Kelly is regularly instructed in complex and often high-profile cases by both prosecuting authorities and defence solicitors.  He has particular expertise in cases involving sensitive material and investigative procedures, especially where covert and technical surveillance have been deployed.  He also has experience of cases with cross-jurisdictional issues such as war crimes, international cybercrime, and terrorist offences committed abroad.

Kelly is a grade 4 prosecutor and a member of both the CPS Counter-Terrorism and Serious Crime Group panels.  He is experienced in working with a range of investigative agencies and government departments, and also in managing and presenting matters involving very large volumes of material.  This sees him often brought into complex and sensitive cases at an early stage to advise pre-charge on evidence and sensitive disclosure matters.  His work in counter-terrorism has seen him prosecute at trial a large number of matters across a range of political  and ideological extremes as both junior alone and as a led junior.

Kelly is appointed to the Serious Fraud Office panel B of junior counsel and is also an approved pupil supervisor.

Kelly advises and represents private individuals facing criminal charges and is often sought out to assist members of the armed forces and those in sensitive intelligence roles whether appearing in the Crown Court or at Court Martial.
