New and Used 40ft Shipping Containers for Sale UK

A 40ft shipping container is the right choice when you need a large, secure space and have the site access to receive it. It offers around twice the length of a 20ft unit, so it suits bulk stock, building materials, plant, agricultural equipment, archive storage, warehouse overflow and export cargo.

Acorn Containers can help you compare new one-trip and used 40ft shipping containers for sale across the UK. The best option depends on what you need to store, how long you need the unit, how it will look on site, whether it may be modified and what delivery route is available.

Why choose a 40ft shipping container

A standard 40ft steel container gives a large enclosed storage area in one unit. For businesses handling volume rather than small, regular access loads, it can be a practical way to add space without committing to a permanent building.

The length is useful for long materials, palletised goods, seasonal stock and equipment that would be awkward to split across smaller containers. It also reduces the number of units on site, which can make the compound easier to manage where space, security and access routes are planned properly.

• Large internal volume: A standard 40ft container offers around 67.7 m³ of internal space.
• Strong steel shell: Corrugated CORTEN steel panels help resist weather and general site wear.
• Wide end doors: Double doors at one end allow loading by hand, pallet truck or forklift where the ground and loading method are suitable.
• Timber floor: A 28 mm marine-grade plywood floor on steel crossmembers supports many common storage and freight loads.
• Flexible use: A 40ft unit can suit commercial storage, site work, export and some modification projects.

If your site has restricted access, compare the smaller 20ft shipping container for sale. For top-loaded cargo, machinery or awkward items that cannot pass through end doors, look at 40ft open-top container sales.

40ft shipping container dimensions

Check the container dimensions against both the site and the items you plan to load. The door opening is slightly smaller than the internal width and height, so tall or wide equipment needs to be measured at its widest point, including packaging, handles, guards and lifting frames.

A 40ft high cube container may be useful where height is the limiting factor. High cube variants have an external height of 2.89 m, or 9 ft 6 in, giving extra headroom for taller stock, racking or equipment. Check availability and suitability before planning around a specific variant.

Buying or hiring a 40ft container

Buying normally suits long-term storage, export, modification projects and sites where the container will become part of the operating setup. Ownership gives you more control over future use, repainting, lining, shelving and relocation, subject to the condition of the unit and any planning, lease or site restrictions.

Hiring can work better for temporary needs. Construction phases, refurbishments, seasonal stock peaks and short projects often need a large container for a defined period, then collection once the work is complete. Hired containers need to remain accessible for collection and should not be altered unless agreed in advance.

The cost of either route depends on factors such as size, type, condition, hire length, delivery distance, access, crane requirements, collection and modifications. A clean one-trip unit may suit a visible site or customer-facing area, while a used wind and watertight unit can be a sensible choice for robust storage where appearance is less important.

New one-trip and used condition grades

Condition grades help narrow the choice, but they should not be treated as guarantees without inspection and confirmation. Age, repairs, floor wear, door operation, certification and shipping-line acceptance can vary between individual units.

New one-trip containers

A one-trip container is usually described as new because it has been manufactured overseas and shipped to the UK with a single cargo load. It should normally be cleaner than a used container, with less visible wear, better paintwork and a tidier floor. It may still show small marks from manufacture, handling and transport.

Used wind and watertight containers

Wind and watertight, often shortened to WWT, means the container is intended to keep out wind and rain when the doors, roof, seals and walls are sound. Used WWT containers often show dents, scratches, surface rust and previous repairs. For site storage, that cosmetic wear may not matter if the container is dry, secure and structurally suitable.

Cargo-worthy, IICL and CSC-plated containers

Cargo-worthy units are assessed for freight use, but a shipping line or freight forwarder may still have its own acceptance checks. IICL is a stricter inspection and repair standard used in parts of the container leasing market. A CSC plate is the safety approval plate used for international transport. If the container is going back to sea, check its CSC status and acceptance before loading cargo.

For more detail on these terms, see the shipping container condition guide.

Delivery access and 40ft container placement

A 40ft container needs more delivery planning than a smaller unit. The vehicle is long, the load is heavy and the crane needs enough working space to lift and place the container safely. Confirm access before arranging delivery, especially on farms, construction sites, industrial estates, narrow lanes and domestic properties.

Most customers should check the access route from the public road to the drop point. Measure the gate or entrance, note tight turns, check for parked vehicles, look at ground strength and identify any overhead obstructions. Cables, branches, building eaves, signs, lighting columns and scaffold can all affect the lift.

• Provide clear access for a large delivery vehicle and allow turning or reversing space.
• Check the drop area is firm, level and suitable for the weight of the container.
• Allow room for the lorry’s stabiliser legs where HIAB delivery is used.
• Decide the door orientation before delivery so the doors open the right way for loading.
• Keep the container accessible if it may need to be collected, moved or replaced later.
• Send access photos and site notes where the route or drop point may be difficult.

A container placed on soft grass, mud or uneven ground can settle and twist. This is known as racking. When the frame is out of square, the doors can become difficult to open, and the seals may not close correctly. Supporting the four corner castings on level concrete pads, paving slabs or suitable timbers helps keep the frame aligned and allows airflow below the floor.

For more detail on offloading and access checks, see HIAB container delivery.

Security, storage layout and condensation

A 40ft container gives a strong steel enclosure, but security still depends on the lock, location and how the site is managed. A lockbox protects the padlock area from easier attack. Door locking bars, hinges and seals should operate properly, and high-value contents should be supported by sensible site security such as lighting, fencing and controlled access.

Condensation needs planning on long-term storage jobs. It forms when moist air meets cold steel, then settles on the roof, walls, floor or stored items. Damp timber, wet pallets, unsealed liquids and poor airflow increase the risk. A large container packed tightly from end to end can trap moisture and make inspections harder.

• Load dry goods and avoid putting wet materials into a closed container.
• Lift stock off the floor on pallets to improve airflow.
• Keep vents clear and avoid stacking goods hard against the walls.
• Use desiccants where goods are sensitive to moisture.
• Consider lining or insulation where temperature change is likely to damage the contents.
• Plan an aisle or access route if items need to be reached regularly.

For tool storage, stockrooms and warehouse overflow, racking can make better use of the long internal space. Heavy loads should be spread sensibly, and any forklift loading should account for the floor, ramps, ground and safe working method.

The guides to shipping container security and racking for shipping containers may help when planning the internal layout.

Export checks and paperwork

A 40ft shipping container can be used for export when the unit, cargo and documents meet the requirements of the shipping line, freight forwarder, customs agent and destination country. Do not assume a used storage container will be accepted for sea freight without current checks.

Before loading, confirm CSC status, payload limits, verified gross mass, cargo suitability, packing method, insurance, customs declarations, duties, taxes, prohibited goods and responsibility for delays. Detention, demurrage and storage charges can arise where containers or documents are not ready at the right time.

Incoterms 2020 can help define where cost, risk and responsibility transfer between buyer and seller, but they need to match the sales contract and freight arrangement. This page is not legal, tax, customs, insurance or freight advice. Check with the relevant authority, freight forwarder, customs agent, shipping line, insurer or adviser before dispatch.
