What Can You Store in a Storage Container?

It’s one of the first questions people ask us: “What can I actually put in one of these?” The honest answer is simpler than most people expect. A 10ft or 20ft steel storage container will hold almost anything that fits through its doors — furniture, tools, vehicles, paperwork, boxes of just about everything. But there are a few things that don’t belong in any storage unit, and knowing the difference before you start packing saves a lot of trouble.

Here’s the full rundown, based on what our customers in Manchester and Salford actually store with us every week.

The Short Answer: Almost Anything Dry and Non-Hazardous

If it’s solid, dry, legal and not alive, it can almost certainly go in. Containers were built to cross oceans — solid steel boxes designed to protect cargo on long sea journeys. Converted and maintained for self storage, they handle household goods, business stock and equipment with ease.

The main things that stay out are perishables, anything flammable or hazardous, and living things. We’ll cover those in detail below, because storing the wrong item can damage your own belongings — and in serious cases, put other people’s property at risk.

Furniture and Household Items

This is the bread and butter of container storage. Sofas, beds, wardrobes, dining tables, bookshelves, mattresses, white goods — all of it fits comfortably. A 10ft container (around 80 sq ft) holds roughly the contents of a one-bedroom flat; a 20ft (around 160 sq ft) takes a two to three-bedroom house.

A couple of practical tips: dismantle what you can (bed frames, table legs), stand sofas on end to use the height, and put mattresses in protective covers. Wooden furniture does best with a little airflow around it, so avoid packing everything drum-tight against the walls. Our furniture storage page goes deeper on preparing larger pieces, and our condensation guide explains how to keep soft furnishings in good condition during longer stays.

Tools and Trade Equipment

Tradespeople are some of our most regular customers. Power tools, hand tools, ladders, workbenches, site equipment and materials all store well in a container — it’s essentially a lockup you don’t have to share. A 10ft unit works well as a personal tool store; a 20ft handles the kit for a whole crew plus materials.

Keep petrol-powered tools drained of fuel before storing (more on fuel below), and keep an inventory list — when you own hundreds of tools, it’s easy to forget what’s in the back. See our tool storage for tradesmen page for the full picture.

Motorbikes, Bicycles and Other Vehicles

Bikes and motorbikes fit easily — a 10ft container holds two or three motorbikes with room for gear alongside. Classic cars, quad bikes and jet skis go in 20ft units. This is popular for winter lay-ups: the bike comes off the road in October and back out in spring, dry and untouched.

Prep matters here: clean the bike, stabilise or drain the fuel, disconnect the battery, and put it on a paddock stand if you have one. Our motorbike storage page covers the full winter-prep checklist.

Documents, Archives and Business Stock

Solicitors, accountants, letting agents and landlords store years of paperwork with us — contracts, certificates, compliance records. Archive boxes stack neatly, and a 10ft container holds a serious filing history. E-commerce sellers and small businesses use containers as overflow for stock, packaging and display equipment.

Paper and cardboard are the items most sensitive to moisture, so keep boxes off the floor on pallets or shelving and leave small gaps for air to move. Our document and archive storage page explains the setup in detail.

Seasonal and Occasional-Use Items

Christmas decorations, camping gear, garden furniture, winter sports equipment, suitcases, spare tyres — the things you use a few weeks a year but trip over the rest of the time. These are perfect container candidates because you only need access a couple of times annually, so they can live right at the back.

What You Can’t Store (and Why)

Every storage company draws these lines, and they’re there for good reason:

• Perishable food — anything that rots, smells or attracts pests. Tinned and sealed dry goods for a short stay are generally fine; fresh food never is.
• Flammables and fuels — petrol, diesel, gas bottles, paraffin, solvents and paint thinners. Drain fuel tanks before storing vehicles or machinery.
• Hazardous chemicals — pesticides, strong cleaning chemicals, asbestos-containing materials.
• Living things — no plants for long stays (they won’t survive without light and water), and never animals.
• Illegal items — self-explanatory, but worth stating.
• Wet or damp items — never put anything away wet. A damp tent or soggy cardboard box will cause problems for everything stored near it. Dry everything first.

When in doubt, ask us before you load up — a quick call to 07375 063637 settles it in a minute.

How to Pack a Container Well

What you store matters less than how you store it. The golden rules: heavy items at the bottom and toward the front, fragile items on top, everything labelled, and a narrow walkway down the middle so you can reach the back without unpacking everything. Fill gaps with soft items like duvets and cushions so nothing shifts.

Leave a small air gap between your belongings and the container walls — it makes a real difference to ventilation over a long stay. Our how to pack a storage container guide walks through the whole process step by step.

Which Size Do You Need?

As a rough guide: a 10ft container (from £25/week) suits a room or two of furniture, a couple of motorbikes, a serious tool collection, or a few dozen archive boxes. A 20ft container (from £40/week) handles a full house move, a classic car, business stock, or a whole-house declutter.

Our Salford yard is open 7 days, 9am–9pm, with 24/7 CCTV monitoring across the site. If you’re clearing out rather than moving, our declutter storage page is built around exactly that project.

The Bottom Line

For most people, the answer to “what can I store in a storage container?” is “pretty much everything you own.” Furniture, tools, bikes, documents, seasonal gear — if it’s dry and safe, it goes in. Keep fuel, food and hazardous items out, pack with airflow in mind, and a steel container will look after the rest.
