Who are the blue storage group?
Has that ever crossed your mind? Then you’re in the right place.
We’re not just a storage company, we’re part of something bigger. Built on teamwork, growth and giving you a better experience every time you interact with us.
So what is the blue storage group
The blue storage group was born from a merger between blue self storage and Maltings Document Storage Solutions (MDSS). That’s right – two South Wales storage businesses decided to join forces and grow together. The result? A brand-new group that brings strength, scale and flexibility while still keeping all the things you love about each business.
MDSS, short for Maltings Document Storage Solutions, are specialists in secure document storage and information management. With decades of experience working with businesses across sectors like legal, healthcare and finance, they help organisations store, manage and retrieve important records safely and compliantly. Known for their expertise, reliability and people first approach, MDSS bring a wealth of knowledge that perfectly complements blue self storage within the blue storage group.
Both companies continue to operate under their own names, but now they share a bigger vision and greater opportunities for growth. By becoming a larger entity, the blue storage group can invest in better systems, explore new funding opportunities and expand into new regions across the UK.

The story behind the partnership
blue self storage has been growing its footprint across the UK, offering container storage for homes, businesses, vehicles and more with facilities in Cardiff, Tyneside, Bridgend and soon Gloucester. MDSS, on the other hand, brings over 40 years of experience specialising in document storage and management solutions for businesses across sectors like legal, healthcare, finance and more.
The leaders of both businesses believe they’re stronger together because the infrastructure needed to serve customers across different storage needs is actually more similar than you might think. That shared foundation makes it easier to innovate, improve services and evolve the way storage works for you.

What that means for you
So why should you care? Being part of the blue storage group means:

What’s next
