David House (right) acquired Allens of Mayfair in May 2006, in partnership with Justin Preston. They bought the butchers from the administrators 18 months ago and have since built it into a thriving retail and catering butcher. House and Preston also jointly own Rare Butchers, a successful Kent-based catering butchers they set up in 2000. Both men began their careers when they were teenagers, working as trainee butchers for GG Baxters at Smithfield Market.
