The Employment Rights Act 2025 is officially law in the UK as of 18 December 2025, marking a monumental shift in the way we work. For HR professionals and business owners, understanding the Employment Rights Act 2025 requires more than just a few milestones to cross.
While the Act became law in December 2025, it’s worth noting that the government has signaled that many of these major changes; specifically, the 6-month unfair dismissal qualifying period and the removal of the compensation cap. These changes are projected to take effect on January 1, 2027, while sick pay changes are expected in April 2026.

Employment Rights Act 2025: Your Questions Answered
Under the Employment Rights Act 2025, the government has pivoted away from the originally proposed “day one” rights. Instead, the qualifying period for ordinary unfair dismissal will be reduced from two years to a six-month qualifying period. This adjustment means that after six months of service, employees will gain full protection, making the six-month qualifying period a critical deadline for HR teams.
What is the new qualifying period for unfair dismissal in the UK?
Businesses should begin reviewing their probation management now, as the six-month qualifying period essentially limits the time available to assess a new hire’s suitability without significant legal risk. Failing to act within this six-month qualifying period could lead to costly tribunal claims.
Has the UK removed the unfair dismissal compensation cap?
Yes, one of the most significant changes under the Employment Rights Act 2025 is the removal of the unfair dismissal compensation cap. Previously, payouts were capped at roughly £118,000 or one year’s salary. By ensuring the removal of the unfair dismissal compensation cap, the government has opened the door for high earners to seek much larger damages.
For employers, the removal of the unfair dismissal compensation cap increases the financial stakes of every termination. HR leaders must recognize that the removal of the unfair dismissal compensation cap makes robust, legally sound dismissal procedures more vital than ever before. With the removal of the unfair dismissal compensation cap, a single procedural error could result in an unlimited financial award.
What is a “Guaranteed Hours Offer” for zero-hours workers?
A cornerstone of the Employment Rights Act 2025 is the new right to guaranteed hours for zero hours workers. This means that if an employee regularly works a set number of hours over a 12-week reference period, the employer must provide a right to guaranteed hours for zero hours workers that reflects those actual hours. This right to guaranteed hours for zero hours workers is designed to end “one-sided flexibility.”
Companies that rely on casual labor must implement systems to track these reference periods to honor the right to guaranteed hours for zero hours workers. Failing to provide a right to guaranteed hours for zero hours workers when requested can lead to significant penalties under the new Fair Work Agency.
How will the Act change Statutory Sick Pay (SSP)?
The Employment Rights Act 2025 introduces a statutory sick pay removal of lower earnings limit, ensuring that even the lowest-paid workers qualify for support. Alongside the statutory sick pay removal of lower earnings limit, the three-day “waiting period” is being abolished.
By implementing the statutory sick pay removal of lower earnings limit, the government expects to support over 1.3 million additional low-paid employees. HR departments must update payroll systems to reflect the statutory sick pay removal of lower earnings limit by April 2026. Ultimately, the statutory sick pay removal of lower earnings limit aims to ensure that no worker is forced to choose between their health and their paycheck.
Are there new restrictions on “Fire and Rehire”?
The Employment Rights Act 2025 effectively bans the practice of fire and rehire UK 2025 in most circumstances. Dismissing an employee to force through less favorable contract terms will now be considered automatically unfair. The only exception for fire and rehire UK 2025 is when a business is facing genuine, severe financial collapse.
This strict stance on fire and rehire UK 2025 means companies must engage in much more meaningful consultation before changing terms. Because fire and rehire UK 2025 is now so high-risk, legal experts advise against using it as a standard restructuring tool. The era of aggressive fire and rehire UK 2025 tactics has effectively come to an end.
What are the new “Day One” family rights?
Even though unfair dismissal is not “day one,” the Employment Rights Act 2025 does introduce day-one paternity leave and parental leave rights. This means that from the very first day of a new job, employees can access day-one paternity leave and parental leave without needing months of service. The shift to day-one paternity leave and parental leave is intended to help families manage the modern demands of work and life. Employers should update their handbooks to reflect that day-one paternity leave and parental leave is now a standard entitlement. Providing day-one paternity leave and parental leave is expected to benefit over 1.5 million parents across the UK.
