What MSL UK does
MSL UK is a London-based public relations and communications consultancy and the UK operating entity of Publicis Groupe's global MSL PR network. The agency serves enterprise clients across three primary segments: Consumer & Brand, Employee Experience, and Corporate & Responsible Business. Its service portfolio spans seven capability areas — Reputation, Brand, Creativity, Employee Experience, Social, Influencer, and Sustainability — delivered through a "connected creativity" framework branded as "Do, Feel, Think." Notable technical components include the proprietary Fluency influencer platform, which combines deep-dive cultural research with influencer identification for brand campaigns, and the AI Merger Diagnostic, a six-question assessment tool launched to help organisations benchmark their AI integration maturity.
MSL UK generates revenue through quote-based professional services engagements with enterprise clients, with no publicly disclosed pricing tiers. The agency operates an enterprise field-sales motion, acquiring clients via direct outreach, referrals, thought leadership, and award recognition. Named clients span consumer electronics (Nintendo, Huawei, Panasonic), aerospace (Airbus), food and beverage (San Miguel, Subway, Nerds Candy), healthcare (Novartis, Boehringer Ingelheim, AXA Health), financial services (Citi), retail (ASOS, Currys, Screwfix), travel (TUI), entertainment (Disney+), and energy (Centrica). Several engagements are multi-year, including a four-year annual reporting partnership with ASOS and recurring work with PUMA, Airbus, and Centrica on ESG/annual reports. Campaign deliverables demonstrate measurable outcomes at scale, including an 11 billion global media reach for PUMA's Conference of the People campaign and a 9.6/10 NPS score for Novartis's TORCH leadership programme.
The agency employs between 251 and 500 staff and operates from a single headquarters at 40 Chancery Lane, London. Leadership includes a UK Group Managing Director overseeing both MSL and Salterbaxter, Managing Partners for Employee Experience, an Executive Creative Director, and heads of Delivery & Digital and Social & Influence. Recent strategic activity includes the 2025 AI Merger Diagnostic launch, the Hiring for Grit research partnership with Bridge of Hope Careers, and ongoing investment in the Employee Experience vertical.
