Buyer's guide

Storage container vs shipping container: which do you need?

Both are lockable steel boxes that keep your kit dry and secure. One is a purpose-built site store with colour choice and delivery included; the other is an ISO freight container that gives you the most secure space per pound you can buy. We sell both, so here is the honest comparison.

Prices are our live catalogue figures, checked July 2026, ex VAT. Storage container prices include UK flatbed delivery; shipping container delivery is quoted by postcode.

What actually differs

A shipping container is built to the ISO freight standard: heavy corten steel, CSC plated for sea transport, 8ft wide, 8ft 6in tall (9ft 6in for a high cube), with cargo doors at one end. Ours are brand new one-trip units that have made a single cargo journey from the factory, so they arrive in as-new condition with a 12-month watertight warranty.

A storage container is a lighter steel box designed purely for secure storage on the ground. It gives up the freight certification and the heavyweight build, and in exchange you get things a freight box cannot offer: sizes from 5ft and 6ft upwards, a choice of RAL colours, fork pockets on most sizes so you can reposition it with a telehandler, and a lower weight that makes handling far easier. Our smallest weighs 436kg; a 20ft shipping container weighs about 2.2 tonnes empty. Browse the range here.

Neither is "better". They solve the same problem at different points on the size, handling and budget scale.

Price per square metre

This is where the shipping container earns its keep. A new one-trip 20ft shipping container is £2,195 ex VAT for 14.8 m². A 20ft storage container is £4,400 delivered for the same footprint. Even after you add HIAB delivery to the shipping container, it comes out around half the price per square metre, and the 40ft stretches that advantage further: nothing beats it on raw secure space per pound.

The picture flips at the small end. There is no such thing as a cheap small shipping container: a 10ft has to be cut down from a larger box or built new, which is why it costs nearly as much as a 20ft. If you need a compact store for a yard corner or a tight site, the 5ft to 8ft storage boxes occupy ground a freight container never could, at prices a freight container cannot reach.

When a storage container wins

When a shipping container wins

Rule of thumb: under 10ft, or moved often, or on show: storage container. 20ft and up, static, and space per pound is the priority: shipping container. At exactly 10ft, compare the pair: the shipping 10ft is cheaper to buy, the storage 10ft is delivered and easier to handle.

Common questions

Is a storage container the same as a shipping container?
No. A shipping container is built to the ISO freight standard in heavy corten steel with CSC certification for sea transport. A storage container is a lighter steel box designed purely for secure storage on the ground: easier to handle, smaller sizes, colour choice, but not certified for shipping.
Do shipping containers leak or get condensation?
A sound one-trip unit is fully wind and watertight, and ours carry a 12-month watertight warranty. Condensation is separate: any sealed steel box can form it depending on contents and how often the doors open. Ventilation, desiccant poles or lining keep it under control.
What ground do I need?
Firm and level, for either type. Concrete, tarmac or compacted hardcore are ideal; railway sleepers or concrete pads under the corners work on softer ground. For shipping containers the delivery vehicle also needs clear access; see the delivery page.
Can I move it later?
A storage container with fork pockets moves with a suitable forklift or telehandler. A shipping container is a crane job: plan its final position before delivery, or budget a HIAB visit for the move.
Are your containers new or used?
Everything on the site is brand new: storage containers straight from the factory, shipping containers one-trip (a single cargo journey, so expect at most minor transit marks).
