Zero hours contracts can be a practical way to manage fluctuating demand, seasonal peaks, and last-minute rota changes - especially for small businesses.
But when someone on a zero hours contract calls in sick, it can quickly get confusing: do you have to pay them? If yes, how much? And what if their hours change every week?
This guide breaks down how SSP for zero hours contracts works in plain English, so you can handle absence properly, stay compliant, and reduce the risk of disputes.
We’ll cover who qualifies, how to work out eligibility, how to calculate payment when hours vary, and the practical steps you should take in your business.
What Is Statutory Sick Pay (SSP) And When Does It Apply?
Statutory Sick Pay (SSP) is the minimum legal sick pay that eligible employees are entitled to receive from their employer when they’re off work due to illness.
For employers, the key point is that SSP is not a “benefit” paid by the government - it’s paid by you through payroll (if the employee meets the rules). This article is general information only and isn’t tax, payroll or HMRC advice - if you’re unsure, check HMRC guidance or your payroll provider.
SSP In A Nutshell
- It’s a statutory entitlement (so it’s about legal eligibility, not discretion).
- It’s paid for qualifying days (days the employee is normally required to work, based on their working pattern or agreed arrangement).
- It usually starts after “waiting days” (the first 3 qualifying days of sickness are typically unpaid, unless waiting days have already been served in a linked Period of Incapacity for Work).
- It’s separate from contractual sick pay (you can offer more generous sick pay in your contract/policies, but you can’t offer less than SSP where it applies).
It’s also worth remembering that managing sick leave isn’t just about SSP. There can be wider employment law considerations around fairness, absence procedures, and disability-related adjustments (for example, under the Equality Act 2010).
Having clear rules in your Employment Contract and absence process in a Staff Handbook can help you stay consistent and avoid messy “it depends who the manager was” outcomes.
Do Zero Hours Workers Get SSP?
Often, yes - but not always.
The biggest myth we see in small businesses is: “They’re on a zero hours contract, so there’s no sick pay.” In reality, whether sick pay for zero hours contracts is due depends on whether the person meets the SSP eligibility rules.
SSP Eligibility: The Core Questions For Employers
When you’re working out SSP on a zero hour contract, the practical checks are usually:
- Are they an employee for SSP purposes? (SSP is primarily for employees; genuinely self-employed contractors won’t qualify, even if they work irregularly.)
- Are they on your payroll and have you paid them via PAYE?
- Are they sick for 4 or more consecutive days? (including non-working days)
- Do they earn at least the Lower Earnings Limit (LEL) on average? (this is assessed using average weekly earnings rules)
- Have they properly notified you of their sickness? (your absence reporting procedure matters here)
Being on a zero hours contract doesn’t automatically exclude someone. If they’re your employee and they meet the earnings and sickness criteria, zero hours sick pay may be payable as SSP.
Common Eligibility Scenarios
Example 1 (likely eligible): A hospitality employee is on a zero hours contract but usually works 4 shifts a week. They’ve been working for months, are on payroll, and their average weekly earnings are above the LEL. They’re off sick for a week. In many cases, SSP will be payable.
Example 2 (may not be eligible): A casual employee did one shift two months ago and hasn’t worked since. Their earnings don’t meet the LEL when averaged under SSP rules. They may not qualify for SSP.
Example 3 (watch the details): An employee has irregular work patterns, but there’s an ongoing arrangement where they accept shifts most weeks. Eligibility can turn on how you calculate average weekly earnings and how their qualifying days are identified under SSP rules.
This is why it’s so important to set expectations clearly in your Workplace Policy and absence reporting procedure - particularly for staff who don’t have fixed schedules.
How Do You Calculate SSP For A Zero Hours Contract?
Calculating SSP for a zero hours contract can be trickier because hours - and therefore pay - varies. But the process is still manageable if you break it down.
There are two key parts:
- 1) Are they eligible based on average weekly earnings (AWE)?
- 2) If eligible, what are their “qualifying days” and how many SSP days are payable?
1) Average Weekly Earnings (AWE) For Variable Hours
SSP eligibility often depends on whether the employee’s average weekly earnings are at or above the Lower Earnings Limit (LEL). For zero hours staff, you typically calculate this using HMRC’s “relevant period” rules (based on prior payday(s) before the sickness started).
In practice, this means you’ll usually look at:
- the employee’s earnings over a set number of weeks/paydays before the sickness started, and
- divide by the number of weeks in that period to get an average.
Because payroll setups vary (weekly vs monthly pay, irregular shift payments, etc.), it’s worth checking your payroll system can produce an AWE calculation and that your team knows how to use it.
2) Qualifying Days: The Part Employers Often Miss
SSP is paid for “qualifying days” - the days the employee is normally required to work under their arrangement.
For a fixed-hours employee, this is straightforward (e.g. Monday–Friday). For a zero hours employee, you may need to work out what their normal working pattern is, which can depend on:
- rota patterns you usually set,
- any standing expectations (e.g. “you normally work weekends”), and
- the employee’s history of accepted shifts (and when shifts are treated as confirmed).
