GP Practice List Size & Workload Calculator

Understand the relationship between list size, appointment demand, and workforce capacity. Helps make the case for additional resource.

## List Size & Workload Analysis

### England Benchmarks 2024

- Average GP list size: 2,200 patients/WTE GP

- BMA recommended maximum: 1,800 patients/WTE GP

- Average consultations per patient per year: 4.2

- Appointments needed per 1,000 patients/week: 95–110

### Step 1 — Patients per GP

Total list ÷ WTE GPs = patients per GP

- <1,800: sustainable | 1,800–2,200: stretched | >2,200: under significant pressure

### Step 2 — Weekly Demand

List size × 0.10 = estimated weekly appointment demand

Compare to actual slots available

### Step 3 — ARRS Contribution

Each FTE ARRS clinician adds ~20–25 appointments/day

### Making the Business Case

"We have X patients per WTE GP against a recommended maximum of 1,800. We generate Y requests/week against a capacity of Z. One additional ARRS role would add approximately N appointments per week."
