Being signed off sick affects your Universal Credit because your earnings change. UC adjusts each assessment period based on actual earnings, so lower earnings from sickness generally means a higher UC payment. But there are also important longer-term implications if illness is expected to last.
Universal Credit is assessed on earnings in each monthly assessment period. If you are off sick and not earning, your UC award increases to reflect the lower income. If you receive Statutory Sick Pay (SSP), this counts as earnings for UC purposes. SSP in 2026/27 is £116.75 per week (payable from day four of sickness). Your UC award will be calculated based on SSP earnings rather than your normal wage.
SSP is paid by your employer for up to 28 weeks if you are sick and employed, earning at least £123 per week, and have provided a fit note after the first 7 days. After 28 weeks, SSP ends. If you are still unfit for work at that point, new-style Employment and Support Allowance or the UC LCWRA element may apply depending on your NI contributions and circumstances.
If your sickness is expected to last more than three months, you should report it to DWP via your UC journal. A fit note from your GP or doctor should be uploaded. DWP will then consider whether to refer you for a Work Capability Assessment (WCA). If the WCA finds you have Limited Capability for Work and Work-Related Activity (LCWRA), your UC award increases by £429.80 per month. All work-related requirements are also suspended.
You are not expected to actively search for work while you are genuinely unable to do so. If you have provided a fit note, work search requirements are typically suspended during the period it covers. Once the fit note expires, conditionality may resume unless a WCA is in progress or a LCWRA determination has been made.
Report the change via your journal as soon as you know sickness is likely to last. Upload fit notes promptly. Contact your work coach if you have concerns about conditionality. Request a WCA referral if the condition is expected to last more than three months. Keep the DWP updated each time a fit note is renewed, do not let the note lapse without renewal or conditionality will restart.
