Your employer has offered you a settlement agreement. Perhaps there has been a redundancy process, a disciplinary matter, or a difficult period that both sides want to draw a line under. The document is usually long, dense with legal language, and comes with a deadline that creates pressure to sign quickly.
Understanding what you are signing matters enormously. A settlement agreement is a legally binding contract that extinguishes your right to bring employment tribunal claims. Once signed and witnessed by an independent solicitor, there is very little you can do to undo it.
This guide explains the clauses you will typically encounter, what they actually mean, and where the negotiating room usually lies.

The legal requirement for independent advice
A settlement agreement is only legally valid if you have received independent legal advice from a qualified adviser — typically a solicitor. This is a statutory requirement under the Employment Rights Act 1996. Your employer will usually offer a contribution toward your legal fees, commonly between £250 and £500, though this does not always cover the full cost of advice on complex agreements.
The independent advice requirement exists because settlement agreements waive significant statutory rights. Parliament recognised that employees should not be able to unknowingly sign away those rights.
The waiver clause — the most important clause in the document
The waiver clause is the centrepiece of any settlement agreement. It specifies which employment claims you are giving up. A typical formulation will list specific claims — unfair dismissal, wrongful dismissal, discrimination claims under the Equality Act 2010, unpaid wages, holiday pay — and often concludes with a broad sweep clause covering "any other claims whether or not known to the parties at the date of this agreement."
You should understand exactly which claims are being waived. The breadth of the waiver is directly relevant to whether the compensation offered is adequate. Waiving a strong unfair dismissal claim for one month's salary is a very different proposition from settling a technical dispute at the end of a long career.
Pay particular attention to whether whistleblowing claims and personal injury claims are excluded from the waiver. They often are — but check.
The payment clause and tax treatment
Settlement agreements typically include a termination payment. The first £30,000 is usually tax-free under section 403 of the Income Tax (Earnings and Pensions) Act 2003, provided the payment is a genuine termination payment and not contractual payments being repackaged. Notice pay and payments in lieu of contractual benefits are taxable regardless of how they are described.
The agreement should clearly break down what each element of the payment represents: notice pay, holiday accrued but untaken, compensation for loss of employment, and any ex gratia element. This breakdown matters for tax purposes and for understanding what you are actually being paid for each thing you are giving up.
The confidentiality clause
Almost every settlement agreement contains a confidentiality clause preventing you from disclosing the fact of the settlement, the amount paid, or the circumstances that led to it. These clauses typically bind both parties — the employer also agrees not to discuss the matter.
The scope of what is confidential matters. Some confidentiality clauses are drafted so broadly that they prevent you from discussing your departure with prospective employers, even in general terms. This is usually not the intention, but it can be the effect of loose drafting. A well-drafted confidentiality clause should carve out: disclosure to your immediate family, disclosure to your legal and financial advisers, and disclosure required by law.
Confidentiality clauses cannot lawfully prevent you from making a protected disclosure — reporting to a regulator, for example, or raising a concern that is in the public interest. Any clause that purports to do so is unenforceable.
The non-disparagement clause
A non-disparagement clause prevents you from making negative statements about your employer, its officers, or its products. These are standard. The question is whether the obligation is mutual — whether the employer is equally prohibited from making disparaging statements about you.
A one-sided non-disparagement clause that binds you but not the employer is worth flagging. If a future employer contacts your former employer and receives a cold or negative response, you have no contractual remedy unless the non-disparagement obligation ran the other way.
The reference clause
Your settlement agreement should specify what reference your employer will provide. A well-drafted reference clause attaches the agreed reference as a schedule to the agreement — so you know exactly what will be said. A clause that simply commits to providing a "satisfactory reference" is vague and difficult to enforce.
The reference clause should also specify who will provide the reference — the HR department, your line manager, or a specific named individual. References provided by different people at the same organisation can vary significantly in tone, even when technically accurate.
Post-termination restrictions
Settlement agreements frequently incorporate or repeat the post-termination restrictions from your original employment contract — non-compete, non-solicitation of clients, non-solicitation of employees. The settlement is an opportunity to negotiate these down or out entirely, particularly if your employer is making a termination payment that implies some acknowledgement of their position.
Courts have confirmed that post-termination restrictions are assessed as at the time of the original contract, not the settlement agreement. However, the settlement agreement is a new contract, and any restrictions included in it will be assessed as of that date — which means restrictions that might have been reasonable when you joined may be harder to justify several years later, in a different role, at a different seniority level.
What to negotiate
The most productive negotiations in settlement agreements typically focus on: the quantum of the payment, the scope of the waiver (particularly any claims that have genuine value), the wording of the agreed reference, the breadth of the confidentiality clause, and the post-termination restrictions. Employers generally expect negotiation. The first offer is rarely the final offer.
Do not sign under time pressure. The Advisory, Conciliation and Arbitration Service (ACAS) Code of Practice recommends a minimum of ten calendar days to consider a settlement agreement. Employers who impose shorter deadlines should be approached with caution, and in some circumstances a compressed deadline may itself be relevant to a claim.
