A job offer, payroll form and handbook do not automatically add up to a compliant written statement. Employers must give employees and workers their main conditions when they start. Some information is due on day one, other information can follow within two months, and calling a document an employment contract does not fix missing terms.
The written statement and the employment contract are not the same thing
The written statement of employment particulars is the document or group of documents setting out the main terms of the working relationship. GOV.UK makes clear that it is not, by itself, the employment contract. A contract can also include agreed verbal terms, terms implied by conduct, incorporated policies and duties imposed by law.
A clear principal statement provides the starting record of what was agreed. If the offer letter, statement, handbook and manager's promises conflict, the business has created an avoidable dispute about pay, hours, location, duties or benefits.
Employees and workers are covered from the start
Employers must provide a written statement to employees and workers. The principal statement is due on the first day of employment, not after a probation period and not only when somebody asks for it.
Do not rely on the label at the top of the document. Describing somebody as self-employed does not make that their legal status if the practical relationship points to worker or employee status. Consider personal service, control, mutual obligations, substitution, financial risk and how the arrangement works in reality. Seek specific advice where status is uncertain.
What the principal statement should contain on day one
The principal statement must identify the parties, job title or work description and start date. For an employee, it should also record any earlier date that counts towards continuous employment. It must explain pay and pay frequency; normal hours and days; how hours or days may vary; holiday entitlement; and the normal place or places of work.
It must also cover the expected duration and end date of a fixed-term role where relevant, the length and conditions of probation, benefits, and obligatory training including whether the employer pays for it. If the person will work outside the UK for more than one month, additional information is required about the period abroad, currency, additional pay or benefits and return arrangements.
Information about sick pay and procedures, other paid leave and notice periods must also be available on day one. It can sit in the principal statement or in another reasonably accessible document. If a handbook or intranet policy is used, name it clearly and ensure the employee or worker can actually access the current version.
Variable hours need more than the words 'as required'
Small employers often create uncertainty around variable hours, overtime and shift changes. State the normal days and hours, when and how they can vary, whether Sunday or night work may be required, and the basis on which overtime is offered or required. Explain any guaranteed hours separately from additional hours that are genuinely optional.
The wording must reflect operational reality. A contract promising fixed Monday-to-Friday hours while managers routinely impose weekend work will not become accurate through custom alone. Review the rota model, overtime practice and pay rules together before issuing the document.
Check pay, hours and probation before the employee starts.

Discuss an employment-document reviewWhat can be provided within two months
The wider written statement can follow within two months of the start date. It should cover pensions and pension schemes, collective agreements, rights to non-compulsory training, and disciplinary and grievance procedures. Some of this information can be supplied by referring to an accessible policy rather than reproducing every rule in the principal statement.
References need to be precise. 'See company policy' is unhelpful if several versions exist, the employee has no access or the policy says something different. Identify where the document is held, who can provide it and whether the relevant term is intended to be contractual or non-contractual.
Probation clauses must explain the process, not just the length
The statement should specify how long probation lasts and its conditions. A workable clause should be supported by a review process: standards, review dates, who decides the outcome, whether the period can be extended and what notice applies. Managers then need to hold the reviews and record the decision rather than allowing probation to expire unnoticed.
Probation is a contractual management arrangement; it does not switch statutory protections off. Discrimination rights and several automatically unfair dismissal protections can apply from the beginning. Changes to the ordinary unfair-dismissal qualifying period from 1 January 2027 also make early, documented performance management increasingly important.
Update the statement when terms change
Employers must tell an employee or worker about changes to their written particulars within one month of the change. First establish whether the business is entitled to make the change. A written notification records an agreed or otherwise lawful change; it does not create consent to reduce pay, relocate work or change hours where consent or a proper contractual process is required.
Keep the offer, signed statement, agreed amendments and applicable policy versions together. If terms are updated across the workforce, check consistency with payroll, rotas, benefits, job adverts and what managers are telling staff.
Day-one written statement checklist
For a growing North East SME, one reliable onboarding pack is usually easier to manage than different offer letters and old templates held by individual managers. The pack should still be adapted for the person's status, hours, workplace, benefits and role rather than issued unchanged to everybody.
- Confirm whether the individual is an employee, worker or genuinely self-employed.
- Issue the principal statement no later than the first working day.
- Check names, role, start date and any recognised continuous service.
- State pay, pay interval, hours, days and how they may vary.
- Explain holiday, place of work, duration and fixed-term end date where applicable.
- Record probation length and conditions, benefits and mandatory training.
- Make day-one sick pay, paid-leave and notice information accessible.
- Provide pensions, collective agreements, non-compulsory training and procedure information within two months.
- Check every cross-reference against the current handbook or policy.
- Record agreed changes and issue updated particulars within one month.
Give employees and workers a complete principal statement on day one, provide the wider information within two months and keep the record aligned with the real working arrangement. Clear terms support good onboarding and remove disputes that vague or conflicting documents create.
