Employment Compromise Agreements (Settlement Agreements) in the UK

Ending an employment relationship is sometimes the right move for both sides - but if it’s not handled carefully, it can create legal risk, costs and distraction for your business.

That’s where an employment compromise agreement (now commonly called a “settlement agreement” in the UK) can help. Used well, it draws a clean line under disputes, protects your business, and gives the employee certainty.

In this guide, we explain when to use a compromise agreement, the legal requirements for a valid document in the UK, what to include, and a step-by-step process to keep things fair and low-risk. If you’re considering one - whether due to redundancy, performance concerns or a breakdown in the relationship - this is for you.

What Is an Employment Compromise Agreement?

An employment compromise agreement (often called a work settlement agreement) is a legally binding contract in which an employee agrees to waive or settle potential employment claims against your business, usually in exchange for a payment or other agreed terms. They are commonly used to bring employment to an agreed end, but they can also settle disputes where the employee remains employed (less common).

Key points to understand:

• It is a statutory mechanism under UK law allowing employees to waive claims they could otherwise bring (for example, unfair dismissal, discrimination or breach of contract).
• Historically known as “compromise agreements” - most employers, ACAS and advisers now use “settlement agreement,” but both terms refer to the same concept.
• Unlike a simple resignation letter or termination letter, a valid settlement agreement has specific legal requirements (more on these below) so that the waiver of claims actually holds up.

When used appropriately, a compromise agreement gives you finality. In exchange for agreed terms (such as a settlement sum, a reference, and mutual confidentiality), the employee confirms they will not bring listed claims in a tribunal or court.

When Should Employers Use One?

There isn’t a single “best” scenario - compromise agreements are a tool for risk management. Common situations include:

• Redundancy programmes or reorganisations where you want to reduce the risk of later claims and offer a clean break with agreed terms (often above statutory redundancy pay). If you’re considering collective or individual redundancies, it’s wise to combine a fair process with early redundancy advice.
• Performance or conduct concerns where you’re contemplating dismissal but wish to avoid a protracted process or dispute. You might have tried Performance Improvement Plans already, or you’re weighing up the time and risk of continuing performance management.
• Allegations, grievances or breakdowns in working relationships where ongoing employment has become untenable and both sides want certainty.
• Settlement after suspension or disciplinary issues where a negotiated exit is preferable to the risk and distraction of continuing the process. If suspension is on the table, make sure you’re across the employee suspension rules and risks first.
• Avoiding litigation after an internal complaint or a potential claim has arisen - a compromise agreement can settle the dispute confidentially with agreed terms (and a “no admission of liability” clause).

It’s important to emphasise that a settlement agreement should not be used to sidestep a fair process entirely. The best results come when you have a solid paper trail of a reasonable process and a commercially sensible offer.

Legal Requirements For a Valid Agreement (UK)

To be enforceable, a compromise agreement must meet specific statutory requirements. In practice, this is what makes it different from a simple private contract.

Statutory requirements

For most employment claims, the agreement will only be valid if:

• It is in writing.
• It relates to particular proceedings or particular complaints - claims should be clearly identified (often via a schedule of claims).
• The employee has received advice from a relevant independent adviser (such as a qualified solicitor) on the terms and effect of the agreement and, in particular, its effect on their ability to pursue claims.
• The adviser is insured to cover the risk of the advice (professional indemnity insurance).
• The agreement identifies the adviser.
• The agreement states that the statutory conditions regulating settlement agreements are satisfied.

While the Equality Act 2010 and the Employment Rights Act 1996 sit in the background here, the key takeaway is simple: without independent legal advice for the employee and the right form of words, the waiver of claims will not be effective.

Without prejudice and “protected conversations”

You’ll often hear employers talk about “without prejudice” discussions when exploring a settlement. In broad terms, genuine dispute settlement discussions are privileged and cannot be used as evidence if negotiations break down. Separately, the Employment Rights Act 1996 (s.111A) allows for “pre-termination negotiations” (sometimes called protected conversations) that cannot be referred to in an ordinary unfair dismissal claim, even where there is no existing dispute.

