Job Offer Letter (Kenya)

A Job Offer Letter in Kenya sets out, in writing, the request or notice the sender directs to the recipient.

The Employment Act No. 11 of 2007 replaced the former Employment Act Cap. 226 and brought Kenya's labour law into alignment with the International Labour Organization (ILO) conventions ratified by Kenya, including ILO Convention No. 158 on Termination of Employment and ILO Convention No. 100 on Equal Remuneration. The Act applies to all employees and employers in Kenya — including those in the public sector except where specific sector legislation applies, such as the Public Service Commission Act No. 10 of 2017 for national government employees — and is enforced by the Directorate of Employment and Productivity under the State Department for Labour, and by the Employment and Labour Relations Court (ELRC) established under Article 162(2) of the Constitution of Kenya 2010.

A Job Offer Letter in Kenya is legally significant because it may itself constitute a binding contract of employment if the candidate accepts it and begins work. Under the Law of Contract Act Cap. 23, an offer plus unconditional acceptance plus consideration (the salary and the work to be done) creates a binding legal obligation. Kenyan courts — including the Employment and Labour Relations Court (ELRC) — have consistently held that where a candidate accepts a written Job Offer Letter and relies on it to their detriment (for example, by resigning from previous employment), the employer's withdrawal of the offer may give rise to a claim for damages for breach of contract or promissory estoppel.

The Employment Act No. 11 of 2007 Section 9(1) requires that the contract of service state: the name of the employer, the name of the employee, the date employment commences, the title or grade of work to be performed, the remuneration and method of calculating it, the hours of work, the place of work, the leave entitlement, the notice period required to terminate the contract, and — where the contract is for a fixed term — the duration of the contract. While Section 9 applies to the formal contract of service rather than to the preliminary offer letter, best practice in Kenya aligns the Job Offer Letter with these requirements to prevent subsequent disputes.

The National Social Security Fund Act No. 45 of 2013 (NSSF Act) requires employers to enrol all employees in the NSSF scheme and remit monthly contributions. The National Hospital Insurance Fund Act Cap. 255 (NHIF Act) requires employers to deduct monthly NHIF contributions from employees' salaries. The Job Offer Letter should inform the candidate of these statutory deductions. The Kenya Revenue Authority (KRA) administers PAYE income tax under the Income Tax Act Cap. 470, and the employer is required to deduct and remit PAYE on the employee's gross salary from the first month of employment.

A Job Offer Letter in Kenya is needed at several key stages of the recruitment and employment process, and its preparation and delivery in writing is critical for legal compliance and clarity between employer and employee.

A Job Offer Letter is needed immediately after a candidate has been selected following a competitive recruitment process — whether through internal promotion, external advertisement, executive search, or referral — and the employer wishes to confirm the appointment before the full employment contract is drafted. The letter bridges the gap between the verbal offer extended at the end of the interview and the execution of the formal contract of service under Section 9 of the Employment Act No. 11 of 2007.

A Job Offer Letter is needed when engaging employees subject to conditions precedent — such as satisfactory reference checks, medical fitness clearance from a registered medical practitioner, background verification by the Directorate of Criminal Investigations (DCI), academic certificate verification, or professional licence confirmation (for example, a practising certificate from the Law Society of Kenya or the Institute of Certified Public Accountants of Kenya, ICPAK). The letter sets out these conditions clearly and makes the offer conditional on their satisfaction.

A Job Offer Letter is needed when an employer requires a candidate to give notice to their current employer and needs to provide written confirmation of the offer to support that process. Many employers in Kenya require candidates to resign from current employment before starting, and a formal written offer enables the candidate to manage that process with confidence.

A Job Offer Letter is needed in public sector recruitment governed by the Public Service Commission Act No. 10 of 2017, the County Public Service Boards under the County Governments Act No. 17 of 2012, and the Teachers Service Commission Act No. 20 of 2012, where formal written offers are a mandatory step in the appointment process.

A Job Offer Letter is needed when the employer is a subsidiary or branch of a multinational company operating in Kenya, and the appointment requires approval by a parent company board or human resources department before a full contract can be issued. The offer letter provides the candidate with immediate written confirmation while internal approvals are completed.

A compliant and effective Job Offer Letter in Kenya under the Employment Act No. 11 of 2007 must include the following essential elements.

Employer Details: The full registered name of the employing entity, its physical and postal address, and — for companies registered under the Companies Act No. 17 of 2015 — the company registration number issued by the Business Registration Service (BRS). The letter should be printed on the employer's letterhead and signed by an authorised representative such as the Chief Executive Officer, Human Resources Director, or a person holding a signed authorisation under the company's administrative policies.

Candidate Details: The full name of the candidate as it appears on their national identity card or passport, their current address, and any employee reference or applicant number assigned during the recruitment process.

Position and Department: The exact job title, department or business unit, grade or level (where applicable), and the immediate reporting line (name and title of the candidate's direct supervisor). Where the role is a senior management or director-level position, the letter should state whether the candidate will be a director of the company under the Companies Act No. 17 of 2015 and whether they will be required to file beneficial ownership information with the Business Registration Service (BRS) under the Statute Law (Miscellaneous Amendments) Act 2017.

Start Date and Employment Type: The proposed commencement date of employment; whether the contract is of indefinite duration, a fixed term, or a probationary appointment; and, where a probationary period applies, its duration (typically three to six months as recommended under the Employment Act No. 11 of 2007 and the Employment Regulations 2014). Section 42(1) of the Employment Act No. 11 of 2007 provides that a probationary contract may be terminated by either party on seven days' notice or payment in lieu.

Remuneration Package: The gross monthly salary in Kenya Shillings (KES), itemised to show basic salary, house allowance, transport allowance, and any other emoluments. The letter must state that PAYE income tax under the Income Tax Act Cap. 470, NSSF contributions under the National Social Security Fund Act No. 45 of 2013, and NHIF contributions under the National Hospital Insurance Fund Act Cap. 255 will be deducted from gross salary. Where a performance bonus, commission, or profit-sharing arrangement applies, the basis of calculation and frequency of payment should be stated.

Working Hours and Leave: The normal working hours per day and per week, consistent with Section 27 of the Employment Act No. 11 of 2007 (maximum 52 hours per week including overtime for non-managerial employees). The annual leave entitlement (minimum 21 working days under Section 28 of the Employment Act No. 11 of 2007), sick leave entitlement (minimum 30 days on full pay and 15 days on half pay per year under Section 30), and maternity or paternity leave entitlement (minimum 3 months maternity leave and 2 weeks paternity leave under Sections 29 and 29A respectively) should be stated.

Conditions Precedent: A clear statement of any conditions that must be satisfied before the offer becomes unconditional — including reference checks, medical examination, DCI background check, and certificate verification. The offer must state the timeframe within which conditions must be met and the consequence of non-satisfaction (withdrawal of the offer).

Acceptance Deadline: A specified date by which the candidate must formally accept or decline the offer in writing. Failure to accept within the specified period allows the employer to withdraw the offer and make it to another candidate.

Governing Documents: Reference to the employer's Staff Handbook, Code of Conduct, and other employment policies that will form part of the employment relationship, consistent with Section 9(4) of the Employment Act No. 11 of 2007, which permits terms to be incorporated by reference to documents accessible to the employee.
