If you’re an employee you’re likely to continue to receive some money if you’re too ill to work, at least initially. You can get this in one of two ways.
If your company has a sick pay scheme, they will pay you as outlined in your contract of employment. This might be less than you’d normally be paid, but it can’t be less than Statutory Sick Pay (SSP).
If you’re earning at least £109 a week, you can claim SSP after you’ve been off work for more than four days.
SSP is currently £86.70 a week (based on current data from the Department of work and pensions.) It’s paid by your employer for up to 28 weeks. Once this stops, you may be able to qualify for Employment and Support Allowance (ESA). This replaces Incapacity Benefit and is paid by the Department of Work and Pensions. Those who are employed and don't earn enough to receive SSP and the self employed can apply for ESA after three weeks.
