What is Time Off In Lieu (TOIL)?

Understanding TOIL and how it works for UK employers.

Time Off In Lieu (TOIL)is time off that an employee earns in exchange for working overtime. Instead of being paid extra for overtime hours, the employee receives equivalent time off at a later date. It's a flexible alternative to overtime pay that's popular with UK employers and employees alike.

The Calculation
TOIL hours = Overtime hours × Accrual rate
Then divide by standard day hours to get TOIL in days

TOIL accrual rates vary by employer. The most common is 1:1 (hour for hour), where each overtime hour earns one hour of time off. Some employers offer 1.5:1 (time and a half) or 2:1 (double time) for weekends, bank holidays, or unsociable hours.

There is no specific UK legislation governing TOIL — it depends on the employment contract and company policy. However, employers must still comply with the Working Time Regulations 1998, which cap average working hours at 48 per week (unless the employee has opted out). TOIL arrangements should be documented clearly.

TOIL FAQs

Common questions about Time Off In Lieu for UK employers.

1

What is TOIL?

Time Off In Lieu (TOIL) is compensatory time off given to employees in exchange for overtime worked. Instead of receiving overtime pay, the employee takes equivalent time off at a later date. The term "in lieu" means "instead of" — so TOIL is time off instead of extra pay.

2

Is TOIL a legal right in the UK?

No, there is no UK law that gives employees the right to TOIL. It is a contractual arrangement between employer and employee. However, the Working Time Regulations 1998 still apply — average weekly working hours must not exceed 48 hours unless the employee has opted out in writing.

3

What is a fair TOIL rate?

The most common TOIL rate is 1:1 (hour for hour), meaning one hour of overtime earns one hour of time off. Some employers offer enhanced rates such as 1.5:1 (time and a half) for weekends or 2:1 (double time) for bank holidays. The rate should be stated clearly in the employment contract or TOIL policy.

4

Does TOIL expire?

This depends on company policy. Many employers set a deadline by which TOIL must be taken (e.g. within 3 months of being accrued) and a cap on how much can be banked at any time. Without clear rules, TOIL balances can grow unchecked and become difficult to manage.

5

Can an employer refuse TOIL?

If TOIL is not part of the employment contract, an employer can choose not to offer it. If it is contractual, the employer must honour it but can set reasonable rules about when TOIL can be taken, subject to business needs. Clear policies help avoid disputes.

6

How can I track TOIL?

The simplest way to track TOIL is with leave management software like TimeTally. Create a custom leave type called "TOIL" with its own balance, and employees can request TOIL the same way they request annual leave. Their TOIL balance updates automatically when requests are approved.
