What is a written statement of particulars (Section 1)?

What it is, in one line

A written statement of particulars is the document that section 1 of the Employment Rights Act 1996 requires every UK employer to give every worker, setting out the principal terms of the employment relationship. It is often called a Section 1 statement.

It is not the employment contract itself — though most employers combine the two into a single document. It is the legal disclosure that crystallises what was agreed.

When it must be provided

Since 6 April 2020, the statement must be issued on or before the worker's first day of employment. Before that date the deadline was two months — the bring-forward to day one was a substantial tightening.

The same change widened the scope from "employees" to all "workers" — extending it to casuals, zero-hours staff, and most agency arrangements.

Who is entitled to one

• All employees
• All workers (under the wider Employment Rights Act test) including casuals and zero-hours
• Apprentices
• Agency staff (from the agency, as their employer)
• Fixed-term and short-term hires

The only meaningful exclusion is genuinely self-employed contractors, who are not workers.

What must be in the day-one statement

The Act splits required information into "day-one" items that must be in the principal statement, and supplementary items that can follow within two months. The day-one list:

• Names of employer and worker
• The start date
• The date continuous employment began (for workers transferring from another linked employer)
• Pay — amount, frequency, method of payment
• Hours of work, including any variable hours arrangements
• Holiday entitlement (including bank holiday treatment) and how it's calculated
• Place of work, or a statement that the worker can be required to work at different locations
• Job title or a brief description of the work
• Length of contract (if fixed-term, with the end date)
• Notice periods — what each side must give
• Probation period terms — length and any different rules during it
• Other paid leave (sickness, family leave) — entitlements and how to claim
• Any training the employer requires the worker to complete
• Any benefits not covered elsewhere (e.g. private medical, gym membership)

What can come within two months

These items can be in the principal statement or in a supplementary document delivered within two months:

• Pension scheme details (or a reference to a separate pension document)
• Collective agreements that affect the terms
• Any longer-term training entitlements not already specified
• Disciplinary and grievance procedures (or a reference to where they are)

Most modern employers include everything on day one, in a single document, simply because it's cleaner.

Statement vs contract — and why most do both

The Section 1 statement is a legal disclosure, not a binding agreement. The employment contract is the wider mutual agreement, which typically also includes:

• Restrictive covenants (non-compete, non-solicit, non-deal)
• Confidentiality and IP assignment
• Bonus and commission rules
• Code of conduct expectations
• Garden leave rights
• Payment in lieu of notice (PILON) clauses
• Variation clauses

A "contract of employment" issued on day one almost always satisfies both requirements at once. The Section 1 statement is then implicit — embedded inside the contract.

The risk of issuing only a Section 1 statement (without the wider contract) is that you have no enforceable position on confidentiality, IP, or restrictive covenants. The risk of issuing only a contract is that you may miss specific Section 1 disclosures and become liable for the missing-statement penalty.

What happens if you don't issue one

The penalty mechanism is unusual. There is no standalone right to claim — the worker can't go to tribunal just for not having a statement. But if the worker brings any other tribunal claim (unfair dismissal, unpaid wages, discrimination, etc.) and wins, the tribunal can additionally award:

• 2 weeks' pay (minimum) if the statement was missing or incomplete
• 4 weeks' pay (maximum) if the failure is "just and equitable"

Subject to the statutory cap on a week's pay (currently around £700, reviewed annually).

Far more important than the cash, missing statements signal systemic compliance failure. It's usually one of the first things a tribunal will note, and it influences how every other aspect of the employer's case is read.

Variations during employment

If a Section 1 term changes during employment — pay rise, new role, new working hours, different notice period — the employer must give the worker a written statement of the change within one month of it taking effect.

Section 1 changes that don't take effect immediately (a planned restructure, a future move) only need a statement when the change is operative.

Mass changes (e.g. pay scale uplifts) can be covered by a single notice referencing where the new figures are published, provided each affected worker is identifiable.

Common content failures

Vague hours of work

"Hours as required" is increasingly seen as a non-compliant statement. Even for variable hours, the document should specify the contractual minimum, the expected pattern, and how variations are determined.

Holiday calculation incomplete

A statement saying "5.6 weeks" is not enough. The Section 1 list specifically requires "any terms relating to entitlement to holidays, including public holidays, and holiday pay, sufficient to enable accurate calculation." That means: how it accrues, how part-year calculations work, how bank holidays are treated.

Place of work too narrow or too broad

Too narrow ("4 Acacia Avenue") creates problems on a small office move. Too broad ("anywhere in the UK") may be unenforceable. The standard is to name the primary location with a reasonable mobility clause.

Probation buried

Probation periods are now a day-one disclosure. The statement should specify length, performance review process, notice during probation, and any benefits delayed until passing probation.

Putting it into practice

A robust Section 1 process should:

1. Generate the statement automatically from the offer letter and contract template
2. Cover every day-one item in the principal document
3. Be issued before, not after, the start date — ideally with the offer
4. Capture the worker's signed acknowledgement
5. Track variations during employment, issuing supplementary statements within one month
6. Retain the statement and any variations for the duration of employment plus six years

The Section 1 statement is one of the cheapest pieces of compliance to get right and one of the most expensive to get wrong. Templates are widely available — what matters is that every worker has one, on day one, accurately reflecting their actual terms.
