Day-One Sick Pay: What the 2026 SSP Change Now Costs You for Every Flu Absence
Published: June 24, 2026
Last Updated: June 27, 2026
Until this April, the first three days of a sick employee’s absence cost you nothing in Statutory Sick Pay. Since 6 April 2026, they do. For an illness as common as flu, that quietly changed the maths on every workplace flu programme — and most employers have not recalculated.
This is a short, practical look at what the day-one SSP change means for the real cost of flu absence in your workforce, and the cheapest lever you have to bring it down.
What actually changed (the short version)
Three things took effect on 6 April 2026 under the Employment Rights Act 2025:
- SSP is now payable from the first qualifying day of sickness — the three “waiting days” are gone.
- The lower earnings limit has been removed, bringing around 1.3 million more workers into eligibility.
- SSP is paid at £123.25 a week, or 80% of normal weekly earnings, whichever is lower.
Put together: more of your people now qualify, and you start paying sooner.
Why this lands hardest on flu
Flu is one of the most common causes of multi-day winter absence, and it tends to hit a lot of people in a short window. A typical bout keeps someone off for the best part of a week.
Under the old rules, that absence cost you SSP only from day four. Now it is from day one — three extra paid days for every flu absence, multiplied across your workforce and the whole season.
SSP now works out at roughly £24.65 a day (£123.25 a week). The three waiting days that used to cost you nothing now cost about £74 per absence. Across a workforce of 200 where, say, one in ten catches flu, that is around £1,500 in new SSP cost for flu alone — before you count a single hour of lost output.
The bigger cost SSP does not show
SSP is only the visible number. The larger cost is lost output: the work that does not get done while someone is off, the colleagues who cover, and the people who come in unwell and pass it on. One flu case rarely stays one flu case — it ripples through a team.
So the day-one change is not really the whole story. It is the part that now shows up clearly on your payroll, on top of a productivity cost that was always there.
How the maths now flips in favour of vaccination
Here is the shift that matters. A workplace flu vaccination used to be filed under “nice perk.” With SSP running from day one, it is straightforward cost control: every case you prevent saves the sick pay and the lost output that came with it.
For most roles, a single vaccination costs a fraction of even one day’s lost productivity — and far less than a multi-day paid absence. The cheapest lever you have on flu absence is simply uptake: getting as many of your people protected as possible, as easily as possible.
The day-one SSP change does not make flu more likely — it makes every flu absence more expensive. That tilts the cost-benefit of vaccination further in your favour, and makes the percentage of your workforce that actually gets vaccinated the number worth focusing on.
What you can actually do about it
Uptake comes down to convenience. A few practical moves:
- Make it easy to access. On-site clinics work for office-based teams; flu vouchers cover remote and multi-site staff who can redeem at a local pharmacy.
- Only pay for jabs that happen. A pay-per-activation voucher model means you are not paying for vouchers nobody uses.
- Time it right. Aim to have people protected before the season peaks, rather than mid-outbreak.
- Track uptake year on year, so you can see the absence cost you are designing out.

Frequently asked questions
Do employers pay SSP from day one now?
Yes. Since 6 April 2026, Statutory Sick Pay is payable from the first qualifying day of sickness — the three waiting days have been removed.
How much is SSP in 2026?
£123.25 a week, or 80% of the employee’s normal weekly earnings, whichever is lower. The lower earnings limit has also been removed, so more workers now qualify.
Does the change affect the cost of flu absence?
Yes — directly. Because flu absences typically run several days, you now pay SSP from the first day rather than the fourth, which adds up across a workforce over the season.
Can flu vaccination reduce sick pay costs?
Indirectly, yes. Fewer flu cases means fewer paid absences and less lost output. With SSP now starting on day one, preventing cases has a clearer financial payback than before.
When did the day-one SSP rule take effect?
6 April 2026, under the Employment Rights Act 2025.
Who pays for a workplace flu vaccination?
The employer. A workplace flu jab can usually be treated as a tax-exempt “trivial benefit,” though it is worth confirming the position with HMRC for your circumstances.
