Every person you employ in the UK, whether full-time, part-time, or on a zero-hours contract, has a legal right to a written statement of their employment terms from their very first day. Get this wrong and a tribunal can add an automatic penalty on top of any other claim. This guide covers exactly what must be included and when.
Quick Answer
UK employers must give employees and workers a written statement of employment particulars on or before their first day of work. The principal statement must cover most mandatory terms, including pay, hours and holiday entitlement, immediately. Only three items, pension arrangements, collective agreements, and disciplinary or grievance procedures, can follow within two months of the start date.
Written Statement vs Employment Contract: What’s the Difference?
A contract of employment can technically exist without anything written down, since it forms the moment someone starts work, gets paid, and acts on the terms offered. The written statement of particulars is the specific legal document required under the Employment Rights Act 1996 setting out the key terms in writing. In practice, most employers combine the two into a single written contract that satisfies both, but understanding the distinction matters if a dispute ever reaches a tribunal.
Who Is Entitled to a Written Statement?
Both employees and workers are entitled, regardless of how many hours they work each week. This includes full-time, part-time, fixed-term, and zero-hours arrangements. There is no minimum length of service required, and dismissing someone for asserting this right is automatically unfair dismissal with no qualifying period.
What Must Be in the Principal Statement (Day One)
- The employer’s and employee’s names
- The start date, and the date continuous employment began if different
- Job title or a brief description of the work
- Pay, including the amount and how often it is paid
- Hours of work, including any variability
- Holiday entitlement, including how it is calculated
- Place of work, and details if the role involves working in different locations
- Notice periods on both sides
- How long the job is expected to last, if it is not permanent
- Any probationary period and its conditions
- Details of other benefits
- Whether there are other paid leave entitlements, such as maternity or paternity leave
Most of these mandatory particulars must be in the employee’s hands on or before their first day. This is a day-one right, not something that can wait until the role has settled in.
What Can Follow Within Two Months
Three items can legally be provided separately, within two months of the start date, rather than in the principal statement itself:
- Pension scheme and contribution details
- Any collective agreements affecting the employment
- Disciplinary and grievance procedures, or where to find them
Everything else needs to be in writing from day one. This distinction catches out a lot of new employers who assume the whole document has a two-month grace period.
What Happens If You Don’t Provide One?
If an employee brings a separate tribunal claim, such as unfair dismissal or a wage dispute, and the employer failed to provide a compliant written statement, the tribunal can add an automatic uplift of two to four weeks’ pay on top of any other award. This applies even if the written statement itself was never the substance of the original claim, so the cost of getting this wrong compounds whatever else goes wrong in the employment relationship.
Statutory Minimums the Contract Cannot Undercut
Whatever a contract says, certain statutory minimums apply automatically and cannot be contracted out of:
| Entitlement | Current Minimum |
|---|---|
| National Living Wage (age 21 and over) | £12.71 per hour from April 2026 |
| Paid annual leave | 5.6 weeks a year, pro-rated for part-time staff |
| Statutory Sick Pay | From day one, no lower earnings threshold |

Common Mistakes Employers Make
- Assuming an offer letter alone satisfies the written statement requirement, when key particulars are missing
- Treating the staff handbook as a substitute for the specific particulars the law requires in the contract itself
- Delaying the written statement until after the employee’s first day
- Using a template that has not been updated for current statutory minimums, such as an outdated minimum wage figure
- Having no signed or dated record of the terms actually issued, which weakens the employer’s position if a term is later disputed
Changing Contract Terms Later
Once agreed, contract terms cannot generally be changed unilaterally. Employers need the employee’s genuine agreement, or a clear contractual right to vary specific terms, before making a change. Forcing a change without agreement can amount to a breach of contract, and in serious cases the employee may treat it as constructive dismissal.
Frequently Asked Questions
When must a written statement of employment be given?
On or before the employee’s first day of work, for most mandatory particulars. Three items, pensions, collective agreements, and disciplinary or grievance procedures, can follow within two months.
Do part-time and zero-hours workers get a written statement?
Yes. The right applies to employees and workers regardless of hours worked, including zero-hours arrangements.
What happens if an employer doesn’t provide a written statement?
If the employee brings another successful tribunal claim, the tribunal can add an automatic award of two to four weeks’ pay for the missing or incomplete written statement.
Is a written statement the same as an employment contract?
Not technically, though in practice most employers combine both into a single document. The written statement is the specific legal minimum required by the Employment Rights Act 1996.
Can an employer change contract terms without agreement?
Generally no. Changing terms usually requires the employee’s genuine agreement or an existing contractual right to vary that specific term.
