How to Manage TOIL in the UK: A Practical Employer Guide (2026)

What Is TOIL and Why Does It Matter?

Time Off In Lieu (TOIL) is an arrangement where employees who work beyond their contracted hours receive paid time off rather than extra pay. For example, an employee who stays two hours late completes a project might earn two hours (or more, depending on the agreed rate) to take off another day.

TOIL is popular in the UK because it defers the cost of overtime — employees get rewarded without an immediate payroll hit, and they often prefer the flexibility of extra time off over extra pay. But poorly managed TOIL creates legal risk, accounting uncertainty, and staff frustration. This guide covers everything you need to manage TOIL properly.

Is TOIL a Legal Requirement in the UK?

No — TOIL is not a statutory right in the UK. There is no legal requirement for employers to offer TOIL. However, if you agree to TOIL with an employee (whether verbally, in writing, or through a workplace policy), that agreement becomes contractually binding.

The key legal requirement that touches TOIL is the Working Time Regulations 1998 (WTR). The WTR sets a maximum average working week of 48 hours (unless an employee opts out) and minimum rest periods. TOIL that isn't taken promptly can result in employees exceeding WTR limits — creating legal exposure for employers.

See our complete TOIL guide for UK employers and the Working Time Regulations guide for detailed legal context.

Setting Your TOIL Accrual Rate

The accrual rate determines how much TOIL an employee earns per hour of overtime worked. Common UK rates are:

• 1:1 (hour for hour) — The most common approach. One hour of overtime earns one hour of TOIL. Simple to track and easy for employees to understand.
• 1.5:1 (time and a half) — One hour of overtime earns 1.5 hours of TOIL. Often applied to evening, weekend, or bank holiday work.
• 2:1 (double time) — One hour earns two hours of TOIL. Typically reserved for bank holidays or emergency out-of-hours responses.

You can use different rates for different circumstances — for example, 1:1 for weekday overtime and 1.5:1 for weekend work. Whatever you agree, document it clearly in your TOIL policy. Use our TOIL calculator to work out accrual under any rate.

Writing a TOIL Policy

A clear written TOIL policy prevents disputes and ensures consistency. Your policy should cover:

• Eligibility — which employees can accrue TOIL (e.g., salaried only, or all employees)
• Authorisation — whether overtime must be pre-approved or can be self-reported
• Accrual rate — how much TOIL is earned per hour of overtime, and whether different rates apply in different circumstances
• Maximum accrual — a cap on how many TOIL hours can be banked at any time (e.g., maximum 2 days or 16 hours)
• How to request TOIL leave — the same process as annual leave, or a separate process
• Expiry — when TOIL expires if not taken (e.g., must be used within 3 months of accrual, or within the current leave year)
• Pay-out on termination — whether unused TOIL is paid out when an employee leaves

Managing TOIL Authorisation

One of the most common mistakes is allowing employees to accrue unlimited unauthorised TOIL. Without a clear authorisation process, employees may claim TOIL for hours worked that weren't agreed in advance — creating disputes and inflated balances.

Best practice is to require manager pre-approval for any overtime that will be compensated by TOIL. The employee should record the overtime, the manager should confirm it was pre-authorised (or approve it retrospectively), and the TOIL balance updates automatically.

TimeTally's TOIL management software builds this workflow in — employees submit timesheets with overtime flagged, managers approve, and TOIL accrues automatically. No spreadsheets, no disputes.

Setting Carryover Limits and Expiry Rules

TOIL that is never taken becomes a hidden liability. An employee sitting on 40 hours of TOIL who then leaves the business — or takes all their TOIL in the same week — can cause serious operational and cash-flow problems.

Prevent this with carryover limits and expiry rules:

• Maximum balance cap — set a limit on how much TOIL can be accrued. Once an employee hits the cap, no further TOIL accrues until some is used.
• Expiry date — TOIL not taken within X months expires. This keeps balances manageable and incentivises employees to actually take rest.
• Leave year reset — some employers clear TOIL balances at the end of each leave year (with or without a pay-out for the remainder).

Record Keeping for TOIL

The Working Time Regulations require employers to keep adequate records to show that the 48-hour average working week limit is being complied with. For employees on TOIL arrangements, this means keeping records of overtime worked as well as TOIL taken.

At minimum, you should record:

• The date and number of hours of overtime worked
• Who authorised the overtime
• The TOIL balance accrued (running total)
• Dates and hours of TOIL leave taken
• Remaining TOIL balance

This is difficult to do reliably on spreadsheets — especially for teams where overtime is frequent. Purpose-built TOIL tracking software automates this entirely.

Common TOIL Management Mistakes

1. No written policy

If TOIL is managed informally, disputes about balances and entitlements are almost inevitable. Always document your TOIL arrangements in writing.

2. Unlimited accrual

Without caps, TOIL balances grow unchecked. A team of 10 employees each sitting on 2 weeks of TOIL represents a significant liability — both operationally and financially.

3. Confusing TOIL with annual leave

TOIL and annual leave are separate entitlements. Using annual leave to cover outstanding TOIL (or vice versa) creates accounting confusion and can lead to employees inadvertently falling below their statutory annual leave entitlement.

4. Not tracking in real time

Monthly spreadsheet updates mean balances are often wrong. Employees lose confidence in the system, and managers make leave approval decisions based on stale data. Real-time tracking via software eliminates this problem.

5. No expiry rules

TOIL without expiry becomes an open-ended liability. Set expiry dates — employees are motivated to take rest, and your balance sheet stays accurate.

TOIL on Termination

If an employee leaves with unused TOIL, are you required to pay it out? There is no statutory requirement to pay out unused TOIL on termination — unlike statutory annual leave, which must always be paid out. However, if your TOIL policy or employment contract states that unused TOIL will be paid out, you are contractually obliged to honour this.

If your policy is silent on termination pay-out, you have flexibility — but be consistent to avoid discrimination claims. It's best to address this explicitly in your policy.

TOIL and the Employment Rights Act 2026

The Employment Rights Act 2026 introduces new provisions that affect flexible and overtime working in the UK. While TOIL itself isn't directly legislated, the Act strengthens employee rights around predictable hours and flexible working requests — both of which intersect with TOIL practices.

See our guide to TOIL under the Employment Rights Act 2026 for the latest guidance.

Using Software to Manage TOIL
