Is a self-storage unit worth it?

Self-storage sells on the monthly figure, which is small, and the cost is annual and open-ended, which is not. The industry knows perfectly well that the average tenancy runs far longer than the customer intended, because the cost of deciding what to do with the contents is paid in one difficult afternoon and the cost of not deciding is paid in small monthly instalments. That asymmetry is the entire business model, and it is also the thing to guard against.

Step by step

1. Do the annual sum before anything else.Monthly rate times twelve, plus insurance, plus the padlock, plus the van hire at both ends. Compare that with the honest second-hand replacement cost of what is going in. For ordinary household goods the comparison is usually stark.
2. Ask whether there is an end date.A move with a gap between completion dates, a renovation, six months abroad, a house being sold through probate, a relationship ending. All of those have a date, and a unit is genuinely the right tool. "Until I decide" has no date and is the expensive case.
3. Check what the price actually includes.Whether insurance is compulsory and whether you may use your own, the notice period, whether the rate is introductory and what it rises to, access hours, and whether there is a fee for the first month or the padlock. The advertised rate is rarely the paid rate.
4. Size it honestly and then go one size down.Units are quoted in floor area but you are buying volume, and stacking properly usually gets you into a smaller unit than the sales estimate. Take a tape and a list of your largest items.
5. Check the environment for what you are storing.Most units are unheated. That is fine for furniture and tools and poor for photographs, documents, electronics, musical instruments, vinyl and anything with a battery. Ask about humidity control specifically rather than assuming.
6. Check the insurance position properly.Home contents insurance sometimes extends to goods in storage, often at a low limit, and the operator's own cover has its own exclusions. Do not assume either. Read what is excluded, which usually includes damp, moth and anything unlisted of high value.
7. Inventory and photograph everything going in.Numbered boxes, a list on your phone, photographs of anything valuable. It is what makes a claim possible and it is what stops you renting a unit for two years because you do not know what is in it.
8. Set the end date in your calendar when you sign.With a reminder a month before. This one step is what separates the people who use storage as a tool from the people who are still paying in 2031.
9. Consider the alternatives first.A friend's garage, a neighbour's shed, a smaller container for the genuinely irreplaceable and disposal for the rest, or simply selling the furniture and rebuying at the other end, which for ordinary items is frequently cheaper than a year of storage.

Alternatives

• Container storage: Usually cheaper per cubic metre than a self-storage room, often on a farm or industrial yard. Access is less convenient and it is normally unheated with more humidity variation.
• Removal company storage: Useful when there is a gap between moves, because the goods stay containerised and are handled once. Charged by container and by handling, and access during the period is limited or impossible.
• Store with family: Free, and it costs a relationship if the end date is vague. Write down what is stored and when it is going, exactly as you would with a commercial operator.
• Sell and rebuy: For ordinary furniture and white goods, a year of storage frequently exceeds the cost of replacing them second-hand. Genuinely worth calculating rather than dismissing.
