Appointment Letter (UK)

An Appointment Letter in the United Kingdom is a legally binding written instrument.

The Employment Rights Act 1996 (ERA 1996) is the primary statutory source of obligations relating to written employment terms in Great Britain. Section 1 of the ERA 1996 requires employers to provide employees with a written statement of the particulars of their employment, and since 6 April 2020 (following amendments made by the Employment Act 2002 and the Employment Rights (Employment Particulars and Paid Annual Leave) (Amendment) Regulations 2018, as part of the Good Work Plan legislation), this statement must be provided on or before the first day of employment. The requirement was extended to workers (not just employees) from the same date. A failure to provide the written statement entitles the employee to complain to an employment tribunal, and if the employee brings a successful claim on another matter at the same time, the tribunal may award an additional two to four weeks' pay.

The ERA 1996 distinguishes between a principal written statement (which must be a single document and include the core particulars) and supplementary particulars (which may be provided in separate documents). The principal written statement must include the employer's name, the employee's name, the start date, the date continuous employment began, pay rate and intervals, working hours, holiday entitlement, job title, and place of work. These core terms are typically included in the appointment letter itself, making the letter the principal written statement.

The National Minimum Wage Act 1998 and the National Minimum Wage Regulations 2015 require that the pay rate stated in an appointment letter must equal or exceed the applicable National Minimum Wage or National Living Wage rate. From April 2024, the National Living Wage for workers aged 21 and over is £11.44 per hour. HMRC enforces compliance through routine checks and in response to worker complaints, and naming and shaming employers who fail to pay minimum wage is an HMRC enforcement option.

The Equality Act 2010 prohibits discrimination in the recruitment process. An appointment letter must not contain terms that differ from those offered to comparable employees on grounds of a protected characteristic (age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, or sexual orientation). An employer who withdraws a job offer for a reason connected to a protected characteristic may face a discrimination claim in the Employment Tribunal.

A UK Appointment Letter is needed every time an employer in England, Wales, or Scotland offers a position to a candidate and wishes to set out the terms of the appointment in writing before the employee starts work.

The appointment letter is needed for all employees — whether full-time, part-time, fixed-term, or temporary — from the date of acceptance. Since 6 April 2020, employers must provide written particulars of employment on or before day one; the appointment letter issued at the offer stage is the most practical way to meet this obligation early.

Small businesses hiring their first employee need an appointment letter to create a clear contractual record of the terms agreed. Without a written record, disputes about salary, notice period, or working hours are difficult to resolve and leave the employer exposed to Employment Tribunal claims based on unwritten terms.

Employers hiring for roles that involve access to confidential information, clients, or commercial secrets need an appointment letter that incorporates confidentiality obligations and, if appropriate, post-termination restrictions. These restrictions must be proportionate and no wider than necessary to protect the employer's legitimate business interests — a principle confirmed by the High Court in Beckett Investment Management Group Ltd v Hall [2007] EWCA Civ 613.

Recruitment involving overseas nationals who require a visa to work in the UK creates a specific need for an appointment letter confirming the role and salary, which the applicant may need to submit to the Home Office as part of a Skilled Worker visa application under the UK's points-based immigration system. The Certificate of Sponsorship (CoS) number should be referenced in the appointment letter where the employer is a licensed sponsor.

Public sector employers in England, particularly NHS trusts, local authorities, and maintained schools, must issue appointment letters that comply with the relevant National Terms and Conditions of Service (such as the NHS Terms and Conditions of Service Handbook or National Joint Council conditions for local government workers) and that reference the applicable pay scales.

A UK Appointment Letter that satisfies the Employment Rights Act 1996 principal written statement requirements must contain the following key provisions.

Parties and start date must be stated precisely. The employer's full legal name and address, the employee's full name, the job title (or a brief description of the work), and the date employment is to begin are all mandatory under section 1 of the ERA 1996. The date on which the employee's period of continuous employment began should also be stated — this is important because statutory rights (unfair dismissal protection, statutory redundancy pay) depend on length of continuous service under section 212 of the ERA 1996.

Pay and benefits provisions must state the rate of pay, the pay interval (weekly, monthly), and the method of payment. The rate must meet or exceed the National Minimum Wage or National Living Wage under the National Minimum Wage Act 1998. Any contractual benefits — company car, private health insurance, life assurance, pension contributions above the statutory minimum — should be described or cross-referenced to a benefits schedule.

Working hours must be specified. The letter should state the normal hours of work (daily and weekly), and if applicable the days on which work is to be performed. Where hours may vary, the basis of variation should be explained. The employer must comply with the 48-hour maximum average working week under the Working Time Regulations 1998 (SI 1998/1833) unless the employee has opted out in writing.

Holiday entitlement must include the total annual leave entitlement (statutory minimum 5.6 weeks under the Working Time Regulations 1998, pro-rated for part-time workers) and the employer's policy on taking leave and pay in lieu of unused leave on termination.

Probationary period provisions should specify the length of any probation (typically three to six months), the shorter notice period during probation, the process for conducting probationary reviews, and the basis on which the employer may extend or terminate employment during probation.

Notice period requirements are mandatory particulars under section 1 of the ERA 1996. The minimum statutory notice is one week after one month of continuous employment, rising by one week per complete year up to a maximum of 12 weeks under section 86 of the ERA 1996. Many employers contractually agree longer notice periods.

Conditions of offer should be stated clearly if the offer is conditional. Common conditions include satisfactory references, a satisfactory DBS (Disclosure and Barring Service) check, evidence of right to work in the UK under section 15 of the Immigration, Asylum and Nationality Act 2006, and professional qualification verification.

Additional compliance elements for a Appointment Letter (UK) used in United Kingdom include: 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.
