Holiday Pay on Termination of Employment in the UK: Employer Rules

Ending an employment relationship is never just about the “last day”. For most small businesses, the tricky part is getting the final pay right - especially when unused annual leave is involved.

If you’re dealing with a resignation, redundancy or dismissal, you’ll usually need to calculate the holiday pay on termination of employment in the UK that the rules require, include it in the employee’s final wages, and pay it at the right time. Get it wrong, and you can quickly find yourself facing disputes, grievances, or even Employment Tribunal claims.

In this guide, we’ll break down what you need to pay, how to calculate it (including common pitfalls for irregular hours and commission), and when it should be paid - all from an employer’s perspective.

What Does “Holiday Pay On Termination Of Employment” Mean For Employers?

When an employee leaves your business, they may have:

• Untaken statutory annual leave (the minimum leave required by law); and/or
• Untaken contractual leave (any extra leave you provide on top of the statutory minimum).

If they’ve accrued leave but haven’t taken it by their termination date, you’ll generally need to pay them for it. This is often called payment in lieu of holiday.

In the UK, annual leave entitlements and pay are mainly governed by the Working Time Regulations 1998. In simple terms, these rules give most workers a legal entitlement to paid annual leave and require employers to pay for leave that has been accrued but not taken when employment ends.

There’s a second piece to this as well: if the employee has taken more leave than they’ve accrued by the time they leave, you might be able to deduct money from their final wages - but only if you have the right contractual wording and follow payroll deduction rules (more on that below).

From a practical standpoint, getting holiday pay on termination right means you should be able to answer three questions confidently:

• How much leave has the employee accrued up to their last day?
• How much leave have they already taken?
• What is the correct “week’s pay” rate for that employee?

When Do You Have To Pay Outstanding Holiday Pay In The UK?

Most small businesses pay holiday pay owed on termination in the employee’s final pay run. In many cases, that will be:

• on the employee’s last working day (if you do off-cycle payments); or
• on the next normal payroll date following termination.

There isn’t a single “one size fits all” deadline stated as a specific number of days for every scenario, but the key employer obligation is this: final wages (including any accrued but untaken holiday) should be paid in line with the employment contract - typically on the next normal pay date - and without unreasonable delay. If you fail to pay holiday pay owed, it can be treated as unlawful deduction from wages, which is a common basis for Employment Tribunal claims.

So, as a risk-management approach, it’s best to:

• calculate outstanding holiday pay before the last day where possible;
• include it clearly on the final payslip; and
• pay it on the final payroll date (or earlier).

If you’re also paying notice pay (or PILON), redundancy pay, commission, or bonus amounts, it’s even more important that your final pay calculation is documented and double-checked.

One more thing: if you’re changing the employee’s final working arrangements - for example asking them to use remaining leave during notice - make sure your approach aligns with your contract and policies. Many businesses set this out in their Employment Contract and/or staff handbook.

How Do You Calculate Holiday Pay On Termination Of Employment UK Rules Apply?

This is where most disputes start - not because employers are trying to underpay, but because holiday calculations can be deceptively technical.

To calculate outstanding holiday pay, you generally follow these steps:

1) Confirm The Employee’s Leave Entitlement

Statutory holiday entitlement for most workers is 5.6 weeks per leave year (that’s 28 days for someone who works 5 days a week), which can include bank holidays if your contract says so.

If your contracts say holiday is “inclusive of bank holidays”, be clear what that means in practice and keep it consistent across payroll and HR records. If you need a refresher on wording and common misunderstandings, “inclusive” clauses are often discussed in contexts like bank holiday wording.

Also check whether you offer additional contractual leave (e.g. 30 days total). If you do, your contract should explain how contractual leave is treated on termination.

2) Work Out How Much Leave Has Accrued Up To Termination

Holiday usually accrues over time across the leave year. Many businesses do a simple pro-rata calculation based on:

• the employee’s annual entitlement; and
• the proportion of the leave year worked up to the termination date.

Example: An employee is entitled to 28 days per year and leaves exactly 6 months into the leave year. Roughly speaking, they accrue about 14 days by that point (subject to how your leave year is defined and how you handle rounding).

Be careful if:

• your leave year does not match the calendar year;
• the employee changed hours mid-year; or
• they moved from full-time to part-time (or vice versa).

3) Subtract Leave Already Taken

Once you know accrued leave, subtract the leave the employee has actually taken (and been paid for) in that leave year.

If the result is positive, you’ll usually need to pay it out.

If the result is negative (they’ve overtaken their leave), you may be able to make a deduction - but only if your contract allows it and you comply with wage deduction rules. If you don’t have a clear contractual clause, it’s often safer to treat this as a business cost than risk an unlawful deduction claim.

4) Calculate The “Week’s Pay” (This Is Often The Real Problem)

Holiday pay isn’t always the same as basic pay - especially if the employee’s “normal pay” includes variable elements.

Depending on the working pattern, holiday pay calculations may need to take into account things like:

• regular overtime;
• commission that is intrinsically linked to the role;
• certain allowances that are paid regularly.

For employees with normal working hours and fixed salary, the calculation is usually straightforward.

For those with irregular hours or variable pay, you may need to use an averaging approach over a reference period. This can be particularly important for hospitality, retail, care, trades, and other small businesses where hours vary week to week.

