Flexible storage rental means the solution moves with what happens in your life — not the other way around. With mobile storage, that flexibility runs on four axes: how long you rent, how much space, where we come, and how much help you choose. Below: everything possible, plus the honest limits.
You choose a minimum rental period when booking: 1, 3, 6 or 12 months. The longer you commit, the lower the monthly rate — with increasing discount up to 25%.
Tip: unsure? Our data from over 4,700 customers shows 45% choose 3 months and 25% choose 1 month. For full pricing per period and volume, see what storage costs per month.
With mobile storage you rent storage space, not a fixed box. On request we can scale your package up or down — units combine in steps of 4, 6 and 8m³.
Tip: unsure about volume at the start? In how much storage space you need you'll find references per home type for a solid first estimate.
Unlike traditional self storage, with us you're not stuck to one physical location. You can change pickup and return addresses later — also if you move in the meantime.
Tip: the location-freedom argument is one of the main differences with self storage. In self storage vs. mobile storage we lay out all the differences.
For each pickup or return, you choose the service level that suits that moment. You're not locked into one choice for the whole contract.
Our data from over 4,700 customers shows: 45% choose a minimum period of 3 months, 25% go for 1 month with maximum freedom, and the remaining 30% split almost evenly between 6 and 12 months (about 15% each). Formally, customers commit to 4.53 months on average — but the actual storage story lasts 8 months on average. Flexible extending is the norm, not the exception.
According to the European Self Storage Industry Report 2025 by FEDESSA, storage customers fall into two groups: short stays (3 to 9 months) and long stays (2 years or more). Our structure of minimum periods plus monthly extension serves both groups without separate contracts — you don't have to decide upfront whether you're in the short or long group.
With traditional self storage, you're often stuck to a specific box size at a specific location for a specific minimum term. With mobile storage, you rent space that adapts: more units added, units removed, move along to a new address, service level chosen again per pickup. That freedom is built into the model — not something you pay extra for.

The questions that come up most about flexibility — including honest answers about what isn't possible.
No, the minimum period is fixed — that's how you get the associated discount. There is flexibility before pickup though.
Automatic: after the minimum period, the agreement extends per full month with a 14-day notice period.
Yes, downgrade is possible on request at any time. One point to be clear about: we rent space, not contents.
Technically yes, in practice almost never used — and usually not the most logical choice.
Tip: with renovations, duration often turns out different than expected. In storage during your renovation you'll read how customers usually set that up.
Choose based on how certain you are of the duration — not on how long you think you need.
Tip: for seasonal storage (garden furniture, ski gear, Christmas decorations) 3- or 6-month agreements are usually ideal. See seasonal storage for concrete use-cases.


Choose a minimum period from 1 to 12 months with discounts up to 25%. Extend monthly afterwards. Adjust volume, location and service level as your situation changes.
