Receiving a settlement agreement (formerly known as a compromise agreement) can be a whirlwind of emotions. Whether it follows a period of redundancy, a workplace dispute, or a mutual decision to part ways, the document in front of you is more than just a "severance package." It is a legally binding contract that terminates your employment and, more importantly, waives your right to bring any future legal claims against your employer.
In the UK, the law recognizes the gravity of this decision. This is why a settlement agreement is only legally valid if you have received advice from an independent settlement agreement solicitor UK.
At Tyndel Solicitors, we often see employees who are so eager to "move on" that they overlook critical details that could cost them thousands of pounds or impact their future careers. To ensure you exit your role with the best possible protection, here are the seven most common mistakes you need to avoid before putting pen to paper.
1. Failing to Negotiate the Reference
Many employees focus entirely on the "headline figure": the total amount of money being offered. While the financial compensation is vital, your future employability is worth even more.
A common mistake is assuming that your employer will automatically provide a positive or even a "standard" reference. In the UK, there is generally no legal obligation for an employer to provide a reference at all, and if they do, it only needs to be "true, accurate, and fair."
When working with a settlement agreement solicitor UK, you should ensure that a specific, agreed-upon reference is attached as a schedule to the agreement. This ensures that:
- The wording is fixed and cannot be changed later.
- Prospective employers receive exactly what was promised.
- You avoid the risk of a "standard" reference (dates and job title only) which can sometimes look suspicious to new recruiters.
2. Misunderstanding the Tax Implications
One of the biggest misconceptions in employment law is that the first £30,000 of any settlement is always tax-free. This is not strictly true.

While "ex-gratia" payments (compensation for loss of office) up to £30,000 can often be paid without tax or National Insurance deductions, other elements of your package are fully taxable. These include:
- PILON (Payment in Lieu of Notice): Following the "Post-Employment Notice Pay" (PENP) rules, notice pay is almost always subject to tax and National Insurance.
- Holiday Pay: Any payment for accrued but untaken holiday is treated as earnings and taxed accordingly.
- Bonuses and Commission: Contractual bonuses are generally taxable.
Mistaking taxable income for tax-free compensation can lead to a nasty surprise from HMRC later. A specialist solicitor will help you break down the payments to ensure the tax treatment is compliant and that you aren't overpaying. You can find more details on current employment regulations in our guide to the Employment Rights Act.
3. Overlooking Pension Contributions
Pension rights are among the most valuable assets an employee has, yet they are frequently ignored during settlement negotiations.
There are two main pitfalls here:
- Accrued Rights: You should ensure the agreement expressly states that you are not waiving your accrued pension rights. These are yours, and the settlement should not interfere with them.
- Loss of Future Contributions: If you are leaving your job mid-month or under a PILON arrangement, you may be missing out on employer pension contributions that would have been made during your notice period.
Ask your employer to include a sum that compensates you for the loss of these contributions. If you are in a final salary or defined benefit scheme, the loss can be significant, and you may need actuarial advice to calculate the true cost of your exit.
4. Accepting the First Offer Without Question
Psychologically, employers often present a settlement agreement as a "take it or leave it" final offer. In reality, it is usually just the starting point of a negotiation.

Employers offer settlement agreements because they want "certainty." They want to know that you won't take them to an employment tribunal for unfair dismissal or discrimination. That certainty has a price.
An experienced settlement agreement solicitor UK will evaluate the strength of your potential legal claims. If you have a strong case for unfair dismissal, the employer should pay more to settle. Don't be afraid to ask for more: whether that’s a higher ex-gratia payment, a longer period of benefits (like private medical insurance), or an extension of your notice period.
5. Ignoring Post-Termination Restrictions
Also known as "Restrictive Covenants," these clauses can prevent you from working for a competitor, poaching clients, or even hiring former colleagues for a set period (usually 3, 6, or 12 months) after you leave.

A mistake many make is signing the agreement without realizing these restrictions are being reaffirmed or even introduced for the first time. If you have a new job lined up, these clauses could literally prevent you from starting your next role.
You should negotiate to have these restrictions shortened or removed entirely as part of your exit deal. If the employer wants you to sign away your rights, they should be willing to release you from restrictions that hinder your future career.

6. Forgetting the Legal Fee Contribution
By law, you must receive independent legal advice for a settlement agreement to be valid. Because of this, it is standard practice for the employer to pay a contribution towards your legal fees.
However, many "standard" contributions (often £350 to £500 plus VAT) may not cover the full cost of a comprehensive review and negotiation. If the agreement is complex or if you want your solicitor to negotiate a better deal on your behalf, you should request that the employer increases their contribution to cover the actual costs.
At Tyndel Solicitors, we strive to ensure our fees are transparent and, where possible, covered by the employer's contribution so that you are not left out of pocket for seeking professional advice.
7. Signing Without a Specialist Solicitor
Perhaps the most dangerous mistake is treating the legal review as a "box-ticking" exercise. Not all solicitors have the same level of expertise in employment law.
A generalist solicitor might miss the nuances of a non-derogatory clause (which prevents either party from "trashing" the other’s reputation) or fail to spot a "clawback" clause that allows the employer to demand their money back if you breach a minor term of the agreement.
You need a supportive, professional partner who understands the London and UK employment market. You need someone who can spot the hidden traps and fight for the package you deserve.
