Comparison table of online storage sites

The table below compares the four main French players in online storage on the criteria that weigh in the decision: price per cubic metre, storage type, accessibility, security, insurance and contract flexibility.

The methodology relies on public prices displayed by each platform in May 2026, a sample of 200 listings in the Paris region, Lyon, Marseille, Bordeaux and Toulouse, and aggregated 12-month rolling Trustpilot reviews.

Why choose online storage in 2026

The French storage market has undergone a profound transformation since 2020. The peer-to-peer storage segment (P2P), driven by digitalisation and pressure on purchasing power, multiplied its booking volume by 3.5 between 2020 and 2025 according to the 2025 Xerfi report on storage services. Classic self-storage retains the dominant value market share (78 percent of sectoral revenue) but loses ground in volume on low-security private uses.

Three use cases dominate online storage demand: temporary moves (32 percent of rentals according to the Xerfi panel), expatriation or professional mobility (18 percent), permanent lack of space in an urban home (24 percent). The rest splits between personal or professional archiving, seasonal storage (summer bikes, ski equipment, garden furniture) and inheritance storage pending division. The economic logic is similar to the one described in the guide how much does a move cost, with storage as the adjustment variable between homes.

The trade-off between peer-to-peer storage and classic self-storage plays on three variables: price per cubic metre (ratio 1 to 4), desired access frequency (P2P by appointment, self-storage on free access) and value of stored goods (P2P for everyday goods, classic or premium self-storage for valuable goods).

Criteria when choosing an online storage service

Six criteria structure the decision:

• Price per cubic metre per month, compared by including possible file fees, cancellation fees and seasonal surcharges.
• Access type: free 7 days a week (self-storage) or by appointment (P2P).
• Physical security: video surveillance, alarm, access control, on-site presence, type of closure (padlock, badge, biometrics).
• Included insurance and maximum extension amount possible, with particular attention to exclusions (fragile goods, musical instruments, artworks).
• Contractual flexibility: minimum duration, cancellation notice, possibility to change volume during the contract.
• Site accessibility: floor, lift, parking, useful ceiling height (for tall furniture), distance from home.

Costockage, the French leader of peer-to-peer storage

Costockage is a French company founded in 2014, European leader of collaborative peer-to-peer storage. The platform lists more than 15 000 storage spaces in mainland France (cellars, garages, attics, outbuildings, unused commercial premises) rented by individuals or small professionals to other individuals. The positioning is built on three pillars: a price 3 to 5 times lower than classic self-storage, an all-risk insurance included, and systematic verification of both parties on the platform costockage.fr.

Costockage’s business model is based on a platform commission on the monthly price (15 to 20 percent depending on segment). The platform manages the entire journey: search by area and volume, contact between parties, contract signature, secure monthly payment, insurance, handling of possible incidents. Access to spaces is by appointment with the host, on average within 24 to 48 hours, which is the main difference with classic self-storage.

Key features of the Costockage offer

• Prices: between 4 and 12 euros per cubic metre per month depending on the area and the type of space, national average of 6 euros per cubic metre. Studio volume (7 m³) at 35 to 50 euros per month, 3-room flat volume (15 m³) at 90 to 120 euros per month.
• Coverage: 15 000 spaces listed across all French regions, with stronger density in the Paris region and the 10 largest metropolises.
• Insurance: all-risk included up to 5000 euros by default (theft, fire, water damage), extension possible up to 50 000 euros for 5 to 15 additional euros per month.
• Host verification: ID document, ownership or lease proof, photographic inventory of the premises, random check on 10 percent of listings by Costockage teams.
• Deposit: 200 to 500 euros depending on volume, released at the end of the contract.
• Duration: 1 month minimum, no commitment, 30-day cancellation notice.
• Access: by appointment with the host, on average within 24 to 48 hours, flexible slots.
• Average rating: 4.5 out of 5 on Trustpilot (8500 cumulative reviews in 2025).

The platform covers all volumes, from 1 cubic metre (additional cellar) to 100 cubic metres (entire family storage). For buyers who rent their home short-term during an extended absence, Costockage logically combines with an Airbnb concierge service, with personal furniture moved to storage during the tourist rental period of the main home.

Detailed comparative analysis between Costockage, Homebox, Jestocke and Shurgard

The four players occupy structurally complementary positions in the online storage market. An honest analysis of their strengths and limits is based on the nature of the storage offered (P2P vs professional self-storage) and on the price-security-accessibility trade-off.

