The story of
blue self storage

One small unit for man – one giant leap for storage!

We opened our first facility in 1988 at Wentloog Corporate Park, and the demand for affordable self storage has grown ever since!

Our team have grown with us from the beginning, and several of our staff have been proudly serving our customers for decades.

Our customers are our utmost priority, and we’re privileged to have been providing smart, affordable and secure storage in Cardiff for 3 decades and counting. Our new locations include Bristol, Treforest, Rogerstone, Gloucester, Bridgend, Tyneside and Aberdeen.

Whatever you need to store, we store

Our Wentloog site was the first in South Wales to be awarded the prestigious Platinum CaSSOA award for achieving the highest recognised levels of storage for caravans, boats and motorhomes, and we’re also proud members of the Self Storage Association.

Our self storage facility is here to help you ‘open up your life’ – add space, remove stress. That’s good maths!

So, whether you’re storing home furniture, vehicles, a caravan or something else entirely, our facilities come with 24/7 access and security as standard.

Why choose blue self storage

Storage solutions for whatever you need. You might be storing freight, cars, office furniture, camper vans or ancient family heirlooms – whatever it is, we’ve got you covered.

Our vast site means we can offer the types of storage other providers can’t. And with our expert team on hand at all times, we’re here to help you make the most of your storage.

Security you won’t find anywhere else

We strive to deliver the highest level of security possible, with 24/7 monitored CCTV surveillance, guard patrols with dogs and alarmed perimeter fencing.

We’re the ‘Fort Knox’ of self storage in Cardiff, with an in-house security team who work around the clock to protect our customers’ belongings. Our entire Wentloog facility is accessed via a guarded entry-point that requires photo ID, so we can monitor access 24/7.
