What Citi Health does

Citi Health LLP is a UK-based, female-owned workplace flu vaccination service provider founded in 2018 by Gayle Anderson and Michaela Longmore RGN, operating from London with nationwide coverage. The core offering is on-site flu vaccination clinics delivered to client workplaces by DBS-qualified nurses, each with over 20 years of clinical experience, with capacity of up to 180 vaccinations per day at large multi-site organisations and a minimum booking of 20 jabs for London. The company also runs occupational health assessments (return-to-work, rehabilitation, DSE compliance, risk assessments) coordinated by co-founder Michaela Longmore, and a central London standalone clinic available by appointment.

The underlying technology stack is modest: a GDPR-compliant online appointment booking system that lets employees self-manage their own clinic slots, and an encrypted occupational health reporting workflow that releases assessment reports to the employee first and then to the employer with consent, with a 7-day turnaround. There is no proprietary AI/ML, API, or mobile application; the platform is a standard web-based booking and reporting tool supporting the field-service delivery model.

Citi Health monetises on a quote-based, per-vaccination unit-pricing model for corporate clients, with sector-specific service packages for finance, law firms, schools/universities, media, recruitment, and film & TV production (including out-of-hours late-notice service). Distribution is direct-to-business via phone, email, and website form, supported by content marketing, social media (LinkedIn, Facebook), and an active Google Reviews presence (5.0 rating). The go-to-market targets HR departments as the buyer and positions the service as an extension of in-house wellbeing teams. A charitable 'Every Jab Gives Back' programme donates a portion of profits to Amref Health Africa UK (previously UNICEF), and the company operates with no external funding or institutional investors.
