UK Sets Employment Rights Act Timeline: Six-Month Unfair Dismissal Rule Lands Jan. 2027

The UK Government has published an implementation timeline for the Employment Rights Act 2025, confirming the unfair dismissal qualifying period will drop from two years to six months on 1st January 2027 — with the cap on compensatory awards removed entirely. The update, published 22nd October 2026, gives employers and recruitment agencies a 14-month schedule of compliance deadlines running through December 2027.

The changes touch nearly every people-process: employment contracts, dismissal procedures, worker protections and supplier relationships. HR teams now face staggered go-live dates across trade union rights, harassment duties, family leave, NDA restrictions and umbrella company regulation.

What lands first?

On 30th October 2026 — just days after publication — new measures strengthen trade union access and representation rights. Employers also face increased responsibilities to prevent sexual harassment, now explicitly including harassment by third parties such as customers or clients.

Then comes the biggest shift for dismissal risk. From 1st January 2027, workers gain unfair dismissal protection after six months rather than two years, and the compensatory award cap disappears. Employers must also inform workers of their right to join a trade union.

Which obligations follow in 2027?

The schedule then accelerates through the year:

• March 2027 — New restrictions on fire and rehire (dismissal and re-engagement) take effect. Public authorities must produce mandatory gender equality and menopause action plans.
• April 2027 — New bereavement leave entitlements arrive, including leave for pregnancy loss. Changes to collective redundancy thresholds, extended blacklisting protections, and mandatory gender equality and menopause action plans for private and voluntary employers follow.
• September 2027 — New regulations restrict misuse of non-disclosure agreements in cases involving workplace harassment or discrimination.
• October 2027 — Enhanced dismissal protections for pregnant women and new mothers take effect, alongside reforms to flexible working.

What about zero hours contracts?

The Government has not yet set implementation dates for the zero hours reforms. These measures would give workers the right to guaranteed hours, reasonable notice of shifts, and compensation when shifts are cancelled or changed at short notice. Further details will follow the consultation process.

That gap matters for staffing agencies and shift-based employers, who can't yet model the cost or scheduling impact of guaranteed-hours obligations.

How will umbrella companies be regulated?

December 2027 is the confirmed target date for formal regulation of umbrella companies. Umbrellas will come within the regulatory framework governing employment agencies and employment businesses, introducing greater oversight and enforcement across the sector.

For recruitment agencies, it marks another significant step in how umbrella providers are regulated, aiming to improve standards, transparency and protections for workers.

What should employers do now?

The Government has confirmed all implementation dates remain subject to parliamentary processes, and timings for guaranteed hours and shift notice reforms are still to be finalised. Agencies should review existing practices across contracts, dismissal procedures and supplier relationships before the deadlines bite.

With the first tranche — trade union rights and third-party harassment duties — effective 30th October 2026, the preparation window for the earliest measures has already closed.
