Notice Of Severance In The UK: When To Use It And What To Include

If you’re running a small business, ending an employment relationship is one of those tasks that can feel high-stakes - even when everyone is acting reasonably.

A clear written notice confirming termination and any severance terms (sometimes called a severance notice letter) can help you communicate what’s happening, reduce misunderstandings, and keep a clean paper trail for your HR records.

In this guide, we’ll walk you through when you might use a notice of severance, what to include, and how to approach a notice of severance template UK style document so it actually protects your business (rather than creating new risk).

Quick note: “Severance” can overlap with redundancy, settlement discussions, or dismissals for conduct/capability. The “right” wording depends heavily on the reason for the exit - so treat templates as a starting point, not a one-size-fits-all fix.

What Is A Notice Of Severance (And Is It A Legal Requirement)?

A “notice of severance” isn’t a standard legal term in the UK, but businesses often use it to describe a written letter confirming that employment is ending and setting out the practical and payment arrangements. Typically, it covers:

• the termination date
• the notice being given (or payment in lieu of notice)
• what will be paid (final salary, holiday pay, any severance/ex gratia amount, etc.)
• practical handover steps (return of property, access removal, etc.)

UK law doesn’t require you to issue a document specifically called a “notice of severance”. However, you do need to comply with legal and contractual requirements when ending employment, such as giving the correct notice (unless summary dismissal for gross misconduct is lawfully justified) and paying all sums due (including accrued holiday). In practice, many employers confirm the key points in writing to avoid disputes.

Most employers use a written notice because it:

• reduces “he said/she said” disputes about what was agreed
• helps show what process was followed (especially where dismissal is contentious)
• confirms the financial position and avoids follow-up confusion
• creates a clear internal record if there’s later a grievance, ACAS process, or tribunal claim

From a practical perspective, it’s also a professional way to wrap up the employment relationship - which matters if you’re trying to keep goodwill (for example, when offering an enhanced severance amount or discussing a reference).

When Should Employers Use A Notice Of Severance?

You’ll usually issue a notice of severance (or a termination/severance letter) when you have decided the employment is ending and you want to confirm the key details in writing.

Common situations include:

1) Redundancy (Or Restructure)

If the role is genuinely no longer required, or your business is restructuring, you may be starting a redundancy process and later confirming the outcome in writing.

In those cases, your letter should match what has happened in the redundancy process and should accurately set out notice and any redundancy-related payments. If you’re weighing up the difference between “severance” and “redundancy”, it’s worth being really clear internally about what you’re offering and why (and how it’s being described). This is where the distinction in Severance vs Redundancy becomes important.

Redundancy exits also commonly involve minimum notice obligations - you can sense-check those in Redundancy Notice Periods.

2) Mutual Separation (Agreed Exit)

Sometimes a role isn’t working out, but both sides would rather agree on an exit than run a formal performance or disciplinary process. In these situations, employers may offer an enhanced payment as part of a clean break.

If you’re going down this path, be careful: if you’re expecting the employee to waive claims, you’ll generally need a properly drafted settlement agreement (with independent legal advice for the employee) rather than relying on a simple letter.

That said, a notice of severance can still play a role in documenting the agreed end date and what will be paid (and when), alongside a more formal agreement. Mutual exits are often handled using Mutual Termination Agreements principles, even if the paperwork is packaged differently.

3) Capability Or Performance Exits

If an employee can’t perform the role to the required standard (after a fair process), termination might be on capability grounds. In practice, many small businesses start with structured performance management, which can include Performance Improvement Plans.

Where you terminate after a capability process, the severance/termination notice letter should be consistent with the steps you’ve followed, the reasons given, and any right of appeal you offer.

4) Conduct Issues (Including Gross Misconduct)

Where conduct is the issue, your approach depends on severity. For gross misconduct, employers sometimes use summary dismissal (no notice pay), but this is an area where getting it wrong can be expensive.

If you’re considering dismissal for gross misconduct, use a checklist approach and keep your process clean - the Gross Misconduct Checklist is a helpful reference point for what “good process” typically looks like.

Even when you dismiss summarily, you’ll usually still confirm the decision in writing, along with final pay details (and any accrued holiday).

5) Using Payment In Lieu Of Notice (PILON)

Sometimes you want the employee to leave immediately (for operational, customer, or confidentiality reasons), but you still want to meet notice obligations by paying instead of having them work the notice period.

