A Guide to Days Off in Lieu (TOIL)

Posted by Robin on 27 Sep, 2025 in Guides

When someone talks about days off in lieu, what they’re really describing is a system where you get paid time off for working extra hours, rather than getting a bump in your pay packet for overtime.
You can think of it like a ‘time bank’. You work a few extra hours here and there, deposit them into your bank, and then withdraw them later as leave when you need a break. It’s a simple but effective way to add a bit of flexibility into the working week.

Getting to Grips with the Basics of TOIL

At its heart, time off in lieu (often shortened to TOIL) is a straightforward swap. Instead of getting paid more for hours worked beyond your contract, you get the same amount of time back to use as paid leave later on. It’s a common setup in plenty of UK workplaces and offers a flexible solution for managing workloads during busy spells without burning everyone out.
Let's say your contract is for 40 hours a week, but a big project deadline means you end up working 45 hours one week. Those extra five hours don't just disappear. With a TOIL system, they’re added to your time bank. You can then take that five-hour block of paid leave on another day—maybe clocking off early on a Friday or enjoying a late start on a Monday.

So, How Does a TOIL System Actually Work?

This kind of arrangement is quite different from your standard annual leave. Annual leave is a fixed pot of days you get every year, whereas days off in lieu are earned directly through putting in extra work. Getting this distinction right is crucial for both employees and managers. When you’re clear on the different types of leave, it makes for better policies and fairer conversations.
Here's a quick rundown of what makes TOIL unique:
  • You Earn It, It’s Not a Given: TOIL is built up based on the actual extra hours you work. It’s not a flat allowance handed out at the start of the year.
  • Flexible to Use: Employees can often use their accrued time in smaller chunks, like a few hours here and there, instead of having to take a full day off.
  • A Smart Move for Employers: It lets businesses handle busy periods without racking up extra payroll costs from overtime pay.
A well-managed TOIL system strikes a healthy balance between business needs and employee wellbeing. It's a way of rewarding that extra effort with something incredibly valuable: time. For many people, a shorter working week now and then is worth more than the extra cash.
Let's take a look at how days off in lieu stack up against other types of time off.

TOIL vs Overtime Pay vs Annual Leave

To make the differences crystal clear, here’s a quick comparison of the key features of time off in lieu, standard overtime payment, and your annual leave entitlement.

Attribute Days Off in Lieu (TOIL) Overtime Pay Annual Leave | Compensation  | Time off  | Financial payment  | Time off
| How it's Acquired  | Earned by working extra hours  | Earned by working extra hours  | Fixed annual entitlement
| Flexibility  | High (can often be taken in hours)  | N/A (it's a payment)  | Moderate (usually taken in half/full days)
| Cost to Employer  | No direct payroll cost  | Increased payroll cost  | Pre-budgeted payroll cost
This table shows that while all three relate to employee compensation and time off, they serve very different purposes and operate under different rules. Understanding this helps everyone stay on the same page.
This visual really drives home the on-demand and variable nature of TOIL, setting it apart from the more structured and predictable framework we see with statutory holidays.

The History of Time Off in the UK

While the idea of getting days off in lieu feels like a modern perk for flexible working, its origins are actually buried deep in British history. Long before we had employment contracts and HR departments, the rhythm of work was dictated by the seasons and religious festivals, creating a natural patchwork of unofficial holidays.
Then the Industrial Revolution changed everything.
The relentless pace of factories and mills put productivity above all else. This shift forged a workforce that was often exhausted and chronically overworked, sparking a long and difficult negotiation between the demands of labour and the need for rest. It became clear that some form of structured downtime was essential.

From Unofficial Breaks to Formal Holidays

Early attempts to solve this were often community-led. A famous example is the 'Wakes Week', a tradition where entire factory towns would shut down for a week each year, giving everyone a collective holiday. You could think of it as an early, informal version of mass annual leave.
But a more organised approach was desperately needed. The discussion around official time off started gathering steam, eventually leading to a landmark piece of legislation. Before things were formalised, public offices enjoyed up to 40 holidays a year, a number that was drastically slashed to just four by 1834. The real groundwork for our modern system came with the Bank Holidays Act of 1871, which established the first official national bank holidays. You can discover more insights about the evolution of UK holidays.
This Act was a pivotal moment. It was the first time the state officially recognised that workers needed guaranteed, paid rest days. It also created the very problem that time off in lieu would later solve: what happens when someone has to work on one of these new public holidays?

