Time off in lieu (TOIL): how it works
TL;DR, the essentials
- Time off in lieu (TOIL) is paid time off that an employee earns by working extra hours, taken as rest later instead of being paid overtime.
- It is usually set by company policy or the employment contract, not by a single universal law.
- The most common rule is hour for hour: one extra hour worked earns one hour off, though some employers apply a higher rate.
- A good policy sets how TOIL is approved, recorded and used before it expires.
- Working time, pay and leave rules vary by country, so always check your local law and your own contract.
Work late to hit a deadline, then take an afternoon off the following week instead of extra pay. That trade is the whole idea behind time off in lieu. The concept is simple, but the details, how it is earned, calculated, approved and when it expires, trip up plenty of managers and employees. Here is how TOIL works, how to calculate it, how it compares with overtime pay and what belongs in a clear policy. The rules below explain the general principle with UK context where useful; employment law and pay differ by country, so treat this as background information rather than personalised legal advice.
What is time off in lieu?
Time off in lieu, often shortened to TOIL, is paid time off that an employee builds up by working beyond their normal contracted hours. Instead of being paid for those extra hours, the employee takes an equivalent amount of paid rest at a later date. The phrase “in lieu” simply means “instead of”, here, rest instead of overtime pay.
The logic is one of compensation, and it plays out in three steps.
A normal working baseline
Every employee has contracted hours, for example 37.5 or 40 hours a week, that define what counts as normal working time.
Extra hours are worked
When someone works beyond that baseline, to cover a deadline, an event or a busy period, those hours are recorded.
Rest is given back
Instead of overtime pay, the employee banks the extra time and takes it later as paid time off, subject to approval.
Good to know
In most countries there is no single statute that creates a universal right to TOIL. It exists because the employer and employee agree to it, through the contract, a collective agreement or a written policy. That is why the exact rules can differ from one company to the next.
How does TOIL work in practice?
TOIL works like a small time bank. Extra hours worked are credited to a balance, and paid time off is debited from it when the employee takes rest. Because it is agreed rather than imposed by law, the mechanics depend on the policy, but the pattern is almost always the same.
- Approval first. Extra hours usually only count as TOIL if they were agreed or authorised in advance by a manager, not simply because someone chose to stay late.
- The time is recorded. The banked hours are logged, ideally in a timesheet or HR system, so both sides can see the running balance.
- Time off is booked. The employee requests time off against the balance, much like booking annual leave, subject to business needs.
- A deadline applies. Many policies require TOIL to be used within a set window, for example the same month or quarter, or it is lost.
Watch out
TOIL is separate from annual leave and from statutory holiday entitlement. In the UK, for example, workers are entitled to a minimum amount of paid holiday under the Working Time Regulations; TOIL sits on top of that, it does not replace it. Check how your policy treats the two so banked hours are not quietly swallowed into your holiday balance.
Quick quiz
What does an employee receive when they take time off in lieu?
How is time off in lieu calculated?
This is where most confusion starts, because there is no single legal formula. The rate is whatever the policy or contract sets. Two approaches are common, shown here as indicative examples rather than fixed rules.
- Hour for hour is the most widespread. Each extra hour worked earns exactly one hour of time off. Work three extra hours, bank three hours off. It is simple and easy to track.
- Enhanced or premium TOIL mirrors overtime multipliers. Some employers give more time off for unsociable hours, for example 1.5 hours of TOIL for each hour worked on a weekend or public holiday. This is a policy choice, not a legal default.
A short worked example makes it concrete. Suppose an employee on a 37.5 hour week works 43 hours one week to finish a project, with the extra time authorised in advance. On an hour for hour basis they bank 5.5 hours of TOIL, which they might later take as a half day plus a short early finish, once approved. If the policy applied a 1.5 rate for those hours, the same 5.5 extra hours would instead credit 8.25 hours. The figures depend entirely on the agreed rate.
Smart move
Write the calculation rate into the policy in plain numbers and give a worked example. Ambiguity over “an hour for an hour” versus enhanced rates is one of the most common sources of TOIL disputes. When in doubt, confirm the rate with your HR or payroll team before banking hours.

TOIL or overtime pay: what is the difference?
TOIL and overtime pay answer the same question, how do we compensate extra hours, but they settle it in different currencies. Overtime pays money; TOIL pays time. Which one applies depends on the contract and, in some roles, on what the employee prefers.
