Large Storage Units in London

Our large storage units across London offer flexible space for businesses and individuals who need room to grow. Whether you are storing retail stock, ecommerce inventory, tools, equipment, materials or business archives, our units provide an alternative to overcrowded offices or expensive warehouse space.

Units range from 100 to 500 sq ft, giving you the flexibility to choose a size that suits your current needs. As your requirements change, you can easily move between unit sizes. Our largest storage unit, at 500 sq ft, offers capacity comparable to three double garages, making it ideal for larger operations or high-volume storage.

With complimentary 24-hour access included as standard, you can get to your unit whenever it suits you. You will receive a unique PIN to enter the facility and secure your unit with your own padlock, so only authorised individuals have access to your space.

All our large storage units are highly secure, with perimeter fencing, 24-hour CCTV monitoring, and individually alarmed rooms. Our facilities are bright, well maintained, and designed to give you confidence every time you visit.

Moving heavy or bulky items into storage does not need to be complicated. At Attic Self Storage, our experienced team can assist with forklift access, helping to position and store your goods and pallets safely and efficiently. 

For businesses managing stock day to day, our parcel receiving and delivery service helps keep your operations moving, while mailbox rental provides a reliable business address. Find out more about our available services when you rent one of our large self storage units today.

Space is often limited in London. Lofts and basements are frequently converted into living areas, while outdoor space is rarely large or secure enough for long-term storage. Whether you are moving, renovating, decluttering or simply short on space, our large self storage units offer a flexible and practical solution.
