Employment Rights Act 2025: Unfair Dismissal Changes Explained

The Employment Rights Act 2025 brings some important changes to employment rights and unfair dismissal law that employers need to be aware of. While these changes don’t come into force straight away, they will affect how you manage probation periods, performance issues and dismissals in the future.

Below, we explain what’s changing, when it’s happening, and what it means for you as an employer. In particular, understanding the new landscape of employment rights is crucial.

What’s Changing?

Shorter Qualifying Period for Unfair Dismissal

At the moment, employees need two years’ service before they can bring an ordinary unfair dismissal claim. Under the new Act, this will reduce to six months. This means employees will gain protection much earlier, and employers will need to ensure dismissals within the first year are handled fairly and consistently under the updated rights for employment.

Written Reasons for Dismissal

Currently, employees can usually only request written reasons for dismissal after two years’ service. This will also change to six months, meaning employers will need to clearly explain and document dismissal decisions much earlier in the employment relationship, with attention to statutory employment rights.

Protection Linked to Spent Convictions

The Act removes the qualifying period entirely where a dismissal relates to a spent conviction. In these cases, employees will be protected from unfair dismissal from day one, ensuring their employment rights are upheld.

Removal of the Compensation Cap

At present, compensation for unfair dismissal is capped at the lower of:

  • £118,223, or
  • 52 weeks’ gross pay

Under the new Act, this cap will be removed completely. Tribunals will be able to award compensation based on the employee’s actual financial loss. While most awards are currently well below the cap, this change increases potential risk for employers where dismissals are not handled properly. Furthermore, robust rights in employment are now essential to reduce exposure to claims.

What Isn’t Changing?

Some key protections already apply from day one, and this remains the case. These include:

  • Discrimination claims
  • Automatically unfair dismissal (such as whistleblowing or health and safety reasons)

The Act does not change these existing rights, so fundamental employment rights stay protected.

How Is This Different From the Current Law?

In simple terms, the new Act makes significant adjustments to employment rights and protections compared to current law:

Now

  • 2 years’ service needed for unfair dismissal claims
  • 2 years to request written reasons
  • Compensation capped

From 1st January 2027

  • 6 months’ service needed
  • 6 months to request written reasons
  • Compensation uncapped

When Will These Changes Take Effect?

The Government plans to bring these changes into force on 1 January 2027, altering requirements for employment rights.

From that date:

  • Employees with six months’ service or more will gain protection immediately
  • Employees with less than six months’ service will gain protection once they reach six months

Why Six Months and Not Day One?

You may be wondering why the Government hasn’t introduced unfair dismissal protection from day one when revising employment rights.

The reasoning is:

  • Six months was agreed as a workable compromise between employers and trade unions
  • It still allows employers time to assess performance and suitability
  • It avoids adding too much risk at the very start of employment

This approach puts the UK among countries with some of the strongest unfair dismissal protections, while keeping probation periods meaningful and balancing employment rights for all parties.

Why Has the Compensation Cap Been Removed?

The Government believes:

  • Employees should be fully compensated for genuine financial loss
  • Removing the cap discourages unfair dismissals being treated as a “cost of doing business”, reinforcing employment rights in workplaces.
  • It may reduce the number of complex claims where discrimination is added mainly to access uncapped compensation

In practice, most unfair dismissal awards are modest, regardless of the strengthened employment rights.

What Do these Employment Rights Changes Mean for Employers?

Although these changes won’t apply until 2027, they will require a shift in approach, particularly around employment rights.

Employers should start thinking about:

  • Stronger probation and performance management processes
  • Clear documentation and fair decision-making earlier in employment
  • Training managers to handle dismissals carefully, even within the first year
  • Reviewing contracts, policies and procedures regarding employment rights in detail

Good HR practice will be more important than ever, ensuring compliance with all new requirements related to employment rights.