These protections are not absolute - for example, they don’t cover claims of discrimination or automatic unfair dismissal. If in doubt, get advice before you open the conversation.

ACAS COT3 alternative

As an alternative to a private settlement agreement, you can settle via ACAS using a COT3. This is a simple, ACAS-brokered form that can be especially useful once a tribunal claim has been issued. Many employers still prefer a comprehensive settlement agreement because it allows broader protections (confidentiality, post-termination restrictions, IP and property return, etc.).

Tax treatment basics

Tax is a critical part of structuring any compromise agreement:

• Contractual earnings - salary, accrued holiday pay, bonuses and payments in lieu of notice (PILON) are taxable and subject to usual deductions (PAYE and NICs).
• Ex gratia termination payments - subject to the £30,000 income tax exemption (above that, tax applies). Employee NICs generally do not apply to ex gratia sums, but employer NICs may be due on certain elements.
• Warranties often require the employee to indemnify you if HMRC later determines that more tax was due (for example, if a sum labelled “ex gratia” is actually earnings).

Tax treatment is fact-specific - mislabelling payments can create unexpected liabilities - so get tailored advice as you structure the package.

What To Include In Your Work Settlement Agreement

Every business and situation is different, but most compromise agreements will cover the following:

1) Termination mechanics and payments

• Termination date and whether there will be a working notice period or a PILON.
• Settlement sum (ex gratia) and when it will be paid, with tax wording and any gross-up provisions where needed.
• Accrued entitlements such as salary, holiday pay and any commission or bonus pay due under contract.
• Deductions permitted from the final pay (ensure they are lawful - see wage deductions).

2) Waiver of claims

• A clear waiver of specified claims (usually with a schedule listing common statutory and contractual claims).
• Preserved rights that cannot be waived (for example, accrued pension rights, personal injury claims unknown at the date, and whistleblowing).

3) Confidentiality and non-disparagement

• Mutual confidentiality around the dispute, terms and amounts, subject to typical carve-outs (legal advisers, immediate family, tax authorities).
• Mutual non-disparagement clauses to protect your business’ reputation and the employee’s.

4) Company property and information

• Return of devices, keys, documents and data (including certification that all company data has been deleted from personal devices and cloud stores).
• Ongoing confidentiality obligations regarding trade secrets and business information.

5) Post-termination restrictions

• Reaffirmation of existing restrictive covenants (non-compete, non-solicitation, non-poaching). If you’re updating restrictions, make sure they’re reasonable in scope and duration - see our guide to 12-month non-compete clauses.

6) References and announcements

• Agreed reference wording (annexed or set out in the agreement), and who can give it.
• Internal and external announcements about the departure.

7) Warranties and repayments

• Employee warranties that they haven’t already taken new employment, they haven’t breached obligations, and they haven’t hidden misconduct or expenses.
• Repayment provisions for loans, equipment, or amounts owed under any repayment of training costs clauses (ensure the clause is enforceable and proportionate).

8) Adviser certificate

• The independent legal adviser’s certificate confirming advice has been given, the adviser is insured, and the statutory conditions are satisfied.

Well-drafted terms work hand-in-hand with your underlying documents. Having a clear Employment Contract and policies (for example, confidentiality and disciplinary policies) gives you leverage and clarity when negotiating the agreement.

How To Run a Fair, Low-Risk Process

A thoughtful process reduces the risk of a claim and makes it more likely the employee will sign quickly. Here’s a practical structure that works for most UK employers.

1) Sense-check your reason and paperwork

Start by asking: is a settlement agreement the right tool here? For example, if you’re dealing with gross misconduct, you may need a careful disciplinary process or even a summary dismissal rather than a settlement approach. If it’s performance-related, consider whether a fair PIP has been run and documented. If you’re restructuring, ensure your redundancy rationale and selection criteria are defensible.

