Most new hire paperwork problems don't happen because employers forget. They happen because the hire started before the admin was finished. This checklist covers everything UK employers are legally required to collect, plus the documents most small businesses miss, so your next hire is fully sorted before they clock in for the first time.
What new hire paperwork is legally required in the UK
Three documents sit at the legally required core. Miss any of them and you're either breaking employment law or exposing yourself to a significant financial penalty.
Right to work documentation
Before anyone starts work, you must verify their right to work in the UK. This is not optional and it cannot be done retrospectively. The check must happen before employment begins.
Acceptable evidence includes a UK or Irish passport, a biometric residence permit, or an online share code check via the GOV.UK employer portal. You must keep a copy of the documents (or a record of the online check) for the full duration of employment and for two years after the person leaves.
Following updated Home Office guidance in February 2024, fines for employing someone without a valid right to work check now reach up to £45,000 per worker for a first breach, and £60,000 for repeat offences. That figure has tripled in the last few years. For a hospitality or retail business hiring regularly, this is not a theoretical risk.
Written statement of employment (your contract)
Since April 2020, UK employers must provide a written statement of employment particulars on or before the employee's first day. This is a legal requirement under the Employment Rights Act 1996 and it applies to all workers; full-time, part-time, casual, and zero-hours.
The document must cover:
- Job title and description
- Pay and pay frequency
- Working hours (including agreed contracted hours)
- Holiday entitlement
- Notice period
- Place of work.
Using an employment contract template is the most practical way to produce this quickly and consistently for every hire.
One common misconception: many small business owners still believe they have two months to issue a contract. That rule changed in 2020. Day one is now the deadline.
P45 or Starter Checklist
Ask every new hire for their P45 from their previous employer. This tells your payroll provider what tax code to apply from the start and helps avoid common payroll management mistakes.
If they don't have a P45 (common with first jobs, career gaps, or people coming from self-employment) they need to complete HMRC's Starter Checklist (sometimes still called a P46). Without one or the other, your payroll system will default to an emergency tax code, which typically means the employee is overtaxed on their first payslip and has to claim it back, increasing the risk of payroll errors and compliance issues. It's a minor issue operationally; to the employee, it's an annoying start.
New employee paperwork most small businesses miss
Beyond the legal minimum, there's a second layer of documents that protect you operationally. These aren't always legally mandated, but their absence creates real problems, usually at the worst possible moment.
| Document | Why it matters |
|---|---|
| Bank details | Without these, you can't run payroll. Chasing bank details after a hire starts is common and entirely avoidable. |
| Emergency contact details | Required for health and safety purposes; often collected verbally and never filed. |
| Signed employee handbook acknowledgement | If a policy dispute ever arises, signed acknowledgement is your paper trail. |
| Pension auto-enrolment confirmation | Legally required under the Pensions Act 2008 for eligible workers. The opt-out is the employee's right, not the default. |
| Benefits enrolment | Enrolment windows are often missed entirely when the hiring process is rushed. |
| DBS check (where required) | Mandatory for roles involving children, vulnerable adults, healthcare, or financial responsibility. Check eligibility via GOV.UK. |
The signed handbook is the one most operators skip. It takes 30 seconds to produce and sign, and it matters enormously if you ever need to demonstrate that an employee knew your policies.
New hire paperwork checklist: before the first shift
Use this as a pre-start sign-off for every hire. Organise it in three phases.
Before the offer is confirmed
- Right to work check completed and documented
- DBS check initiated (if role requires it)
- Employment contract template prepared and ready to send
Before the start date 4. Written statement of employment sent and signed 5. P45 received, or Starter Checklist completed and submitted to payroll 6. Bank details collected 7. Emergency contact details collected 8. Pension auto-enrolment communication sent 9. Employee handbook sent and acknowledgement received
On or before day one 10. New hire added to roster management and scheduling system and first shifts assigned 11. All documents filed in employee record 12. Payroll provider updated with new employee details
If item 10 is the first thing you're doing, items 1 through 9 should already be done.
What happens when paperwork isn't done before day one
Most compliance failures come down to timing. The hire was confirmed, the start date was agreed, and the admin got left for later. Here's what "later" can cost.
- No right to work check: You have no statutory excuse against a civil penalty. If an investigation finds you employed someone without checking, the fine starts at £45,000. This applies regardless of whether the employee was actually eligible; if you didn't check, you have no defence, and inaccurate timekeeping and attendance records won’t help you retroactively.
- No written statement by day one: Employees can take a claim to an Employment Tribunal if they're not provided a written statement of employment on time. A tribunal can award up to four weeks' pay as compensation, even if no other dispute exists. It's entirely avoidable.
- No P45 or Starter Checklist: The employee gets emergency-taxed on their first payslip. They'll notice. It creates an unnecessary admin correction cycle and a poor first impression of your payroll process.
None of these are edge cases. They happen regularly in shift-based businesses where hiring is fast, informal, and frequent.
