Settlement Agreements Explained — Should You Sign? (2025 Guide)

6 May 2025⏱ 6 min read🇬🇧 England & WalesLast reviewed: May 2025

Thousands of UK workers are offered settlement agreements every year — often with little time to think and pressure to sign quickly. Understanding what a settlement agreement actually is, what you are giving up, and how to assess whether the offer is fair could make a significant difference to the outcome. This plain-English guide covers everything you need to know.

What Is a Settlement Agreement?

A settlement agreement (previously called a compromise agreement) is a legally binding contract between an employer and an employee that settles all claims arising from employment or its termination. In exchange for a financial payment, you agree to waive your rights to bring any claim against your employer in the Employment Tribunal or civil courts. Once signed, the agreement is final — you cannot later change your mind and sue.

Settlement agreements are used in a wide range of situations: on redundancy, following a disciplinary or performance management process, after a grievance, or simply when both sides want a clean break. They are entirely voluntary — your employer cannot force you to sign one, and you cannot be dismissed simply for refusing to engage in settlement discussions (subject to the "protected conversation" rules discussed below).

The Legal Requirements — What Makes It Valid

For a settlement agreement to be legally binding and to effectively prevent you from bringing Employment Tribunal claims, it must meet the strict requirements of section 203 of the Employment Rights Act 1996:

It must be in writing
It must relate to a specific complaint or proceedings (it should list all the claims being settled)
You must have received independent legal advice from a relevant independent adviser — almost always a qualified solicitor — on the terms and effect of the agreement and its impact on your ability to bring tribunal claims
The adviser must be identified in the agreement and must have professional indemnity insurance
The agreement must state that these conditions have been satisfied

The requirement for independent legal advice is not a technicality — it is the cornerstone of the regime. Your employer will usually pay a contribution towards your legal costs (typically £250–£500 plus VAT for straightforward cases). If the contribution offered is inadequate for the complexity of your case, you can ask for more.

Protected Conversations — How Employers Raise Settlement

Section 111A of the Employment Rights Act 1996 (introduced in 2013) allows employers to have "protected conversations" with employees about the possibility of ending the employment relationship on agreed terms. These conversations are "off the record" — they cannot generally be referred to in unfair dismissal proceedings, even if no settlement is reached.

However, the protection has important limits. It does not apply if the employer behaves improperly — for example by applying undue pressure, using threatening language, giving inadequate time to consider, or making the offer in the context of discrimination. It also does not apply to automatic unfair dismissal claims (such as whistleblowing or pregnancy) or to discrimination claims. If the employer behaves improperly, the conversation becomes admissible evidence.

You should be given a minimum of 10 calendar days to consider a settlement agreement before being required to sign — this is the ACAS Code of Practice recommendation. Pressure to sign immediately is a red flag.

What Should a Good Settlement Agreement Include?

When reviewing a settlement agreement, your solicitor will check for the following key elements:

Financial Payment

The headline figure. This typically includes: notice pay (either worked or paid in lieu), accrued but untaken holiday pay, and an ex-gratia payment (a goodwill payment in excess of contractual entitlement). The first £30,000 of a genuine ex-gratia termination payment is usually tax-free under section 403 ITEPA 2003, provided it is not contractual. Notice pay and holiday pay are always subject to tax and National Insurance.

Reference

Always insist on an agreed reference — ideally annexed to the agreement — that the employer commits to providing. Without this, a manager who bears a grudge could give a damaging verbal reference. The agreed reference should cover dates, job title, and a factual or agreed positive statement.

Confidentiality Clause

Most settlement agreements contain a confidentiality clause preventing you from disclosing the terms. These are legitimate, but ensure there are carve-outs for: disclosure to HMRC, disclosure to your immediate family, and disclosure to your legal adviser. You should not be prevented from reporting serious wrongdoing to a regulator.

Non-Disparagement Clause

Prevents you from making negative comments about the employer. Should be mutual — you should not be bound if the employer can say what they like about you.

Claims Being Settled

The agreement will list every possible type of claim you are waiving — unfair dismissal, wrongful dismissal, discrimination, breach of contract, personal injury, etc. Read this list carefully with your solicitor. If there is a claim you want to preserve (for example, a personal injury claim for a known medical condition), it must be explicitly excluded.

Restrictive Covenants

Your contract may already contain post-termination restrictions on working for competitors or soliciting clients. A settlement agreement may seek to reinforce these. Check whether they are enforceable — overly wide restrictions are void as an unreasonable restraint of trade.

Is the Offer Fair? How to Evaluate It

There is no legal formula for what a settlement agreement "should" be worth. It is a commercial negotiation. However, certain factors will influence what is reasonable:

The strength of any tribunal claim — if you have a strong unfair dismissal or discrimination claim, the settlement value should reflect what you might recover at tribunal, discounted for the risk and cost of litigation
Your length of service and salary — longer service and higher salary increase your potential basic and compensatory award at tribunal
How much you want to leave — if you genuinely want to move on, a lower figure may be acceptable for the peace of mind it brings
The reputational and emotional cost of litigation — tribunal proceedings are stressful, time-consuming, and public
Enhanced redundancy pay — if redundancy is involved, check whether the contractual or enhanced redundancy terms exceed statutory minimum, and whether those are included in the figure

Can You Negotiate?

Absolutely — and you should. The first offer is rarely the best offer. Your solicitor can negotiate on your behalf. Common areas for negotiation include: the headline payment, the tax treatment, the reference wording, the scope of the confidentiality clause, the restrictive covenants, and the contribution to legal fees. Employers expect negotiation — making a reasonable counter-proposal does not risk the offer being withdrawn.

Frequently Asked Questions

Do I have to accept a settlement agreement?+

No. Settlement agreements are entirely voluntary. You cannot be forced to sign, and you cannot be dismissed simply for refusing to engage in settlement discussions. However, if your employer has a legitimate reason to end your employment (such as redundancy), they can proceed with the proper process regardless of whether you agree to a settlement.

Is the payment tax-free?+

The first £30,000 of a genuine ex-gratia termination payment is free from Income Tax and National Insurance under section 403 ITEPA 2003. However, any payment that is contractual (such as notice pay or accrued holiday pay) is fully taxable. Post-employment notice pay (PENP) rules introduced in 2018 mean that even PILON payments that were previously tax-free may now be taxable. Your solicitor will advise on the tax treatment of each element.

How long do I have to consider the offer?+

The ACAS Code of Practice recommends at least 10 calendar days to consider a settlement agreement. While this is not legally binding, an employer who applies significant pressure to sign quickly may be behaving improperly, which could undermine the "protected conversation" protections and amount to undue influence.

What if I've already been dismissed — can I still get a settlement agreement?+

Yes. Settlement agreements can be entered into even after employment has ended, to settle claims arising from a dismissal that has already occurred. The time limit for lodging a tribunal claim (three months minus one day) continues to run, so act promptly if you wish to explore settlement after dismissal.
