The Employment Rights Act 2025 (the Act) is bringing major reforms to the UK’s employment law landscape.
Among its provisions, the changes to collective redundancy rules stand out as particularly significant for businesses which in the current uncertain economic times may be considering restructuring and redundancies. We are still awaiting further details of some of the reforms following consultation and regulations (as detailed below), with the reforms expected to be phased in from April 2026 into 2027.
For in-house lawyers, the challenge is clear: engage with business stakeholders now about the changes coming and carefully plan any future restructuring proposals, to manage them effectively and mitigate the risk of costly tribunal claims.
In this blog, our In-House & Employment Solicitors explore the key changes to collective redundancy rules under the Employment Rights Act 2025, covering what in-house lawyers need to know.
What are collective redundancy consultation obligations?
Under the current rules:
- Where an employer proposes to make redundancies of 20 or more employees at one establishment within a period of 90 days or less, it must consult with elected representatives of affected employees.
- Consultation must begin in ‘good time’ and should start at least: 30 days before the first dismissal takes effect (where between 20 and 99 dismissals are proposed); or 45 days before the first dismissal takes effect (where 100 or more dismissals are proposed).
There is also a duty to notify the Secretary of State using the required HR1 Form as soon as possible within the minimum notification timescales set out above. The HR1 Form changed in December 2025 and also can only now be completed digitally, so businesses should ensure they are using the up to date form and completing it correctly.
What are the changes under the Act?
1. Changes to the collective redundancy consultation threshold (expected in 2027):
Employers will still be required to collectively consult where they propose to make redundancies of 20 or more employees at one establishment within a period of 90 days or less.
However, a new, alternative, threshold trigger will be introduced. We are awaiting the definition of this alternative trigger, but it will involve counting proposed redundancies across the whole of the employing entity (rather than by establishment). This alternative threshold may be set as a fixed figure, a percentage of the workforce or another formula.
When this comes into effect, given the need to count redundancies across the whole employing entity, this will mean that collective consultation obligations will potentially be triggered more often and result in longer consultation processes. Businesses will need to have internal systems in place to monitor, co-ordinate and manage proposals across all sites in the relevant entity to ensure compliance.
2. Doubling of the maximum protective award (from April 2026):
The maximum compensation that can be claimed by each employee where an employer fails to comply with its collective redundancy consultation obligations (i.e. the protective award) will double from April 2026, so the consequences of non-compliance will become more expensive for businesses.
- At the moment, the protective award is up to 90 days’ gross pay* per employee.
- From April 2026, the maximum award will double, taking it to up to 180 days’ gross pay* per employee.
* the statutory cap on a week’s pay does not apply
3. Notification of ship crew redundancies
At present, operators only need to notify the authority in the country where a ship is registered if redundancies affect crew on vessels registered outside Great Britain. Under the new rules, operators will also have to notify the UK Secretary of State if their ships regularly serve British ports. Failure to provide this notification could lead to an unlimited fine. This change is intended to strengthen protections for seafarers, following the mass dismissal of P&O Ferries employees without consultation in March 2022.
What is not changing under the Bill?
The minimum time periods for consultation will remain the same. The Government decided not to move forward with its proposal to extend the minimum consultation period for large-scale redundancies. Employers planning to dismiss 100 or more employees will still be required to begin collective consultation at least 45 days before the first dismissal, rather than the 90 days originally proposed.
What should in-house lawyers be thinking about?
1.Carefully consider the timing of any future restructuring:
If businesses are already considering future restructuring, they should think now about whether they can complete that before the changes to the collective consultation threshold trigger.
2.Track developments on, and plan for, the ‘new threshold’ trigger:
With a new organisation‑wide threshold (to be determined) triggering collective consultation obligations coming, businesses should start thinking now about the systems they will need in place to monitor redundancies across all sites to identify when collective consultation obligations are triggered. Training HR and management teams on these changes will be essential.
3. Advise stakeholders of the increased financial exposure
The doubling of the maximum protective award means the cost of non‑compliance will be far greater. Model potential liabilities and advise business stakeholders of the increased financial risks of non-compliance.
4. Consider the impact of the unfair dismissal reforms
From 1 January 2027 employees with 6 months’ service will get unfair dismissal rights (rather than having to wait the current 2 years). This means that, in practice, employees who started employment from July 2026 or before will acquire unfair dismissal rights when this reform takes effect. Business should consider whether this will have any impact on their future proposals e.g. because it will mean more affected employees will have unfair dismissal protection than would otherwise have been the case, impacting their approach to consultation / payments. The current cap on compensation for unfair dismissal claims will also be removed (although we are awaiting further consultation and details of when this change will come in).
