TOIL vs Overtime Pay UK: Which Is Better for Your Business? (2026)
Should you offer TOIL or overtime pay to UK employees? Compare cost implications, legal requirements, employee preferences, and discover which approach suits different business types.
The Core Question: Cash Now or Time Later?
When an employee works extra hours beyond their contracted time, you face a choice: pay them for those hours now, or give them equivalent time off later. Both approaches are used widely across the UK, and neither is inherently better than the other. The right answer depends on your business model, cash flow, workforce, and culture.
This guide breaks down TOIL (Time Off In Lieu) and overtime pay side by side — covering cost, legality, employee preference, and practical management — so you can make an informed decision for your team.
What Is TOIL (Time Off In Lieu)?
TOIL is an arrangement where employees who work beyond their contracted hours receive paid time off instead of extra pay. For example, an employee who works three hours late on a Tuesday could take three hours off (or a proportionate time, depending on your TOIL rate) at a later date.
TOIL is not a legal right in the UK — it must be agreed contractually or through a workplace policy. Our complete TOIL guide covers everything you need to know about setting up a TOIL policy, including accrual rates, caps, and expiry rules.
Common TOIL accrual rates in the UK are:
- 1:1 (hour for hour) — one hour of overtime earns one hour of TOIL. The most common approach.
- 1.5:1 (time and a half) — one hour earns 1.5 hours. Often applied for evening or weekend work.
- 2:1 (double time) — one hour earns two hours. Used for bank holidays or particularly unsocial shifts.

What Is Overtime Pay?
Overtime pay means compensating employees directly for extra hours worked, at the time those hours are paid through payroll. Common overtime pay rates include:
- Straight time — the regular hourly rate for all extra hours. The minimum legal requirement (as long as average pay stays above National Minimum Wage).
- Time and a half (1.5x) — 50% more per hour. A widely used incentive rate.
- Double time (2x) — twice the hourly rate. Typically reserved for bank holidays or emergency call-ins.
Unlike TOIL, overtime pay is settled immediately through payroll. There is no future obligation on the employer beyond the next pay run.
TOIL vs Overtime Pay: Direct Comparison
| Factor | TOIL | Overtime Pay |
|---|---|---|
| Immediate cost | None — paid leave is deferred | Immediate payroll cost |
| Future liability | Yes — accrued TOIL must be used or paid out | None — settled in payroll |
| National Insurance | None at point of accrual | NI due on overtime earnings |
| Admin burden | Requires tracking accrual and usage over time | Processed through payroll each period |
| Employee preference | Suits those who value flexibility and extra time off | Suits those who need or prefer extra income |
| Wellbeing impact | Encourages rest and recovery after intense periods | Financial reward without guaranteed recovery time |
| Staffing risk | Staff taking TOIL can affect operational cover | No absence impact — payment is immediate |
| When employee leaves | Unused TOIL may need to be paid out | Nothing outstanding — already paid |
The Real Cost of TOIL
TOIL is often seen as the “cheaper” option because there is no immediate payroll cost. In cash flow terms, this is true — but TOIL represents a real financial obligation. When an employee takes TOIL, you are still paying their salary while they are not at work, and you may need to bring in cover.
The key risk with TOIL is balances growing unchecked. An employee who accumulates 10 days of TOIL without using it is effectively owed two weeks of paid leave. If they then resign, you may need to pay this out in their final pay, potentially at a time when you can least afford it.
TOIL Liability Example
A salaried employee earning £30,000 per year (approx. £115/day) accrues 10 days of unused TOIL over six months, then hands in their notice.
10 days × £115 = £1,150 potential payout
Whether this is legally required depends on your contract terms and TOIL policy. Always specify what happens to unused TOIL when an employee leaves.
The Real Cost of Overtime Pay
Overtime pay has the opposite profile: the cost is immediate and certain. For hourly workers, you can calculate the exact overtime cost before approving extra hours. The upside is that once paid, there is no future liability.
One factor employers often overlook is National Insurance. Overtime earnings are subject to employer NI contributions (currently 13.8% for most employers), which means overtime pay has an additional cost beyond the raw hourly rate. TOIL avoids this because no additional payment is made at the point of accrual.
For businesses tracking staff costs carefully, our timesheet tracking software captures both regular and overtime hours, giving you clear data on labour costs before they hit payroll.
What Do UK Employees Prefer?
Employee preference depends heavily on personal circumstances and the nature of the overtime being worked:
Those with financial commitments prefer overtime pay
Employees with mortgages, childcare costs, or other financial pressures often prefer cash in hand. Extra time off may be less valuable to them if they cannot use it or would spend it looking for extra income.
Those who value flexibility prefer TOIL
Salaried professionals, parents with school-age children, or employees who simply want a better work-life balance often prefer TOIL. A day off to recover after a big project or attend a child's school play can be worth more than the equivalent pay.
High earners tend to prefer time off
For employees on higher salaries, the marginal utility of extra income decreases — an extra £100 matters less if you already earn £60,000. For these employees, an extra day off is often more valuable.
Shift workers often prefer overtime pay
In shift-based environments like hospitality and healthcare, TOIL can create rota headaches. Employees may find it difficult to take TOIL at times that work for them — and managers find it difficult to approve absence in already-stretched teams. Overtime pay settles the matter cleanly.
UK Legal Considerations
Neither TOIL nor overtime pay is automatically required by UK law — but several legal obligations apply regardless of which approach you choose:
National Minimum Wage
Whether you use TOIL or pay overtime, all employees must receive at least the National Minimum Wage when their total hours worked are divided into their total earnings. If someone works 50 hours but is only paid for 40, their effective hourly rate must still meet NMW for all 50 hours.
Working Time Regulations
The Working Time Regulations 1998 limit average weekly working time to 48 hours (calculated over 17 weeks), unless an employee has signed an opt-out agreement. This applies regardless of whether extra hours are compensated by TOIL or overtime pay.
Rest Breaks
Employees are entitled to 11 consecutive hours of rest between working days, and a 20-minute break when working more than 6 hours. TOIL and overtime arrangements do not override these minimums.
Holiday Entitlement
The UK statutory annual leave entitlement of 28 days (including bank holidays) cannot be replaced by TOIL. TOIL is a separate arrangement on top of statutory holiday.

