Settlement agreement

A binding contract to end a workplace dispute — and to give up your right to take it further. Understanding what you are signing, and what the conditions for a valid agreement are, matters before you put pen to paper.

Do I have to sign a settlement agreement?

No. A settlement agreement is voluntary — your employer cannot force you to sign one, and signing under duress may make it unenforceable. You are entitled to take time to consider the offer and take independent legal advice before deciding. The standard ACAS-recommended period is ten calendar days, though employers can offer more time and some offers come with a longer window.

What claims am I giving up when I sign?

Only the claims expressly listed in the agreement. A well-drafted settlement agreement specifies every claim being waived — unfair dismissal, wrongful dismissal, discrimination, unpaid wages, and so on. If a claim is not named, it is not settled, so it is important to read the list carefully. Your independent legal adviser should go through every claim with you and flag any that should be added or removed before you sign.

Does my employer have to pay for my legal advice?

Employers are not legally required to pay, but in practice the vast majority do — often as a condition the employee insists upon. A contribution of £250 to £500 plus VAT is common for straightforward cases, though advice on complex agreements can cost more. Whatever the employer offers, the decision to sign remains yours, and your adviser works for you, not your employer.

Is the settlement payment tax-free?

Payments that are genuinely compensation for loss of employment — as opposed to pay in lieu of notice, holiday pay, or bonuses already owed — can attract the £30,000 exemption under the Income Tax (Earnings and Pensions) Act 2003. Payments above £30,000 are taxable as income. Payments in lieu of notice have been subject to income tax and National Insurance since April 2018 regardless of how they are labelled. Your adviser or an accountant can help you understand the tax position on your specific offer.

What is the difference between a settlement agreement and a COT3?

Both are legally binding, but they are different instruments. A settlement agreement is a private contract between you and your employer, drafted by solicitors and requiring you to take independent legal advice. A COT3 is an agreement brokered through ACAS and recorded on ACAS form COT3 — no independent legal advice requirement, lower costs, and often faster. COT3s typically arise when ACAS early conciliation is already under way. Settlement agreements are more flexible and can cover claims beyond those already notified to ACAS.

Can I negotiate the terms?

Yes. The first offer is rarely final. You and your adviser can push back on the amount, the reference wording, confidentiality obligations, post-termination restrictions, and the scope of claims covered. Common negotiation points include asking the employer to remove non-disparagement clauses that apply only to you, removing or narrowing restrictive covenants, and improving the agreed reference. The fact that your employer has started a settlement conversation does not mean you must accept their initial terms.

What happens if the settlement agreement is invalid?

If the agreement fails to meet one of the statutory conditions — for example, if the adviser was not properly qualified or was not covered by professional indemnity insurance — the waiver of tribunal claims is void. You could then still bring those claims, even if you kept any payment made under the agreement. This is why employers insist on a warranty from your adviser confirming that all conditions have been met.

What a settlement agreement actually is

Most contracts that purport to sign away your employment rights are void. Parliament decided long ago that you cannot simply contract out of statutory protections — the point of those protections is that employees often have unequal bargaining power. But the law has always recognised one legitimate way to settle a real dispute: section 203 of the Employment Rights Act 1996 creates a specific exception, setting out the conditions a written agreement must meet for the waiver to hold.

Until 2013 these agreements were called

compromise agreements

. The name changed to

settlement agreements

under the Enterprise and Regulatory Reform Act 2013, which also introduced the related concept of a protected pre-termination conversation. The substance is the same as before; the rebranding was deliberate — the Government wanted to reduce the stigma of the word "compromise" and encourage earlier settlement.

The core mechanism is straightforward. Your employer offers you money, or some other benefit, in exchange for you agreeing not to bring particular claims. You are released from employment. Your employer is released from legal exposure. Unlike a tribunal judgment, the agreement is private — neither the existence nor the amount has to be disclosed. A typical agreement also contains a confidentiality clause, a non-disparagement clause, and an agreed form of reference, all of which are negotiable.

The critical point is the

independent legal advice requirement

. For the waiver to be effective the agreement must be in writing, must relate to a particular complaint or proceedings, must identify the adviser, and you must have received independent legal advice about its effect on your ability to bring tribunal proceedings. The adviser must be a relevant independent adviser — a solicitor, a barrister, a trade union official with appropriate authorisation, or a workers adviser at a CAB or advice centre — and must be covered by professional indemnity insurance or an equivalent indemnity arrangement. If any of these conditions is not met, the waiver is void even if you have signed and received payment.

The employer typically contributes to the cost of your legal advice. There is no legal requirement to do so, but in practice employees routinely ask for a contribution as part of the negotiation and employers almost always agree, because a valid agreement requires the advice to happen. Contributions of £250 to £500 plus VAT are common for a standard case; more complex agreements attract higher fees, and employers will usually meet a reasonable increase.

A related but distinct concept is the

protected conversation

, introduced by ERA 1996 s.111A at the same time. This allows an employer to approach an employee and make an offer to terminate on agreed terms, and that conversation cannot be used in unfair dismissal proceedings even if no agreement is eventually reached — provided the conversation was not conducted improperly. The protection only covers unfair dismissal; it does not shield offers made in the context of ongoing discrimination, whistle-blowing or automatically unfair dismissal. "Without prejudice" conversations can overlap, but they cover pre-existing disputes rather than a clean opening offer.

. Following a restructure, her manager calls her in, explains that her role is "at risk", and hands her a settlement agreement offering three months gross salary (£9,500) plus a contribution of £500 plus VAT towards her legal advice. She has

Amount above statutory minimum

Maria consults her solicitor, who points out two things. First, the agreement covers "all claims arising from employment or its termination" — a broad waiver that would include an age discrimination claim she had not mentioned to the firm. She had recently been passed over for promotion in favour of a significantly younger colleague and has some evidence suggesting this was age-related. Second, the proposed reference is entirely generic, with no mention of her specific accomplishments.

Her solicitor writes back requesting three changes: the payment to be increased to £14,250 (reflecting the discrimination element), the reference to include two specific sentences about her work, and the removal of a post-termination non-solicitation clause that runs for twelve months. The firm agrees to £12,500, the improved reference, and a six-month restriction instead of twelve.

the initial offer is rarely the final one. The independent legal advice requirement is not a formality — it is the mechanism that identifies leverage and improves the deal.
