Employment Offer Letter (UK)

An Employment Offer Letter in the United Kingdom confirms the role, terms, or facts being offered or attested to and gives the recipient a written record they can rely on, with its requirements set by the Employment Rights Act 1996.

In England and Wales, an employment relationship can technically be formed as soon as a verbal offer is accepted. This means that the moment a candidate says 'yes, I accept the offer', a legally binding contract of employment may exist, even if nothing has been written down. The terms of that contract will be implied from the parties' course of dealing, any written correspondence, and statutory defaults under the Employment Rights Act 1996. This is why getting the offer letter right is so important: the terms you set out in the offer letter may well become the terms of the employment contract if the candidate accepts.

A well-drafted employment offer letter serves several critical purposes. First, it confirms to the candidate that they have been selected and creates a clear record of what was offered and when. This is important for both parties: the employer needs a paper trail showing that the offer was conditional on satisfactory references or a right to work check, while the candidate needs certainty about what they have accepted so they can hand in their notice to their current employer with confidence.

Second, the offer letter manages expectations about when the full employment contract will follow. Under section 1 of the Employment Rights Act 1996, the written statement of employment particulars must be provided on or before the employee's first day. The offer letter is not a substitute for this written statement, but it should make clear that a full contract will be issued before the start date.

Third, a conditional offer letter protects the employer from being bound by an employment contract before essential pre-employment checks have been completed. The most important of these in the UK is the right to work check under section 15 of the Immigration, Asylum and Nationality Act 2006. Employers who fail to carry out the prescribed checks before an employee starts work may be liable for a civil penalty of up to £60,000 per illegal worker, and in some cases criminal prosecution. Making the offer conditional on a satisfactory right to work check means that the offer can be withdrawn without legal consequence if the check cannot be completed satisfactorily.

Other common conditions include satisfactory references from previous employers, satisfactory completion of a Disclosure and Barring Service (DBS) check (formerly CRB check) where the role involves working with children or vulnerable adults, medical clearance where the role has particular physical requirements, and proof of professional qualifications where a regulated professional qualification is required for the role.

The offer letter should also address the probationary period. Most UK employers impose a probationary period of three to six months, during which both parties can assess the suitability of the employment relationship. During the probationary period, the notice period is typically shorter — often one week — and performance management procedures may be more efficient. Setting out the probationary period clearly in the offer letter avoids any later dispute about whether such a period was agreed.

Finally, the offer letter creates the first formal record of the employer-employee relationship for payroll and HR purposes. HMRC requires employers to operate PAYE from the employee's first day of work, and having a clear written record of the agreed salary and start date is essential for setting up payroll correctly.

You need an employment offer letter every time you hire a new employee in the UK, without exception. Whether you are hiring a part-time retail assistant on the National Minimum Wage or a full-time Finance Director on a six-figure salary, the process should always include a formal written offer letter before the employee starts work.

The most common situation is a straightforward permanent hire following a competitive recruitment process. You have interviewed several candidates, selected your preferred candidate, made a verbal offer which they have provisionally accepted, and now need to formalise the offer in writing. The offer letter confirms the key terms, sets out any conditions, and asks the candidate to countersign and return a copy to confirm their acceptance.

Fixed-term contracts also require a formal offer letter. This should set out not only the start date but also the end date or the event that will bring the contract to an end, and ideally the reason for the fixed term. Employees on fixed-term contracts of four or more years have the right under the Fixed-Term Employees (Prevention of Less Favourable Treatment) Regulations 2002 to request conversion to a permanent contract, so being clear about the reason for the fixed term is important.

Where an internal candidate is being promoted or transferred to a different role, a new offer letter should be issued confirming the new role, salary, and any other changes to their terms and conditions. A verbal agreement or a manager's email is not sufficient — any material change to the terms of an employment contract requires the employee's written consent.

Rehires — where a former employee is being taken back on — also need a fresh offer letter. Depending on the length of the break in service, the employee may or may not retain their previous continuity of employment under the Employment Rights Act 1996. The offer letter should address this point explicitly to avoid any later dispute about qualifying periods for unfair dismissal, redundancy pay, or other statutory rights that depend on continuity.

Remote and hybrid roles require particular care. Where an employee will be working from home either full-time or on a hybrid basis, the offer letter should specify the primary place of work and, if relevant, the employer's right to require the employee to attend the office. This is particularly important in light of the Employment Relations (Flexible Working) Act 2023, which strengthened employees' rights to request flexible working from day one of employment.

A UK employment offer letter should contain several essential elements. The opening should identify the employer clearly — including the company's full legal name, registered address, and Companies House registration number if applicable — and address the letter personally to the candidate by their full name.

The job title and department should be stated precisely. Vague job titles cause problems later, particularly if there is a dispute about whether an employee was required to carry out certain duties. The letter should also state the reporting line — who the employee will report to — and the primary place of work, including the address of the office or site where the employee will be based.

The salary or rate of pay must be stated clearly, including the pay frequency (weekly, monthly, or four-weekly), the method of payment (BACS bank transfer), and the date on which pay will normally be made. All UK employees must be paid at least the National Living Wage (£12.71 per hour from April 2026 for those aged 21 and over) or the relevant National Minimum Wage rate. If the role is salaried, the annual gross salary should be stated, together with the equivalent hourly rate if relevant.

The proposed start date is essential. This is the date from which continuous employment begins for the purposes of the Employment Rights Act 1996, and it triggers the employer's obligation to provide the written statement of employment particulars on or before that date. The letter should also confirm the normal working hours and days, and whether the employee is required to work additional hours.

Any conditions attached to the offer must be stated clearly. The most important are the right to work check, satisfactory references, and any DBS check. The letter should make clear that if a condition is not satisfied, the offer may be withdrawn.

The probationary period should be addressed, including its duration, the notice period during the probationary period (typically one week), and what happens at the end of the probationary period if performance is satisfactory.

Holiday entitlement is often mentioned in the offer letter, at least in outline. The statutory minimum is 28 days per year for a full-time employee (inclusive of bank holidays unless your policy provides for bank holidays to be additional). Stating the contractual entitlement in the offer letter avoids any later confusion.

The letter should close by asking the candidate to sign and return a copy to confirm their acceptance, and should ideally give a deadline for acceptance — typically five to ten working days — to allow the employer to move on to the next candidate if the offer is not accepted within a reasonable time.

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.
