The UK self storage industry is the largest and most mature in Europe. As of 2026 there are more than 5,100 self storage facilities across the UK, holding around 64.3 million square feet of rentable space and generating over £1.2 billion in annual turnover. The UK accounts for roughly 32.9% of the entire European self storage market.
This report sets out the numbers that matter: how many facilities there are, what they cost, where they are concentrated, who runs them, and how demand is changing. The figures are drawn from the Self Storage Association UK (SSA UK), Janus International Europe, and Stora, and are current for 2026.
The UK self storage market at a glance
| Metric | Value |
|---|---|
| Total UK facilities | 5,100+ |
| Total rentable space | 64.3 million sq ft |
| Annual industry turnover | £1.2 billion+ |
| Average national rate | £29.13 per sq ft per year |
| Average occupancy | 75.1% |
| UK share of European market | 32.9% |
| Market held by independent operators | around 70% |
Two facts stand out for anyone trying to understand the industry. First, the market is highly fragmented: roughly seven in ten facilities are run by independent operators rather than the big national chains. Second, average occupancy sits at 75.1%, which means the typical facility still has space to fill, and competition for customers is real.
What self storage costs in the UK
The national average rate is £29.13 per square foot per year, which works out at about £2.43 per sq ft per month. In practice, customers pay by the unit rather than by the foot, so the figures below reflect what a typical unit actually costs each month.
| Unit size | Real-world equivalent | Typical monthly cost |
|---|---|---|
| 25 sq ft | Garden shed | £40–£100 |
| 50 sq ft | One-bedroom flat | £95–£160 |
| 75–100 sq ft | Single garage | £190–£320 |
| 150–200 sq ft | Double garage or Luton van | £285–£450 |
Prices track local property values, because rent is a facility's single biggest cost. London and the South East therefore sit well above the national average, while the North of England, Scotland, and Wales are noticeably cheaper. For a fuller breakdown, see our UK price guide.
Regional breakdown
Self storage is not evenly spread across the UK. Supply is heavily weighted towards London and the South East, while the fastest growth is happening in the North.
| Region | Approx. store count | Rentable space | Year-on-year growth | Average rate (per sq ft/year) |
|---|---|---|---|---|
| London & South East | 1,800+ | 22.0 million sq ft | +5.1% | £38–£52 |
| North of England | 378 | 13.0 million sq ft | +9.2% | £18–£24 |
| Scotland & Wales | 248 | 8.3 million sq ft | +8.0% | £17–£22 |
| Midlands | 195 | 6.8 million sq ft | +7.4% | £20–£26 |
The headline here is the North of England, growing at 9.2% year on year, the fastest rate in the country. Cities such as Manchester, Leeds, and Liverpool remain undersupplied relative to demand, which makes them the regions to watch over the next few years.
Who operates UK self storage
The market splits into a small number of large national chains and a long tail of independents. The major operators include:
- Safestore, the largest UK operator, with around 138 stores and reported revenue of £234.3 million in FY2025.
- Big Yellow Group, with 111 stores and £156.3 million in revenue reported for Q3 FY2026.
- Shurgard, which expanded its UK footprint significantly after acquiring Lok'nStore for £378 million.
Between them the national chains hold roughly 30% of the market. The remaining 70% is made up of independent operators, many of which are single-site businesses with little or no marketing budget. This is the structural feature that defines UK self storage: a handful of recognisable brands sitting on top of thousands of local, independently run facilities.
How customers use self storage
Demand splits across two broad groups:
- Residential, around 73% of customers. The biggest drivers are moving house, downsizing, renovation, and life events such as divorce, bereavement, and inheritance. These customers tend to stay for shorter periods.
- Business, around 24% to 25% of customers. This is the fastest-growing segment. Business users include e-commerce sellers storing stock, tradespeople storing tools and equipment, and companies archiving documents. They typically stay far longer, often 24 months or more.
A growing share of capacity is container-based rather than purpose-built indoor space. Recent surveys put container storage at roughly 39% of all UK locations, which reflects how quickly lower-cost, outdoor-led sites have expanded outside the major cities.
Demand patterns and seasonality
Self storage demand is seasonal, and the pattern is predictable enough to plan around:
- Indoor occupancy peaks in October, at around 77%, driven by late-summer house moves and the start of the university year.
- Container occupancy peaks in November, at around 72%, as businesses build up winter inventory.
- Demand is softest in late winter and early spring, which is usually the best time to negotiate a rate or pick up a move-in offer.
The way people find and book storage has also shifted decisively online. About 59% of industry web traffic comes from Google Search, roughly 90% of facilities now support online booking, and 44% of customers read reviews before booking. Transparent, upfront pricing matters more than ever: visible prices drive an estimated 72% of online bookings, yet many operators still hide them behind an enquiry form.
What this means for 2026
Three trends are shaping the year ahead. The North is the growth story, outpacing the South on new supply and demand. Business storage is the fastest-growing segment, with longer stays and higher lifetime value than residential customers. And the independent majority is increasingly visible online, as the 70% of operators outside the national chains compete for the same Google searches and review-led bookings as the brands.
For anyone comparing facilities, the practical takeaway is simple: the UK has a large, competitive, well-supplied market, which means there is almost always a better-priced or better-located option nearby. Search self storage near you to compare facilities, prices, and reviews in your area.
