What is self storage?
Self storage means renting purpose-built indoor storage units within secure facilities, usually in convenient city locations. Units come in a range of sizes, from lockers to rooms, and contracts are flexible so you only rent the space you need.
At HOLD, you can request 24-hour PIN access and choose climate-secure options for items that need extra care.

What is container storage?
Container storage uses steel shipping containers. Storage containers are standardised and portable, commonly 10, 20 or 40 foot, placed in outdoor yards or delivered for drive up use.
Each container is weather resistant and secure, lockable, secure and good for bulky items or long term store. You can store boxes, store archives and store seasonal kit.
Pros
- Large single volume with simple pricing. A strong budget option for long stays.
- Ground level entry that works for pallets, kit, bikes and heavy equipment.
- Additionally helpful for business storage, temporary site materials or vehicle storage.
Cons
- Susceptible to condensation without ventilated linings
- Out-of-town sites can be less convenient to visit
The big differences that matter
Access and convenience
If you plan weekly visits, indoor self storage wins for lifts, covered bays and long opening hours.
Container storage often works for a single move in then leave approach, though some operators place a container at your house, in garages or at your business for short periods.
Pick the model that will suit your routine and suit your timing and storage needs today.
Environment and item care
Indoor rooms reduce temperature swings and humidity. That helps with wood, textiles, artwork and electronics.
Outdoor container storage is robust, but moisture can form inside unless the box is dry and well vented.
For heirlooms or delicate possessions, indoor secure storage is usually safer and provides control.
Security approach
Self storage adds controlled entry, monitored corridors and staff presence on top of locked doors. This creates clear layers between street and unit.
Yard facilities rely on fencing plus the container lockbox and padlock. Choose the level that fits your items and gives peace of mind.
Sizes, flexibility and term
Self storage gives a wide range of unit sizes with short terms, so you can change as projects grow or as plans change.
Container storage fixes you to one large container, which is ideal when you know the volume and duration.
Loading style and safety
Self storage provides trolleys, lifts and covered bays that keep manual handling safer and more accessible.
Containers are ground level and work for palletised goods, kit and heavy gear, but delivery and siting on your site need safe crane entry and space to position and fill the box.
Cost and budget
If lowest price per cubic metre matters and visits are rare, container storage can be cost effective.
If frequent trips, central location, temperature regulated rooms and on site service matter, indoor storage offers better value.
Location and service
Self storage is typically in urban locations with staffed facilities and modern storage facilities, clear process and documented processes and a friendly team.
Secure container storage yards are often on the edge of town with fewer extras. Decide which service style works for your customers, colleagues or family customers. Customers value clear pricing and simple terms.
Real world examples
Home renovation with regular visits
You need short trips for seasonal clothes and important documents, plus indoor conditions for antiques. A temperature-regulated self-storage unit near your location gives quick, accessible visits and tidy aisles for customers and trades. Result is practical control and peace of mind.
Seasonal business kit with rare access
Landscaping tools and machinery can sit in a 20 foot container through winter. Drive up loading is simple, and overall price is attractive when you do not visit weekly. For business, this is a safe, secure way to store equipment between contracts in the UK.

Prices vary by location and term. Container storage is often cheaper per cubic metre, while self storage gives more service and visits. Always compare total price including insurance, any sale of packing materials and any supply of locks or padlocks.

What size storage container do I need?
A 20 foot container suits many house moves and company stock. Check container sizes in feet and cubic metres, and review unit sizes if you prefer indoor rooms.
Can I use vehicle storage at a container yard?
Many yards offer vehicle storage for cars, vans or bikes. Check opening hours rules, proof of ownership and whether the space is covered.
How do I prevent condensation in a container?
Start with a dry box, add a well vented lining or desiccants, and avoid sealing wet items inside. Open the doors on dry days to refresh air.
Do self-storage facilities have 24-hour entry?
Only a few self storage facilities (like HOLD) offer 24 hour entry with PIN entry to storage units. Confirm what your chosen location provides and whether the service is included in the price.
What does indoor self storage mean?
It means indoor storage units and corridors of storage units inside a managed building with staffed reception, lifts and trolleys. It differs from outdoor containers in entry, environment and service.
Can I store tools and materials in a container?
Yes. Tool storage and materials storage are common use cases. Keep items dry, use pallets, and leave a walkway so you can reach what you store.
