Shipping Container Storage vs Self Storage: Which is Right for You?

When you need extra storage space, you'll typically come across two main options: shipping container storage and self storage. Both can be excellent solutions, but they suit different needs, budgets, and situations. In this guide, we break down the key differences so you can make the right choice.

What is Shipping Container Storage?

Shipping container storage means renting a large metal container — typically 20ft long — to use as your own private storage unit. The container sits in a secure, fenced yard and you have exclusive access to it. Think of it as having your own private garage, but on someone else's land.

At Chock-a-Block Storage in Bexhill-on-Sea, our 20ft containers are positioned on a CCTV-monitored yard with drive-up access, so you can load and unload directly from your vehicle without any lifts, corridors, or trolleys.

What is Self Storage?

Traditional self storage facilities offer individual storage units inside a building — similar to a large locker or room. Units typically range from small cupboard-sized spaces right up to room-sized spaces. You access your unit through shared corridors, often using a lift.

Large national chains like Safestore and Big Yellow dominate the self storage market, but local independent operators also offer this type of storage across East Sussex.

Key Differences at a Glance

Space and Size

A 20ft shipping container offers approximately 33 square metres of floor space — roughly the same as a single garage. This makes it ideal for storing the contents of an entire home, significant volumes of business stock, or large items like furniture and equipment.

Self storage units tend to be more modular, starting from as small as 10 square feet and scaling up. If you only need a small amount of space, self storage can be more cost-effective. If you need a garage's worth of space, container storage usually offers better value.

Cost

Shipping container storage is almost always more affordable per square foot than traditional self storage. Self storage facilities in the South East of England typically charge a premium — particularly the large national chains — due to the high cost of their purpose-built buildings.

At Chock-a-Block Storage, our 20ft containers start from £150 per month with no hidden fees. Comparable space at a large self storage operator could easily cost two to three times that amount.

Access

Both options typically offer good access, but shipping container storage has a practical edge for bulky items. With drive-up access, you can pull your van or car right up to the container door. No lifts, no shared corridors, no trolleys required.

Self storage facilities usually require you to navigate a building — which can be frustrating when you're moving large furniture or heavy equipment.

Security

Both types of storage can offer excellent security, but the setups differ. Self storage buildings tend to have electronic access systems, alarm systems, and internal cameras. Shipping container storage yards are typically secured with perimeter fencing, CCTV cameras, and gated access.

At Chock-a-Block, our entire yard is monitored 24/7 by CCTV and the site is fully fenced and gated.

Flexibility

Self storage contracts can vary — some national chains lock you into minimum terms or charge admin fees to move. Container storage tends to be more straightforward, with flexible month-to-month terms and no long-term commitments.

At Chock-a-Block, there's no minimum contract period. You rent for as long as you need, and leave when you're ready — no penalties, no fuss.

Who Should Choose Shipping Container Storage?

• Home movers who need to store the contents of a house
• Businesses needing to store stock, equipment, or tools
• People doing home renovations who need furniture out of the way
• Anyone who needs large-volume storage at a competitive price
• People with large or bulky items who need drive-up access

Who Should Choose Self Storage?

• People who only need a small amount of space (e.g. a few boxes)
• Those who prefer a climate-controlled environment for sensitive items
• People who need very frequent access throughout the working day

The Verdict

For most people in East Sussex who need a practical, spacious, and affordable storage solution, shipping container storage offers better value and more flexibility than traditional self storage. The cost savings are significant, the space is generous, and the drive-up access makes loading and unloading far easier.
