Katie Sage

Call 2014

“A real star in the making. Ferociously bright and hardworking, and with incredible powers of recall combined with an intuition for wider case strategy."
(Legal 500, 2023)

Katie specialises in criminal regulatory law, inquests and inquiries.

She is regularly instructed as junior counsel in complex and high-profile public inquiries and inquests. Katie represents the Royal Borough of Kensington and Chelsea in the Grenfell Tower Inquiry. She is also instructed in the COVID-19 Inquiry and in the inquest arising from the Forbury Gardens Terror Attack. Alongside these cases, she is often instructed as sole counsel in shorter inquests covering a wide range of industries including care homes, manufacturing, waste, retail, construction, maintenance and social housing.

In terms of criminal regulatory work, she has recently represented Serco Ltd in a 17-day Newton Hearing following its plea to s. 2 Health and Safety at Work etc. Act 1974 (led by James-Maxwell Scott KC) and was counsel for the company in the corporate manslaughter prosecution of Greenfeeds Ltd (led by Mark Balysz KC). She regularly appears in the Magistrates’ Court, defending criminal regulatory prosecutions on behalf of both companies and individuals and in the Crown Court for companies. She has also prosecuted for Thames Water.

She also maintains a practice in professional negligence, product liability and property damage.

Prior to joining Chambers, Katie was employed on the Civil Service Fast Stream where she gained valuable public and commercial sector experience through her roles in communication, legislative reform and international trade.

Outside of work, Katie played for Great Britain in the 2015 Tag Rugby World Cup and is back training with Great Britain as part of the 2023 World Cup campaign.
