Navigating workforce changes requires a balance of strategic planning and legal precision. For business owners and HR managers, understanding the intricacies of the redundancy notice period means managing a sensitive transition with professionalism and care.
In this guide, we will navigate the technical and procedural requirements of notice periods within the UK’s legal framework. We will explore the statutory minimums, the complexities of collective consultation, and the financial obligations owed to employees to provide the clarity needed to mitigate the risk of expensive Employment Tribunal claims and protect your organisation’s reputation.
The Strategic Importance of Redundancy Notice
Under the Employment Rights Act 2025, redundancy is a specific form of dismissal that occurs when a business needs to reduce its workforce. The decision is based on the requirements of the role rather than the performance or conduct of the individual.
The Purpose of Redundancy Notice
The notice period serves two primary functions:
- For the Employee: It provides a period of transitional security, allowing time to process the news and begin seeking new employment.
- For the Employer: It ensures an orderly operational handover, allowing the business to manage the redistribution of any work or the phased closure of a site.
The Risks of Non-Compliance
Failing to handle notice periods correctly can lead to significant legal and financial repercussions. It can result in Employment Tribunal claims for:
- Wrongful Dismissal: This occurs if an employer breaches the employment contract, such as by failing to give the employee the full notice period or pay required by the contractual terms.
- Unfair Dismissal: An Employment Tribunal focuses heavily on the “how” of a redundancy. Even if the business case is genuine, a procedural failure, such as skipping consultation or miscalculating notice, can render the dismissal unfair.
Statutory vs. Contractual Notice: Understanding the Baseline
Determining the correct length of the notice period is a fundamental step in ensuring procedural fairness and meeting your financial obligations as an employer. Notice periods are mandated in two different ways: the statutory minimums set by the government and the specific contractual terms agreed upon at the commencement of employment.
Employers must take care to approach these calculations with precision, ensuring that your budget accounts for both statutory entitlements and any enhanced contractual obligations previously agreed with your employees. Providing every “at risk” employee with a clear, written estimate of their notice and statutory redundancy entitlement, in the event they are ultimately made redundant, early in the consultation process is a key component of a “human first” approach that helps manage expectations during an inevitably stressful transition.
Statutory Minimums
The law sets a minimum timeframe for notice periods that employers must respect. These are based on an employee’s length of continuous service:
- 1 Month to 2 Years of Service: At least 1 week of notice.
- 2 Years to 12 Years of Service: 1 week for every full year of continuous service.
- 12+ Years of Service: Capped at 12 weeks of notice.
Contractual Entitlements
Many employment contracts go further than the requirements of statutory redundancy notice periods. For example, a senior manager might have a contractual right to 3 or 6 months’ notice.
- The Rule of Supremacy: If a contract states a shorter notice period than the statutory minimum, the statutory minimum prevails.
- Higher Entitlement: Employers must always provide the higher of the two (statutory or contractual).
Reasonable Notice
If no written contract exists, the principle of “Implied Terms” applies. In such cases, the law implies a requirement for “reasonable notice”. What is considered “reasonable” depends on the employee’s seniority, salary, and length of service, but it can never be less than the statutory minimum.
Collective Consultation: Company Size and Scale
The redundancy process timeline is largely dictated by the number of employees at risk.
Individual Redundancy
For businesses making fewer than 20 employees redundant, there is no statutory minimum timeframe for the overall process. However, employers must still conduct a “meaningful” consultation, which typically takes between 2 to 4 weeks.
Collective Redundancy (20+ Employees)
When 20 or more roles are at risk at one establishment within a 90 day period, strict collective consultation rules apply:
- The 30/45 Day Rule: Consultation must begin at least 30 days before the first dismissal for 20-99 redundancies. For 100+ redundancies, this increases to 45 days.
- The Notice Trigger: Crucially, formal notice of dismissal cannot be issued until the collective consultation phase has been completed.
- Form HR1: Employers must notify the Insolvency Service via an HR1 form. Failing to do so is a criminal offence that can result in unlimited fines.
- Protective Awards: If a Tribunal finds that you failed to consult properly, they can order a “Protective Award”. As of April 2026, this can be up to 180 days’ actual gross pay per affected employee.
When Does Redundancy Notice Start?
The transition from being “at risk” to “under notice” should happen during a formal meeting. This occurs after the consultation phase has concluded and it’s confirmed that no alternatives to redundancy (such as redeployment) have been found.
Notice then generally begins the day after it is communicated to the employee. For notice sent by post, the “clock” typically starts when the employee could reasonably be expected to have received the letter. Using recorded delivery or hand delivering the letter during the final meeting is recommended to avoid disputes over dates.
While oral notice may be legally binding in some contexts, it’s highly risky for employers. Best practice – and often a contractual requirement – is to provide a formal notice of dismissal in writing. This document should clearly state the end date of employment and the details of the redundancy package.
Continuous Service
Employers must be careful when an employee is approaching a service anniversary during the consultation period. If the “statutory notice” would take an employee past their next anniversary of joining, that extra year must be counted toward their statutory notice period and redundancy pay.
Pay and Benefits During the Notice Period
During the redundancy notice period, employees are generally entitled to their usual pay in the normal way if they remain in employment and are working out the notice period.
Aside from basic salary, employees should also continue to receive their contractual benefits, such as company cars, private health insurance, and pension contributions, until the very last day of their notice period, assuming the employee is employed throughout the notice period.
Taxation
It’s important to distinguish between notice pay and redundancy pay for tax purposes:
- Notice Pay: This is subject to standard income tax and National Insurance contributions.
- Redundancy Pay: The first £30,000 of a genuine redundancy payment (including Statutory Redundancy Pay) is typically tax free.
PILON and Garden Leave: Alternatives to Working Notice
If you do not want the employee to work their notice, you may be able to make a payment in lieu of notice (PILON). This is where you terminate the employment immediately and pay the employee for the notice period they would have otherwise worked. The value of this payment will depend on what the contract says on PILON – it may include the value of benefits for the notice period, or be limited to the value of base pay only.
Alternatively, you may decide to invoke a period of Garden Leave, when the employee remains employed and receives full pay but is required to stay away from the workplace and not start a new job. This is often used to protect trade secrets or client relationships by keeping the employee out of the market until their notice expires.
In either case, to avoid a breach of contract, your employment contracts should ideally contain specific PILON and Garden Leave clauses.
Summary Dismissal
If an employee commits an act of gross misconduct during their notice period, the employer may be able to dismiss them summarily without working the remainder notice period or paying the remainder notice pay. In such cases, the employee may also lose their right to Statutory Redundancy Pay.
Employee Rights During the Notice Window
Employees who have been continuously employed for 2 years or more by the time their notice ends have a statutory right to “reasonable” time off during their notice period to look for a new job or arrange training. While the law doesn’t define what is “reasonable”, the employer is only required to pay up to 40% of one week’s pay for this time off.
Additionally, should an employee find a new job and want to start before their notice period ends, they can give “counter notice” to leave early. It’s important to note that employers do not need to agree to this request – and employees may risk their right to SRP if they leave early without the employer’s agreement.
Trial Periods
If an employer offers “suitable alternative employment” to avoid redundancy, the employee is entitled to a 4 week trial period in the new role. If the role proves unsuitable during this time, the employee can still be made redundant and will usually retain their right to redundancy pay based on their original role.
