20ft Used Shipping Containers
20ft used shipping containers are ISO-built steel containers that have previously been used in international transport and are now repurposed for storage or shipping use. Supplied wind and watertight with a 12-month guarantee and a valid CSC for shipment, they offer a cost-effective, durable solution for storage, export, and conversion projects across the UK.
What Is a 20ft Used Shipping Container?
A 20ft used shipping container is a standard ISO container that has completed multiple cargo journeys before being decommissioned from shipping service. Once removed from active fleets, these containers are inspected and prepared for resale.
They remain structurally sound, secure, and weather-resistant, making them one of the most popular and versatile container options in the UK.
For buyers prioritising value over appearance, used containers offer excellent long-term practicality.
Why 20ft Containers Are the Most Popular Size
20ft containers strike the ideal balance between capacity and site footprint, which is why they’re the most widely used container size.
They are commonly used for:
- Self-storage
- Building sites (tools and machinery)
- Gardens (shed replacement)
- Business premises (stock, equipment, documents)
- Sports clubs and schools
- Farms and allotments
Where space is limited but security is essential, a 20ft container is usually the right choice.
Condition & Grade Explained (Important)
Used 20ft containers are not cosmetic-grade units.
You should expect:
- Dents and surface wear
- Evidence of previous repairs
- Cosmetic rust patches
However, every unit supplied is:
- Structurally sound
- Secure
- Guaranteed wind and watertight for 12 months
These containers are sold for function and durability, not aesthetics.
Shipping Certification (CSC)
Our 20ft used shipping containers are supplied with:
- A valid CSC for 12 months, suitable for export shipping
The CSC can be extended if required, making these containers suitable for buyers who need short-term shipment approval without the cost of a one-trip unit.

Delivery & Site Access Considerations
Shipping container delivery requires suitable access.

Discuss access in advance to avoid delivery issues.
