An employment settlement agreement is a legally binding contract that ends an employment dispute — or the employment relationship itself — on agreed terms. In exchange for a package that usually includes a financial payment, the employee agrees not to bring specified claims against the employer in an employment tribunal or court.
These agreements are now a routine feature of UK workplace exits, from redundancies and performance disputes to senior-level departures. But they are tightly regulated: an employment settlement agreement is only enforceable if strict statutory conditions are met, including independent legal advice for the employee. This guide explains what settlement agreements are, how section 111A of the Employment Rights Act 1996 works, when they are used, how settlement payments are taxed, how to negotiate better terms, and how they differ from an ACAS COT3 settlement.
What Is an Employment Settlement Agreement?
An employment settlement agreement is a written contract between an employer and an employee (or former employee) that settles actual or potential legal claims. The employee typically receives a termination or compensation payment, an agreed reference and sometimes other benefits. In return, the employee waives the right to pursue specified employment claims — most commonly unfair dismissal, discrimination, redundancy pay disputes and breach of contract claims.
Settlement agreements replaced compromise agreements in July 2013. The name changed, but the purpose stayed the same: to give both sides certainty. The employer buys finality — protection against future tribunal claims — while the employee gets a guaranteed package without the cost, delay and stress of litigation.
It is not the same as the contract governing your day-to-day employment. Our guide to contracts of employment explains the terms that apply while you are working; a settlement agreement deals with the end of the relationship and the claims that could follow it.
The Legal Framework: Section 111A ERA 1996 and Protected Conversations
Settlement discussions usually begin with a conversation: the employer proposes terms, and the employee considers them. Section 111A of the Employment Rights Act 1996 makes those pre-termination negotiations inadmissible in an ordinary unfair dismissal claim — if talks break down, the employee generally cannot tell the tribunal what was said.
This protection has limits. It does not cover automatically unfair dismissal (for example, whistleblowing or pregnancy-related dismissals), discrimination, or other claims — and it is lost where there is “improper behaviour” such as bullying, harassment or undue pressure. The ACAS Code recommends giving the employee a reasonable period, generally at least 10 calendar days, to consider the offer.
Where a dispute already exists, talks can also be held on a “without prejudice” basis. Many employers use both labels — “without prejudice and subject to section 111A”. If you are offered an employment settlement agreement after such a conversation, take advice before responding.
When Are Employment Settlement Agreements Used?
An employment settlement agreement can be used in a wide range of situations, including:
- Redundancy exercises, where an enhanced package is offered in return for a clean break
- Performance or conduct disputes, where both sides prefer a negotiated exit to a disciplinary process
- Discrimination or harassment complaints, settled before or after a grievance
- Long-term sickness absence cases, where ill-health capability is in issue
- Senior executive departures, where bonuses, share options and restrictive covenants need careful handling
- Disputes following an alleged breach of employment contract, where the alternative is litigation
What Makes an Employment Settlement Agreement Legally Binding?
Because employees give up valuable statutory rights, Parliament set strict conditions. Under section 203 of the Employment Rights Act 1996, an employment settlement agreement is only valid if:
- It is in writing.
- It relates to the particular complaint or proceedings being settled.
- The employee has received advice from a relevant independent adviser on the terms and effect of the agreement — in particular, its effect on the employee’s ability to pursue claims before an employment tribunal.
- The adviser holds appropriate insurance covering the risk of a claim by the employee.
- The agreement identifies the adviser.
- The agreement states that the conditions regulating settlement agreements have been satisfied.
If any condition is missing, the waiver fails and the employee can still bring tribunal claims — so employers have every incentive to get the paperwork right.
A valid employment settlement agreement also sets out the commercial terms: the compensation payment, notice and holiday pay, the agreed reference wording, confidentiality and non-disparagement obligations, return of company property, and confirmation of post-termination restrictions. Before signing, make sure you understand the employment rights in the UK you are giving up — unfair dismissal and discrimination rights are often the most valuable.
Independent Legal Advice: A Mandatory Requirement
You cannot sign a binding employment settlement agreement without first taking advice from an independent adviser — usually a solicitor, or sometimes a certified trade union official or advice centre worker meeting the statutory criteria. The adviser must be independent of the employer and properly insured.
