Chambers are offices from which self-employed barristers practise, often sharing administrative teams and other office costs. Newly called barristers wanting to pursue self-employed practice seek "pupillage" within chambers, during which time they are supervised by a more senior barrister and may start to take on cases.

The below chart represents a snapshot of the number of chambers with more than one practising barrister (including where barristers are practising from the chambers as a secondary address) as of 1 December in each year.
