How much does self-storage cost, and is it really a more cost efficient option when moving house or going through another major life event? Here, we’ve unpacked the average cost of self-storage plus self-storage insurance so you can assess.

In this guide, we’ve broken down some of the key things you need to know when finding out how much self-storage costs, plus any hidden or additional charges to be aware of.


Self-storage costs vs quality

It’s important to remember that the cheapest storage facility isn’t necessarily the best facility, so although the cost of self-storage should of course factor into your decision-making, don’t let yourself be swayed solely by price.

That being said, it’s always a good idea to get a few different quotes and an idea of how much storage costs monthly or annually to be sure you’re still getting a fair deal for storing your possessions.

Storage facilities will offer different contracts based on a few different factors, which we’ve broken down here:

Self-Storage Units Price per sq. ft.

The average price of a self-storage unit is £27.19 per square foot per year, according the the last Self-Storage Associations industry report.

Most storage facilities will have a number of differently sized storage units and will charge per square foot. Typically, the bigger the unit, the cheaper the price per sq. ft.

With this in mind, it’s important to work out how big a unit you need. It’s also worth taking into consideration whether you are likely to need to add more items to your storage unit in the future or, on the other end of the scale, will be taking items out of storage soon.

If you think you may just be in the cusp of a more expensive bracket, it may be worth assessing your possessions and donating or throwing away the things you are unlikely to actually need after putting them in storage to help you save money.

Self-Storage Costs by Unit Size:

With the above figure (£27.19 per sq ft per year) in mind, let’s calculate how much a self-storage unit could cost you based on the size you rent. Your actual price may vary, so take these as estimates.

While these numbers may give you a rough idea of how self-storage costs, it’s also worth keeping in mind that other factors will influence the cost of your contract, such as length of time, your location, and the type of unit you have.

We’ve covered these in more depth below.

Length of Time

How much your self-storage will cost is determined by the length of time you need your unit for.

Typically, storage facilities will have set fees for a week, month, two months etc, and facilities that offer long term storage may have an annual fee as well.

Storage costs will be cheaper per month the longer your contract is for (e.g. a year-long contract will be cheaper per month than paying for one month at a time without a contract), so it’s worth having a good idea of how long you will need your storage unit for in order to give you the best deal.


The location of the storage facility will also have an impact on the total cost to rent a unit. Typically, the closer a self-storage facility is to a city centre, the more expensive it is going to be.

Essentially, you’ll pay for the convenience of having a facility in close proximity.

Likewise, there are considerable variations on price in the North versus the South of the country (with the North typically having lower costs), while London is considerably more expensive than any other location.


Finally, you’ll also want to consider the replacement value of the items you are storing in your storage facility, as this will add to the cost of your storage insurance.

Self-Storage Insurance Costs

For many self-storage facilities, having storage insurance is a mandatory requirement. However, that doesn’t mean you have to purchase your insurance directly through your provider.

We found that most customers save almost three times the amount on self-storage insurance when shopping with a third-party insurer such as Surewise, rather than using a self-storage provider directly.

Our policies are designed to be scaled to suit your needs, so make sure you have an accurate idea of the total replacement value of the items you are looking to put into storage to keep your policy valid without over-paying.

Other Things To Consider:

When deciding where to store your belongings, you’ll want to bear the following things in mind:

These features will all affect the price of your storage unit. The more secure a facility is and the more convenient they’re services, typically the higher the cost.

The trade-off is that you want a secure, safe facility that has the necessary measures in place to keep your belongings safe. A cheap facility may be able to cut costs because of poor security measures, which not only puts your items at risk of incidents such as theft and fire, but could potentially invalidate your insurance policy.

Deals and offers

Keep in mind that you may be able to save money on the cost of self-storage if the facility you are looking at has deals on. For example, some providers may provide a cheaper monthly discount if you sign up for an annual contract.

Monthly vs Annual Payments

Many businesses provide a discount for annual payments over monthly payments. If you know that you are going to need your belongings stored for a considerable amount of time, consider paying the annual fee to cut down costs.


Does the self-storage facility provide a transport service to get your belongings to the facility? If not, you will need to add in the additional cost to hire a moving van if required.


If you have a number of valuable possessions you need to put into storage, the quality of the company you go with will be an important factor. You’ll want a facility with units that are raised off the ground to avoid damage from damp or flooding, perhaps climate-controlled units, excellent security features, and limited access to the public.

The higher the quality of self-storage service, the higher the price you’ll be required to pay – but for the sake of ensuring the safety of your belongings, it may be worth it.

The cost of self-storage depends on many variables related to both your needs and the facility that offers self-storage units.
