The number of mid-sized chambers is falling dramatically as they are squeezed out by their larger, bigger spending rivals, BDO Stoy Hayward’s benchmark annual survey of the Bar has revealed.

The report shows that during the past two years, the number of chambers in the 10-30 tenant bracket has slumped from 175 to 130, while the head count of sets in the 30-50 bracket has jumped from 110 to 150.