The adviser’s job is to explain what the agreement means, what claims you are waiving, and whether the deal is fair — not to rubber-stamp it. Employers almost always contribute towards your legal costs, commonly a fixed sum plus VAT; many settlement agreement solicitors offer fixed-fee reviews for exactly this purpose.
Choose your own adviser. The employer may suggest a firm, but the adviser acts for you alone.
Tax on Settlement Payments: The £30,000 Exemption
The headline rule: the first £30,000 of a genuine termination payment can be paid free of income tax under section 401 of the Income Tax (Earnings and Pensions) Act 2003 — but only for payments connected with termination that are not otherwise taxable as earnings.
What falls outside the exemption? Anything that is really wages in disguise: salary arrears, holiday pay, earned bonuses and, since April 2018, the part representing notice pay. Post-employment notice pay is taxed as earnings with National Insurance, and employer National Insurance is due on termination payments above £30,000.
Almost every employment settlement agreement therefore contains a tax indemnity, with the employee reimbursing the employer if HMRC later assesses more tax. Your adviser should explain exactly where the £30,000 line falls in your deal.
Negotiating an Employment Settlement Agreement
An employment settlement agreement is a proposal, not a command — nothing obliges you to accept the first offer. Common negotiating points include:
- The compensation figure — benchmark it against likely tribunal awards plus the employer’s saved legal costs
- The reference — push for agreed wording, not just a promise of a factual reference
- The legal-fee contribution — ask for it to cover the actual cost of advice
- Confidentiality — keep it mutual where possible
- Restrictive covenants — resist attempts to widen non-compete clauses at exit
- The reason for leaving — agreed wording for announcements and future reference requests
Negotiate through your adviser where possible. Settlement agreement lawyers handle these talks daily and will know whether an offer is genuinely competitive.
Can an Employee Request a Settlement Agreement?
Yes. Employers usually make the first move, but nothing stops an employee proposing a settlement — after raising a grievance, for example, or where the relationship has broken down. You can ask for a protected conversation under section 111A to float the idea.
The employer can say no, but raising it can be strategic: it signals seriousness and can accelerate resolution. Take advice first — an employment lawyer experienced in settlement agreements can help you pitch it at the right level and protect your position if talks fail.
Employment Settlement Agreement vs ACAS COT3: Key Differences
The other common route is a COT3 agreement, conciliated through ACAS. The two achieve a similar outcome but work differently:
- Legal advice: a settlement agreement requires independent legal advice; a COT3 does not.
- Who is involved: settlement agreements are private contracts; a COT3 is drawn up with an ACAS conciliator.
- Timing: COT3s are mostly used once a tribunal claim has started or early conciliation is underway; settlement agreements can be used at any stage.
- Formalities: settlement agreements must satisfy the section 203 conditions; a COT3 is valid once agreed through the conciliator.
- Scope: a COT3 is generally tied to the conciliated dispute, while an employment settlement agreement can cover all known and potential claims.
In short, the COT3 is the tribunal-linked route, while the employment settlement agreement is the flexible private route — preferred by employers for pre-emptive exits.
Getting a Job After a Settlement Agreement
In most cases, signing should not harm your career. Settlement agreements commonly include an agreed reference, mutual confidentiality and non-disparagement terms stopping either side from speaking negatively about the other.
Check restrictive covenants before signing: non-compete and non-solicitation clauses from your original contract often survive, and they — not the settlement — are what can limit your next move. Negotiate them down as part of the deal and confirm the agreed reason for leaving.
There is no central register of settlement agreements. With an agreed reference in place, getting a job after a settlement agreement is normally straightforward.
Do You Need a Settlement Agreement Solicitor?
Independent advice is mandatory to make the agreement binding — but good advice usually pays for itself. Settlement agreement solicitors benchmark the offer against likely tribunal awards and spot missing protections, from inadequate references to unaddressed bonuses. As the employer typically funds the advice, the cost to you is often nil.
Unlike the paperwork you signed when hired — our guide to employment agreements covers those — an employment settlement agreement ends rights rather than creating them, so the stakes of getting it wrong are higher.
An employment settlement agreement can be an excellent outcome: a guaranteed package and dignified exit for the employee, certainty and a clean break for the employer — provided the section 203 formalities, tax treatment, reference and waiver scope are right.
Never sign an employment settlement agreement without independent advice, never accept the first offer without question, and never assume the tax position is as simple as the headline figure.
