Every worker in the UK is entitled to paid holiday. Here’s exactly how much, how it’s calculated, and what to do if you’re not getting what you’re owed.
Statutory Holiday Entitlement
Worker type
Entitlement
Full-time (5 days/week)
28 days (5.6 weeks)
Part-time (3 days/week)

Part-time (2 days/week)
11.2 days
Part-time (4 days/week)
22.4 days
Irregular hours/zero hours
12.07% of hours worked (accrual method)
The maximum statutory entitlement is 28 days — if you work 6 or 7 days a week, you still only get 28 days minimum by law (though your employer can offer more).

Part-Time and Bank Holidays
Detail
How it works
Do part-timers get bank holidays?
Pro-rated — if bank holidays fall on days they don’t work, they may need equivalent time off on other days
Example
Worker does Mon-Wed. Bank holiday is on Monday. They get the day off. If bank holiday is on Friday (a non-working day), they should get an equivalent day added to their allowance
Irregular Hours and Zero Hours Contracts
Since January 2024, the calculation for irregular hours workers changed:
Method
Detail
Accrual rate
Holiday accrues at 12.07% of hours worked in each pay period
Rolled-up holiday pay
Employer can add 12.07% to your hourly rate instead of giving separate paid time off
Who counts as irregular hours?
Workers whose paid hours are wholly or mostly variable — zero hours contracts, casual workers, agency staff
Example: Zero Hours Worker
Detail
Amount
Hours worked this month
80 hours
Holiday accrued
80 × 12.07% = 9.66 hours
Hourly rate
£12.00
Rolled-up holiday pay option
£12.00 × 12.07% = £1.45 extra per hour (total £13.45/hour, no separate paid leave)

Up to 8 days (1.6 weeks) — if employer agrees
Sick and couldn’t take holiday
Yes — up to 4 weeks can be carried over to the next year (and up to 18 months)
Maternity/paternity leave

Holiday During Notice Period
Situation
Rules

Yes — but must give notice equal to twice the holiday period (e.g. 2 days’ notice for 1 day’s holiday)
Can you request holiday during notice?

Untaken holiday when you leave

Taken too much holiday when you leave
Employer may deduct from final pay (if contract allows)
Common Problems
Problem
Your rights
Employer says you have no holiday entitlement
Unlawful — all workers get 5.6 weeks minimum
Employer includes bank holidays but only gives 20 days
That’s the minimum (20 + 8 = 28). Legal but not generous
Employer won’t let you take holiday
They can choose when you take it, but can’t prevent you entirely
Not being paid during holiday
Unlawful — holiday must be paid at your normal rate
Holiday pay doesn’t include regular overtime
Should be included — raise with employer or ACAS
“Use it or lose it” policy with no carry over
Your employer must allow carry over of 1.6 weeks if you couldn’t take it
Agency worker not getting holiday
You’re entitled from day one — raise with agency
What to Do If You’re Not Getting Your Entitlement
Step
Action
1
Check your contract — what does it say about holiday?
2
Raise it informally with your manager or HR
3
Put it in writing — email creates a paper trail
4
Contact ACAS for advice: 0300 123 1100
5
Consider an employment tribunal claim (within 3 months minus 1 day of the issue)