If you’re not confident your payroll approach reflects “normal remuneration”, it’s worth getting advice - because underpaying holiday on termination is one of those issues that can look small on paper but quickly escalates once a dispute starts.

5) Put It On The Payslip And Keep A Paper Trail

It’s good practice to itemise final payments so the employee can see:

• basic pay to last day worked;
• notice pay (if applicable);
• holiday pay (paid in lieu) - showing days/hours and rate;
• any authorised deductions.

This is also a helpful internal control for your business if questions are raised later.

Common Employer Scenarios (And The Mistakes That Cause Disputes)

Holiday pay on termination of employment in the UK comes up in lots of “real world” situations. Here are the ones we see most often for small businesses.

Resignation With Untaken Leave During Notice

An employee resigns, gives notice, and has 6 days of leave remaining. You generally have two options (depending on the contract and operational needs):

• Require them to take leave during notice (if you give proper notice and can accommodate it operationally); or
• Pay it out on termination as part of final pay.

If you’re managing notice periods and exit processes, it helps to have consistent written processes and clear resignation communications. Even something as simple as a written resignation can avoid misunderstandings later - many businesses use a standard approach similar to a resignation letter format as part of good HR hygiene.

Dismissal Or Redundancy (Including Garden Leave)

When employment ends due to redundancy or dismissal, holiday pay still needs to be handled correctly. Don’t assume that because an employee is leaving on “bad terms” you can deprioritise the payroll side - that’s exactly when disputes are most likely.

If the employee is placed on garden leave, their holiday may continue to accrue during the notice period, depending on how the termination is structured and what your contract says.

Part-Time Staff And Bank Holidays

Bank holidays are a common flashpoint, especially for part-time workers whose “usual” working days don’t fall on bank holidays.

Your contract needs to be clear, and your payroll/HR teams need to apply it consistently. If you’re unsure about handling bank holiday entitlements fairly, it can help to review issues like non-working days and bank holidays to avoid accidental underpayment or unfairness.

Overtaken Holiday And Deductions From Final Pay

This is the scenario where an employee takes more leave than they’ve accrued, then leaves mid-year. Employers often ask: “Can we just deduct it from their final wages?”

Sometimes you can - but only if:

• your employment contract (or a separate written agreement) clearly allows the deduction; and
• you apply deductions lawfully and transparently.

If you don’t have a deduction clause, making the deduction can trigger an unlawful deduction claim.

Irregular Hours, Zero-Hours, Or Variable Pay Workers

In small businesses, this is where admin gets tough. If a worker’s hours vary, you need to keep accurate records of:

• hours worked;
• leave taken (in hours, not just “days”); and
• the relevant pay reference data you use for holiday pay.

If you’re not already tracking this, it’s worth tightening up your processes now. It’s much harder to fix after someone has left and disputes your calculation.

How To Protect Your Business: Policies, Contracts, And A Simple Process

The best way to avoid holiday pay disputes is to treat annual leave like a compliance process, not just an admin task.

Here’s a practical employer checklist you can implement quickly.

Set Clear Rules In Your Employment Contract

Your contract should clearly cover:

• the leave year dates;
• holiday entitlement (and whether it includes bank holidays);
• how leave accrues and how it should be requested/approved;
• whether you can require employees to take leave during notice; and
• whether you can deduct overtaken leave from final pay.

If your contracts are unclear or inconsistent, that’s when “we thought it meant…” disputes happen. Having a properly drafted Employment Contract is often the simplest way to reduce exit-related payroll risk.

Have A Written Holiday Approval And Recordkeeping System

You don’t need expensive software. But you do need:

• a single source of truth for leave balances (avoid multiple spreadsheets across managers);
• written approval records; and
• a consistent approach for part-time and irregular workers.

Be Careful When You “Dictate” Leave

Some businesses require staff to take leave at certain times (for example, during a Christmas shutdown). That can be lawful, but it needs to be handled properly and fairly.

If this is part of your operating model, it’s worth understanding the rules around dictating holidays so your approach doesn’t accidentally create employee relations issues (or claims).

Check Your Termination Workflow Before The Last Day

When you receive a resignation or confirm a dismissal/redundancy, build a short “leaver checklist” that includes:

• termination date confirmation in writing;
• holiday balance calculation (including any approved-but-not-taken leave);
• payroll sign-off and payslip breakdown;
• return of company property; and
• reminders about confidentiality and post-termination obligations.

This is also a good time to check whether the employee’s working time and leave records are in order under the Working Time Regulations approach your business applies.

Key Takeaways

• In most cases, the holiday pay on termination of employment in the UK rules mean you must pay employees for untaken accrued annual leave when their employment ends.
• You should usually pay outstanding holiday pay in the final pay run (or earlier) in line with the contract and normal payroll date, and clearly itemise it on the final payslip to reduce disputes.
• Holiday pay calculations involve more than just “basic salary” if the employee has variable pay elements like regular overtime or commission.
• If an employee has taken more leave than they’ve accrued, you can only deduct it from final pay if you have clear contractual authority and follow lawful deduction rules.
• Clear contracts, consistent holiday records, and a simple leaver checklist are often the difference between a smooth exit and a painful dispute.
• If you’re unsure about calculations (especially for irregular hours), getting tailored advice early can save your business time, cost and risk later.
