Employment Contract Amendment Template for England and Wales

An Employment Contract Amendment, often written as a change of employment contract letter, lets a business formally modify specific terms of an existing employment contract while keeping every other provision intact. Under England and Wales law, this document records the change in enough detail that it is legally enforceable, giving both employer and employee clear written information about what has been agreed.

What is a change of employment contract letter?

It is a short, signed letter or agreement that sits alongside the original contract and states exactly which terms are changing, what the new terms are, and the date they take effect. Because it references the existing contract rather than replacing it, the unchanged clauses continue to apply. This keeps the paperwork simple and helps both sides understand precisely what has and has not changed. If you are hiring rather than amending, start from a full employment contract template instead.

When do you need this document?

You'll need a change of employment contract letter whenever you want to change specific terms of an existing employment contract. Common scenarios include promoting an employee to a new role with different responsibilities, adjusting salary or benefits packages, modifying working hours or patterns, changing workplace locations, updating job titles and reporting structures, or revising leave and holiday entitlement. The document is also useful when implementing company-wide policy changes that affect individual employment terms, such as introducing flexible working arrangements or updating disciplinary procedures. Rather than creating an entirely new contract, this amendment preserves the original agreement while clearly documenting what has changed.

What should the letter contain?

A clear amendment letter covers a consistent set of details so there is no ambiguity later. Include:

• The names of the employer and employee and a reference to the original employment contract by date.
• The specific clause or term being changed and its exact new wording.
• The date the change takes effect.
• Confirmation that all other terms of the original contract remain in full force.
• A statement that the employee agrees to the change, with space for both parties to sign and date.

Setting out this content in plain language helps both sides understand the change and reduces the risk of a later dispute.

A worked example

Say you are promoting Priya Sharma to Senior Account Manager from 1 March. The letter would name the employer and Priya, reference her original contract dated 12 June 2022, and set out the change: "Your job title changes from Account Manager to Senior Account Manager, your annual salary increases from £38,000 to £46,000, and your annual leave entitlement rises from 25 to 28 days. All other terms of your contract dated 12 June 2022 remain in full force." It states the effective date, then gives both parties space to sign. Priya signs to confirm she agrees, and she receives a copy for her records.

Key legal considerations

Under English and Welsh employment law, any material change to employment terms needs the employee's agreement to be legally valid. The letter must clearly identify which specific clauses are being modified and provide the exact new terms. Check that changes comply with statutory minimum requirements, including national minimum wage rates and maximum working time limits. The document must reference the original employment contract and confirm that all unchanged terms remain in effect. Both parties should sign and date the amendment, and the employee must receive a copy for their records. Consider whether the change might constitute a fundamental breach of contract or require consultation, particularly for collective changes affecting several employees or those represented by a trade union.

How do you propose and get an employee to agree to the change?

Explain the reason for the change, share the letter in advance, and give the employee time to read it and ask questions. A short covering note that sets out the proposal, invites a response, and gives a contact for questions helps the employee feel consulted rather than presented with a done deal. For significant or group changes, a short consultation supports agreement and helps everyone understand the impact. Once the employee signs, the change is contractually binding. Keep the signed letter with the original contract so your records show the full history of the employment relationship. You can find related documents in the employment contract template collection.

Requesting, sending and storing the letter

Employees sometimes request a change themselves, for example a shift to reduced or flexible hours. When you receive such a request, respond in writing, and if you agree, record it with this amendment rather than an informal email. Send the letter to the employee ahead of the effective date so they can read it in full before signing. Once signed, store both the original contract and the amendment securely and in line with your privacy obligations, since an employment file holds personal data that must be kept confidential and accessible only to those who need it.

Legal requirements in England and Wales

The Employment Rights Act 1996 requires employers to provide a written statement of any change to employment terms within one month of the change taking effect. Your amendment must comply with the Equality Act 2010, so a change does not discriminate against protected characteristics such as age, gender, or disability. Working Time Regulations 1998 apply when modifying hours or rest periods, while the National Minimum Wage Act 1998 applies to any pay-related change. If you are making collective changes affecting several employees, you may need to follow consultation procedures under the Employment Relations Act 1999, and involve a recognised trade union where one is in place. Write the amendment in clear, understandable language and avoid ambiguous terms that could lead to disputes. Ensure that any changes to disciplinary or grievance procedures comply with the ACAS Code of Practice.
