What protections apply after 12 weeks?

After 12 continuous calendar weeks in the same role with the same hirer, agency workers gain the right to equal treatment in basic working and employment conditions.

In UK law, the Agency Workers Regulations 2010 provide that after a qualifying period of 12 calendar weeks in the same assignment, an agency worker is entitled to the same basic working and employment conditions as a directly recruited employee or worker in the same role. This is known as parity of treatment and covers matters such as pay, duration of working time, rest breaks, holidays, and access to facilities.

The 12-week period is counted in calendar weeks, and it is the continuous nature of the assignment that matters. If you have a break between assignments or a substantial gap, the 12-week clock can be reset or treated differently under the Regulations. If you remain in the same role with the same hirer, the clock keeps ticking week by week.

A simple example: if you have worked in the same role for 11 straight calendar weeks, you have not yet hit parity. Once you reach 12 weeks, you swap to parity, assuming there are no disqualifying breaks. These rules help prevent employers from using temp roles to avoid direct contractual rights.

• Parity applies to: pay for the same job and hours
• Parity applies to basic working time and holidays
• Access to facilities and information about the assignment
• The qualifying period is 12 calendar weeks
• Breaks between assignments can affect continuity if they are long enough
• The rules aim to prevent unequal treatment between agency workers and directly employed staff

Pay and basic conditions: parity after 12 weeks

The 12-week qualifying period triggers parity of pay and other basic terms with the hirer’s directly employed staff.

Once the 12-week qualifying period is reached, the agency worker should be paid the same basic pay and given the same basic working conditions as a comparable employee or direct worker in the same role. This includes the rate of pay for the hours worked and the standard terms and conditions that ordinarily apply to the hirer’s staff.

Remuneration includes weekly pay, as well as other elements such as holiday pay, certain bonuses, and other emoluments connected to the role, where these are ordinarily included in the contracts of employees in the same role. Some payments, such as certain sickness payments, may be treated differently under a contract and are not part of the parity calculation.

This parity does not automatically replace contractual pay or non-pay benefits already agreed in the agency worker’s contract; rather, it ensures that the basic pay and conditions align with those of the hirer’s employees where the worker has reached parity.

• Same pay for the same job and hours after 12 weeks
• Holiday entitlement aligned with the employer’s staff
• Rest breaks and working time aligned with the employer’s staff
• Bonuses and other non-basic pay may be included where customary
• Parity is assessed against a comparable employee or worker
• Contractual variations may still apply if they are not part of the basic terms

Facilities and information: what agency workers should get

Agency workers seeking parity can expect access to facilities and to information about the assignment.

Agency workers who have reached parity should have access to the same basic facilities as directly employed staff in the same role. This includes reasonable access to facilities such as canteens, rest areas, and access to relevant information about the assignment and the terms that apply to the role.

• Access to basic facilities
• Information about the assignment and its terms
• Support and welfare facilities on site
• Equivalent access to HR and payroll information

Protection from detriment and equality rights

Agency workers are protected against detriment for asserting rights and are covered by equality law.

Agency workers are protected from detriment if they exercise their rights under the AW Regulations or raise concerns about pay and conditions. Under the Equality Act 2010, workers also enjoy protection from discrimination and harassment, and there are additional protections related to pregnancy, religion, age, disability, and other protected characteristics.

If a breach occurs, a tribunal can consider remedies including declarations, compensation and often orders requiring action to prevent repetition. This protection helps ensure agency workers can enforce their rights without fear of retaliation.

• Right not to be subjected to detriment for asserting rights
• Prohibitions on unlawful discrimination
• Protection extends to pregnancy, disability, and other protected characteristics
• Tribunals can order remedies to address breaches

Enforcement: remedies and time limits

If rights are breached, remedies may include declarations, compensation, and recommendations; there are strict time limits to bring claims.

If an agency worker’s rights under the AW Regulations or related employment law have been breached, a complaint can be made to an Employment Tribunal. The tribunal can award relief including a declaration of rights, compensation for loss, and recommendations requiring action by the employer or hirer to remedy the breach.

Time limits exist for bringing claims to the tribunal, and claims often rely on the standard three-month window from the date of the breach or the last act in a series of breaches; discrimination claims may have extended time limits in some circumstances. You should also consider ACAS Early Conciliation, which must be started within a defined window and completed before a tribunal claim can proceed.

What to do next: gather evidence (payslips, communications, diary notes), consult ACAS guidance, and seek free or low-cost advice if possible.

• Tribunal remedies: declarations, compensation, and recommendations
• Time limits: usually three months from breach
• ACAS Early Conciliation often required before tribunal
• Evidence is important for credibility and remedies

1. Step 1: Identify the breach and gather documents
2. Step 2: Contact ACAS for Early Conciliation within the time limit
3. Step 3: Lodge a claim with the Employment Tribunal within the limit
4. Step 4: Prepare evidence and seek help if needed

Conclusion

Understanding agency worker rights helps you prepare and protect your position in the workplace.

Agency worker rights in UK law provide important protections after a qualifying period of 12 weeks in the same role. The five key protections covered here—parity in pay and conditions, access to facilities and information, protection from detriment, and formal remedies—help ensure agency workers are treated fairly and have practical avenues to enforce their rights.

If you work through a temporary agency, knowing these protections can help you assess contracts, raise concerns effectively, and access support from ACAS or a legal adviser when needed. Remember that time limits apply to claims, so act promptly if you believe your rights have been breached.

Key takeaways

– After 12 weeks in the same role, agency workers gain parity with the hirer’s staff in basic pay and conditions for the same role.

– Pay and other terms should reflect the same level of treatment as comparable employees; check your payslip and holiday entitlement.

– You have protections against detriment for exercising your rights, and discrimination protections apply under the Equality Act 2010.

– If things go wrong, tribunals can award declarations, compensation, and actions to prevent repeat breaches.

– Time limits apply to claims; start with ACAS Early Conciliation to protect your rights and avoid losing the chance to make a claim.
