How Many Units Does a Self Storage Facility Typically Have?

Understanding the Average Size and Unit Variations of UK Storage Facilities

Not all storage sites are built the same. Some are compact and local, like a corner shop, while others are massive, purpose-built spaces, more like a supermarket for storage.

Smaller facilities (50 – 200 units) – These are often found in rural areas or specialised markets (like student storage). Some are converted warehouses or local removal businesses that have added storage as an extra service.

Larger facilities (200 – 1,000+ units) – Found in big cities or near major transport hubs, these facilities maximise every inch of space, often with multi-storey storage and a mix of unit sizes.

Unit size matters – A facility that offers smaller units (lockers, document storage) will naturally have a higher unit count than one specialising in large-scale storage for furniture, vehicles, or business stock.

At blue self storage, our units range from 48sqft to 320sqft, catering to everything from personal storage to business stock and vehicle/caravan storage – and you can book yours online in minutes!

What Factors Influence the Number of Storage Units in a Facility?

Several key factors shape how many self storage units a facility has:

✔️ Location – In Cardiff city centre, space is at a premium, so sites tend to be multi-storey to maximise storage capacity. In rural areas, storage facilities can spread out horizontally, offering larger, ground-level units.

✔️ Target Market – If a site is near a university, it might focus on small, short-term units for students. A facility catering to businesses will likely have larger units for stock and equipment storage.

✔️ Local Demand – In areas with high demand for storage, operators will pack in as many units as possible to meet customer needs.

✔️ Competition – If there are other storage providers nearby, a new facility might focus on a specialist niche, such as climate-controlled storage or vehicle storage.

✔️ Business Strategy – Some facilities prioritise smaller, high-occupancy units, while others focus on fewer but larger units with higher rental fees.

How Does Unit Mix and Occupancy Rates Affect Total Unit Numbers?

A smart unit mix is essential for maximising occupancy rates and profitability.

Storage providers analyse market trends to offer the right unit sizes – too many large units in an area where most customers only need 50sqft could lead to empty space and lost revenue.

Occupancy rates – the percentage of units rented at any time – are a key factor in storage facility success. The total number of units available directly affects how much revenue a facility can generate.

At blue self storage, we focus on a balanced mix of unit sizes, ensuring both households and businesses have the perfect space for their needs. And the best part? You can check availability and book your unit instantly online.

How Do Market Demand and Competition Shape Storage Facility Growth in the UK?

The self storage industry is growing fast – but not all areas see the same demand.

📍 Growing cities and high-density housing – As living spaces shrink, more people need off-site storage. In urban areas, multi-storey storage facilities are common to maximise unit numbers.

📍 Business expansion – Companies looking for cost-effective stock storage drive demand for larger units.

📍 Competition between providers – Storage operators adjust pricing, unit sizes, and extra services to stay competitive, often increasing the variety of unit options available.

With so many options available, how do you pick the right storage unit?

Consider the amount of space you need – Do you just need a small 48sqft unit for a few boxes, or are you looking for a spacious 320sqft unit to store furniture and business inventory?

Book in advance – Demand increases during peak seasons, especially summer moving periods and university term dates.

The Role of Technology in Optimising Storage Facility Management

Modern storage facilities don’t just rely on lock-and-key access anymore.

Management software – Tracks unit availability, occupancy rates, and customer bookings in real time.

Data-driven decision-making – Storage companies analyse customer trends to predict demand and adjust unit mix accordingly.

Contactless access & security – Features like QR code entry, 24/7 CCTV, and smart locks are becoming more common, making storage even more convenient and secure.

At blue self storage, we invest in the latest security and access technologies, ensuring your belongings are safe and accessible whenever you need them.

Future Trends in UK Self Storage

As urban spaces shrink and demand grows, the self storage industry is evolving fast.

🔹 More multi-storey storage facilities – With land prices rising, facilities are going up instead of out.
🔹 More flexible rental terms – Short-term, pay-as-you-go storage is becoming increasingly popular.
🔹 Greater variety of unit sizes – Customers want custom storage solutions that match their specific needs.
🔹 Sustainable storage initiatives – Facilities are introducing green roofs, solar power, and energy-efficient systems.
