Buying a shipping container is simple once you know what to look for. The right choice depends on what you are storing, how much space you have, your budget and how long you need the container to last. This guide walks you through how to choose a shipping container in seven straightforward steps.
1. Decide what the container is for
Start with the job. The use decides almost everything else:
- General storage for a home, farm or business: a standard steel container is usually ideal.
- Site accommodation: look at container offices, canteen units and steel anti-vandal cabins.
- Chilled or frozen storage: choose a refrigerated container.
- Exporting goods: you need a cargo-worthy container with a valid CSC plate.
- A conversion project, such as a workshop, cafe or garden office: a new (one-trip) high cube is usually the best starting point.
2. Choose the right size
Work out roughly how much you need to store, then add a little extra for access and future needs. As a guide:
- 10ft: garden and domestic storage, small trades, tight spaces.
- 16ft: a good in-between size, often with a roll-up door.
- 20ft: the most popular all-rounder for homes, farms and businesses.
- 40ft: the most space for the money, ideal for stock, machinery and large projects.
See our shipping container sizes and dimensions guide for exact measurements.
3. Standard height or high cube?
High cube containers are 30cm taller than standard units. Choose a high cube if you plan to fit racking, insulate the walls and ceiling, or work or stand inside the container for long periods. For everyday storage, standard height is fine and usually cheaper.
4. New (one-trip) or used?
This is the biggest factor in price. A new or one-trip container has made one voyage and looks almost new. A used container costs less but shows dents, patched paint and surface rust. For storage, a good used wind and watertight container is excellent value. For a conversion, a visible location or a long working life, a one-trip container is often worth the extra.

5. Pick the right door configuration
- Standard doors at one end suit most storage.
- Double door (tunnel) containers open at both ends for easy access to everything inside.
- Side-opening containers open along the full length, ideal for workshops, retail stock and events.
- Roll-up doors give quick, ground-level access on smaller units.
6. Check your site and delivery access
Before you buy, make sure a lorry can reach your site and that you have a firm, level base ready. Check for overhead cables, narrow gateways and soft ground. If access is very difficult, a flat pack container can be carried in pieces and assembled on site. Our delivery and installation guide explains what we need.
7. Think about security, accessories and permissions
Add a lockbox and a high-security padlock to protect your container. Consider vents to reduce condensation, and racking and shelving to make the most of the space. Finally, check whether you need planning permission. Our guide to planning permission for containers explains the basics.
Quick buying checklist
- What will you store, and how much?
- Which size and height fit your site and your contents?
- New, one-trip or used?
- Which door layout do you need?
- Can a delivery lorry reach the site, and is the base ready?
- Do you need planning permission?
- Which accessories will you add?
How to choose a shipping container: final checks before you buy
Before you pay, run through a final set of checks. Confirm the internal dimensions against what you plan to store, check that the door position works with your access, and ask for the container’s condition in writing, with photos if you cannot visit. If the container will sit on your land, the Planning Portal explains when permission may be needed, and your local council can confirm what applies to your address.
It also helps to compare quotes like for like. Ask what is included in the price, such as delivery, offloading and any lock fitted, and whether the quote covers a crane lorry or tail-lift delivery. A clear written specification makes it easier to decide how to choose a shipping container that fits your budget without paying for features you do not need.
Frequently asked questions
What is the best shipping container for storage?
For most people, a used or one-trip 20ft container is the best balance of space, price and practicality. If space is limited, choose a 10ft container.
Is it cheaper to buy or hire a container?
For short-term needs of a few months, hiring can make sense. For longer periods, buying is usually cheaper overall and the container keeps its resale value.
Can I put a container on grass?
It is best not to place a container directly on grass or soil. Use sleepers, concrete pads or compacted hardcore to keep it level and off damp ground.
