The Q1 2026 European Self-Storage Index: A Quantitative Analysis

The Q1 2026 edition of the European Self-Storage Index, compiled from The Storage Scanner data tracks pricing dynamics across 52,264 unique unit-level profiles spanning twelve national markets. The headline finding for the first quarter of 2026 is one of aggregate stability masking pronounced regional divergence. The pan-European blended rate edged up a statistically negligible +0.15% in nominal terms, while the average price per square metre actually contracted by -0.03%. Beneath that placid surface, however, three markets - Switzerland, Austria, and Denmark - posted clear upward moves, whereas France, the Netherlands, Norway, and Germany each registered contractions that, if annualised, would translate into meaningful year-on-year softness.

The quarter's clearest structural theme is the outperformance of large (over 10 m²) units, which rose +0.43% on average while all three smaller segments printed modest declines. This is consistent with a demand mix tilted toward household and light-commercial storage needs rather than the entry-level tenant profile that typically underpins sub-2 m² pricing power.

Methodology

The index is constructed from unit-level asking-rate data scraped across the publicly advertised listings aggregated by The Storage Scanner. Four size buckets are applied: Small (under 2 m²), Medium (2–5 m²), Medium (5–10 m²), and Large (over 10 m²). Two price series are maintained for each observation: the total monthly asking rate and the rate normalised per m². Start-of-quarter and end-of-quarter snapshots are differenced to produce both an absolute delta (in currency units) and a percentage delta. To reduce the impact of extreme listings - whether mispriced, promotional, or otherwise unrepresentative - the series has been winsorized at the 95th percentile, meaning observations above that threshold are capped rather than excluded, preserving sample size while neutralising tail distortion. The European Average row is reported in EUR using the prevailing cross-rates implied in the underlying source. National rows retain their local-currency denomination.

European Aggregates

At the pan-European level the market was essentially unchanged during Q1 2026. The blended monthly rate moved from €168.85 to €169.11, an increase of just €0.25 or +0.15%. On a per-square-metre basis the shift was marginally negative at -0.03% (€24.22 → €24.21). The stability of the per-m² figure is the more informative of the two, as it neutralises mix effects from changes in the composition of units advertised.

Table 1. European blended averages by size category (EUR)

Three features of Table 1 deserve attention. First, the Large segment is the only size bucket to record a positive move on both a total and per-m² basis, which materially drove the aggregate nudge into positive territory. Second, the mid-size segments (2–5 m² and 5–10 m²) moved in lockstep (-0.17% and -0.20% per m² respectively), suggesting a broad-based, rather than segment-specific, softening in household-scale storage. Third, the sub-2 m² segment, typically the most price-inelastic category because it services box-and-parcel tenants, was almost perfectly flat, indicating that operators have preserved pricing power at the very small end even as the mid-size segments soften.

Country-Level Performance

The dispersion across national markets was wide. Measured by the change in the national blended rate, Switzerland led the index at +5.67%, with Austria (+3.24%) and Denmark (+1.45%) rounding out the positive tier. At the other end of the distribution, France posted the quarter's weakest reading at -1.87%, followed by the Netherlands (-0.61%), Norway (-0.55%), and Germany (-0.53%).

The Leaders: Switzerland, Austria, Denmark

Switzerland stands out unambiguously. Every size category posted an increase, with the headline price per m² rising from CHF 36.28 to CHF 37.91 (+4.47%). The Large segment in particular, which represents the bulk of Swiss sample volume (750 of 1,803 unit profiles), saw a CHF 31 monthly uplift (+6.17%). This is consistent with a market operating near capacity: where occupancy is tight, operators pass through both inflation and repricing actions directly. The Swiss result is all the more notable given that its absolute pricing levels (CHF 37.91/m² blended) are already the highest in the Continental European cluster.

Austria's +3.24% blended gain was driven disproportionately by the Large segment (+6.93% total, +6.12% per m²). The small-unit segment also rose +4.27%, a combination that suggests the Austrian market experienced broad-based rent increases rather than a single-segment anomaly.

Denmark's +1.45% headline move was the most uniform of the three leaders, with all four size categories contributing positively. Denmark also remains Europe's highest-priced market on a per-m² basis outside the Nordic currency bloc when adjusted for cross-rates, with the Large segment alone clearing DKK 2,263/month.

The Laggards: France, Netherlands, Norway, Germany

France's -1.87% contraction is the clearest soft-market signal in the dataset. Every size category moved negatively, and the per-m² blended rate fell -1.51% (€17.95 → €17.68). With a sample of 5,694 unit profiles - comparable in scale to Spain's - this is unlikely to be a small-sample effect. The French data is consistent with an operator cohort competing for marginal demand in an oversupplied market; the symmetric decline across segments argues against a mix-shift explanation.

