General information, not employment law advice. Day-based results assume an 8-hour day, and entitlement above the statutory minimum is a matter for the contract. Check the contract and the current legislation before acting on a number.

Where 5.6 weeks and 12.07% come from

Almost every UK worker is entitled to 5.6 weeks of paid holiday a year, capped at 28 days for anyone working five or more days a week. Part-time staff get the same 5.6 weeks, applied to their own working pattern — a three-day-a-week worker gets 16.8 days.

The 12.07% figure is the same entitlement expressed differently. A year has 52 weeks; take off the 5.6 weeks of holiday and 46.4 working weeks remain. 5.6 ÷ 46.4 = 12.07%. So every hour worked accrues 12.07% of an hour of paid holiday, which is why it is the practical method for irregular-hours staff.

Applies UK-wide

Statutory holiday entitlement is set UK-wide. Unlike business rates, there is no England-only variation here.

The common mistake

Treating the 28-day cap as the entitlement for everyone. It is a cap, not a target — a four-day-a-week worker is entitled to 22.4 days, not 28, and a six-day worker is capped at 28 rather than 33.6.

Stop working holiday out in a spreadsheet

ClockRota tracks accrual as shifts are worked, so entitlement is a number you look up rather than one you rebuild every quarter. Free while we're in public beta, then £9/month for teams up to 5.
