What our customers say

‘Thornbury Self Storage were both helpful and flexible during my parents recent house move.
They saved us time and inconvenience and were ideal for my elderly parents as it is all on ground level. They could even buy their bubble wrap and tape onsite at competitive prices! We would definitely recommend them!’
Mrs Boxall

Thank you for your friendly efficient service. The whole site is immaculate with trolleys to move items. The really helpful staff turned what could have been a very stressful situation in to almost a pleasure.
Your service has worked very well for us and it is really convenient and easy to use when moving house!


'I would like to thank Thornbury Self Storage for providing safe and dry storage for a large quantity of items, including clothing and paperwork, which ensured that the condition of this property was as good when we collected it as when we deposited it more than three years earlier. I would highly recommend them.'

Mr Jordan

I have been using Thornbury Self Storage since 2006 and I can recommend this service to anyone who needs storage! The facility is secure and immaculate and there are even trolleys and sack-trucks to assist with heavy items. I am always impressed by the excellent staff who are always friendly and helpful each time I visit. Highly recommended!
