IRWIN MITCHELL LLP

What IRWIN MITCHELL LLP does

Irwin Mitchell LLP is a UK-based full-service law firm structured as a Limited Liability Partnership, operating from 21 offices across England, Scotland and Wales with its UK headquarters in London and a separate regulated Scottish practice, Irwin Mitchell Scotland LLP, under the Law Society of Scotland. The firm has been operating for approximately 113 years and reports having represented over one million clients. It is regulated by the Solicitors Regulation Authority (SRA) in England and Wales. Day-to-day work is delivered by qualified solicitors through in-person consultations, telephone contact, and website-based enquiry forms with callback options, operating Monday–Friday 8am–6pm.

The practice is organised into three main areas. Medical Negligence & Personal Injury is the flagship, ranked #1 in the UK by Legal 500 2026 and covering birth injuries, cerebral palsy, cancer misdiagnosis, surgery errors, road traffic accidents, serious injury, asbestos, military injuries, and group claims, with No Win No Fee arrangements offered for qualifying matters. Personal Services includes conveyancing, family law, employment, immigration, insolvency, probate, tax, wills/trusts/estates, and court of protection. Business Services covers banking and finance, corporate/M&A, commercial disputes, employment, ESG, intellectual property, licensing, real estate, regulatory and compliance, restructuring and insolvency, tax, crime and investigations, and sector-specific advice across agriculture, betting and gaming, education, financial services, landed estates, manufacturing, natural capital, retail and hospitality, sport, and technology.

Revenue is generated through traditional fee-for-service billing — hourly, fixed-fee, and contingency (No Win No Fee / Conditional Fee Arrangements) — with pricing not publicly disclosed and bespoke quotes issued per matter. The go-to-market is direct and sales-led, anchored on the 21-office physical network, brand reputation from 113 years of operation, and marketing channels including the corporate website, social media (Facebook, Instagram, LinkedIn, X, YouTube), PR/earned media, Trustpilot reviews, and themed campaigns such as 'What If.' The source data records no proprietary technology platform, no API/SDK offerings, no AI/ML capabilities, and no disclosed revenue or headcount beyond a firmographic entry of 82 employees (which appears inconsistent with the rest of the operational footprint).