The trade offs are worth weighing on both sides.
- For the employee. TOIL protects work life balance and rest, but it does not boost the payslip. Overtime pay adds income, sometimes at a premium rate, but does not give back time.
- For the employer. TOIL avoids extra wage cost and can smooth workload across quieter periods, but it needs careful tracking so balances do not pile up. Overtime is simpler to administer but adds to the wage bill.
Overtime pays extra hours in money; time off in lieu pays them back in rest. Same effort, two very different settlements.The MiisterSoftware team, HR vocabulary note.
One important caveat: whether an employer can offer TOIL instead of paid overtime, and at what rate, depends on the contract and on local employment law. Some jurisdictions and collective agreements set minimum overtime pay that cannot simply be swapped for time off without agreement. Always check the contract and your local rules before assuming one can replace the other.
What should a time off in lieu policy cover?
Because TOIL is created by agreement, a clear written policy is what keeps it fair and workable. The strongest policies leave little room for interpretation. At a minimum, a TOIL policy should spell out:
- Who is eligible and which hours qualify, for example only pre approved extra hours beyond contracted time.
- The accrual rate, hour for hour or an enhanced rate for unsociable hours, with a worked example.
- How TOIL is requested and approved, and how it is recorded, so balances are transparent.
- An expiry window, the period within which banked time must be taken before it lapses.
- What happens on leaving, whether unused TOIL is paid out or lost when someone exits the business.
Good to know
An expiry rule is what stops TOIL turning into an ever growing liability. If banked hours have no deadline, they accumulate, and disputes over old balances become likely. A common approach is to require TOIL to be used within a defined period, with any exceptions agreed in writing.
Time off in lieu and the law
TOIL itself is rarely a statutory right, but it interacts with rules that are set by law, and those rules vary by country. Two areas matter most.
First, working time limits. Many countries cap average weekly working hours and set minimum daily and weekly rest. In the UK, the Working Time Regulations limit average weekly working time and require rest breaks, unless a valid opt out or exception applies. TOIL should never be used to push someone beyond the working time protections that apply where they work.
Second, statutory holiday and pay. Paid holiday entitlement, along with statutory schemes such as Statutory Sick Pay and Statutory Maternity Pay in the UK, is set by law and sits apart from TOIL. Banked TOIL does not reduce those entitlements. The exact minimums, amounts and eligibility rules differ from country to country, so the safest reference is always your local law and your own contract.
Watch out
The figures, thresholds and entitlements mentioned here are illustrative of the UK context and change over time. They are not a substitute for advice on your specific situation. Confirm the current rules with your HR or payroll team, or with the official guidance for your country, before acting on them.

Frequently asked questions
What is time off in lieu (TOIL)?
Time off in lieu, or TOIL, is paid time off that an employee earns by working extra hours beyond their contracted time. Instead of being paid overtime, the employee takes an equivalent amount of paid rest later. It is usually set by company policy or the employment contract rather than by a single universal law, and the rules can vary by country and employer.
How is TOIL calculated?
There is no single legal formula; the rate is set by the policy or contract. The most common approach is hour for hour, where each extra hour worked earns one hour of time off. Some employers apply an enhanced rate, for example 1.5 hours of TOIL for each hour worked on a weekend or public holiday. Always check your own policy for the exact rate.
Is TOIL the same as overtime pay?
No. Both compensate extra hours, but overtime pays money while TOIL gives paid time off instead. Which one applies depends on the contract and, in some roles, on employee preference. Whether TOIL can replace paid overtime, and at what rate, depends on the contract and local employment law, so check both before assuming one can substitute for the other.
Does TOIL count as annual leave or holiday?
No. TOIL is separate from statutory holiday entitlement and from annual leave. It is time earned by working extra hours, and it sits on top of the paid holiday employees are entitled to by law. Banked TOIL should not reduce statutory leave or pay, though the exact rules differ by country, so check your local law and contract.
What happens to unused TOIL?
It depends on the policy. Many employers require TOIL to be used within a set window, such as the same month or quarter, after which it is lost unless an exception is agreed in writing. Some policies pay out or forfeit remaining TOIL when an employee leaves. Tracking the balance during the year avoids losing banked hours to an expiry deadline.
