Not everything you own belongs in a storage unit. While these spaces are convenient for clearing clutter, moving house, or managing business stock, they do come with rules. Some items are perfectly safe to keep there, while others could risk your safety or break the law.
Whether you’re downsizing, decluttering, or running a business, understanding what goes in and what absolutely doesn’t is essential. Keep reading to make sure your next move is smart and secure.
Safe Items to Store
Self storage units are ideal for everyday household items, whether you’re between homes or just trying to free up room. You can confidently store furniture, white goods, and seasonal decorations. Electronics like TVs and gaming consoles are welcome, as long as they’re dry, cool, and protected from impact.
If you’re a business owner, storage units are great for keeping office supplies, files, and even bulk stock. Many small retailers use self storage in Wandsworth to manage overflow inventory and reduce clutter in their main location.
Sports equipment, hobby collections, and musical instruments can also be stored, provided they’re packed carefully. Even vehicles such as motorbikes or classic cars may be allowed, depending on the unit type and insurance.
What’s Off Limits?

While storage may seem like a secure space for everything, some items are simply not allowed due to legal or safety concerns.
Food is a common example. Any perishable or open food item is likely to attract pests and mould. Similarly, living things, such as plants, pets, or animals, cannot be stored. These units are not ventilated or climate-controlled in the way living organisms need.
Flammable or hazardous materials like petrol, fireworks, and cleaning solvents are strictly forbidden. These substances pose major risks of fire or explosion, particularly in shared or closely packed facilities.
Legal and Security Restrictions
You’re not allowed to store anything that’s stolen or illegal. That includes counterfeit items, unlicensed firearms, or drug-related products. Reputable storage facilities will include this in their terms and may inspect units if they suspect misuse.
Storing cash, rare jewellery, or family heirlooms is also discouraged. These are better kept in a safety deposit box, not a unit with shared access points. Most facilities limit their liability on high-value items unless you purchase specialist cover.
Wet or damp items are another problem. These can cause mildew or water damage to your other stored goods. Make sure everything going into storage is clean and dry.
Wrapping Up
Knowing exactly what to store and what to keep out will save you stress and money. It also ensures you remain compliant with your storage provider’s terms. Before moving your items in, double-check the rules, and when in doubt, ask. Storage is meant to make life easier, not introduce unnecessary risks. Choose wisely, pack smart, and keep your belongings safe the right way.
