What Old Square Chambers does
Old Square Chambers is a UK barristers' chambers headquartered at 10-11 Bedford Row in London, with a regional office in Bristol, providing specialist advocacy and advisory services across more than 17 practice areas including Employment & Discrimination, Personal Injury, Clinical Negligence, Professional Discipline & Regulation, Administrative & Public Law, Civil Liberties & Human Rights, Commercial Law, Costs, Data Protection, and Health, Safety & Environmental Law. The chambers is composed of self-employed barristers — including 19 King's Counsel and a broader roster of 100+ counsel across seniority levels — supplemented by an in-house clerking and business support team of approximately 14 staff led by a Chambers Director.
The chambers operates a traditional professional services model in which barristers are instructed primarily by solicitors and law firms, with additional direct corporate, NHS Trust, and public sector instructions, plus a Public Access scheme allowing members of the public to instruct counsel directly. An ADR & Mediation offering extends the service line into alternative dispute resolution. Distribution is intermediated by a Senior Clerk-led clerking team that proactively matches instructing solicitors and direct clients with appropriate counsel based on expertise, seniority, and availability. No proprietary technology platform underpins the offering; services are delivered through in-person advocacy in tribunals, courts, and inquiries, written advisory opinions, and mediation.
The chambers was recognised as Chambers of the Year at The Lawyer Awards 2026, is consistently top-tier ranked in Legal 500 and Chambers & Partners, and is regulated by the Bar Standards Board. Revenue is not publicly disclosed, and the entity operates independently with no parent company, private equity ownership, or external institutional investment indicated. Marketing reach is driven by directory rankings, a seminar and CPD programme across London, Bristol and Manchester, case-analysis publishing, and direct engagement by the clerking team.
