Managing absence is one of the most challenging parts of running a small business. Since the major Employment Rights Act reforms took effect in April 2026, the rules surrounding Statutory Sick Pay (SSP) have become significantly more complex. If you are still relying on old habits: or worse, an outdated spreadsheet: you are likely making mistakes that could lead to financial penalties or employee disputes.
The new regime, monitored by the Fair Work Agency, prioritises transparency and fairness. For busy managers, this means there is no longer any room for "guesstimating" sick pay. You need a process that is both accurate and auditable.
In this guide, we will break down the seven most common mistakes SME managers are making with SSP today and provide practical steps to fix them.
1. Still Applying the "Waiting Days" Rule
For decades, UK employers didn't have to pay SSP for the first three days of an employee's illness. These were known as "waiting days." However, as of 6 April 2026, waiting days have been abolished.
The Mistake: Many managers are still telling staff that sick pay only starts from "day four." If your contracts or handbooks still mention a three-day waiting period, you are out of compliance.
The Fix: Update your internal documentation immediately. SSP is now payable from the first full day of sickness. Ensure your payroll software is configured to trigger payments from day one of any recorded incapacity.
2. Excluding Part-Time or Low-Earners
In the past, employees had to earn above the Lower Earnings Limit (LEL) to qualify for SSP. The 2026 reforms removed this threshold entirely.
The Mistake: Assuming that part-time staff or those on lower hourly rates aren't eligible for statutory pay. This "old school" approach now constitutes a breach of employment rights.
The Fix: You must treat all employees as eligible, regardless of their weekly earnings. Whether someone works five hours or forty, they are entitled to SSP from day one of their illness. This change makes tracking work patterns even more vital to ensure you are paying the correct amount based on their specific schedule.
3. Botching the "80% of Earnings" Calculation
The current weekly SSP rate is £123.25. However, there is a new "dual-check" rule. You must pay the lower of £123.25 or 80% of the employee’s Average Weekly Earnings (AWE).
The Mistake: Many SMEs simply apply the flat rate of £123.25 to everyone. For low-earning or part-time staff, 80% of their average pay might actually be less than the flat rate. Conversely, some managers fail to cap the pay at £123.25 for higher earners.
The Fix: You must perform a calculation for every sickness episode.
- Calculate the AWE over the 8 weeks prior to the sickness.
- Find 80% of that figure.
- Compare it to £123.25 and pay the lower amount.
Doing this manually is a recipe for disaster. Using a tool like LeaveWizard automates this logic, ensuring that the correct calculations are applied without you having to touch a calculator.
4. Failing to "Link" Periods of Sickness
Sickness periods are "linked" if they are 8 weeks (56 days) or less apart.
The Mistake: Treating every instance of sickness as a brand-new claim. If an employee is off for two days, returns for a month, and then goes off again, these periods are linked.
The Fix: When absences are linked, you must use the same AWE figure from the original claim. This ensures the 28-week maximum entitlement is tracked across the entire linked period. If you don't track these links, you might accidentally pay beyond the 28-week legal limit or use incorrect earnings data for the second absence.
5. Misidentifying "Qualifying Days"
SSP is only paid for "qualifying days": the days your employee is normally contracted to work.
The Mistake: Using a "one-size-fits-all" approach (like a standard Mon-Fri pattern) for staff who work irregular shifts or part-time hours. If you pay SSP for a Sunday to an employee who only works Tuesdays and Thursdays, you are overpaying. If you miss a Tuesday, you are underpaying.
The Fix: Maintain an accurate, digital record of every employee's specific work pattern. This is especially important for staff working from home or those with flexible arrangements. Your system should automatically know which days "count" as qualifying days for SSP purposes.
6. Keeping Sloppy Records
With the introduction of the Fair Work Agency, the UK government has signaled it will be much stricter about record-keeping.
The Mistake: Storing "sick notes" in various email folders or, worse, keeping verbal records of when people were off. If an inspector asks for an audit trail of your SSP calculations from six months ago, could you provide it in ten minutes?
The Fix: Centralise your records. You need a digital "paper trail" that includes:
- The start and end dates of the sickness.
- The qualifying days for that period.
- The AWE calculation used.
- Evidence provided (like a Fit Note for absences over 7 days).
Transparency is key. A structured, organized filing system protects you from claims of unfair treatment or underpayment.
7. Relying on "Messy Spreadsheets"
Spreadsheets were never designed to handle complex UK employment law. They are prone to broken formulas, version control issues, and human error.
The Mistake: Using an Excel sheet to track sickness, holiday, and SSP. Imagine an employee has a linked sickness period that overlaps with a bank holiday: calculating that manually in a spreadsheet is an invitation for errors.
The Fix: Move to a purpose-built platform. LeaveWizard was designed to replace the "wallchart and spreadsheet" nightmare. By using enterprise-grade logic, the platform handles the complexity of the 2026 rules for you. It knows the current rates, understands the 80% AWE cap, and flags linked periods automatically.

Summary: Protecting Your Business
The 2026 changes to Statutory Sick Pay are a significant shift for SMEs. While the removal of waiting days and the earnings limit makes the system fairer for employees, it places a much heavier administrative burden on you, the manager.
To avoid the most common mistakes:
- Audit your contracts to remove "waiting days."
- Verify your calculations against the 80% AWE cap.
- Ditch the spreadsheets in favour of a system that provides real-time compliance.
By automating these processes, you don't just avoid penalties: you regain the time to focus on growing your business. Ready to see how easy SSP compliance can be? Explore LeaveWizard today and take the guesswork out of your workforce management.
