If you employ even one person, the rules around day-one employment rights are shifting under you, and some changes have already landed. From April this year statutory rates rose, and reforms to sick pay are moving towards paying employees from the first day of illness rather than the fourth. The direction of travel is clear: more protections apply from the moment someone starts, not after months of service.
The short answer for a busy owner-manager is this. The Employment Rights Act 2025 is now law, but it does not switch everything on at once. Government is rolling out the changes in stages through 2026 and 2027, with detailed regulations and consultations filling in the specifics. Some pieces are live, some are imminent, and the smart move is to get your contracts, sick pay process and HR admin ready now rather than scrambling later.
What “day-one rights” actually means
A “day-one right” is a legal entitlement an employee has from their first day of work, with no qualifying period. Plenty already exist: protection from discrimination, the right to a written statement of employment particulars, the national minimum wage, and statutory family leave entitlements. The big legislative story is that the list is growing, and one long-standing barrier is set to go.
The headline reform is unfair dismissal. Historically an employee needed two years’ continuous service before they could bring an ordinary unfair dismissal claim. The Employment Rights Act removes that qualifying period so the protection becomes a day-one right, subject to a lighter-touch process during an initial period for new starters. This is one of the changes scheduled for later in the rollout (widely expected in 2027), so you have time, but not forever.
For a small employer the practical message is simple. Casual, undocumented dismissals of newer staff will carry more legal risk. Fair process, written reasons and honest probation reviews stop being nice-to-haves and become your protection.
Sick pay: the change already in motion
Statutory Sick Pay (SSP) is where the “day-one” idea bites soonest for cash flow. Two features have long limited SSP: a three-day waiting period before it is payable, and a lower earnings limit that excludes the lowest-paid workers. The reforms remove both, so SSP becomes payable from the first qualifying day of sickness and extends to lower earners, with a percentage-based rate for those below the usual threshold.
What does this mean for a small business? More short absences will attract SSP, and payroll needs to calculate it correctly from day one. If you run a shop, café or care business with several part-time staff, the effect on your monthly wage bill is real and worth modelling. Our guide to cash flow forecasting using the 13-week method is a sensible way to see how the extra cost lands across a quarter.
The other changes worth diarising
Beyond dismissal and sick pay, the Act touches several areas that matter to smaller employers:
- Zero-hours and low-hours working: new duties around offering guaranteed hours that reflect a regular working pattern, plus reasonable notice of shifts and payment for cancelled shifts at short notice.
- Fire and rehire: tighter limits on dismissing staff to re-engage them on worse terms.
- Flexible working: requests strengthened, with employers needing to justify refusals more robustly.
- Family and bereavement leave: several entitlements moving to day-one status.
- Harassment: a stronger duty to prevent it, including from third parties such as customers.
Exact commencement dates and the fine print arrive through regulations, so treat the official gov.uk Employment Rights Act pages and Acas guidance as your live reference. Acas in particular publishes plain-English updates that are ideal for a non-specialist owner.
What you should change in your paperwork
You do not need a legal degree to get ahead of this. Most of the risk for a small employer comes from missing paperwork and inconsistent process, not from the law being impossibly complex.
- Contracts and offer letters: make sure every employee has a compliant written statement of particulars on or before day one. If you are taking on staff for the first time, our complete 2026 checklist for hiring your first employee walks through the essentials.
- Probation process: document objectives, hold recorded check-ins, and give clear feedback. With day-one unfair dismissal on the horizon, a fair and evidenced probation is your best defence.
- Sick pay policy: update it to reflect payment from day one and how you record absence.
- Shift and rota practices: if you use casual or variable hours, start logging patterns so you can meet guaranteed-hours and notice rules.
Software that helps you stay compliant
Getting this right by hand is possible but tedious. HR and payroll software takes the strain by generating compliant contracts, tracking absence, calculating SSP correctly and keeping an audit trail of probation reviews. Several UK-friendly options are worth shortlisting, and naming them saves you the search.
On the HR side, BrightHR, Breathe and Sage HR are popular with smaller employers, while Employment Hero combines HR and payroll in one place. For payroll specifically, Xero and QuickBooks handle SSP and RTI submissions to HMRC alongside your bookkeeping. If you want advice as well as software, providers such as Peninsula and Citation bundle HR documentation with helpline support.
| Tool | Best known for | Typical pricing model |
|---|---|---|
| BrightHR | HR admin, absence tracking, document storage for small teams | Subscription tiers, usually priced per employee |
| Breathe | Simple, UK-focused HR for very small businesses | Monthly tiers based on headcount |
| Sage HR | Modular HR that scales as you grow, integrates with Sage payroll | Per-employee, per-module pricing |
| Employment Hero | Combined HR and payroll in one platform | Subscription, typically per employee |
| Xero / QuickBooks | Payroll with SSP calculations and HMRC submissions | Monthly plan plus a per-payslip or per-employee add-on |
As a rough guide, dedicated HR software for a small team tends to run at a few pounds per employee per month, while payroll is usually a modest monthly plan plus a small per-employee charge. Check current prices on each vendor’s site, as tiers change.

Frequently asked questions
Are all these changes live right now?
No. The Employment Rights Act 2025 is law, but the government is switching on measures in phases through 2026 and 2027. Some rate changes and early reforms have already taken effect, while bigger items such as day-one unfair dismissal protection are scheduled for later. Check gov.uk and Acas for the current commencement dates.
Do these rules apply to a business with only one or two staff?
Yes. Employment rights generally apply regardless of how many people you employ. There is no “too small to matter” exemption for the core duties, so a two-person firm needs compliant contracts and a fair process just as a larger one does.
How will day-one sick pay affect my costs?
Removing the waiting period means SSP is payable from the first qualifying day, and extending it to lower earners brings more part-time staff into scope. Expect short absences to cost slightly more. Model it across a quarter so there are no surprises in your wage bill.
What is the biggest risk if I do nothing?
Dismissing a newer employee informally, without documented reasons or a fair process, once day-one unfair dismissal protection is in force. Missing written statements of particulars and mishandling SSP are the other common traps. All three are avoidable with basic paperwork and a consistent routine.
Do I need an HR adviser or is software enough?
For straightforward setups, good software plus Acas guidance is often enough. If you have variable-hours staff, tricky performance issues or a possible dismissal, a paid adviser or an HR platform with a support line is worth the money. It is far cheaper than defending a claim at an employment tribunal.
What to do next
- Audit your paperwork this month: confirm every employee has a compliant written statement, and refresh your sick pay and probation policies.
- Update your sick pay process: make sure payroll calculates SSP from day one and check the impact on your cash flow.
- Choose a tool: shortlist an HR or payroll platform such as BrightHR, Breathe, Sage HR, Employment Hero, Xero or QuickBooks and get your records and templates in order.
- Bookmark the official sources: follow the gov.uk Employment Rights Act pages and Acas updates so you act on each stage as it goes live, not after.