2) Plan your conversation and label it properly

Decide whether to rely on “without prejudice” (where a dispute already exists) or a protected conversation (s.111A ERA) for ordinary unfair dismissal risk. Avoid any language that could be seen as discriminatory or improper behaviour (which would strip away protections). Keep the tone professional and constructive.

3) Present the offer in writing

Provide a short offer letter outlining the key commercial terms (sum, termination date, reference, confidentiality) and an expiry date. Then issue the draft settlement agreement. Give a reasonable period for consideration - 10 calendar days is commonly recommended in ACAS guidance.

4) Facilitate independent legal advice

It’s standard to contribute to the employee’s legal fees for advice on the agreement. This doesn’t control their advice - it simply ensures the statutory requirement is met. Typical caps vary depending on seniority and complexity.

5) Negotiate and finalise

Expect some negotiation on the financials, reference wording and restrictions. Keep your red lines clear and link improvements to meaningful protections for your business (for example, strengthening confidentiality or reaffirming covenants).

6) Execute and complete handover

Once signed by both parties and the adviser’s certificate is attached, pay on time and complete the practical steps: revoke system access, collect property, complete payroll, and align your HR file. If appropriate, follow your ending an employment contract checklist to tidy up loose ends.

7) Keep your wider compliance on track

If the settlement follows a period of suspension, disciplinary action or absence, ensure your files show you followed a fair process and your working time and break obligations were met during the employment. Good hygiene across your HR processes helps defend your position if anything is later challenged.

Common Mistakes To Avoid

• Rushing the conversation without planning whether to rely on protected conversations or without prejudice rules.
• Using generic templates that don’t reflect your business, the employee’s contract, or the real risks at stake - bespoke drafting matters.
• Missing claims in the waiver schedule or using wording that’s too broad to be enforceable.
• Overreaching restrictions (e.g., a non-compete that’s too long or too wide geographically) that could be unenforceable - tailor them or reaffirm existing, reasonable covenants.
• Confusing tax treatment by labelling earnings as ex gratia (or vice versa) and creating unexpected PAYE/NIC liabilities.
• Insufficient consideration period - pressuring an employee to sign quickly can backfire and may be used as evidence of improper behaviour.
• Not closing operational risks - forgetting to revoke access, retrieve data or formalise the agreed reference.

How Settlement Agreements Fit With Other HR Processes

Compromise agreements don’t replace fair processes - they complement them. You still need robust contracts, policies and documented steps when managing performance, conduct and exits. For example, align your approach with your Employment Contract terms on notice, PILON and confidentiality; use warnings appropriately (see final written warnings); and consider whether suspension or dismissal is justified before you pivot to settlement.

If the relationship has broken down, a well-judged settlement can be the fastest, fairest way to move forward for everyone - and it protects your business against open-ended employment tribunal risk.

Key Takeaways

• An employment compromise agreement (settlement agreement) is a powerful risk-management tool to end employment on agreed terms and settle potential claims.
• For validity, it must be in writing, specify the claims being waived, and the employee must receive advice from an insured, independent legal adviser who is identified in the agreement.
• Structure the package correctly: notice pay and contractual earnings are taxable; ex gratia termination payments benefit from the £30,000 income tax exemption subject to specific rules.
• Include core protections: waiver of claims, confidentiality, non-disparagement, return of property, reaffirmation of reasonable post-termination restrictions, agreed reference wording, and appropriate warranties.
• Run a fair process: plan your conversation (protected/without prejudice), give a reasonable consideration period, contribute to legal fees, and complete a thorough handover on exit.
• Don’t rely on generic templates - tailor the agreement to your employee’s Employment Contract, your processes and the risks in play, and sense-check related issues like summary dismissal, redundancy and non-compete clauses.
