The team at reception always go out & beyond, doing their very best within their means to accommodate any given situation, and this conclusion has been reached after maintaining a unit there for an approximate 5 years ! ! ! It almost feels like "home" by now. And that's much appreciated indeed...🙏

Big Yellow has been an absolute dream to store with, but what truly made this experience so special is Csaba! He brings such a rare blend of professionalism, kindness, and genuine care; the kind that stays with you. He is, quite simply, a gift to Big Yellow, and someone who elevates the entire experience just by being who he is. So grateful, thank you Csaba! 💛💛💛
Frequently asked questions
To start renting your storage room, you’ll need to visit the store to sign your customer licence and pay for your initial 4-week period, deposit, and contents protection.
Contents protection is required before you can begin storing. You can either use our Enhanced Liability Service or provide your own insurance policy, but it must specifically cover self storage and clearly list our store address. A copy of the policy will need to be provided before move-in.
Don’t forget you'll need a padlock to secure your room - we sell combination locks at the store if you need to buy one.
If you need help getting your items to us, we’re happy to recommend trusted local removal companies. Alternatively, you can bring your belongings by car and use the trolleys available onsite to move them easily into your storage room.
We have over 25 years of experience in offering safe and secure storage. This includes individually alarmed rooms with unique PIN code entry, 24 hour monitored CCTV, electronic security gates and manned stores - we're onsite every day of the week.
Our reception opening hours are:
Monday - Friday 8:30am and 5:30pm
Saturday 9am and 5:30pm
Sunday 10am and 4pm
During these hours you can come and go to your storage room as many times as you need. If you need access beyond these hours come and have a chat with us and we'll see what we can arrange. We may be able to organise extended hours access for an additional fee. However this is subject to store discretion.
Our extended access hours are:
Monday - Sunday 5am and 11pm
Yes, absolutely. If your needs change or you’ve booked the wrong room size, we’re happy to help you switch to a larger or smaller unit. Room changes are always subject to availability, but we’ll gladly show you what’s available and find the best fit for you.
Most of our rooms only require 14 day notice to move out. Our larger room sizes of 1,000 sq ft and above and our rentable car parking spaces do require 28 days notice please.
Any days paid for but unused are then refunded back to you when you move out.
Box shop
Pack smarter, move easier.
Everything you need for moving day or self storage: sturdy boxes, bubble wrap, packing tape, dust sheets, mattress bags and more. Whatever needs to be moved, stored or protected, you'll find it all in our Box Shop.
