The BBC moved 850 staff from London to Salford in 2011 at a cost of £11 million to cover relocation expenses. Staff were given financial incentives worth 10% of their salary to encourage relocation. While the BBC claimed benefits like improved productions and reputation from the move, it was criticized for excessive relocation payments like £150,000 to buy a £1 million home. The National Audit Office also said the BBC's recording of exceptions for higher payments was inadequate. The BBC spent £2 million on flights between Manchester and London in the first two years after the move.