In that case, your notice of severance should clearly state that you’re making a payment in lieu of notice, how it’s calculated, and when it will be paid. PILON can be straightforward in concept, but it needs to be handled correctly in the contract and in the letter - PILON rules and drafting can matter more than employers expect.

What Should A Notice Of Severance Include? (Employer Checklist)

If you’re searching for a notice of severance template UK, what you’re really looking for is a reliable structure - the set of clauses and information that should almost always be there, plus the “optional extras” depending on the exit type.

Here’s a practical checklist from an employer perspective.

Core Details (Almost Always Needed)

• Employee details: full name, address (if you include it), job title, and employee number (optional).
• Employer details: legal entity name and registered address (especially important if you trade under a business name).
• Date of the letter and how it will be delivered (email + hard copy, if relevant).
• Termination date: the “effective date of termination” (EDT). This date can matter for statutory rights, holiday, and limitation periods.
• Notice being given: confirm whether the employee will work their notice or whether you are paying in lieu.
• Final salary arrangements: what will be paid up to the termination date and when payroll will process it.
• Accrued but untaken holiday: whether you require it to be taken during notice (if working notice) or paid out.
• Deductions: confirm that normal tax/NI will be deducted, and set expectations for any other lawful deductions (only where permitted).

Payment Terms (Be Specific - This Is Where Disputes Start)

If you’re offering a severance amount (whether contractual or discretionary), clarity is everything. Your notice should set out:

• Severance amount: the gross figure and whether it’s contractual or discretionary (and any conditions).
• What it includes: e.g. does it include notice pay, holiday, bonus, commission, allowances?
• Payment date: on the next payroll run, within X days, or on completion of a settlement agreement.
• Tax position: don’t give tax advice, but do state that payments will be processed in line with PAYE requirements and applicable law.

Tip: If you’re using severance as part of a deal to end employment on agreed terms, don’t accidentally create a “binding settlement” via a poorly worded letter. This is one of the biggest risks with a DIY notice of severance template UK document.

Reason For Termination (Choose Your Words Carefully)

Some employers want to keep the letter “neutral” and just confirm the end date. Others need to document the reason (redundancy, capability, conduct, etc.) in a way that aligns with the process followed.

There isn’t a single right answer - but there is a wrong one: including inconsistent or unclear reasons that contradict your process, meeting notes, or internal communications.

As a general guide:

• Redundancy: state redundancy and reference the consultation process you followed.
• Capability/performance: reference the capability process and any meetings/warnings (without writing an essay).
• Conduct/gross misconduct: confirm the outcome of the disciplinary process and whether dismissal is with notice or summary.

Right Of Appeal (Often A Smart Risk-Management Step)

Even for small businesses, offering a right of appeal is often sensible, especially where dismissal could be challenged as unfair. Your letter can state:

• the deadline to appeal (e.g. within 5 working days)
• who the appeal should be sent to
• what the appeal should include (grounds, supporting info)

Confidentiality, Restrictive Covenants, And Company Property

Your notice of severance should usually remind the employee of ongoing obligations, including:

• Confidentiality: duties in the employment contract, and any separate NDA.
• Restrictive covenants: non-solicitation, non-dealing, non-compete clauses (where you have them).
• Return of property: laptops, keys, passes, uniform, documents, and anything holding customer or business data.
• IT access: when accounts will be disabled (and what monitoring/handovers are required).

This is also a good moment to sense-check whether your Employment Contract is doing enough heavy lifting on confidentiality, notice, and post-termination restrictions - because your exit letter should support the contract, not replace it.

References (Optional, But Useful To Clarify)

If you’re willing to provide a reference, you can state what form it will take (e.g. factual only, confirming title and dates). If you aren’t, it’s often best to say nothing in the notice and deal with any request separately to avoid accidental commitments.

Data Protection And Record-Keeping

Termination involves personal data (pay, performance notes, disciplinary records, health information in some cases). Make sure you handle this in line with the UK GDPR and the Data Protection Act 2018:

• limit access to the information internally
• keep only what you need, for as long as you need it
• store it securely

Your severance notice doesn’t need a long “data protection clause”, but it should avoid oversharing sensitive details (especially if you’re sending it by email) and should be written with the expectation it could be read by a third party later.