Hybrid Approaches: TOIL and Overtime Together
Many UK businesses use a hybrid model, offering TOIL to some employees and overtime pay to others based on their role or working pattern:
Salaried staff: TOIL
For salaried employees, calculating an exact hourly overtime rate is less natural. TOIL fits well here because extra hours are compensated with equivalent time off rather than an additional payment on top of salary. Most professional services firms, agencies, and office-based businesses use TOIL for their salaried workforce.
Hourly workers: Overtime pay
For hourly workers — particularly in retail, hospitality, construction, and logistics — overtime pay is more natural. Their contracts are already based on an hourly rate, and overtime pay simply extends this. TOIL can be harder to manage in shift-based environments where rota coverage is critical.
Senior staff: Employee choice
Some businesses give senior employees the option to choose. After a busy period, the employee can elect to take TOIL or receive overtime pay for approved extra hours. This adds flexibility but also requires a robust tracking system.
When TOIL Works Best
Project-based or variable workloads
When teams have bursts of intense work followed by quieter periods — product launches, year-end accounts, campaign delivery — TOIL lets employees recover during the quieter phase.
Cash-flow-conscious businesses
Start-ups and small businesses with tight cash flow benefit from TOIL because there is no immediate payroll cost. The liability is deferred, giving the business more financial flexibility.
Culture of flexibility and work-life balance
If your employer brand emphasises flexibility, offering TOIL reinforces that culture. It signals that you value employee wellbeing beyond just financial compensation.
When Overtime Pay Works Best
Shift-based and rota-driven businesses
When every shift needs to be covered, allowing employees to take TOIL at will is operationally difficult. Overtime pay settles the extra hours without creating a future absence obligation.
High-turnover workforces
When staff turnover is high, accumulated TOIL balances can become a liability that is difficult to manage. Paying overtime immediately prevents balances building up across a revolving workforce.
When employees genuinely need the income
For lower-paid employees where extra income makes a real difference, TOIL may be perceived as withholding something they have earned. Overtime pay is more straightforward and honest in these situations.
How to Manage TOIL Effectively
If you decide that TOIL is the right approach for your business, good management is essential to prevent the common pitfalls:
- Write a clear TOIL policy — cover eligibility, accrual rates, caps, expiry periods, and what happens when an employee leaves. Download our free TOIL policy template as a starting point.
- Pre-approve all overtime — TOIL should only accrue for pre-approved overtime, not for any extra hours an employee chooses to work unilaterally.
- Set a cap — limit how much TOIL an employee can accrue (commonly 1–5 days). This prevents balances becoming unmanageable.
- Set an expiry period — require TOIL to be used within a defined window (e.g. 3 months of accrual). This keeps balances moving.
- Track it properly — use dedicated TOIL management software rather than spreadsheets. With TimeTally, TOIL is a custom leave type that employees request and managers approve through the same workflow as annual leave, so balances are always accurate.

Key Takeaways
- TOIL and overtime pay are both valid — neither is legally required in most situations, and the right choice depends on your business.
- TOIL has no immediate cash cost but creates a future liability that must be managed carefully.
- Overtime pay has an immediate payroll cost (including National Insurance) but creates no future obligation.
- Salaried, office-based employees tend to suit TOIL; hourly, shift-based workers often suit overtime pay.
- A hybrid model — TOIL for salaried staff, overtime pay for hourly workers — is common and practical.
- Whichever you choose, track it properly. Unmanaged TOIL balances or disputed overtime claims are both avoidable with the right system.
