Consultation Period Of Redundancy: What UK Employers Need To Know

Thinking about making redundancies in your business? If so, you’ll want to be absolutely sure you’re following the rules around the consultation period of redundancy. While redundancy can sometimes be a necessary business decision, UK employment law is strict when it comes to how you approach it - and the consultation period is one of the most crucial parts to get right.

If you’ve never navigated this process before, it’s natural to feel some uncertainty. Mistakes or missed steps can lead to legal claims, financial penalties, or damage to your reputation. But don’t stress - with clear guidance and a little bit of preparation, you can handle redundancies in a professional and compliant way.

This guide will break down what the consultation period of redundancy means, when it applies, how to navigate it, and the key legal steps every employer should know to avoid pitfalls. Let’s get you up to speed so you can make any necessary changes the right way - and keep your business protected.

What Is The Consultation Period Of Redundancy?

The consultation period of redundancy is the legally required time where you, as an employer, must formally consult with affected employees before their roles are made redundant. The main aim is to discuss the proposed redundancies, explore alternatives, and ensure employees have a chance to put forward suggestions, ask questions, and feel heard.

In the UK, redundancy consultation requirements are set out in both individual redundancy and collective redundancy scenarios:

• Individual redundancy: You must still consult, but this is less formal and does not have a set minimum timeframe.
• Collective redundancy (20 or more redundancies in a 90-day window): You are legally required to follow statutory consultation periods and specific processes.

Failing to carry out a proper consultation can make the redundancy “unfair”, giving employees grounds for an unfair dismissal claim at an employment tribunal.

When Does The Consultation Period Of Redundancy Apply?

The consultation period of redundancy applies if you’re planning to make employees redundant due to organizational restructure, downturn in business, new technology, or other similar business reasons.

UK law draws a clear distinction between:

• Redundancy affecting fewer than 20 employees: You must still consult individually, but there’s no statutory minimum period - it just needs to be “meaningful”.
• Redundancy affecting 20 or more employees at one establishment within 90 days (collective redundancy): You must follow detailed collective consultation rules and adhere to set minimum periods.

If you’re not sure whether your planned staffing changes count as “redundancy”, it’s wise to check early. Read our full guide to UK redundancy laws for the key triggers and legal definitions.

How Long Is The Consultation Period For Redundancy?

The minimum length of the redundancy consultation period (for collective redundancies) depends on how many employees are affected:

• 20-99 redundancies: Consult for at least 30 days before the first dismissal takes effect.
• 100 or more redundancies: Consult for at least 45 days before the first dismissal takes effect.

For fewer than 20 redundancies, the law is less prescriptive. However, best practice is to allow enough time for a genuine, two-way discussion. In reality, even for small redundancies, most employers allow at least 1-2 weeks for consultation.

Remember, these are minimum periods. Rushing the process or allowing too little time is a common - and costly - mistake.

What Happens During The Redundancy Consultation?

Whether you’re dealing with an individual or collective redundancy, the consultation period is your opportunity to:

• Explain why redundancies are being considered and provide details about the process
• Listen to employee input, suggestions, or alternatives to redundancy (e.g., reduced hours, redeployment)
• Discuss the criteria used to select employees for redundancy
• Consider any representations made and respond to them before making a final decision
• Cover rights on redundancy pay, notice, and support (such as help finding new work)

For collective redundancies, you must consult with employee representatives (such as union or elected reps), not just the affected individuals. The rules are strict and you must ensure that representatives have the resources and information they need to meaningfully engage in the process.

What Is A “Meaningful” Consultation Under UK Law?

It’s not enough to simply announce redundancies - UK law requires that consultation must be “genuine and meaningful”. That means:

• You enter into the consultation before any final decisions are made
• Employees (or their representatives) are given relevant information and opportunities to ask questions
• Sufficient time is allowed for discussion and alternative proposals
• You must genuinely consider those proposals (not just “go through the motions”)

Failing to engage seriously or making up your mind before consulting can open your business to claims for unfair dismissal or, in collective situations, a protective award (compensation equal to up to 90 days’ pay per affected employee).

What Information Must Be Provided During Redundancy Consultation?

In collective redundancies, you’re required to provide employee reps (in writing):

• Reasons for redundancies
• Number and descriptions of roles at risk
• Proposed selection criteria and process
• How dismissals will be carried out and the timeline
• How redundancy pay and other entitlements will be calculated

For individual redundancies, much of this information will still be expected. Clear, transparent communication is essential to show that the process is fair and defend your decision if challenged.

Do I Need To Notify The Government About Redundancies?

Yes, for collective redundancies (20 or more roles in 90 days at one establishment), you must inform the government by notifying the Redundancy Payments Service (RPS) using the HR1 form before starting consultation.

Failing to do so is a criminal offence, and directors or senior managers could be prosecuted personally.

What Legal Risks Do Employers Face If They Get The Consultation Period Wrong?

Skipping or mishandling the consultation period of redundancy is a leading cause of tribunal claims. Common risks include:

• Unfair dismissal claims - where the process isn’t fair or “genuine” consultation hasn’t happened
• Protective awards - for collective redundancy, failure to consult properly can lead to an expensive tribunal-ordered compensation payout
• Civil penalties or criminal prosecution - if you fail to notify the RPS as required
• Damage to morale, reputation, and business relationships

It’s always safest to get expert legal advice on employment law if you’re at all unsure.

What Are The Redundancy Consultation Steps For Employers?

Here’s a step-by-step overview for managing the consultation period of redundancy correctly:

1. Plan your business changes and make a business case
2. Identify employees potentially affected
3. For collective redundancies, notify the RPS and initiate the representative election process (if needed)
4. Send the required written information to employee representatives or directly to individuals (for small-scale redundancies)
5. Start consultation meetings - allow for questions, proposed alternatives, and meaningful discussions
6. Genuinely consider any feedback or alternative solutions
7. Once consultation is complete, confirm your final decision in writing (allow a notice period)
8. Provide redundancy pay and other entitlements correctly
9. Support affected employees (such as with outplacement or reference letters)

Following each of these steps, and documenting them throughout, can protect your business against future disputes or claims.

Can The Consultation Period Be Shortened Or Skipped?

It’s extremely rare for the legal consultation periods to be waived. UK law only allows a very narrow “special circumstances” defence - for example, a sudden company collapse where there’s truly no time to consult. Financial difficulty alone does not usually qualify.

In most cases, even if you're in a hurry to restructure, you must run the full consultation period of redundancy or risk legal consequences.

Other Legal Requirements To Consider With Redundancy

The consultation period of redundancy is just one piece of the legal puzzle. Don’t forget to also:

• Apply fair and objective selection criteria (and document your process)
• Follow all employer obligations under the Employment Rights Act 1996 and Equality Act 2010 (avoid discrimination in your selections)
• Provide the correct notice period and redundancy pay as required
• Issue the final statement of employment and provide all accrued entitlements

What Documents Should You Prepare During Redundancy Consultation?

Having the right paperwork isn’t just good admin - it’s legal protection.

• Written records of all consultation meetings and communications
• Letters to staff setting out reasons and process
• Scripts or checklists for meetings
• Redundancy selection matrices or scoring documents
• Copies of your redundancy policy or staff handbook (if you have one)

Well-drafted documents will help show you followed a fair process if there’s ever a challenge or investigation. For more on essential HR documents, check our guide to staff contracts and employment documentation.