Notice Of Severance Template UK: A Practical Structure You Can Adapt

If you’re looking for a notice of severance template UK, this structure is a safe starting point for many common scenarios. You’ll still want to tailor it to the reason for termination, the contract terms, and the process you’ve followed.

1) Heading And Parties

• Private & Confidential
• Date
• Employee name
• Employee address (optional)

2) Opening Statement

Confirm the purpose of the letter clearly and calmly (e.g. “This letter confirms the termination of your employment with .”).

3) Termination Date And Notice

• State the effective date of termination.
• State the notice period and whether it will be worked or paid in lieu.
• If worked: confirm expectations during notice (duties, handover, holiday instructions).
• If PILON: confirm the payment approach and timing.

4) Final Payments

• Final salary up to termination date
• Holiday pay (accrued but untaken)
• Any contractual entitlements (commission/bonus only if clearly due)
• Any severance/ex gratia payment (including conditions, if any)

5) Practical Exit Steps

• Return of company property by a specific date
• Handover requirements (clients, projects, passwords, documentation)
• Confirmation of final day access to premises/systems (as relevant)

6) Post-Termination Obligations

• Confidentiality reminder
• Restrictive covenants reminder (if applicable)
• Non-disparagement wording (only where appropriate and carefully drafted)

7) Appeal (If Applicable)

• How to appeal
• Deadline
• Who it should be addressed to

8) Closing

End professionally. If the departure is amicable, you can thank them for their contribution (without making statements that conflict with the reason for termination).

Practical tip: If you’re unsure whether your letter should be framed as a “termination letter” or a “severance notice”, start with clarity on the legal basis for ending employment and make sure the letter reflects (rather than replaces) the process you’ve followed. Often, the safest route is to use a properly drafted Termination Letter format and then include severance payment terms where relevant.

Common Mistakes With Severance Notices (And How To Avoid Them)

A template can be helpful - but severance notices commonly go wrong in predictable ways. Here are the issues we see most often with small businesses.

1) Mixing Up Redundancy Pay, Notice Pay, And Severance

“Severance” is often used casually to mean “some money to help the employee move on”. But legally and practically, you need to separate:

• Notice pay (contractual and/or statutory)
• Holiday pay (accrued entitlement)
• Redundancy pay (where redundancy applies and eligibility is met)
• Ex gratia/enhanced severance (discretionary, typically offered as part of an agreed exit)

If your letter bundles these into one vague figure, you increase the chance of disputes and accidental admissions.

2) Promising Things You Don’t Actually Intend To Give

Be cautious about wording like “we will provide a reference” or “you will receive your bonus” unless you’re 100% sure. If it’s discretionary, say so. If it’s conditional, state the condition.

3) Summary Dismissal Without A Safe Basis

Withholding notice pay is a big step and usually hinges on whether the employee’s conduct amounted to gross misconduct and whether you followed a fair process.

Even if you believe summary dismissal is justified, your letter should be consistent with the investigation and disciplinary outcome.

4) Forgetting Contract Terms (Or Contradicting Them)

Your notice of severance should match the employment contract, especially around:

• notice length
• PILON clauses
• garden leave rights
• post-termination restrictions

If your contract is silent or unclear, your risk goes up - because the employee may argue a different interpretation of their entitlements.

5) Trying To “Settle” Claims Without A Settlement Agreement

If you’re offering money in exchange for the employee agreeing not to bring claims, a basic severance notice usually isn’t enough to achieve that legally.

In the UK, an employee typically can’t waive statutory employment claims (like unfair dismissal or discrimination claims) just by signing a simple letter - there are formal requirements for a settlement agreement. So if “clean break” is the goal, it’s worth getting proper advice before you send anything.

Key Takeaways

• A notice of severance isn’t a magic legal label, but a clear written notice can reduce disputes and help you manage employment exits professionally.
• Your notice should clearly state the termination date, notice arrangements (worked notice vs PILON), and exactly what will be paid and when.
• If you’re searching for a notice of severance template UK document, focus on a structure you can tailor - templates that ignore the reason for termination can create legal risk.
• Be careful not to mix up severance, redundancy pay, notice pay, and holiday pay - these are different concepts and should be set out clearly.
• If your goal is a full “waiver of claims”, you’ll usually need a properly drafted settlement agreement, not just a severance notice letter.
• Always make sure your severance notice aligns with the employment contract and the process you’ve followed (capability, conduct, redundancy, etc.).
