Collective Redundancy Consultation Rules
Sep 10, 2026

When an employer is planning significant job cuts, collective redundancy consultation is not a procedural formality. It is a legal process designed to give employees and their representatives a genuine opportunity to influence the proposal before dismissals take effect. For employers, getting it wrong can lead to costly protective awards and serious damage to workplace trust. For employees, understanding the process can help them challenge an unfair approach early.

When collective consultation is required

An employer must collectively consult where it proposes to dismiss as redundant 20 or more employees at one establishment within a 90-day period. The obligation applies whether the proposed redundancies arise from a site closure, reduced demand, financial pressure, restructuring or a change in the way work is organised.

The threshold can be more complicated than it first appears. Whether workers are employed at the same establishment is a question of fact, particularly for businesses with several sites, remote teams or regional operations. Employers should assess the position carefully rather than treating each department or location as automatically separate.

The duty begins when redundancies are proposed, not when every detail has been settled. An employer may have a legitimate commercial rationale and a preferred structure in mind, but it must not present the outcome as final. Consultation has to be capable of changing the decision, the number of dismissals, the selection approach or the support offered to affected staff.

The minimum consultation periods

The minimum period depends on the number of proposed dismissals. Where 20 to 99 employees may be dismissed, consultation must start at least 30 days before the first dismissal takes effect. Where 100 or more employees may be dismissed, the minimum period is 45 days.

These are minimum periods, not targets. A complex restructure may require longer, especially where there are multiple job groups, detailed selection exercises, redeployment opportunities or significant changes to terms and conditions. Starting consultation too late and attempting to compress a difficult process into 30 or 45 days creates avoidable legal risk.

Notice can be a sensitive issue. Employers should plan the sequence of consultation, individual meetings and notice periods carefully. The key statutory requirement is that no dismissal takes effect before the relevant minimum period has passed, but meaningful consultation must take place before the employer has made an irreversible decision.

Who must be consulted?

If a recognised trade union is entitled to bargain for the employees affected, the employer must consult that union. If there is no recognised union, consultation must take place with existing employee representatives who have authority to be consulted about redundancies, or with representatives elected specifically for the process.

The election process matters. Employees affected by the proposals must have a real opportunity to stand and vote, and the employer must ensure there are enough representatives to reflect the affected workforce. Representatives must also be given enough time and facilities to understand the proposals, obtain advice and communicate with colleagues.

Employers cannot avoid collective consultation by speaking only to individuals. Individual meetings remain necessary, particularly where selection, alternative employment or personal circumstances are being considered. However, they do not replace consultation with trade union or employee representatives when the collective threshold is met.

What information must employers provide?

The employer must provide the representatives with written information in good time. This is what allows them to question the business case, test the numbers and make constructive counter-proposals. The information should cover:

  • the reasons for the proposed dismissals;
  • the number and description of employees it proposes to dismiss;
  • the total number and description of employees of that type employed at the establishment;
  • the proposed selection method;
  • the proposed way of carrying out the dismissals, including the period over which they are to take effect; and
  • the proposed method of calculating redundancy payments, where this differs from the statutory method.

In practice, useful consultation often requires more than the bare statutory information. Representatives may reasonably need the proposed organisational chart, affected job roles, scoring guidance, financial context, vacancy information and details of any voluntary redundancy scheme. The appropriate level of disclosure depends on the proposal, but withholding relevant information can make it difficult to show consultation was genuine.

What must the consultation cover?

The legal purpose of consultation is clear. The employer must consult about ways of avoiding dismissals, reducing the number of employees dismissed and mitigating the consequences for those dismissed.

That may involve considering a recruitment freeze, reduced overtime, limits on agency labour, voluntary redundancy, flexible working arrangements, temporary reductions in hours, redeployment or retraining. Not every suggestion will be practical or affordable. Employers are not required to accept every alternative proposed by representatives, but they should consider suggestions openly, explain their reasoning and keep a clear record of decisions.

For employees, this is an opportunity to raise practical alternatives that a leadership team may not have considered. A proposed role merge may overlook transferable skills. A redundancy pool may be too narrow. A vacant role might provide suitable alternative employment. Representatives should collect evidence and questions from the workforce rather than simply receiving updates from management.

Individual fairness still matters

A compliant collective process does not automatically make an individual dismissal fair. Employers must also consult affected employees individually, apply a fair selection process where selection is required, consider suitable alternative employment and comply with contractual and statutory redundancy pay obligations.

Selection criteria should be objective, relevant and consistently applied. Criteria based on attendance, performance or disciplinary history require particular care, as they can create discrimination risks where absence is connected to disability, pregnancy, maternity or other protected circumstances. A scoring matrix should be supported by evidence, not retrospective justification.

Employees with two years’ service will often have the right to claim statutory redundancy pay and may have unfair dismissal rights. Some claims, including discrimination and whistleblowing claims, do not require two years’ service. This is why an apparently routine redundancy exercise can become contentious if the process has been rushed or a protected issue has been overlooked.

The HR1 notification requirement

Where collective consultation is required, the employer must also notify the Secretary of State using an HR1 form. This is a separate obligation from consulting employees or their representatives.

Failure to submit the HR1 can be a criminal offence for the company and, in certain circumstances, its officers. It should be treated as part of the project plan from the outset, alongside the consultation timetable and communications strategy. Sending the form does not cure a poor consultation process, but overlooking it creates an additional and unnecessary exposure.

Consequences of getting it wrong

If an employer fails to comply with its collective consultation obligations, an employment tribunal can make a protective award of up to 90 days’ gross pay for each affected employee. The award is intended to be punitive as well as compensatory. Tribunals will consider the seriousness of the employer’s default, and a complete failure to consult can lead to a substantial award.

A protective award is separate from statutory redundancy pay, notice pay, unfair dismissal compensation and discrimination compensation. The financial consequences can therefore escalate quickly, particularly in a larger redundancy programme. There may also be consequences for employee relations, staff retention and an employer’s reputation at a time when it needs confidence from the remaining workforce.

Employees should act promptly if they believe consultation has not taken place or has been merely cosmetic. A complaint about a protective award normally has to be presented to the tribunal within three months of the last dismissal taking effect, subject to the Acas early conciliation process. Tribunal deadlines are strict, so it is sensible to obtain advice before time runs out.

A practical approach for employers and employees

For employers, the strongest approach is to prepare the commercial case, identify the likely affected groups and build consultation into the timetable before any final announcements are made. Clear written information, properly elected representatives where required, documented responses to proposals and carefully managed individual meetings will put the business in a far stronger position.

For employees and representatives, focus on the questions that can alter the outcome: why are these roles affected, how was the pool chosen, what alternatives have been assessed, which vacancies exist and how will selection scores be evidenced? Keep notes of meetings and ask for key information in writing where it has not been provided.

Redundancy decisions can carry significant financial and personal consequences on both sides. Early, tailored employment law advice can help employers manage the process with confidence and help employees protect their rights while there is still time for consultation to make a difference.
