What Simons Muirhead Burton does

Simons Muirhead Burton (SMB) is a London-based, partner-led full-service law firm founded in 1971, operating as a private partnership with 101–250 employees and headquartered in London, United Kingdom. The firm serves businesses, organisations, and individuals across eleven specialist practice areas: Corporate, Commercial & Finance; Crime & Regulatory; Dispute Resolution; Employment & Immigration; Family; Media; Media & Communications Disputes; Music; Real Estate; Sport; and Tech, IP & Digital Rights. Its value proposition centres on a partner-led approach combining specialist expertise with personal service, drawing on heritage from its civil-liberties and criminal-law roots in Soho. SMB is recognised by Chambers and Partners 2026, UK Top Tier Firms 2026, and Spear's Legal Indices, with Partner Phil Smith repeatedly ranked as a Top Recommended Criminal Lawyer.

The firm operates a professional services revenue model, earning fees from legal advisory and representation work billed under individual engagement terms; pricing is opaque and clients are directed to price transparency information. Go-to-market is sales-led and relationship-driven: clients are acquired through direct partner engagement, professional referrals, the firm's website and insights content, and directory recognition. Distribution is domestic (UK) with international reach via the LAWorld legal network for cross-border referrals. Beyond its core practice, SMB founded and continues to support The Death Penalty Project (DPP), a non-profit charity providing free legal representation to individuals facing the death penalty, now operating across 30 countries.

The firm's technology posture is described as a standard law-firm stack with no proprietary platforms, integrations, or APIs; the only certified technology credential is Cyber Essentials Plus for cybersecurity. Ownership is independent and partnership-controlled, with no parent company, private equity backing, or external institutional investment disclosed. Recent strategic activity includes a partner promotion (Gordon Clough, May 2026), ongoing LAWorld AGM participation, and active thought-leadership publishing on regulatory topics.
