Are Self-Storage Containers Secure? Your Safe Storage Guide

Buzz Carter 29th May 2026

When you store something important – whether it’s family furniture, business stock, or valuable tools – security is naturally top of mind. Self storage is now a hugely popular way to create extra space, used by thousands of households and businesses across the UK, with more providers than ever, it’s become even more important to check the security standards for whoever you trust with your possessions. 

So how secure is self storage really – and what should you look for when choosing the right provider?

How Secure Is Self Storage With The Space Program?

At The Space Program, security isn’t an add-on, it’s the foundation of everything we do. Our containers are built tough, and our sites are protected by multiple layers of security – so your belongings stay exactly where you left them.

Each customer has their own dedicated container, secured with a heavy-duty, saw-proof and pick-proof padlock that we supply as part of your rental. You hold the only keys, meaning you control access to your unit at all times.

On top of that, each of our facilities around the South West are designed to be safe to visit day or night, with floodlit container rows, CCTV coverage, and controlled gate access. It’s secure, straightforward, and gives you proper peace of mind.

Are Self Storage Containers Safer Than Other Storage Options?

In many cases, yes. Container self storage can be safer than keeping valuable items in places like garages, sheds, or vans. Those are often targeted by thieves, and they’re rarely built for proper security or weather protection.

Containers, on the other hand, are designed for hard conditions, we use containers made to travel the world on ships and keep sensitive goods dry and protected in extreme weather – making them a solid choice for secure long-term storage.

Plus, in our container storage facilities, units are separate – so risks like fire spreading between neighbouring units are far lower than in a shared indoor warehouse environment. (Containers are made from non-combustible COR-TEN steel, which is fire-resistant rather than fireproof.) 

So if your priority is robust protection, easy access, and clear security, containers are hard to beat.

What Security Does The Space Program Have At Its Facilities?

We encourage anyone comparing storage options to ask detailed security questions. Reputable providers will be happy to explain how they protect your belongings. At The Space Program, our security measures include:

  • High-security padlocks provided (with two keys) 
  • 24/7 CCTV monitoring across storage areas 
  • Floodlighting around container rows for visibility at night 
  • Controlled site access, including gated entry and customer access codes 
  • Staff presence and patrols during opening hours 
  • Industry professionalism, with standards aligned to best practice in UK self storage

We also verify customer ID at sign-up. That might feel like a small step, but it’s a big part of keeping sites secure for everyone.

What Is The Space Program’s Security Record?

We’re proud of this: The Space Program has maintained an unbeatable security record since we opened our first location in 2002.

Our security track record isn’t luck – it comes from consistently investing in proper security, using robust containers, and sticking to the basics that keep sites safe. When people trust us with their belongings, we take that seriously.

 

Container self storage can be an incredibly safe and secure option for business storage and personal storage – but only if you choose the right provider. Look for strong containers, solid locks, controlled access, lighting, CCTV, and a proven security record.