Where businesses run into trouble is when they treat “no guaranteed hours” as “no qualifying days”. That can be risky. If the employee has an established pattern and you regularly roster them, there may still be qualifying days even if the contract says “zero hours”.
Waiting Days: Make Sure Your Payroll Team Applies Them Correctly
Usually, the first 3 qualifying days are “waiting days” (unpaid). SSP typically becomes payable from the 4th qualifying day of sickness.
However, linked periods of sickness can affect waiting days. Broadly, separate Periods of Incapacity for Work can be “linked” if they’re separated by 8 weeks or less, which can mean waiting days don’t apply again in the linked series. Getting this wrong can create underpayment issues (and sometimes it’s not the money - it’s the argument and the admin time that hurts most).
What Policies And Process Should You Have In Place For SSP And Sick Leave?
Even if you understand the technical rules, the real-life risk tends to come from inconsistent handling: different managers applying different standards, unclear reporting lines, or undocumented decisions.
If you want to manage zero hours contract sick pay situations smoothly, you’ll usually want a clear sickness process covering:
- How and when the employee must notify you (phone call vs text, who they contact, how early before the shift).
- When you require evidence (self-certification vs fit note).
- How you record sickness (dates, qualifying days, payroll notes).
- Return-to-work steps (a short check-in can prevent repeat issues and helps you spot underlying problems).
- How you handle frequent short-term absence (triggers, informal chats, and formal steps if needed).
Putting this into your Staff Handbook (and making sure it’s actually followed) will save you a lot of stress later.
Medical Evidence And Privacy: Don’t Over-Collect
Employers often want certainty, but you should be careful about how you request and store medical information. Health data is generally considered “special category” personal data under UK GDPR, so you should only collect what you genuinely need.
It’s also helpful to understand what you can (and can’t) ask - especially where the employee is reluctant to share details. A good rule of thumb is: request only what’s necessary to manage absence and pay, and keep it confidential.
When in doubt, it’s worth getting clarity on medical information expectations so your managers don’t accidentally pressure staff into disclosing more than required.
Fit Notes: Can You Disagree With A Doctor?
Sometimes employers suspect misuse of sick leave - especially where absences fall on busy periods or weekends. Even so, you need to respond carefully and fairly.
In many cases, a fit note is strong evidence of incapacity, and trying to ignore it without a proper basis can escalate matters quickly. If you’re worried about legitimacy, the better approach is usually to follow a proper process (and consider occupational health input where appropriate).
It’s useful to understand the risks around a doctor’s sick note before taking action.
Common Mistakes Employers Make With SSP For Zero Hours Contracts (And How To Avoid Them)
SSP disputes often come from preventable admin mistakes - not bad intentions. Here are some common pitfalls we see when employers manage SSP for zero hours contracts staff.
1) Assuming Zero Hours Means “No SSP”
As we’ve covered, eligibility depends on the legal criteria, not the label “zero hours”. If you automatically refuse SSP, you could end up with underpayment problems and a grievance.
2) Not Defining Qualifying Days Clearly
If your rotas are informal or your managers “just message shifts out”, it can be hard to evidence what counts as a qualifying day. You don’t need to overcomplicate it, but you do want consistency in:
- how shifts are offered,
- when shifts are confirmed, and
- how you treat sickness on confirmed shift days.
3) Inconsistent Absence Reporting Rules
If one manager accepts a WhatsApp message and another requires a phone call, you’ll quickly lose control of your sickness process.
Clear rules (and training) matter. That’s where a documented Workplace Policy can make a real difference.
4) Mixing Up SSP With Contractual Sick Pay
Some businesses promise “company sick pay” informally to be supportive - then later try to walk it back. That can create contractual expectations, even if you didn’t intend it.
If you want to offer enhanced sick pay, do it properly and set the rules clearly in writing (eligibility, evidence, waiting days, and when it can be withheld).
5) Mishandling Long-Term Or Recurring Sickness
If someone on a zero hours arrangement is repeatedly off sick or becomes long-term sick, you still need to manage it fairly. The fact their hours are variable doesn’t remove your obligations around procedure and discrimination risks.
At a certain point, you may need to consider capability steps, medical input, and whether there are reasonable adjustments that could help them return to work (especially if there may be a disability under the Equality Act 2010).
For a practical overview of the process, it can help to understand managing sick leave and how that connects with capability management.
Key Takeaways
- SSP for zero hours contracts is often payable if the employee meets SSP eligibility rules - zero hours status alone doesn’t exclude entitlement.
- To decide whether sick pay for zero hours contracts is due, check the sickness period (4+ consecutive days), notification, and whether their average weekly earnings meet the Lower Earnings Limit.
- For SSP on a zero hour contract, “qualifying days” can be a tricky area - keep rota practices consistent and well-documented.
- Use clear written rules in your Employment Contract and Staff Handbook so managers apply sickness reporting and evidence requirements consistently.
- Be careful with medical information - collect only what you need and handle it confidentially, especially as health data is sensitive under UK GDPR.
- If absence becomes frequent or long-term, manage it with a fair process and consider Equality Act risks and reasonable adjustments.
