Tips for Businesses
Keep trial periods short and focused on assessment. Supervise candidates and avoid assigning productive work. If the trial exceeds a few hours or resembles real work, pay at least the National Minimum Wage. Document the recruitment purpose and apply a consistent process to reduce legal risk.
An unpaid trial period is a short work assessment used to evaluate a candidate’s suitability before hiring, but UK law does not clearly define when it must be paid. For your business, this creates legal risk, as trials that are too long or provide real value may trigger National Minimum Wage obligations and potential claims. You must structure trials carefully to avoid breaching employment law or exploiting candidates. This article explains when unpaid trial periods are lawful in the UK, the key factors to consider and how to manage compliance.
What is a Trial Period of Work?
A trial period of work is sometimes known as a:
- trial shift;
- test period;
- a recruitment exercise period; or
- a trial work period.
Unpaid Trial Periods of Work- Basics
The UK law does not contain detailed provisions clearly setting out whether you are required to pay a person for trial work. As such, work trials are a grey area. However, the government has provided guidance as to when an employer should be paying the National Minimum Wage (minimum wage) in respect of a trial period. As an employer, you can ask a potential employee to carry out work as part of a trial before committing to entering into an employment contract.
Moreover, while unpaid trial work can be a legitimate exercise for recruitment purposes, it may also be used to exploit workers. To prevent exploitation, the government outlines key factors for determining whether a trial period should be paid, which are examined below.

Factors to Take Into Account When Offering Unpaid Trial Periods of Work
As an employer considering an unpaid trial, you should consider some key factors. These factors will help you decide whether it is fair for you to ask for a trial shift without offering payment.
An unpaid trial shift should be only as long as you reasonably need to decide whether the potential employee can do the job. Generally speaking, it is unlikely that an unpaid trial shift should last more than a couple of hours. If a trial lasts longer than this, you should start to pay the worker the National Minimum Wage.
Other factors may determine whether you need to pay a person carrying out a trial period of work the minimum wage. These include whether the:
- trial period of work is genuinely part of the recruitment tasks;
- length of the trial period of work is not more than reasonably needed to test the person’s capability in carrying out the work;
- a person on a trial period of work is being watched and assessed;
- tasks the person is being asked to do represent those of the job;
- tasks provide no value beyond testing the candidate, such as in a simulated environment;
- trial period does not enable you as an employer to reduce your workforce in place of the person carrying out the trial period.

Deciding Whether or Not You Should Pay For a Work Trial Period
Whether or not you should pay for a work trial period is decided on a case-by-case basis. This is done where necessary by HMRC or by courts and tribunals. The main point they will consider is the exact nature of the arrangement, which will include the:
- length of the trial period; and
- tasks the person is carrying out.
However, there are circumstances when the law allows unpaid trial periods of work where the minimum wage does not apply. This is known as the government’s Work Trial scheme through the JobCentre Plus. This scheme allows jobseekers on benefits to complete an unpaid trial with a guaranteed job if successful, while continuing to receive their benefits during the trial.
Key Takeaways
As an employer, you should employ staff you believe are capable of the job you are offering them. To determine this, you may decide to offer a potential employee an unpaid trial period of work. Unfortunately, no clear rules surround this, and each situation is decided on a case-by-case basis. By reviewing the relevant guidance, you can better decide whether to offer an unpaid trial period. Ensure the trial’s length and nature are fair and non-exploitative, and comply with minimum wage obligations.
To minimise legal risks associated with unpaid trial periods, employers should:
- keep trials short, ideally not exceeding a few hours;
- ensure the trial has a genuine recruitment purpose;
- closely supervise and observe candidates during the trial;
- assign tasks directly relevant to the job offered;
- avoid having candidates perform work that significantly benefits the business;
- document the recruitment process, including the purpose and structure of the trial;
- consider paying at least the National Minimum Wage for trials lasting more than a few hours;
- be consistent in your approach to all candidates; and
- seek legal advice if unsure about the appropriateness of an unpaid trial.
