The man, identified as Rightous Garnett, was sentenced after pleading guilty to the 2014 burglary of the billionaire’s house.
Police reportedly found over £160,000 worth of jewelry in Mr Garnett’s house during a raid last year.
Garnett is a personal trainer.
This is not his first offense; in 1988 he tricked his way into the home of a lady and attacked her butler before fleeing empty handed.
In 2002 he was jailed for a series of burglaries and he again served 7 months for a raid on a house in 2012.
