Holiday Entitlement When Starting a New Job Mid-Year

How mid-year entitlement works

If you start a new job part-way through your employer's holiday year, your entitlement is pro-rated for the portion of the leave year remaining.

Formula: (Days remaining in leave year ÷ 365) × 28 days

Example: Start 1 July with Jan–Dec leave year → (184 ÷ 365) × 28 = 14.1 days

The accrual method

Holiday entitlement accrues at roughly 2.33 days per month for a full-time worker. Your employer may restrict you to taking only what you have accrued so far — not your full annualised figure.

Does the leave year matter?

Yes. Your employer's leave year may run April–March, January–December, or on your start anniversary. Check your contract to confirm.

What about bank holidays mid-year?

If your contract includes bank holidays, only those falling within your remaining period count toward your pro-rated total. Starting July means roughly 4 bank holidays (July–December).

Check your contract

Some employers offer enhanced terms for mid-year starters. Always check your contract or ask HR. If nothing is specified, the statutory pro-rata calculation applies.

Calculating it step by step

When you start part-way through a leave year, statutory holiday is pro-rated on a calendar basis. The calculation has three inputs: the full-year entitlement for your working pattern, the number of days from your start date to the end of the leave year, and the length of the leave year.

Formula: (days employed ÷ days in the leave year) × full-year entitlement

A five-day-week worker's full-year entitlement is 28 days. If your contract gives more than the statutory minimum, pro-rate the contractual figure instead — it will usually be the better one.

Worked example: starting 1 September

The leave year runs 1 January to 31 December, you work five days a week, and you start on 1 September. That leaves 122 days in the year.

28 × (122 ÷ 365) = 9.4 days for the rest of that leave year.

The same arithmetic works for any pattern. Four days a week: 22.4 × (122 ÷ 365) = 7.5 days. Three days: 16.8 × (122 ÷ 365) = 5.6 days.

Some employers calculate from your start date to the anniversary rather than to the end of the calendar leave year. That is lawful if applied consistently, but it must not leave you with less than the statutory minimum over the year.

Probation does not pause your holiday

Holiday accrues from day one, including during a probationary period. A contract cannot withhold statutory holiday until probation is passed. It is common — and lawful — for an employer to restrict when you can take it (for example, no leave during a notice period without agreement), but the entitlement itself accrues regardless.

If you are dismissed during probation having taken more holiday than you accrued, the employer may seek to recover the excess only where the contract provides for it, and subject to National Minimum Wage limits on deductions.

Fixed-term, agency and casual starters

A fixed-term contract of less than a year still carries the same 5.6 weeks, pro-rated to its length — not zero. Agency workers are entitled to statutory holiday from the agency, and casual or zero-hours starters accrue under the 12.07% method for irregular hours.

The practical trap for mid-year starters is the payslip: check that your first payslip shows an accrual figure and that it increases each month. If it shows a flat zero until January, your employer is probably running an anniversary scheme — fine if it delivers the statutory total, not fine if it does not.
