What Can You Store in Self Storage Units?

When it comes to renting a storage unit, most people quickly realise just how valuable that extra space can be. Whether you're moving house, growing your business, or simply trying to free up space at home, self storage can be a lifeline. But one of the first questions that often comes up is simple: what can you store in self storage? The answer is broader than most people expect and also a bit more nuanced.

In this guide, we’re breaking down exactly what you can and can’t store in self storage, based on UK laws, industry best practices, and our own experience at Blue Box Storage. We’ll also share real-life examples, tips for packing and organisation, and insights into how self storage works at our secure Doncaster facilities.

Why Knowing What You Can Store in Self Storage Matters

It's easy to assume that anything lying around your home or office can go into a storage container – but that’s not always the case. While self storage offers a flexible solution for a wide range of needs, there are some important limitations you need to be aware of for legal, safety, and insurance reasons.

Understanding what can you store in self storage helps you avoid complications, ensures your belongings are protected, and makes your rental experience smoother overall. It’s also key to making the most of the unit you’ve chosen, especially if you’re planning to rent for the long term.

Common Household Items You Can Store in Self Storage

One of the most frequent questions we get at Blue Box is: Can I store my furniture, kitchenware, or seasonal items? The answer is yes – these are some of the most popular uses for storage units.

If you’re downsizing, preparing for a renovation, or just trying to declutter, storing household furniture is one of the most practical solutions. Everything from sofas and tables to bed frames and wardrobes can be safely stored, provided they're clean and dry when packed.

Homeowners often store excess kitchen appliances, small white goods, spare chairs, or seasonal decorations they only use once a year. Our guide to decluttering dives deeper into this lifestyle choice, helping you maximise your living space by moving non-essentials off-site.

You can also store boxed-up clothing, shoes, hobby materials, photo albums, suitcases, and books. If you’re not sure how to preserve the condition of textiles and paper over a long period, check out our guide to storing clothes.

Furniture and White Goods: Storage Advice

If you’re wondering what can you store in self storage from the bulky end of your home, furniture is usually top of the list. Sofas, armchairs, dining tables, and wardrobes are all suitable for storage, especially when disassembled where possible. At Blue Box, our furniture storage solutions are perfect for keeping large, awkward pieces safe while you redecorate or move.

When it comes to white goods like fridges, washing machines, or dishwashers, these can also be stored as long as they are fully drained, cleaned, and dry. Any leftover water can cause mould or damage, both to your appliance and to anything stored nearby.

What Can You Store in Self Storage for Business Purposes?

Business owners often have even more to gain from storage units. If your workspace is cluttered, you’re running an eCommerce business, or you need space for tools and supplies, self storage can help keep things organised and secure.

For example, online retailers often use our units to store excess inventory or seasonal stock. This is covered in more detail in our blog on eCommerce business storage, which explores how local traders can use Blue Box to avoid overfilling their home or office space.

Self-employed tradespeople often ask what can you store in self storage when it comes to tools, ladders, workbenches, and equipment. The good news is that our secure tool storage options are designed specifically with trades and mobile businesses in mind.

Documents, promotional materials, office furniture, and archived records are also commonly stored. Our document storage service ensures paperwork stays safe, accessible, and compliant with data protection requirements.

Vehicle Storage: What’s Allowed?

Vehicle storage is a common question and again, the answer depends on a few factors. At Blue Box Storage, we offer dedicated car storage and vehicle storage solutions, including for motorbikes, classic cars, and commercial vans.

But there are important conditions. Vehicles must be taxed, insured, and in working order. You can’t store vehicles in a general-purpose container unless they’re registered with us for this specific use, and the unit is appropriately ventilated. For caravans or larger vehicles, we also have caravan storage options available.

What Can You Store in Self Storage While Moving?

Moving house is one of the biggest triggers for using storage. People often don’t realise how helpful it is until they’re mid-move, surrounded by boxes and stressing about timelines. We’ve covered this topic in our moving house storage blog, but it’s worth highlighting here as well.

During a move, you can store everything from packed-up furniture and appliances to decorative items, fragile heirlooms, and children’s toys. Just make sure everything is properly boxed and labelled so it’s easy to retrieve when you need it.

Our Doncaster facility offers secure, accessible storage that’s ideal for short-term storage or longer contracts, depending on how your move progresses.

Items You Can’t Store in Self Storage

Understanding what can you store in self storage also means knowing what’s not allowed. To ensure the safety of your belongings (and those of everyone else), there are some firm rules around restricted items.

You cannot store anything flammable, explosive, or toxic. That means petrol cans, gas cylinders, fireworks, paint thinners, and industrial chemicals are strictly prohibited. These items pose a serious fire risk and may violate local laws and insurance policies.

Food and perishable goods are also not allowed. Even tinned or packaged items can attract pests if they degrade over time, which is why we ask all customers to avoid storing anything edible. Similarly, plants, animals, and anything living cannot be stored under any circumstances.

Weapons, firearms, and ammunition are forbidden. So are stolen goods, illegal items, and counterfeit products.

And while it might seem obvious, human remains or biological samples are not allowed – though if you’re interested in some of the more bizarre things found in storage, check out our blog on the storage facility used as a morgue.

How to Tell If Your Item Is Allowed

If you’re ever in doubt, our team is happy to help. We’ll always advise you before you move in whether something is permitted, and we’ll recommend the best way to store your belongings securely.

As a general rule, if an item is flammable, alive, illegal, or perishable – it probably doesn’t belong in storage. If it’s boxed, dry, legal, and non-hazardous – it probably does. But that still leaves plenty of room for confusion, which is why we suggest speaking to us directly if you’re unsure.

How to Pack Items for Long-Term Storage

So now that we’ve answered what can you store in self storage, let’s briefly look at how to pack it. Proper packing is key to protecting your belongings, especially for long-term storage.

Make sure all items are clean and dry before storage. Use strong, sealed boxes to prevent dust and moisture damage. Wrap delicate items in bubble wrap or cloth. Label boxes clearly and keep an inventory list to make retrieving items easier later on.

If you’re storing furniture, consider using protective covers to prevent dust and scratches. Disassemble where possible to save space and make handling easier.
