What makes Attic different

Located in easily accessible  reas of London, Attic Self Storage have a range of large storage units available for all your self storage needs. Our largest storage unit can hold the equivalent of three double garages, and each of our big self storage units can be used for business or personal use; with 24-hour access included as standard.

Security for Our Big Self Storage Units

All of our large storage units are highly secure.

With a perimeter fence surrounding our facilities, each of our large storage units are also individually alarmed and monitored by CCTV at all times.

Your safety is paramount, so the sites holding our big storage units are brightly lit and airy. The sites have been designed this way so you feel safe visiting your unit and you can be assured that anything you store with us is being kept safe and secure.

You will be given a unique PIN to access our facility and a padlock on the unit that only you are able to access, and so anytime you need to get something from your unit you have the peace of mind that you are safe to do so and that your unit will not be accessed by anyone you don’t authorise.

How Much Storage Space Will I Need?

If you’ve not used a storage unit before, the unit sizes might be hard to visualise. We have created a handy storage calculator to help you figure out exactly what you need.


We want you to get a storage unit that fits your needs perfectly instead of wasting money on storage you don’t need or, conversely, not having enough storage space.

Try out our storage calculator 

For example, a 300 square foot storage unit will hold around 10 rooms of furniture, perfect for moving from a 5-bedroom house or using as a business stock room.

Ranging from 10-500 square foot, our range of large storage units, across London, can accommodate your needs.

Once you’ve used our storage calculator to work out which size unit is right for you, you can get an instant quote online and one of our customer service representatives will contact you to discuss your quote and your storage needs.
