering 67.5m sq ft of lettable space (SSA UK / Cushman & Wakefield Annual Industry Report, 2026 report), with average occupancy of 74.5% across all stores and 79.6% for mature stores. Average revenue runs at about £27.40/sq ft (UK average, SSA UK / Cushman & Wakefield, 2026 report), and prime self storage yields sit around 5% (Savills, European Self Storage Spotlight, Q4 2025).

Capital values: what storage facilities sell for

What do trading stores actually sell for? The best public evidence comes from the listed operators' external valuations. Big Yellow's London and commuter-town weighted portfolio was valued at £458/sq ft of lettable area and its smaller-format regional Armadillo stores at £185/sq ft (Big Yellow FY2026 results (JLL-valued), Mar 2026), with Safestore's UK estate at about ~£364/sq ft on a derived basis (Safestore FY2025 results (Cushman & Wakefield-valued), Oct 2025). The evidenced span from regional secondary to prime London and the South East runs at roughly £185 to £460/sq ft. These are going-concern values for trading businesses, not vacant-possession property values, and no source publishes a finer regional split, so we treat them as tier benchmarks when appraising a Northumberland store.
