Essex-based entrepreneur Mr Best, 43, paid an undisclosed fee for the six parks.
He has already employed a new sales area manager and there could be more job opportunities for further staff in the future.
The former amateur boxer’s business is reputedly worth over £100 million. He started his first aged 14, buying and selling vans.
Later he opened a series of mobile phone shops in London before purchasing a small caravan park in Essex, gradually building up the business by acquiring sites across the UK.
His teenage son, also named Alfie, starred in Channel 4’s My Big Fat Gypsy Fortune documentary two years ago.
The newly acquired parks are located in Sticker, Otterham, Dunmere, Bodmin, Helston, and Trelowth.
