You put your belongings in self-storage to keep them safe — protected against theft, vandalism, fire, and flood. Most modern facilities take security seriously, but that doesn't mean every unit is equally protected. Here's what to look for and where insurance fits in.
Fire is a serious threat
Fire spreads rapidly in storage facilities, and the consequences can be devastating. A 2021 fire at a Manchester storage site required 125 firefighters and 25 fire engines to bring under control — and many customers lost belongings that weren't insured.
Good security measures reduce the risk of arson and accidental fires, but they can't eliminate it entirely. That's why insurance matters even in well-run facilities.
What to look for in a secure facility
When choosing a storage provider, ask for a tour and ask questions. The best facilities won't mind — in fact, they'll expect it. Here's what a security-conscious facility should have:
- Secure perimeter fencing — bolt-cutter-proof and not easily scalable
- A locked gate with managed access — ideally staffed during opening hours
- CCTV cameras that are well-positioned, monitored, and working
- An alarm system linked to police or a reputable security company with a fast response time
- A night watchman or afterhours security presence
If a facility is reluctant to show you around or answer questions about security, that tells you something.
Securing your unit
Beyond the facility's own measures, there are steps you can take at the unit level:
- Buy the best padlock you can afford — bolt-cutter-proof, ideally a disc lock or shrouded shackle
- Choose the right type of unit for what you're storing — antique furniture needs a climate-controlled indoor unit, not an outdoor metal container
- Stick to the facility's list of prohibited goods — no paint tins, gas cylinders, or fireworks. Items like these increase the risk of fire and could invalidate your insurance
The financial security that insurance provides
Even a well-run facility can experience a fire, flood, or break-in. Security measures reduce risk — they don't eliminate it. Insurance is what protects you financially when something does go wrong.
Your storage insurance should cover the full replacement value of everything in the unit — not what you paid originally, but what it would cost to replace each item today. Keep an inventory of what you've stored, with photos where possible, so you have everything you need if you ever have to make a claim.