The Netherlands' -0.61% headline masks a more aggressive per-m² contraction of -1.03%. The Dutch market carries Europe's second-largest profile count (9,970), so this move is well-supported statistically. Given Dutch starting rates are already among the lowest in Europe (€19.03/m² blended start, behind only Belgium and France), the contraction implies operators are actively defending occupancy rather than margin.

Germany, Europe's largest sample at 11,364 unit profiles, posted -0.53% on the blended rate and -1.17% per m². The softness is concentrated in the small-to-medium segments (Small -1.81%, Medium 2–5 m² -1.98%, Medium 5–10 m² -1.35%), while the Large segment was flat at +0.06%. This bifurcation - softness in household-scale units, stability at the large end - is economically intuitive if the marginal German tenant is deferring consumption while commercial and long-haul household tenants remain anchored.

Norway's -0.55% decline was shallow but broad: three of four segments fell, with only the smallest bucket posting a marginal (+0.40%) gain. Given Norwegian rates are the highest in the dataset in local-currency terms (NOK 235/m²), even modest erosion at this level is material.

The Middle: UK, Spain, Ireland, Belgium, Sweden

The United Kingdom's blended rate fell -0.24%, but the per-m² figure actually rose +0.36% - an unusual dichotomy indicating a shift in mix toward smaller, higher-priced-per-m² units rather than genuine weakness. Spain (+0.33%), Ireland (+0.34%), and Belgium (+0.05%) were all essentially flat on both metrics. Sweden's -0.17% / -0.21% reading is similarly close to stasis.

Size-Category Heatmap

Cross-tabulating country against size category reveals the fault lines more cleanly than the aggregate statistics.

Table 3. Q1 2026 per-m² change (%), by country and size

Several patterns emerge. The small (<2 m²) column is the most dispersed, ranging from -3.92% (Belgium) to +4.67% (Austria) - a span of more than eight percentage points in a single quarter. This reflects the structural thinness of the small-unit subsample in many markets (Ireland has only 51 unit profiles, Denmark 93) and the relative ease with which operators can reprice low-absolute-value units. The Large column, by contrast, is more concentrated, consistent with that segment's reliance on longer contractual tenures and more price-sensitive commercial demand.

Pricing Levels: Where Does Europe Stand at the End of Q1 2026?

Focusing on the end-of-period per-m² figures in local currency clarifies the pricing hierarchy.

Table 4. End-of-Q1 2026 price per m² (all-sizes blended, local currency)

Adjusting mentally for cross-rates (CHF and GBP trading broadly at parity with EUR; Nordic currencies at a material discount), the genuinely high-rent European markets are Switzerland, Denmark, and Austria. The lowest-rent markets - France, Belgium, and the Netherlands - form a contiguous geographic cluster, which is consistent with a single competitive pricing corridor across the Low Countries and northern France.

Key Findings

The quarter's evidence supports four substantive conclusions. First, the pan-European market is in equilibrium at the aggregate level, but that equilibrium conceals a clear bifurcation between a strengthening Alpine–Nordic axis (CH, AT, DK) and a softening continental core (FR, NL, DE). Second, the Large-unit segment is the only size category exhibiting consistent pricing power at the European level, which is worth monitoring as a potential leading indicator of commercial storage demand. Third, the French market warrants closer attention: a -1.87% quarterly move on a sample of 5,694 unit profiles is the most statistically robust bearish signal in the dataset. Fourth, the British market illustrates the importance of separating total-price and per-m²-price signals - a -0.24% headline gives way to a +0.36% per-m² figure, highlighting how mix effects can mask underlying dynamics.

Limitations and Caveats

Three caveats apply. The index reflects advertised asking rates rather than executed contract rents, and so tends to lead actual realised revenue changes. Second, cross-country comparisons in levels are sensitive to the FX regime used and to local VAT conventions, neither of which has been harmonised in the raw source. Third, the 95th-percentile winsorisation, while appropriate for suppressing outlier distortion, will attenuate the magnitude of genuine high-end repricing - meaning the Swiss and Danish gains may, if anything, be understated.

Outlook

Absent a material macroeconomic inflection, the Q2 2026 reading is most likely to show a continuation of the current dispersion pattern: sustained firmness in Switzerland and Austria, stabilisation in Denmark, further softness in France, and a test of support in Germany and the Netherlands. The size-category signal - Large firm, mid-range soft - bears particular watching; if it persists into Q2, it would argue for a structural, rather than cyclical, bifurcation in the European self-storage demand profile.
