The new guaranteed-hours and cancelled-shift payment rights are expected to take effect in 2027, not immediately. The exact start date, reference period, hours thresholds, notice rules and payment formula are still being decided after a government consultation that closes on 25 August 2026. Before changing contracts or payroll calculations, speak to a firm providing accountancy services in Stockport so that you do not treat proposals as final law.
You should still improve your records now. The Employment Rights Act 2025 provides for guaranteed-hours offers, reasonable notice of shifts and payments when eligible shifts are cancelled, moved or cut short at short notice. Experienced Stockport payroll accountants can help build these checks into your payroll process.
Your rota, timekeeping and accounts will need to agree. Reliable small business bookkeeping services can help reconcile hours, gross pay and employer costs.
What has been decided and what remains open?
| Area | Current position | What you should do |
|---|---|---|
| Guaranteed hours | Qualifying zero-hours and low-hours workers will receive an offer reflecting hours worked during a reference period | Keep complete records of hours offered and worked |
| Reference period | The government prefers 12 weeks, but this is not final | Do not hard-code a 12-week rule |
| Worker choice | A worker can reject guaranteed hours | Record offers and responses |
| Shift notice | Eligible workers will have a right to reasonable notice | Time-stamp rotas and amendments |
| Cancelled shifts | Payment may be due when a shift is cancelled, moved or curtailed at short notice | Record who changed the shift, when and why |
| Start date | The measures are planned for 2027 | Monitor the final regulations |
The government says nearly 6 in 10 variable-hours workers receive less than 1 week’s notice of their shifts. That explains the reform, but not the final payroll rules.
How guaranteed hours could change payroll costs
The reform is not a complete ban on zero-hours contracts. A qualifying worker can reject an offer and remain on their existing arrangement.
Suppose a café assistant averages 18 hours a week during the eventual reference period. Depending on the final regulations, you may need to offer a contract reflecting that pattern. A variable payroll cost could therefore become a firmer contractual commitment.
Gross wages may rise during quiet periods, while employer National Insurance, workplace pension and holiday costs could also change. Review the current employer National Insurance rates and check whether you are using the Employment Allowance correctly.
Distinguish a genuine seasonal spike from a stable pattern. The guide to hiring your first employee is a useful starting point.
Why payroll will need better shift data
A total-hours figure at month-end may no longer be enough. Your system should be able to show:
- Hours offered, accepted and worked.
- The original shift date and time.
- When a shift was changed or cancelled.
- Who initiated the change.
- The worker’s applicable hourly rate.
Rota software, payroll and accounting software must communicate properly. Xero cloud accounting services can organise the accounting side, but the underlying shift data must still be accurate. The article on 5 payroll problems small employers can avoid covers common variable-pay errors.
How cancelled-shift payments could work
The calculation has not been finalised. The government is consulting on the notice period, payment percentage and possible exceptions.
Consider a worker booked for a 5-hour shift at £13.50 an hour. The planned gross pay is £67.50. If you cancel shortly before the shift, a statutory payment may become due once the rules begin. It would be unsafe to assume the worker must receive either £67.50 or nothing because the final formula is not known.
Create a separate payroll code for future short-notice payments instead of mixing them with ordinary hours. Wait for final guidance on PAYE, National Insurance and pension treatment. Records used for P60 preparation must reconcile with payroll submissions.
Forecast the wider business cost
Businesses in hospitality, care, retail, warehousing and events may feel the change most. Use management accounts for small businesses to model guaranteed wages and potential cancellation payments.
The guides to controlling spending with management accounts and management accounts versus year-end accounts explain why annual figures are too slow for workforce planning.
Cash flow matters too. Review how poor invoice tracking can damage cash flow and how Xero can support cash-flow monitoring. A limited company tax accountant can also make sure payroll costs are posted correctly in the accounts.
What you should do before the rules begin
- Audit each zero-hours, low-hours and agency arrangement.
- Compare contracted hours with hours regularly worked.
- Check whether rota changes are time-stamped.
- Keep evidence when a worker declines a shift or offer.
- Model wage, National Insurance, pension and holiday costs.
- Follow a regular bookkeeping checklist.
- Retain the records covered in the guide to small business financial records.
Frequently asked questions
Are zero-hours contracts being banned in the UK?
No. Workers will still be able to reject guaranteed hours and retain the flexibility of their existing arrangement.
When will the guaranteed-hours rules start?
They are expected during 2027. As of June 2026, the exact commencement date has not been announced.
Will every cancelled shift have to be paid?
Not necessarily. Eligibility, the short-notice period, exceptions and payment amount will be set by regulations.
