Expert Witnesses for Criminal Defence Proceedings

Criminal defence proceedings — from Magistrates Court summary trials to Crown Court jury trials for the most serious offences — frequently require independent expert evidence on medical, psychological, forensic, and scientific questions. The quality and credibility of that expert evidence can be decisive in determining the outcome of a case.

Expert Witness UK provides criminal defence solicitors and barristers with access to a nationwide panel of accredited medical and forensic expert witnesses. Every expert on the panel holds the relevant professional registration (GMC, HCPC, or equivalent), operates within the applicable regulatory framework, and has demonstrable Crown Court experience. All reports comply with the Criminal Procedure Rules 2020, Part 19.

We accept instructions under Criminal Legal Aid and work within LAA rates. Our case managers have extensive experience with the Legal Aid Agency\'s prior authority process and can advise on the appropriate fee structure for the specific type of report required.
