- Personal Storage
- Business Storage
10sq ft
This is our smallest unit, which is referred to as a locker. Lockers are ideal for storing a few boxes, suitcases or bags and are very popular with students for storage outside of term time.
Examples of personal storage uses:
- Selection of seasonal sports equipment e.g. golf clubs.
- A few suitcases for students over summer, or storage in preparation for planning a gap year travelling
- Book, magazine or newspaper collections

20sq ft
One of our smaller units, this is suitable for small pieces of furniture and other small items. It is useful for students or anyone looking to store excess items from their attic or shed. It holds around the same amount as one small van, which could also be the ideal way to transport your items.
Examples of personal storage uses:
- Small furniture or appliances e.g. a vertical shelf or washing machine
- Garden tools and other items that won’t fit in your shed
- Small hobby items that you don’t want stored in your home

25sq ft
This is one of our more popular smaller units, and is suitable for small items of furniture and boxes. Customers moving items into this size room might be using an estate car or small van to transport their goods. The size of the room corresponds roughly to the size of a small garden shed, and is ideal for those items in your home that are used seasonally.
Examples of personal storage uses:
- Hobby equipment that you don’t want cluttering the house
- Seasonal items e.g. decorations, camping equipment, summer tools
- Medium size furniture items or appliances e.g. fridge, washer-dryer, dresser

40sq ft
This room is suitable for small consignments of furniture and boxes, and is likely to accommodate goods equivalent to those that could fit inside a typical transit van, a large garden size shed or a small one-person flat.
Examples of personal storage uses:
- Kitchen appliances
- Freeing space up in a garage or shed by storing seasonal items, motorbikes, or larger gardening tools
- A small one-person flat’s worth of furniture, along with plenty of space for boxes

50sq ft
This is one of our most popular sizes, and is suitable for an apartment’s worth of items and furniture. Its capacity is similar to that of a mid-sized van.
Examples of personal storage uses:
- All items from a standard-size studio flat
- Large bulky furniture from a small flat, including large kitchen appliances
- Perfect for renovation or moving day for a small flat

80sq ft
This size unit is great for anyone who is clearing out a large apartment or several rooms from a small home. Ideal for boxes and furniture, as well as items from the garage or attic, this unit has a capacity similar to that of a normal-sized van.
Examples of personal storage include:
- Bedroom furniture, including beds and sofas
- Large appliances and bikes

100sq ft
Often used as a room to store the contents of a 2-bedroom flat or small house. This size of room can also offer the convenience of circulation space, for example: if you need a room that gives space to store away or withdraw items frequently, then this is a good choice to give you room to manoeuvre.
Examples of personal storage uses:
- Contents of 2-bedroom home, including large pieces of furniture
- 3-piece suites, or large, awkwardly-shaped furniture
- Furniture for a new nursery

150sq ft
This size is suitable for storage of consignments moved to store by truck and will normally accommodate the contents of a typical two or three-bedroomed house. Our 150 sq ft units will often be found at ground floor level within our stores for additional ease of access.
Examples of personal storage uses:
- Contents of entire three-bedroom home while moving or renovating
- Large, bulky furniture such as sofas, dining tables and beds
