Choosing between container storage and indoor self storage? The main differences are the space you rent, how you load it, the storage environment and the total cost.
Container storage is a form of self storage. Here, we compare outdoor, drive-up steel containers with storage rooms inside a building, so you can decide which suits your belongings and budget.
Quick answer
Container storage can offer good value for bulky loads such as furniture, tools and business stock, particularly when you want to drive directly to your unit.
Indoor self storage may be a better fit for a small load or belongings that need a specific controlled environment. Check the individual facility: being indoors does not automatically mean a unit is heated or climate-controlled.
At Accrington Container Storage, a full-size 20ft container costs £150 per month including VAT, with 24/7 customer access, a supplied padlock and monitored CCTV.
What Is the Difference Between Container Storage and Indoor Self Storage?
Container storage means renting a steel container at a storage site, usually with outdoor access directly to its doors. Indoor self storage means renting a room or unit inside a building, with access arrangements that vary between facilities.
Both give you space to store belongings. Neither format automatically guarantees better security, lower prices or protection from damp.
| Feature | Container storage | Indoor self storage |
|---|---|---|
| Space | Often full-size containers. ACS offers 20ft units. | Often a range of room sizes, including smaller units. |
| Total price | Can be good value for larger loads. ACS costs £150/month including VAT. | Depends on size, provider, rental period and extras. A small room may cost less overall. |
| Loading | Usually direct vehicle access to the container. | Check the route from the loading area, including corridors or lifts. |
| Access hours | Provider-dependent. ACS customers have 24/7 access. | Provider-dependent; check customer access separately from office hours. |
| Environment | Ask about condition, ventilation and condensation treatment. | Ask whether the room is unheated, heated or climate-controlled. |
| Security | Check gates, fencing, monitoring, locks and access controls. | Check building access, monitoring, unit locks and alarms. |
Is Container Storage Cheaper Than Indoor Self Storage?
It can be, particularly when you need substantial space, but compare the full cost for the amount you actually need. A smaller indoor unit may cost less than a full container if you only have a few boxes.
At ACS, a 20ft container costs £150 per calendar month including VAT. At that rate, rent would total:
- One month: £150
- Three months: £450
- Six months: £900
These figures cover unit rental. Allow separately for transport and any insurance you arrange for your belongings.
How to Compare Storage Quotes Fairly
Ask each provider for the total payable over your expected rental period, including:
- VAT: is it included in the advertised price?
- Billing period: is the price weekly, every four weeks or per calendar month? Four-week billing means 13 billing periods a year.
- Promotional rates: what will you pay after an introductory offer ends?
- Extras: are locks, access, administration or insurance charged separately?
- Terms: what are the minimum stay and notice requirements?
- Usable space: will your furniture fit, and can you still reach items you need?
ACS includes a CISA padlock, steel lockbox protection and 24/7 customer access within the monthly rent. For more detail, read our Accrington storage cost guide.
Loading and Access: Which Is More Convenient?
Drive-up container storage lets you bring your vehicle directly to the unit. This is useful for sofas, appliances, heavy toolboxes and repeated stock collections because it reduces the distance you carry items.
Indoor storage can provide a more sheltered route, but check the actual loading arrangements. Your room may be near the entrance or require a longer trip through corridors and lifts.
Frequent visits do not automatically favour either format. What matters is the route to your unit, the items you collect and the hours when you need access.
ACS customers can access their containers 24/7. Office opening hours are separate, so arrange visits requiring staff assistance in advance.
Are Storage Containers as Secure as Indoor Units?
Both can provide secure storage. Assess the individual facility rather than judging security from the building type alone.
At ACS, protection includes:
- Perimeter fencing and electric gated entry
- 24/7 monitored CCTV
- A supplied CISA padlock protected by a steel lockbox
When comparing providers, ask how entry is controlled, whether CCTV is monitored or only recorded, and what protection is fitted to your unit.
Damp, Condensation and Item Suitability
Indoor storage is not necessarily climate-controlled, and a steel container is not automatically protected against condensation. Ask what measures the facility uses and whether they suit your belongings.
ACS containers are anti-condensation treated to help reduce moisture build-up. Treatment does not remove the need to pack correctly: furniture, tools, clothing and covers should be clean and dry before storage.
For delicate or particularly temperature-sensitive belongings, check the recommended storage conditions and look for a facility that can meet them.
Our guide to container damp and condensation explains the practical precautions in more detail.
Should You Choose a Container or an Indoor Unit?
A container may suit you if:
- You have bulky furniture, tools, equipment or business stock.
- You want to load directly from your vehicle.
- You need enough space to organise belongings and retrieve them later.
- The facility’s environment and access arrangements meet your needs.
An indoor unit may suit you if:
- You only need a small amount of space.
- You prefer sheltered access inside a building.
- You need specific temperature or humidity control that the provider confirms it offers.
ACS offers full-size 20ft containers, advertised at approximately 160 sq ft. Capacity depends on the size of your belongings, packing and the access space you leave. Read whether a full 20ft container is right for you before booking.

Container storage is a type of self storage. The comparison is between a steel container with outdoor access and a storage room inside a building.

Can I store furniture in a container?
Yes, suitable containers can be used for furniture storage. Check the container’s condition and condensation protection, and make sure furniture is clean, dry and packed appropriately.
Are indoor self storage units climate-controlled?
Not necessarily. Indoor units may be unheated, heated or climate-controlled. Ask the provider what temperature and humidity controls are available.

Either can work. Choose according to your load, total cost, access needs and rental terms. A container can suit a bulky house move, while a smaller indoor room may suit a few boxes.
Does storage security include insurance for my belongings?
Security measures and insurance are separate. Check whether your belongings are covered while stored away from home or your business, and confirm any conditions with your insurer.
