The industry has been so popular with investors, it’s even spawned several podcasts advising would-be moguls on how to get into the business.

Entrepreneur Dean Booty from Beverley in East Yorkshire is one of them.

“I had a restaurant business, and it failed, and it was a miserable time for me and my wife. It was in the centre of a town where I lived in. It really hurt my ego.”

Mr Booty says this was the inspiration to share his success in self-storage with others.

His podcast Hacking Self Storage gets around 15,000 listens each month, he reveals, adding “I had no idea there was that many people interested in self-storage, which is incredible.”

Mr Booty’s storage operation comprises just under 100,000 square foot in five locations across England, Scotland and Wales.

The 42-year-old father says he’d like to retire by age 50.

“There’s massive amounts of money coming into the industry, which only means it’s going to become more and more competitive, but at the minute, the demand is growing faster than the supply in the UK, which is incredibly exciting,” he adds.