The Birth of Compensatory Time Off

With bank holidays officially on the calendar, a new challenge appeared. Essential services still had to run, and certain industries simply couldn't grind to a halt. This is where the concept of compensatory time off—the direct ancestor of today's days off in lieu—really started to take shape.
If someone was required to be on duty during a bank holiday, it only seemed fair to offer them another day off as a substitute. This simple, practical solution allowed businesses to keep operating while still honouring an employee's right to rest.
This core principle of swapping a worked holiday for a future day off is exactly how TOIL functions today, making it a direct descendant of the UK's industrial past.

Understanding Your Legal Rights

When it comes to days off in lieu, the legal side of things is a major source of confusion. A lot of people believe there’s an automatic right to get TOIL for slogging through extra hours or working a bank holiday, but that’s simply not the case in the UK.
Your entitlement almost always boils down to one single, crucial document: your employment contract. Think of it as the ultimate rulebook for your job. If a TOIL policy isn't clearly written down in your contract or a company handbook, your employer is under no legal obligation to offer it. Simple as that.
This makes the contract the single source of truth for everyone involved, helping to head off disputes before they even start by setting clear expectations from day one.

The Role of Your Employment Contract

Your contract is the first place you should look. It needs to state exactly how overtime is handled. Does the company pay for the extra hours you put in, or do they offer time off in lieu as compensation? A well-written contract leaves no room for guesswork.
If you’re an employee, grab your contract and look for clauses covering:
  • Overtime: How are hours worked beyond your standard agreement compensated?
  • Bank Holidays: Does it mention getting paid or taking TOIL for working on these days?
  • Working Hours: This section defines your normal work week and should detail any policies for extra work.
For employers, spelling out your TOIL policy in every contract is non-negotiable. It protects the business from messy misunderstandings and guarantees that everyone on the team is treated fairly and consistently. To keep everything above board, it's also smart to understand the essential small business legal requirements that shape employment practices.

What About the Working Time Regulations?

While your contract is king, UK law does set some ground rules that indirectly affect TOIL. The Working Time Regulations 1998 are there to protect employees' health and safety by putting a cap on excessive hours.
These regulations mean you can't be forced to work more than 48 hours per week on average, unless you've willingly signed an opt-out agreement. This is a big deal. While the law doesn't force employers to offer TOIL, it absolutely cares about your total working hours and making sure you get enough rest. For instance, you’re legally entitled to 11 consecutive hours of rest in any 24-hour period.
TOIL can be a brilliant tool for making sure you stay on the right side of these rest period rules. By letting an employee take back the time they've worked, you’re helping them get proper rest and avoid burnout, which is exactly what the law intends.
It's vital to see how your contractual rights and statutory limits work together. Speaking of statutory rules, getting the basics right is always a good idea. You can dive deeper with our complete guide to UK statutory holiday allowance to make sure you're clear on all types of leave.
Ultimately, the regulations focus on health and safety through rest, not on dictating how you should be compensated for extra work. That part comes right back to the agreement between you and your employer—your contract.

How to Create a Fair TOIL Policy

If your business offers days off in lieu, a formal, written policy isn’t just a nice-to-have—it's an absolute must. Without clear rules of the road, you’re paving the way for confusion, inconsistent treatment, and arguments down the line. A solid TOIL policy is your single source of truth for both managers and staff, making sure everyone is treated fairly.
Think of this policy as a practical, easy-to-follow guide that removes all the guesswork. It should map out the entire process, from getting extra hours approved and logged to how that hard-earned time off can actually be taken.

Laying the Foundation for Your Policy

First things first, you need to nail down the core principles of your system. A robust policy tackles the big questions from the very beginning. Ambiguity is the enemy here; any grey areas now will cause headaches later, so your primary goal is crystal-clear clarity.
Your policy must spell out exactly how days off in lieu are earned. Is it a simple hour-for-hour swap? Or will you offer a better rate for unsociable hours, like working a Sunday or a bank holiday? This is a crucial detail that directly shapes how your team will feel about the whole arrangement.
A fair TOIL policy is proactive, not reactive. It anticipates potential issues—like leave piling up or approval bottlenecks—and builds in simple, clear solutions before they become problems for the business.

