This year’s Canstar Blue survey has seen National Mini Storage take the Most Satisfied Customers Award for 2019, rated 5-stars for customer service, quality of service, convenient location and overall satisfaction.

What is a self-storage and what can I store?

Basically, self-storage lets you hire a space or unit that you can store your stuff in.  There’s not a lot to it! More interestingly, what can you store and what can’t you store?

Things you can generally put in storage include furniture, books, appliances, vehicles, clothes, sporting equipment and collectibles.  Now for things you can’t keep in self-storage – paint and paint thinner, solvents, petrol, medical supplies, fresh food, animal food, animals, plants, weapons and of course illegal substances or items. Needless to say, if it’s living, you can’t put it in storage.

Storage units have been used for many weird and wonderful things and amazingly, some people forget they have them.  Some of the more unusual contents of abandoned units have been:

  • James Bond’s submarine car. One unsuspecting man in 1989 paid less than $100 for a storage unit in the United States, and when he cut the bolts and opened his new unit the next day he found a white sports car covered in blankets.  He later found out that the car was one of the submarine cars driven by James Bond in The Spy Who Loved Me.
  • A human leg. It was not a normal day when a man who purchased a storage unit in 2007 at an auction found a meat smoker with a human leg inside it.  The original owner of the unit, John Wood, lost his leg in a plane crash in 2004. He was keeping it in storage but lost the unit when he fell behind in payments.
  • A rocket. During popular American TV show Auction Hunters, Allen Haff and Clinton Jones bid $1500 for the contents of a storage unit.  Later they found a NASA countdown clock and a NASA rocket. They sold these and NASA never asked for their rocket back.

So, assuming you’re not the owner of one of the above, what are other reasons people need a storage unit?

In Canstar Blue’s survey, 39% of respondents said their reason for using a self-storage unit was to store things while they were ‘between’ homes. This was followed by 34% of respondents who said they didn’t have enough space in their house, and 12% who were traveling overseas.

Things to look out for when looking for a storage unit

T’s and C’s. Make sure the storage unit facility’s rules and regulations suit your wants and needs.  Different people have different wants.  Is it dry? It’s best not to invest in a damp space to store your things, especially if your belongings are vulnerable to moisture. You wouldn’t want a collection of books sitting in a wet room. Make sure the storage unit you’re looking at is a suitable size for whatever you’re planning on putting in it, as well as having a trustworthy lock. Make sure your storage unit is lockable and is locked.  As you can imagine, storage units are often full of goodies which attract burglars.

How long do people use self-storage units for?

Surprisingly, not as long as you might expect.  When asked how long people have used their self-storage unit, for the majority of people (55%) it was up to six months.  Most people (74%) use storage units for less than a year. This is likely because the most popular use for self-storage seems to be founded from temporary situations – such as being between homes, renovating, travelling and relationships ending. While some people use storage units long term, this is often to store valuables, collectables, heirlooms, and things that don’t need to be used on a daily, or even yearly basis.

What happens if you abandon your self-storage unit?

Specific details may vary with different storage providers, but here is an overview of what usually happens.  When a storage unit is considered abandoned, the contents become property of the storage facility. It doesn’t matter if the contents are worth more than the entire facility itself, that’s how it works, so make sure you don’t forget about yours!  Of course, there is a period of trying to contact the owner, but if they are unable to make contact, the facility will often conduct an auction for the contents in an attempt to cover the rent arrears. The auction’s time and place have to be publicised and the owner will receive a certified notification that this will be happening.  So, rest assured, your unit will not be auctioned off without you knowing about it.

And, what did the people we spoke to rate about their storage unit experience?

Value for money

This subject is somewhat subjective and different people may have different experiences. That said, this is a fairly good ‘rule of thumb’ guide to follow if you’re in the market.

Kiwi Self Storage registered 5-stars, National Mini Storage scored 4-stars and Kennards, National Storage and Storage King scored 3-stars.

Customer service

Although the customer service for a storage facility isn’t going to be a daily need, it’s nice to know that it’s there when you need it.

National Mini Storage received 5-stars, National Storage and Kennards were rated 4-stars, while Kiwi Self Storage and Storage King were rated 3-stars.

Quality of storage

The reason why you’ve stored your possessions is because you want to keep them safe. This means clean and dry too – so, it’s always worth checking out the storage units before you sign the contract. Be aware of water stains, or a damp smell in the air, as this could be a sign that the unit is not weather tight.

National Mini Storage and Kennards were awarded 5-stars in this category, National Storage and Storage King gained 4-stars and Kiwi Self Storage scored 3-stars.


Being able to gain easy access to your unit is pretty important.  Having limited hours of opening may not fit well with your availability, so make sure that if you need access outside of regular hours, your storage facility provides that service.

Kennards was rated 5-stars, National Mini Storage, National Storage and Kiwi Self Storage scored 4-stars, with Storage King registering 3-stars.

Safety and security are important – if you’re paying for a storage service, you want it to be safe and secure. Kennards brought in the 5-stars for this category, with National Mini Storage and National Storage receiving 4-stars. Kiwi Self Storage and Storage King were rated 3-stars.

Convenient location

It’s no good paying a bargain price but having to drive hours to get to your unit, especially if you will be wanting regular access. Check out the locations on the websites before you’re tempted to sign up, to make sure it’s going to work for you.

National Mini Storage was again the only operator awarded 5-stars in this category, with Kennards rated 4-stars and the remaining operators earning 3-stars.
