Settlement Agreements Explained: What to Know Before You Sign

A settlement agreement (formerly known as a compromise agreement) is a legally binding contract between an employee and employer that settles potential workplace claims. In exchange for a financial payment and sometimes other benefits, the employee agrees not to bring specified claims in a court or tribunal.

Settlement agreements are used in a wide range of situations: redundancy, negotiated exits, resolving grievances, settling ongoing disputes, and ending relationships that have simply broken down. They are a normal part of employment law — receiving one does not mean you have done anything wrong.

From the employer's perspective, a settlement agreement provides certainty: once signed, the employee cannot pursue the claims covered by the agreement. From the employee's perspective, it provides a guaranteed payment and agreed terms without the uncertainty, stress, and delay of tribunal proceedings.

For a settlement agreement to be legally valid and enforceable, several conditions must be met:

• The agreement must be in writing
• It must relate to a particular complaint or proceedings (it cannot be a blanket waiver of unknown future claims)
• The employee must have received independent legal advice from a qualified adviser (typically a solicitor) on the terms and effect of the agreement and its effect on the employee's ability to pursue claims
• The adviser must have a current professional indemnity insurance policy
• The adviser must be identified in the agreement
• The agreement must state that the conditions regulating settlement agreements under the relevant legislation are satisfied

If any of these conditions is not met, the agreement may not be enforceable, and the employee could still bring claims. This is why employers typically pay a contribution towards the employee's legal advice — usually between £350 and £500 plus VAT, though this can be higher for complex cases.

The initial offer is a starting point. In most cases, some or all of the following elements are negotiable:

• The financial payment: This is the most obvious element. Consider what claims you might have, how strong they are, and what a tribunal might award. A strong unfair dismissal claim is worth more than a situation where the employer has followed a fair process.
• Reference: You can negotiate an agreed reference — a specific wording that the employer commits to providing whenever a reference is requested. This is often more valuable than people realise.
• Announcement: How your departure is communicated internally and externally. You may want to agree the wording of any internal announcement.
• Garden leave vs working notice: Whether you continue to work during your notice period, or are placed on garden leave (paid but not required to work).
• Restrictive covenants: If your contract contains non-compete or non-solicitation clauses, you can negotiate their removal or reduction as part of the settlement.
• Legal costs contribution: If the standard contribution does not cover your actual legal costs, you can ask for a higher amount.
• Outplacement support: Some employers will fund career coaching or outplacement services.
• Timing of payments: When the payment is made can affect your tax position and cash flow.

The tax treatment of settlement agreement payments is frequently misunderstood. The key rules are:

First £30,000 tax-free: Genuine termination payments (compensation for loss of employment) are tax-free up to £30,000. This applies to the ex gratia payment in most settlement agreements.

Notice pay is taxed: If you receive a payment in lieu of notice (PILON), this is treated as earnings and is subject to income tax and National Insurance in full. This applies whether your contract has a PILON clause or not — HMRC treats all notice pay as taxable under the "post-employment notice pay" (PENP) rules introduced in 2018.

Other taxable elements: Salary arrears, holiday pay, bonus payments, and benefits continuation are all taxed as normal earnings. They do not count towards the £30,000 exemption.

Payments above £30,000: Any termination payment exceeding £30,000 is subject to income tax (but not employee National Insurance, though employer NIC applies above £30,000).

It is worth structuring the agreement to maximise the tax-free element where legitimately possible. Your solicitor can advise on this.

A COT3 is an alternative form of settlement, brokered through ACAS conciliation. The key differences are:

• A COT3 does not require independent legal advice to be valid — the ACAS conciliator's involvement is sufficient
• A COT3 is typically used when a dispute is already underway (during early conciliation or after a tribunal claim has been filed)
• Settlement agreements are more commonly used for negotiated exits before a formal dispute arises
• Settlement agreements tend to be more detailed, covering matters like references, announcements, and restrictive covenants, whereas COT3s often focus solely on the financial settlement

Both are legally binding, and both prevent the employee from pursuing the covered claims. The choice between them often depends on timing and circumstances rather than a deliberate strategic decision.

• Pressure to sign quickly: You should be given a reasonable period to consider the agreement. The ACAS Code of Practice on Settlement Agreements recommends a minimum of 10 calendar days. If your employer is pushing for an immediate decision, that is a warning sign.
• Overly broad confidentiality clauses: It is normal to include a confidentiality clause, but it should not prevent you from discussing the agreement with your professional advisers, HMRC, or in circumstances required by law.
• Clauses that waive unknown future claims: The agreement should only cover claims that exist or could exist at the date of signing. Be cautious of language that attempts to cover claims you do not yet know about.
• No contribution to legal fees: If the employer refuses to pay towards your legal advice, it may suggest they are not serious about settling or are trying to discourage you from getting proper advice.
• Unreasonable restrictive covenants: Check whether the agreement introduces new restrictions (non-compete, non-solicitation) that were not in your original contract.
• Clawback provisions: Some agreements include provisions allowing the employer to reclaim the payment in certain circumstances. Make sure any clawback is reasonable and clearly defined.

While every situation is different, a typical settlement agreement process follows this approximate timeline:

• Day 1: Employer presents the settlement agreement offer, usually in a "without prejudice" conversation or letter
• Days 1–10: You review the offer, consult a solicitor, and consider your position
• Days 10–14: Your solicitor negotiates amended terms on your behalf
• Days 14–21: Revised agreement circulated, final negotiation on any remaining points
• Days 21–28: Agreement signed, you receive your legal advice certificate
• Termination date: As agreed — could be immediate or at the end of a notice period
• Payment: Usually within 14–28 days of the termination date

The whole process typically takes 2–4 weeks, though complex cases or multi-party negotiations can take longer.