Defining the Rules of Engagement

Once the basics are in place, it’s time to add the operational details that will make the policy work day-to-day. These rules are all about managing expectations and stopping the system from being taken for a ride.
You’ll want to build these essential components into your policy:
  • Approval Process: All overtime that earns TOIL must be signed off by a line manager before the work is done. This simple step stops people from racking up unauthorised hours and gives you crucial control over workloads and costs.
  • Recording Hours: You need a foolproof way of tracking those extra hours. Whether it’s a digital timesheet or a dedicated leave management system, the process has to be accurate, trustworthy, and easy for everyone to use.
  • Time Limits for Use: Setting an expiry date is standard practice for a reason. Most companies require TOIL to be used within three to six months of it being earned. This prevents staff from hoarding huge amounts of leave, which can quickly turn into an operational nightmare for scheduling.
Creating these rules is only half the battle; making them accessible is just as vital. To ensure your TOIL policy is clear and available to all employees, consider leveraging best practices for creating a robust internal knowledge base.

Structuring Your TOIL Document

Your written policy should be logically laid out and dead simple to navigate. Think of it as a user manual for your company’s approach to overtime. A clean structure helps everyone find what they need without having to ask.
To help you get started, we've outlined the essential components your policy needs to cover in the table below.

Essential Elements of a TOIL Policy

This table breaks down the key components every company's TOIL policy should include to ensure it's clear, fair, and effective for both employees and managers.

Policy Component Key Considerations Example Clause | Eligibility  | Define which roles, departments, or contract types are included. Is it for salaried staff only?  | "This TOIL policy applies to all full-time and part-time employees in non-senior management roles."
| Accrual Rates  | Specify the exact exchange rate. Is it 1:1, or enhanced for weekends/bank holidays?  | "Overtime worked Monday to Friday will accrue TOIL at a rate of 1:1. Overtime on weekends will accrue at 1.5:1."
| Approval Process  | Detail who approves overtime and how. Must it be in writing?  | "All overtime must be pre-approved in writing by your direct line manager via the HR portal before any work commences."
| Recording & Tracking  | How are hours logged and verified?  | "Employees must log all approved overtime hours in their Leavetrack timesheet by the end of the working week."
| Booking TOIL  | Explain the process for requesting time off. How much notice is needed?  | "TOIL days must be requested with a minimum of 7 days' notice through the standard leave booking system."
| Expiry Rules  | Set a clear time limit for using accrued TOIL.  | "All accrued TOIL must be used within 3 months of the date it was earned. Any unused TOIL will expire after this period."
| Leaving the Company  | State what happens to unused TOIL upon termination of employment. Is it paid out?  | "Unused TOIL will not be paid out upon termination of employment. Employees are expected to use any accrued leave before their final day."
By covering these key areas, your policy will provide the clarity and structure needed to manage time off in lieu effectively.
A good policy should cover these four key areas:
  1. Eligibility: Who is actually covered by the TOIL scheme? Be specific. It might apply to certain roles or departments but exclude others.
  2. Accrual Rates: Clearly state the rate at which TOIL is earned (e.g., one hour of TOIL for every one hour of overtime). No ambiguity!
  3. Booking Process: Outline the step-by-step process for requesting and getting approval for those hard-earned days off in lieu.
  4. Expiry and Payouts: Detail your rules on expiry dates and explain what happens to unused TOIL when an employee leaves the company.
If you need a complete framework to get started, you don't have to reinvent the wheel. Our guide on how to simplify leave management with a template annual leave policy offers a helpful structure that you can easily adapt for TOIL.

The Pros and Cons of a TOIL System

Rolling out a system for days off in lieu can be a fantastic move for your business, but it's certainly not a silver bullet. Just like any new policy, it comes with its own unique set of benefits and potential headaches. It pays to weigh these up carefully before diving in.
From an employer's point of view, the biggest win is often financial. Offering time off instead of digging into the budget for overtime pay helps keep labour costs stable. It smooths out those unpredictable spikes in the wage bill that can follow a particularly demanding period.
For your team, the reward is often more valuable than cash: time. This extra flexibility can be a massive boost for morale and helps people feel more in control of their work-life balance. It gives them the freedom to handle personal appointments or just properly switch off, which is a win for everyone. After all, a well-rested team is a productive one.

