Zero-Hours Contract Rights UK 2026: Pay, Tax, Holiday & New Rules

UK zero-hours contracts give the employer flexibility to offer work as needed and the worker flexibility to accept or decline. The trade-off is unpredictable income and historically weaker protections. The Employment Rights Bill 2024 (in force from various dates through 2025-2026) materially strengthened zero-hours workers' rights - including the right to request guaranteed hours and clearer holiday pay rules. This guide covers the 2026/27 position.

What a zero-hours contract is

A zero-hours contract is one where the employer doesn't guarantee any minimum hours of work, and the worker isn't obliged to accept any offered shifts. Both sides have flexibility but neither side has commitments.

The arrangement is widely used in:

• Hospitality (hotels, restaurants, cafés)
• Retail (especially seasonal cover)
• Care work (domiciliary, sleep-in)
• Agriculture (harvest seasons)
• Education (supply teaching, occasional lecturing)
• Events and conference work

Many zero-hours workers have regular patterns despite the contract - e.g. consistently 25 hours/week for years, even though the contract says zero is the minimum.

Your minimum legal protections

Regardless of the "zero" hours in the contract, you have the same statutory rights as any worker:

National Minimum Wage / National Living Wage

Apply per hour worked. For 2026/27:

• £12.21/hour for workers aged 21+ (NLW)
• £10.00/hour for 18-20
• £7.55/hour for under-18 + apprentices in their first year

See our NMW guide for the full age-band table and underpayment patterns.

Holiday entitlement and pay

Statutory minimum: 5.6 weeks paid holiday per year, accrued in proportion to hours worked.

Holiday pay calculation (post-2024 rules): average earnings over the previous 52 paid weeks, including overtime / shift premiums / commission. Skip weeks of zero pay.

Two delivery routes:

• Take leave when you want it: paid at the calculated 52-week average for that period.
• Rolled-up holiday pay (re-permitted from 2024 for irregular-hours and part-year workers): an extra 12.07% on every pay packet, clearly itemised on your payslip. The employer cannot bundle this into the hourly rate.

See our holiday pay guide for the full calculation.

Statutory Sick Pay (SSP)

SSP applies if you've been absent for at least 4 consecutive days AND you earn at least the Lower Earnings Limit (£123/week in 2026/27).

For zero-hours workers with irregular earnings, the LEL test can be tricky - you must hit the threshold for the relevant qualifying period. The Employment Rights Bill removed the 4-day waiting period (so SSP becomes payable from day one) and removed the LEL threshold (so all workers qualify regardless of weekly earnings) - these changes phase in through 2025-2026.

Statutory Maternity / Paternity / Shared Parental / Adoption Pay

Apply if you meet the qualifying conditions (continuity of employment + earnings above LEL during the qualifying weeks). For zero-hours workers, qualifying-week earnings can be variable; check carefully against the relevant statutory pay rules.

Pension auto-enrolment

You're auto-enrolled if you earn over £10,000/year AND are aged 22 to State Pension age. Below £10,000/year, you can opt-in voluntarily.

For zero-hours workers, eligibility is assessed each pay period. A surge in earnings that pushes you above the per-period equivalent of £10,000/year triggers enrolment from that period onwards.

Employment Rights Bill 2024 - new protections

The Employment Rights Bill 2024 introduced material changes for zero-hours workers, phasing in through 2025-2026:

Right to request guaranteed hours (key new right)

If you've worked regularly under a zero-hours contract for 12+ weeks, you can request a contract guaranteeing the hours you've actually been working. The employer must offer a contract reflecting your average hours unless they have specific business grounds to refuse.

Practical effect: if you've been doing 25 hours/week for 6 months, you can request a contract guaranteeing those 25 hours. The employer can no longer keep you on a "0 minimum" contract indefinitely if your actual pattern is regular.

Reasonable notice of shifts

Employers must give reasonable notice when offering or cancelling shifts. Late shift cancellations now trigger a payment-for-the-cancelled-shift requirement.

The "reasonable" standard is set by Acas Code of Practice and varies by sector - typically 24-48 hours notice for shift changes.

Compensation for cancelled shifts

If your employer cancels a shift at short notice (within the "reasonable notice" window), they must pay you compensation. The exact amount depends on the Code of Practice but is materially higher than zero (which was the previous default).

Exclusivity clauses banned (since 2015, reinforced)

Exclusivity clauses (terms preventing you from working for other employers) have been unenforceable in zero-hours contracts since 2015. The Employment Rights Bill closed loopholes around effective exclusivity (e.g. "you can work elsewhere but only with our written permission").

You're free to take work from other employers without restriction.

How tax works on zero-hours income

Zero-hours work is ordinary employment income. Standard PAYE + Class 1 NI rules apply:

• Income tax via PAYE at your tax-code rate.
• Class 1 NI at 8% above £12,570 annual (per pay period thresholds: £241/week or £1,047.50/month).
• Pension contributions if auto-enrolled.

The complications come from variable hours:

Tax code on irregular earnings

Your tax code applies cumulatively. Periods with no work mean your unused Personal Allowance accumulates and can be used in busier periods - this auto-balances over the year if your code is cumulative (no W1/M1/X suffix).

Common error: a zero-hours worker who occasionally has weeks of zero earnings ends up on a non-cumulative code, which over-deducts in busier weeks. If you spot this, ask payroll to confirm your code is cumulative.

Working multiple zero-hours jobs

Multiple low-hours jobs each provide some Class 1 NI contribution but only ONE qualifying year per tax year. If your combined earnings exceed the LEL (£6,396), you have your year credited; multiple sub-LEL jobs may collectively exceed it but no single one provides the credit.

Check your NI record annually via your Personal Tax Account and pay voluntary Class 3 NI for any gap years (see our State Pension top-ups guide).

Universal Credit interaction

If you're on UC, your variable monthly earnings affect your monthly UC payment. The 55% taper rate applies above your work allowance. See our Universal Credit guide.

The "two-paydays-in-one-period" trap is especially common for zero-hours workers paid weekly or fortnightly.

Common payslip errors for zero-hours workers

1. Wrong NMW rate applied (especially after a birthday triggers a higher band).
2. Missing rolled-up holiday pay line when the employer claims to apply it but doesn't itemise it separately.
3. Holiday pay calculated on basic hourly rate only instead of the 52-week average.
4. Tax code stuck on W1/M1/X despite no recent job change.
5. Pension auto-enrolment missed when earnings spike into eligibility for one period.
6. Travel time between clients unpaid (relevant for domiciliary care workers - that time is working time).
7. Sleep-in active hours unpaid (see our sleep-in shifts guide).

Where to escalate

Issue	Try first	If unresolved
Hours worked but not paid	Payroll, in writing	Acas 0300 123 1100
NMW underpayment	Payroll, in writing	HMRC NMW enforcement (up to 6 years arrears)
Holiday pay below 52-week average	Payroll	Acas
Refused guaranteed-hours request	HR / Acas	Employment Tribunal (under Employment Rights Bill)
Cancelled-shift compensation withheld	HR / your union	Acas, then Employment Tribunal

When to talk to a union or solicitor

For substantial unpaid wages, denied holiday pay, or contested guaranteed-hours requests where the employer has wrongly refused, contact your union (UNISON, GMB, Unite, USDAW depending on your sector) or Citizens Advice. For tribunal claims, a no-win-no-fee employment solicitor takes the bigger cases.
