ICB Mergers and Clusters: What You Need to Know

On May 20, 2026, the government launched radical pilot schemes across select NHS WorkWell sites and major employers to completely overhaul the broken fit note system. The goal is to move away from GPs signing off on sick leave and transition patients immediately to clinical and non-clinical community practitioners for personalised “stay in work” plans.
With over 11 million fit notes issued annually—and more than 90% signing workers off as completely “not fit for work”—the 2026 overhaul aims to curb economic inactivity by focusing on what employees can do, rather than what they cannot (Iacobucci, 2026). This guide breaks down exactly how the new system operates step-by-step.
The Blueprint: The primary goal is moving away from passive medical sign-offs toward active vocational rehabilitation.
WorkWell Teams: Instead of overstretched GPs managing long-term absences, patients connect with a dedicated team of work and health coaches, occupational therapists, and social prescribers (Iacobucci, 2026).
Early Intervention: The framework targets individuals right at the start of their illness cycle to prevent them from slipping into long-term benefit dependency (Gopal, 2026).
Self-Certification: Under UK employment law, workers can still self-certify an illness for the first 7 calendar days without any NHS documentation.
Day 8 Onward: If an absence passes one week, the employee enters the new primary care triage protocol.
Regional Models: Depending on the local Integrated Care Board (ICB) trial zone, patients are directed to either a GP-led referral pathway or directly into an integrated Work and Health Service (Iacobucci, 2026).
Barriers Analysis: Patients meet with a health coach to discuss the specific physical or psychological obstacles preventing a return to duty.
Job Demands Mapping: The practitioner evaluates the exact clinical limitations against the realistic workload and conditions of the current role (Gopal, 2026).
Tailored Plans: This evaluation generates a personalized data-dense file used to construct explicit, safe, and sustainable workplace adjustments.
Tripartite Alignment: The system ends the practice of forcing a patient to negotiate adjustments alone between a brief medical note and their employer.
Professional Outreach: WorkWell advisers contact the employer’s Human Resources or Occupational Health team directly to cross-reference necessary adjustments.
Consensus Agreement: All three parties formally agree to the specific parameters of a new, structured “Stay in Work” plan.
Phased Returns: Plans detail a gradual scaling up of hours over a set timeframe to rebuild stamina safely.
Amended Duties: High-stress, heavy lifting, or incompatible physical tasks are temporarily removed or altered.
Statutory Sick Pay (SSP): If an employer cannot logistically fulfill the adjustments outlined, the digital plan automatically defaults to certifying the patient as “Not fit for work,” protecting their eligibility for standard sick pay (Gopal, 2026).
