Settlement Agreements: Should You Accept, Negotiate or Reject?

If your employer has offered you a settlement agreement, the right answer is rarely 'accept the first number'. This guide walks through what these agreements actually are, what the typical terms mean, and how to think about whether the offer is fair.

What is a settlement agreement?

A settlement agreement (formerly called a 'compromise agreement') is a legally binding contract between you and your employer. In return for a payment (and usually other terms), you give up the right to bring specified employment tribunal claims against the employer. The legal basis is section 203 of the Employment Rights Act 1996.

For the agreement to be enforceable, you must receive independent legal advice from a qualified adviser — usually a solicitor, but other categories of adviser also qualify. Your employer typically contributes towards the cost of this advice; that is normal practice, not a favour.

When are settlement agreements offered?

Employers typically offer settlements:

• During or after a redundancy process, to add to or replace the statutory minimum
• After a performance management dispute that has not resolved
• After a grievance or disciplinary process
• When the employment relationship has broken down and both sides want a clean exit
• To pre-empt or settle a tribunal claim (including unfair dismissal or constructive dismissal)

For more background, see the ACAS guide to settlement agreements.

What is usually inside the agreement?

A typical settlement agreement includes:

• A termination payment — often a combination of statutory notice pay, accrued holiday pay, and an additional ex-gratia 'compensation for loss of employment' element
• Tax treatment — the first £30,000 of a genuine compensation payment is usually tax-free; notice pay, accrued holiday and bonuses are taxed as normal. See HMRC on tax on termination payments.
• An agreed reference — a pre-approved factual reference your employer will provide
• A confidentiality clause — you agree not to discuss the terms or the underlying dispute
• A waiver of claims — you waive specified employment tribunal claims (often listed in long form)
• Restrictive covenants — sometimes renewed or relaxed; non-compete and non-solicit terms can be material

How to evaluate an offer

Before accepting, work through:

• What are your claims worth? A strong unfair dismissal or discrimination claim could be worth significantly more than the headline number. The compensatory award for unfair dismissal is statutorily capped; discrimination is not.
• How strong is your case? A weaker case makes the certainty of a settlement more attractive. The lawyer giving you independent advice should help you assess this realistically.
• What are you giving up? Settlement waivers are usually broad — read the list carefully. You are typically giving up all known claims, not only the obvious one.
• Tax — understand which parts of the payment are taxable. PILON (payment in lieu of notice) is always taxable; ex-gratia compensation up to £30,000 usually is not.
• The reference — a good reference can be worth a lot when you are job-hunting. Negotiate the wording, not just the existence.

Can I negotiate? What is usually movable?

Yes — and you usually should. The most commonly negotiated items:

• The headline payment — even if a 'final offer' is described as fixed, employers often have room
• Reference wording — moving from a 'standard reference' to an agreed factual reference is usually low-cost for the employer
• Leaving date — extending the termination date can preserve pension contributions, share vesting, or bonus eligibility
• Notice handling — gardening leave versus PILON has tax consequences
• Restrictive covenants — relaxing non-competes or shortening their length
• Legal fee contribution — many employers will increase this if the agreement is complex

What is taxable and what is not?

Getting this wrong is expensive — many people accept a headline number without realising a large portion is taxable.

• Tax-free (up to £30,000): genuine compensation for loss of employment — the ex-gratia element your employer pays on top of your contractual entitlements
• Taxable as normal earnings: notice pay (whether worked or paid in lieu), accrued holiday pay, contractual bonuses, any payment that mirrors what you were contractually owed
• PILON: payment in lieu of notice is always taxable since April 2018, regardless of how your employer labels it

If your agreement mixes taxable and tax-free elements, the tax treatment should be spelled out clause by clause. If it is not, ask your solicitor to clarify before signing. The HMRC guidance on tax on termination payments is the authoritative reference.

What to negotiate first

Not everything is equally worth fighting for. A rough priority order:

1. The ex-gratia payment — the only element where you have meaningful leverage if your claims are strong
2. Reference wording — negotiate the actual words, not just whether a reference will be given; a poor factual reference can cost more than the settlement is worth
3. Leaving date — extending by days or weeks can preserve pension contributions, share-vesting cliff dates, or a bonus that would otherwise be forfeited
4. Restrictive covenants — post-termination non-competes are only enforceable within certain limits; if yours look broad, ask for them to be narrowed or the period shortened
5. Legal fee contribution — employers routinely increase this when the agreement is complex; ask

The headline payment gets all the attention, but terms 2-5 are often more movable and can have longer-lasting financial consequences.

How long do you have to decide?

There is no statutory minimum time to consider a settlement offer, but ACAS guidance recommends at least 10 calendar days. Employers may say the offer is open for less, but you can request an extension — put that request in writing.

Signing under pressure, without proper time for independent advice, is itself a ground to argue the agreement is invalid. If you are told to sign by the end of the day, say clearly and in writing that you need time to take advice. Keep a copy of everything.

Red flags before you sign

Walk away from, or get further advice on, any agreement that:

• Does not allow you to bring a claim under the Equality Act 2010 for discrimination (waivers must be specific — a blanket "all claims" clause may not be enforceable for future unknown claims)
• Requires you to repay the settlement if you breach a confidentiality clause, without any cap on repayment
• Contains a warranty that you have not already done something that you have in fact done (e.g. spoken to a colleague, retained a document)
• Includes a "COT3" reference without an ACAS conciliation certificate — COT3 agreements have a different legal basis than section 203 settlements
• Imposes non-compete restrictions that would genuinely prevent you from working in your industry for 12 months or more

When to reject

Consider rejecting if:

• The offer is materially below what your claim is worth
• You have strong evidence and are ready for tribunal
• The terms are unreasonable — for example, overly broad restrictive covenants or no agreed reference
• You feel pressured to sign quickly, without proper time for advice (raise this in writing and ask for an extension; that pressure itself is a negotiating point)

Key takeaway

A settlement can be a genuinely good outcome — certainty, a clean break, and money in hand without the stress of a tribunal hearing. But understand what your claim is worth before you accept the first offer. The lawyer giving you the section 203 advice exists to help with exactly this — use them.
