Richard Sage

Call 2006

“Very hardworking and will dedicate himself to a case. He is always available to provide a guiding hand and his advice is invaluable.”
(Legal 500, 2021)

Product Liability

Richard has a busy and successful practice in the field of product liability law, complemented by his extensive knowledge of the law relating to construction, insurance and professional negligence. He was led by Alexander Antelme QC, alongside David Myhill, in the ground-breaking metal-on-metal hips litigation (Gee v DePuy International [2018] EWHC 1208), and continues to act in relation to similar disputes in other jurisdictions. He is regularly instructed on cases involving complex engineering evidence, reflecting his background in construction claims.

Richard’s product liability practice means is complemented by his considerable experience in property damage claims. He was junior counsel in one of the leading decisions of the Court of Appeal on proving causation in fire claims (Milton Keynes BC v Nulty [2012] EWCA Civ 15) ,and is junior counsel to one of the defendants in the Clandon Park litigation, where a nationally important stately home was destroyed in a fire. Richard has acted for insurers of multiple defendants facing hundreds of claims for installing allegedly defective cavity wall insulation in homes across the UK, with a substantial combined value.

Richard’s practice means he is very familiar with coverage disputes relating to product liability claims, and therefore he regularly advises on the scope of indemnity provisions, exclusions, warranties, and on issues such as misrepresentation and non-disclosure.

Richard is recommended in Chambers and Partners and the Legal 500 for his product liability work.