The Benefits of a TOIL System

Let’s get into the specifics. A well-run TOIL system can bring some serious advantages to your organisation, often creating a positive loop where happy employees and smooth operations feed off each other.
  • Improved Employee Wellbeing: Handing back time allows your people to properly rest and recover. This is your best defence against the burnout that often follows long stretches of intense work.
  • Greater Flexibility: Staff can use the hours they've banked to deal with life's curveballs, fostering a much more supportive and understanding work environment.
  • Cost Management: It’s a smart way to handle peak workloads without letting your payroll costs spiral out of control with overtime payments.
This focus on taking time back is more important than ever. A 2023 YouGov survey found that 75% of UK workers were determined to use all or nearly all of their annual leave. Offering days off in lieu for extra work on bank holidays or weekends is a perfect way to help them do just that. If you're interested, you can read the full research about UK holiday habits.

The Challenges of a TOIL System

Now for the flip side. Running a TOIL system isn't always straightforward. One of the biggest hurdles is the admin. You need a rock-solid system to accurately track every extra hour worked, otherwise you open the door to mistakes and disputes.
The biggest risk of a poorly managed TOIL system is operational disruption. If too many employees accumulate and decide to use their lieu days at the same time, it can lead to significant staff shortages, especially during already busy periods.
Another thing to consider is that some people might just prefer the money. While many employees value their time, others might rely on that overtime pay to make ends meet. Taking that option away could lead to real dissatisfaction.
And what happens if your workplace culture is so full-on that people can never find a good time to take their accrued leave? The whole system backfires. Instead of reducing stress, it just adds another layer of it, which is the last thing anyone needs.

Common Questions About Days Off in Lieu

Even with a solid policy in place, the day-to-day reality of days off in lieu can throw up some tricky questions. Let's walk through some of the most common queries we see from both employees and managers, with some clear, straightforward answers to help you navigate things with confidence.
Getting these details right is what makes a TOIL system work smoothly. Without clear answers, small misunderstandings can easily spiral into bigger frustrations, undermining the very flexibility you were trying to create in the first place.

Does My Employer Have to Offer Me Days Off in Lieu?

In short, no. There’s no automatic legal requirement in the UK for a company to offer TOIL if you work overtime or on a bank holiday. Your entitlement comes down to one thing and one thing only: what’s written in your contract of employment.
If your contract doesn't mention it, then your employer isn’t obligated to provide it. Always check your contract and the company handbook first, as those documents are the final word on the matter.

Can My Employer Force Me to Take TOIL Instead of Overtime Pay?

Yes, they can, but again, it all hinges on your employment contract. If your contract clearly states that extra hours will be compensated with days off in lieu rather than cash, then that’s the deal you’ve agreed to.
If the contract is silent on the subject, you might have room to negotiate, but the company’s established practice will often carry the most weight. The key is what was agreed upon when you first joined the team.

What Happens to My Accrued TOIL If I Leave My Job?

This is a big one, and the answer—you guessed it—depends entirely on your employment contract or the company's TOIL policy. Some policies have a clear "use it or lose it" clause, meaning any unused lieu days must be taken before your last day.
Others might allow for a payout of the equivalent hours in your final pay packet, though this tends to be less common. If the policy isn’t clear, make sure you have a conversation with HR well before you leave to avoid any nasty surprises.
It's absolutely crucial for employers to have a clear clause covering what happens at termination. Stating that unused TOIL will not be paid out and must be used before the last day of employment is a common and legally sound approach, provided it's written into the policy.
This simple bit of foresight protects the business from unexpected costs when someone resigns. It also subtly encourages people to use their earned time off regularly, which is much better for work-life balance and stops huge amounts of leave from building up.
Let's be honest, the UK workforce isn't great at taking all its holiday. In 2023, just under 61% of UK workers didn't use their full annual leave allowance. With a statutory minimum of 20 days plus 8 bank holidays, days off in lieu offer a vital way for people to reclaim rest days lost to weekend work or public holidays, helping to ease some of that pressure. You can learn more about annual leave trends and see just how important these flexible options have become.

Is There a Time Limit for Using My Days Off in Lieu?

It's very common—and highly recommended—for companies to set an expiry date on TOIL. For example, a policy might say that lieu days must be used within three months of being earned.
This isn't about being difficult; it's a practical way to stop employees from stockpiling huge amounts of leave. That kind of backlog can become a real headache for the business to manage, both operationally and financially. Always check your company policy to see what rules apply to you.
Managing days off in lieu, keeping track of who has earned what, and making sure policies are followed can be a massive administrative headache.
