Managing annual leave properly is one of those workplace tasks that looks simple until something goes wrong. A misplaced request, an unclear carry-over rule, or a poorly worded refusal can quickly turn into a grievance or a tribunal claim. Having the right paperwork in place gives both sides a clear record of what was asked, what was agreed, and why. This page walks through the main forms and letters that UK businesses tend to use when handling holiday entitlement: the annual leave request form, carry-over agreements, letters refusing leave, and letters designating holiday where a worker has not used their full allowance. I have written it for small and mid-sized employers who want to get the basics right, and for employees who want to understand what their employer should be doing. The aim is clarity, not jargon.

What this document is

Holiday entitlement forms are the written records that sit behind how a business administers statutory and contractual annual leave. Under the Working Time Regulations 1998, most workers in the UK are entitled to 5.6 weeks of paid annual leave each year, which works out at 28 days for a full-time worker (inclusive of bank holidays, unless the contract says otherwise).

Employers are free to offer more, and many do. The forms themselves are not legally prescribed, there is no official government template you must use, but having consistent paperwork helps you apply the rules fairly and defend your decisions if they are questioned.

The main documents fall into four categories: forms employees complete to request leave, agreements that set out how unused leave is carried into the next holiday year, letters refusing a request where the business genuinely cannot accommodate it, and notices requiring a worker to take leave on specific dates. Each serves a different purpose but they all rest on the same foundation of written notice, reasonable timing, and clear reasons.

How to use this document

  1. Set your holiday year and entitlement clearly. Before any form can work properly, your contract or staff handbook needs to state when the holiday year runs, how much leave each worker gets, and whether bank holidays are included. Without this, disputes about accrual and carry-over become much harder to resolve.
  2. Use a standard annual leave request form. Ask employees to submit requests in writing (paper or digital) showing their name, role, the dates requested, total days involved, and any notes relevant to the absence. A consistent format makes approvals faster and gives you a dated record if timing is ever challenged.
  3. Respond within a reasonable timeframe. The Working Time Regulations require employers to give at least as much notice refusing leave as the length of the leave requested. Approve or decline in writing, keep a copy, and if you are declining, explain the operational reason and offer alternative dates where possible.
  4. Document carry-over arrangements. If an employee wants to carry unused days into the next year, record the number of days, the reason (for example long-term sickness or parental leave), and the deadline by which they must be taken. UK case law and COVID-era rules have shifted the position on carry-over, so keep your wording up to date.
  5. Issue designated leave notices when needed. Where a worker has not booked enough of their entitlement and the year is ending, you can require them to take leave on specified dates by giving written notice of at least twice the length of the leave being designated. Put it in writing and keep it on file.

Common questions

Q How much annual leave are UK workers entitled to?
Most workers in the UK are entitled to 5.6 weeks of paid annual leave per year under the Working Time Regulations 1998. For a full-time employee working five days a week, that is 28 days, and employers can choose whether to include the eight bank holidays within this figure or give them on top. Part-time workers get a pro-rated amount based on the days they work.
Q Can an employer refuse a holiday request?
Yes, an employer can refuse a leave request for genuine operational reasons, such as staffing shortages or busy trading periods. The refusal must be given in writing and the notice period must be at least as long as the leave being declined. So if an employee asks for a two-week break, the employer needs to respond at least two weeks before the start date.
Q Can unused holiday be carried over into the next year?
It depends on the contract and the circumstances. The statutory minimum of four weeks generally has to be taken within the holiday year, but the additional 1.6 weeks can be carried over by agreement. Where an employee could not take leave due to sickness or family leave, more generous carry-over rules may apply. Always record the agreement in writing.
Q Can an employer force an employee to take annual leave?
Yes, an employer can require a worker to take leave on specific dates, for example during a Christmas shutdown or to use up unused entitlement before year end. Written notice must be given of at least twice the length of the leave being designated. So to require a worker to take five days off, at least ten days' notice is needed.
Q Does annual leave need to be paid at the normal rate of pay?
Yes. Workers should receive their normal weekly pay during annual leave. For those with variable hours or commission, recent case law means holiday pay should reflect average earnings over a reference period (currently 52 weeks). Paying only basic salary when a worker regularly earns overtime or commission can lead to unlawful deduction claims.
Q What happens to unused holiday when someone leaves the job?
When employment ends, the employee is entitled to be paid for any accrued but untaken statutory leave up to their leaving date. If they have taken more leave than they had accrued, the contract may allow the employer to recover the overpayment from their final pay, but only if there is a clear written clause permitting this.
Q Do holiday entitlement forms need to follow a legal template?
No, there is no prescribed government form for requesting, refusing, or designating annual leave. What matters is that the process is clear, applied consistently, and documented. Having standard forms helps, but the legal test is whether the rules in the Working Time Regulations and the employment contract have been followed properly.
