Serjeants' Inn Chambers

What Serjeants' Inn Chambers does

Serjeants' Inn Chambers is a London-based barristers' chambers (formerly '3 Serjeants' Inn') operating from 85 Fleet Street, specialising in medical law, police law, professional discipline and regulation, Court of Protection, inquests and public inquiries, and related public law. The chambers fields 100+ barristers, including multiple Band 1-ranked silks (King's Counsel), and is jointly led by Michael Horne KC (since 2019) and Claire Watson KC (since 2025). Practice areas span clinical negligence, healthcare regulatory advice, Court of Protection, police misconduct, education, employment, business crime, mediation, and product liability, with a published treatise (Medical Treatment: Decisions and the Law, 4th edition) anchoring its thought leadership in medical treatment law.

The chambers generates revenue through professional services fees paid by instructing solicitors, public bodies (NHS Trusts, police forces, local authorities, the Official Solicitor), regulators (GMC, GDC, NMC, GOC), and individuals via the Direct Access (Public Access) Scheme. Pricing is quote-based, varying by seniority of counsel and case complexity, and barristers are self-employed members who contribute a percentage of earnings to chambers ('cribbing'). Distribution is primarily relationship-driven via instructing solicitors and a clerking team that allocates matters, supplemented by legal directory rankings (Chambers & Partners, The Legal 500) and content marketing through specialist blogs and publications.

Recent strategic activity centres on the integration of AI tools into legal practice — including a proprietary AI Damages Calculator App and ChatGPT-assisted case analysis — alongside an emerging advisory practice in AI liability in healthcare. The chambers is regulated by the Bar Standards Board and operates exclusively within England and Wales, with selective international engagements such as advisory work for the Singapore Medical Council.
