Frequently asked questions
What is Statutory Sick Pay (SSP)?
SSP is the minimum sick pay employers must pay in the UK. It's £116.75 per week (2024-25) for up to 28 weeks. You must earn at least £123/week to qualify.
Do I have to use sick leave for doctor appointments?
This depends on company policy. Some employers require sick leave for appointments, others allow flexible time. Many distinguish between planned and unplanned medical time.
Can unused sick leave be paid out?
Unlike annual leave, most employers do not pay out unused sick leave. Some accruing systems allow sick bank donation or conversion to other benefits.
What if I run out of sick days?
You may need to use annual leave, unpaid leave, or short-term disability insurance. In the UK, SSP provides a safety net for eligible employees.
