20ft Used Storage Containers
20ft used storage containers are steel containers designed for secure, weather-resistant on-site storage in the UK. Unlike shipping-approved units, they are sold for static storage use only, which makes them a more cost-effective option for sites, farms, businesses, and domestic properties that do not need a valid CSC for export or transport.
What Is a 20ft Used Storage Container?
A 20ft used storage container is a former shipping container that has been repurposed exclusively for static storage use.
A 20ft used storage container gives buyers the strength and security of a steel container without paying extra for shipping certification they do not need.
Unlike used shipping containers:
- These units do not come with a valid CSC
- They are not suitable for export or transport by sea
- They are sold purely for on-site storage
Structurally sound and secure, they are ideal where shipping certification is unnecessary.
Why Buy a 20ft Used Storage Container Instead of a Shipping Container?
For many buyers, paying for shipping certification offers no benefit.
A 20ft used storage container is the right choice if you:
- Need secure, dry storage
- Do not plan to ship goods internationally
- Want the lowest upfront cost
- Are using the container in a static location
Removing shipping certification keeps costs down without compromising storage performance.
If you need a 20ft container with a valid CSC for shipping or export use, view our 20ft used shipping containers instead.
Typical Uses for 20ft Used Storage Containers
These containers are widely used across the UK for:
- Construction site storage (tools and machinery)
- Business premises (stock, equipment, documents)
- Agricultural and farm storage
- Allotments and rural sites
- Garden and domestic storage
- Sports clubs, schools, and community groups
A 20ft used storage container is one of the most practical options for buyers who need secure on-site storage without paying for shipping certification.
Condition, Grade and Appearance
20ft used storage containers are sold for function, not appearance.
You should expect:
- Dents and cosmetic wear
- Signs of previous repairs
- Surface rust patches
Every unit is supplied as:
- Structurally sound
- Secure
- Guaranteed wind and watertight for 12 months
Cosmetic wear is normal on a used storage container and does not stop it performing well as secure storage.
If you want a cleaner-looking unit with fewer cosmetic marks and a longer expected lifespan, see our 20ft one-trip containers.

How Much Does a 20ft Used Storage Container Cost?
A 20ft used storage container in the UK typically starts from around £850 + VAT, with final price depending on condition, depot location, and delivery distance.
A 20ft used storage container is usually cheaper than a shipping-approved unit because it is sold for static storage use only and does not include a valid CSC for export or transport.
Final pricing can vary based on:
- Container condition
- Depot location
- Delivery distance
- Access and offloading requirements
- Optional extras such as repainting, lock upgrades, or electrics
A 20ft used storage container is often the lowest-cost way to buy secure steel storage when shipping approval is not required.
Security & Durability
20ft used storage containers are built from heavy-duty steel and are widely used where security matters more than appearance.
They are well suited to storing:
- tools
- machinery
- business stock
- agricultural equipment
- household goods
- event equipment
A fitted lockbox helps protect the padlock from direct attack, which is one reason steel storage containers remain a popular alternative to timber sheds and lightweight storage units.
A steel storage container offers a far higher level of physical security than most domestic sheds or basic outdoor storage units.
Optional Extras & Modifications
20ft used storage containers can be adapted for improved usability, including:
- Repainting for improved appearance and corrosion protection
- Electrical fit-outs and lighting
- Racking and shelving
- Insulation or condensation control
- Security upgrades and lock systems
- Branding and signage
They are also frequently used as the base for simple conversion projects where shipping approval is not required.
If you are deciding whether a repaint is worth it, read Used 20ft Container Before and After Painting. It shows what painting can improve visually, what it will not change, and when the extra spend makes sense.
Delivery & Site Access Considerations
Delivery requirements are similar to other 20ft containers, so suitable access and a firm, level base are important.
Delivery vehicles may include:
- Rigid HIAB lorries (approx. 39ft long)
- Articulated lorries (up to 65ft long)
Before delivery, buyers should consider:
- Firm, level ground
- Clear access for turning and offloading
- Adequate overhead clearance
- Whether the container will sit level once placed
A container that is not level can become harder to open and close properly over time.
If you are unsure whether your site is suitable, our team can advise before delivery.
