The Institute of Legal Executives (ILEX) is a professional body with over 22,000 members. ILEX is recognised as the third branch of the legal profession, alongside solicitors and barristers. Legal Executives have their own recognised status and role within the legal profession, working in law firms, government departments and private companies. Their day to day work is similar to that of a solicitor, although the training and qualifications are different.

The Criminal Law Solicitors' Association is the only national association entirely committed to professionals working in the field of criminal law. The CLSA represents criminal practitioners throughout England and Wales and membership of the Association is open to any solicitor - prosecution or defence - and to court clerks, qualified or trainee - involved with, or interested in, the practice of criminal law.

With origins dating back to 1913, the Association of British Investigators is now recognised as the premier professional body for private investigators working in the United Kingdom. Throughout its long history, the Association has worked hard to improve the standing and reputation of the investigative professional.

The Investigators' Sector was formed to co-ordinate discussion and debate on the Private Security Industry Act, and to represent the interests of all practicing investigators in England and Wales on licensing issues following the enactment of the Act.

JSIC helps coordinate representations from the industry in discussions with Government and the police on security industry matters, and in turn helps in the process of distributing information from these discussions and other sources back to the industry.
