| + | **For failure to revalidate every 5 years** | ||
| + | |||
| + | As of November 2025 Ofcom had only ever revoked amateur licences on one occassion for failure to revalidate in the previous 5 years. | ||
| + | |||
| + | Ofcom found the revocation procedure was labour-intensive and expensive they never repeated the exercise, no further licences were revoked. | ||

| + | |||

At the end of that period if no appeal is submitted the licence will be revoked. | ||
