Secondment Agreement (UK)

A Secondment Agreement in the United Kingdom sets the job duties, pay, hours, leave, and notice terms that bind employer and employee, and is governed by the Employment Rights Act 1996.

Secondments are a well-established feature of UK employment practice. They are used across a wide range of sectors: a law firm may second a solicitor to a major client for six months; a bank may second a risk specialist to a regulatory body; a central government department may second a civil servant to a local authority; a multinational company may second a UK-based manager to an overseas subsidiary. In each case, the legal structure is the same: the home employer retains the employment relationship, the host employer benefits from the employee's services, and a written agreement sets out the terms on which the secondment operates.

The key legal characteristic of a secondment under UK law is that it does not break the employee's continuity of employment with the home employer. This is crucial because many of the most important employment rights — including the right not to be unfairly dismissed, the right to statutory redundancy pay, and the right to request flexible working — depend on continuous employment with a single employer. A secondment that is properly structured maintains this continuity throughout the period of the assignment, regardless of where the employee is physically working or who is directing their day-to-day activities.

The Employment Rights Act 1996 provides the statutory framework within which secondments operate. The Act's provisions on continuity of employment are set out in Part XIV and are largely preserved during an authorised secondment. The employee's statutory rights — including rights to Statutory Sick Pay, Statutory Maternity Pay, and pension auto-enrolment under the Pensions Act 2008 — are also preserved.

From a practical perspective, the secondment agreement needs to address several key issues. First, it must be clear who is responsible for paying the employee's salary and benefits during the secondment. In most cases, the home employer continues to pay the salary and then recharges the cost to the host organisation. In some arrangements, the host employer pays the salary directly, but this is less common because it can create tax complications. Second, the agreement must address the question of supervision and control: the host employer will typically direct the employee's day-to-day work, but the home employer remains responsible for disciplinary matters, performance management, and the employment relationship generally. Third, the agreement must clearly state the employee's right to return to their substantive post at the end of the secondment.

A secondment agreement also needs to address confidentiality carefully. The employee will inevitably be exposed to confidential information belonging to the host organisation during the secondment. The agreement should include strong confidentiality provisions that survive the end of the secondment and prevent the employee from using or disclosing the host's confidential information for the benefit of the home employer or any third party after the secondment ends.

A secondment agreement is needed whenever an employee is to be temporarily assigned to work for a different organisation or a different part of the same group, and the parties wish to preserve the employee's employment relationship with the home employer. The agreement should be signed by all three parties — the home employer, the host organisation, and the employee — before the secondment begins.

The most common scenarios for a secondment agreement in the UK are: client secondments (where a professional services firm assigns one of its staff to a client on a project basis); inter-group secondments (where an employee within a corporate group is moved from one subsidiary to another); public sector secondments (where civil servants, NHS staff, or local government employees are assigned to partner organisations or arm's-length bodies); skills development secondments (where an employer agrees to let an employee spend a period working for a partner organisation to gain skills or experience that will benefit both parties); and regulatory secondments (where a financial services firm seconds an employee to the FCA or PRA as part of a regulatory engagement programme).

The agreement should be prepared well in advance of the secondment start date. Both the home employer and the host organisation need time to review and negotiate the terms, and the employee needs time to understand what they are agreeing to before they sign. In practice, two to four weeks' lead time is normally sufficient, but for complex cross-border secondments (where TUPE, tax residency, or social security coordination may be relevant) more time should be allowed.

If the secondment is likely to extend beyond the originally agreed period, the agreement should be formally varied in writing before the original end date. Allowing a secondment to continue indefinitely without a formal extension can create legal uncertainty about the employee's rights and about the obligations of the home and host employers.

Under the Employment Rights Act 1996, the Employment Tribunal adjudicates workplace disputes. Section 94 of the Employment Rights Act 1996 provides the right not to be unfairly dismissed. The Advisory, Conciliation and Arbitration Service (ACAS) provides early conciliation under Section 18A of the Employment Tribunals Act 1996. The UK GDPR and Data Protection Act 2018 govern personal data handling. HM Revenue and Customs (HMRC) administers PAYE and National Insurance contributions under the Income Tax (Earnings and Pensions) Act 2003.

A well-drafted UK secondment agreement should address the following key elements.

The parties section must identify the home employer (name, address, and company registration number), the host organisation (name, address, and registration number), and the employee (full name and address). Each party should sign the agreement.

The secondment period section should state the start and end dates clearly, and confirm that the secondment is temporary and does not affect the employee's substantive contract of employment. It should also set out the notice required to terminate the secondment early, both by the home employer and by the host organisation.

The role and duties section should describe the work the employee will be carrying out during the secondment, the person at the host organisation to whom they will report, the place of work during the secondment, and the hours of work.

The pay and benefits section should confirm who will pay the employee's salary during the secondment (typically the home employer, with a recharge to the host), what happens if there is a pay review during the secondment, and whether any secondment allowance or uplift will be paid.

The continuity of employment section should confirm that the secondment does not break the employee's continuity of employment with the home employer, and that the employee retains all their existing employment rights throughout the secondment.

The return to work section should confirm the employee's right to return to their substantive post at the home employer at the end of the secondment, or to an equivalent post if the substantive post no longer exists for a reason unconnected with the secondment.

The confidentiality section should impose confidentiality obligations on the employee in relation to the host organisation's confidential information, and should confirm that these obligations survive the end of the secondment.

The intellectual property section should address ownership of any intellectual property created by the employee during the secondment, which will often vest in the host organisation.

The supervision and disciplinary section should confirm that while the host organisation will supervise the employee's day-to-day work, disciplinary matters remain the responsibility of the home employer.
