Unlimited Holiday Policies in the UK: How They Really Work in 2026/27

The legal floor that "unlimited" can't remove

Unlimited holiday policies have become a fashionable perk, especially among tech companies and firms trying to signal trust in staff autonomy. But UK employment law doesn't have an "unlimited" category — it has a statutory minimum that every worker is entitled to regardless of what their employer calls the policy. Under the Working Time Regulations, full-time workers are entitled to at least 5.6 weeks of paid annual leave per year. For someone on a standard 5-day working week, that works out to 28 days, and this figure already includes the 8 UK bank holidays if your employer chooses to count them as part of your allowance rather than on top of it.

This means an "unlimited holiday" policy is, legally speaking, just an employer promising more generous access to leave than the statutory floor — it is not a replacement for the floor. If an employer ever tried to argue that "unlimited" meant employees had given up their right to a guaranteed minimum, that would not hold up; the 5.6-week entitlement is a statutory right that cannot be contracted out of. You can check exactly how your own leave year breaks down, including bank holidays, with

Worked example 1: Full-time statutory floor

James works full-time, 5 days a week, under his employer's unlimited holiday policy. Whatever the marketing language says, he is still legally guaranteed a minimum of 28 days of paid leave across the year (5.6 weeks x 5 days). If his employer's culture means people rarely take more than that anyway, the "unlimited" label hasn't actually changed his statutory position at all — it's simply removed the fixed number his contract might otherwise have quoted.

Why "unlimited" can sometimes mean less time off, not more

Multiple workplace surveys have found a counter-intuitive pattern: employees under unlimited holiday policies often take fewer days off per year than colleagues with a clearly defined allowance like 25 or 28 days. Without a visible number ticking down, there's no natural prompt to book leave, and workers can feel uncomfortable taking "too much" time off when there's no explicit ceiling to benchmark against. Manager approval also remains a gatekeeping step — an unlimited policy is discretionary, so requests can still be declined based on project deadlines, team cover, or seasonal business needs, just as they would be under a fixed allowance.

This creates a practical tension: the policy is marketed as a generous, flexible benefit, but it can function as a tool that reduces the employer's holiday-pay liability if fewer days are taken and none of it needs to be tracked or paid out beyond the statutory minimum.

What you're actually owed if you leave the job

This is where unlimited policies get contentious. When an employee leaves — whether by resignation, dismissal, or redundancy — UK law requires payment in lieu of any untaken statutory leave for the current leave year, calculated using normal weekly pay. Under a fixed allowance, this is straightforward: count the days remaining out of, say, 30, pro-rate for the point in the leave year, and pay accordingly. Under an unlimited policy, there's no fixed number to count down from, so employers will typically only recognise the statutory 28-day floor as the enforceable entitlement for payout purposes, arguing that any additional days taken beyond that were a discretionary benefit rather than an accrued right.

Worked example 2: Payment in lieu on redundancy

Fatima is made redundant on 30 September, exactly halfway through her company's leave year (which runs January to December). Her employer uses an unlimited holiday policy. By the point of redundancy, Fatima's pro-rata statutory entitlement for the year is 14 days (half of 28 days), and she has only taken 8 days of leave so far. She is owed payment in lieu of 6 untaken statutory days at her normal weekly pay rate. If Fatima earns £2,800/month, her weekly pay is roughly £646 (£2,800 x 12 / 52), so one day's holiday pay is approximately £129.20 (£646 / 5), meaning her payment in lieu for the 6 outstanding days comes to around £775. She should also check her overall redundancy position with

, since statutory redundancy pay and holiday payment in lieu are calculated and paid separately.

Worked example 3: Part-time pro-rata under an unlimited policy

Tom works 3 days a week under an employer with an "unlimited" holiday policy. His statutory minimum is pro-rated: 5.6 weeks x 3 days = 16.8 days per year, rounded up in practice to 17 days by most payroll systems. Even though his contract says "unlimited," if he leaves the company having taken only 10 of those days by the time his leave year is 70% through, he'd be owed payment in lieu for the shortfall against his pro-rata statutory floor of roughly 11.76 days (16.8 x 0.7), not against some open-ended figure. Tom can confirm his exact pro-rata entitlement using

alongside to combine his part-time pay and leave calculations.

Pros and cons compared with a fixed allowance

For employees weighing up a job offer with an unlimited holiday policy against one with a generous fixed allowance, the trade-offs are fairly consistent:

Advantages of unlimited holiday:

• Flexibility for senior or autonomous roles where output matters more than hours logged.
• No pressure to "use it or lose it" before a specific leave-year cutoff.
• Can support genuinely generous time off in strong, well-managed team cultures.

Disadvantages of unlimited holiday:

• No guaranteed number beyond the statutory 28-day floor, so ambiguity around what's "normal" to take.
• Manager discretion means requests can still be refused, undermining the "unlimited" branding.
• Weaker payout position on leaving the company, since only the statutory floor is clearly enforceable.
• Evidence suggests average days taken can be lower than under fixed allowances, effectively reducing total leave for some employees.

Advantages of a fixed allowance (e.g. 25-33 days):

• Clear, contractually trackable number that's easy to plan holidays around.
• Straightforward, predictable payment-in-lieu calculation on leaving.
• Removes ambiguity about how much time off is "acceptable" to take.

If you're comparing job offers, it's worth modelling your total take-home position, including the value of guaranteed leave, using

alongside your holiday entitlement figures, since a slightly lower salary with a clear, generous fixed allowance can sometimes be worth more in practice than a headline "unlimited" policy with weaker guarantees. Whatever the label on the policy, remember: 5.6 weeks (28 days pro-rata for full-time staff) is the legal floor no employer can take away, and that's the number worth holding onto when negotiating or planning your leave.
