How UK holiday entitlement is calculated
Almost every worker in the UK is entitled to 5.6 weeks of paid holiday a year. For someone who works a five-day week that is 28 days. The figure is a cap as well as a minimum: a worker on six or seven days a week is still entitled to 28 days by law, although many contracts give more. When the contract gives more than the statutory minimum, the contractual figure is the one that applies, and this calculator uses whichever is higher.
Part-time workers
Part-time workers get the same 5.6 weeks, measured in their own working week. Multiply the days worked each week by 5.6: three days a week gives 16.8 days, four days gives 22.4 days. Half days are allowed, so two and a half days a week gives 14 days. Treating part-time staff less favourably than full-time colleagues is not allowed, so the same rule applies to any extra contractual days on a pro-rata basis.
Bank holidays
There is no automatic right to paid leave on bank holidays. An employer can count them as part of the 28 days or give them on top. England and Wales normally have 8 bank holidays, Scotland 9 and Northern Ireland 10. If a full-time worker’s 28 days include the 8 bank holidays in England and Wales, they have 20 days left to book.
New starters and leavers
In their first leave year, a new starter builds up holiday at one-twelfth of the yearly entitlement at the end of each complete month. Any fraction other than a half day is rounded up to the next half day. The calculator also shows the straight pro-rata figure for the rest of the leave year, which is what they will have earned by the end of it. When someone leaves, they are due their yearly entitlement in proportion to the part of the leave year they worked, minus what they have already taken. A positive figure is holiday owed, usually paid in the final pay; a negative figure is holiday taken in excess, which can only be recovered if the contract says so.