Homebox is the historical French leader of digitalised classic self-storage. Founded in 1996 and accelerated in its digitalisation since 2018, the group operates 100 centres in France spread across 60 cities. The model is based on individual secured units in dedicated logistics centres, with free access 7 days a week via badge or code, 24-hour video surveillance and individual alarm. The average price of 25 euros per cubic metre per month is 4 times higher than Costockage, but the service brings higher physical security, unlimited access and the reliability of a professional operator. The positioning particularly suits businesses (archiving), individuals moving valuable goods and uses where access frequency is high.

Jestocke is the second French peer-to-peer storage platform, founded in 2013. With 8000 listed spaces, it offers a less extensive catalogue than Costockage but very similar prices (7 euros per cubic metre per month on average). The main difference lies in product experience (interface, booking journey, incident management) and in regional density, Costockage being more present in the Paris region and Jestocke more present in the South-West and Auvergne-Rhône-Alpes regions. Both platforms apply comparable insurance and verification rules.

Shurgard, European leader of premium self-storage, operates 70 centres in France mainly in metropolises (Paris, Lyon, Marseille, Bordeaux, Toulouse, Lille, Nantes, Strasbourg, Nice, Montpellier). The positioning is more upscale than Homebox on security (next-generation cameras, biometric access control in 40 percent of centres in 2026, permanent staff presence on weekdays) and on centre comfort (air conditioning, standardised 2.40 metre ceiling height, freely available trolleys). The average price of 28 euros per cubic metre per month makes it the most expensive option in the comparison, justified for very high-value goods or demanding professional uses.

“The self-storage market in France reached 1.1 billion euros in 2025, growing 8 percent per year since 2020. The peer-to-peer storage segment represents 12 percent of this market by value but 28 percent by booking volume, a sign of usage democratisation on lower-value goods.” — Xerfi, Report on the self-storage market, 2025

Which online storage service to choose depending on your profile

The optimal choice depends less on displayed price than on the fit between offer and specific expectations. Four profiles emerge when choosing online storage.

Profile 1: temporary move and constrained budget

For an individual who must temporarily store the contents of a studio or one-bedroom flat during a transition (sale before purchase, 6 to 24 month expatriation, long renovation), Costockage is the most rational economical option. The average price of 35 to 90 euros per month for 7 to 12 cubic metres represents a 75 percent saving compared with classic self-storage over 12 months, that is 1500 to 2500 euros preserved. The insurance included up to 5000 euros covers most everyday furniture.

Profile 2: frequent access and professional needs

For a company archiving documents, a retailer storing seasonal stock or an individual accessing their storage regularly (more than 2 times per month), Homebox is the most operational option. Free access 7 days a week without appointment, the security of a professional operator and the dense national coverage make it the B2B and high-access-frequency market standard. The higher price is offset by the productivity of free access.

Profile 3: P2P storage in province or tight market

Jestocke suits individuals located outside the Paris region, particularly in the South-West and Auvergne-Rhône-Alpes regions where Jestocke offer density is higher than Costockage. Pricing and contractual conditions are very close to Costockage, the trade-off being mainly on local availability and host profile.

Profile 4: valuable goods and maximum security requirement

For storing artworks, musical instruments, sensitive archives or high-value heritage furniture, Shurgard brings a higher security level (biometrics, permanent surveillance, controlled climate) that justifies the premium price. The platform also suits demanding professional uses (law firm, certified accountant, antique dealer). The trade-off is a price 4 to 5 times higher than Costockage, to integrate in a bundled purchase logic with other equipment services such as equipping a kitchen with refurbished appliances during a complete relocation.

Practical tips for renting online storage

Six checkpoints secure the rental regardless of the chosen platform.

Mistakes to avoid

1. Confusing m² and m³: a 5 m² unit with 2.40 m ceiling height equals 12 m³, that is 80 euros per month at Costockage but 300 euros at Homebox. The confusion completely distorts the price comparison.
2. Underestimating access frequency: a P2P by appointment becomes impractical beyond 2 visits per month, to integrate in the total cost calculation.
3. Ignoring insurance exclusions: most contracts exclude jewellery, cash, irreplaceable documents, artworks above a certain value, to store elsewhere.
4. Choosing without testing actual access: a unit only accessible by stairs, without a furniture lift, can turn a 2-hour move into a full-day project.
5. Neglecting temperature conditions: a non-insulated attic can reach 50 degrees in summer, which damages leather, electronics, photos and precious wood.
6. Booking at the last minute: availability drops sharply in June-July (school and professional moves), to anticipate 3 to 6 weeks in advance.
