This place is a big con - all their warehouses are set up near the city centres to purposely get students (or in Birmingham near LGBT community) basically vulnerable people. When you sign up they ask for two forms of ID so basically they have your Passport number and driving license number as well and if you don't pay they will chase you.
Also, their head offices are in Park Lane London - which is a posh area of London so your hard earned money goes to paying the rent there.
They give you lots of fancy paperwork and don't tell you that their insurance is a rip off. You can create your own online which is way cheaper. I got one for £20.00 for three months. Bring your own padlock as otherwise they will sell you one for £13.00 (another rip off). Staff are untrustworthy and the warehouse they have is inadequate. Try Safestore its a short drive away but better service and better rates read more
