Two colleagues meet beside an onboarding checklist and ID card.

In this guide

Before your first employee starts

  • Confirm the relationship, employing entity and full commitment.
  • Recruit fairly and put the agreed terms in writing.
  • Finish the right checks before work begins.
  • Prepare payroll, pensions, insurance and safety early.
  • Keep one private record of what was agreed and completed.

Confirm the relationship and full employment cost

Write down the real working arrangement: duties, control, substitution, location and equipment. Those facts help distinguish an employee, worker and genuinely self-employed supplier.

The label alone does not settle status. Use the current employment-status checklist and record the facts behind the conclusion. Review it if the arrangement changes in practice.

Confirm which legal entity will employ the person. Then cost the commitment, including salary, employer National Insurance, pension contributions, paid leave, equipment, software and any role-specific insurance or training. A first hire is usually a recurring commitment, not a salary plus a laptop.

Once the offer is accepted, use the onboarding checklist to assign the practical work and track what is ready.

Recruit fairly and make a clear offer

Turn the role into a short set of criteria tied to the work. Use the same core criteria for comparable candidates, make it easy to request reasonable adjustments and keep a brief record of the decision. Avoid collecting information because it might be useful later.

Acas sets out the Great Britain hiring sequence, from advertising through offers and induction. Northern Ireland uses a separate equality framework, covered by the Equality Commission's recruitment guidance.

The offer should name the employer, role, pay, normal hours, workplace, start date and any genuine conditions. Do not hide a material condition in a later policy. If a check is not required or relevant to the role, leave it out rather than building a larger candidate file.

Finish the terms and checks before day one

An employment contract is the agreement between the parties. The written statement records particulars the employer must provide. They overlap, but they are not necessarily the same document.

In Great Britain, the principal written statement is due on or before the first day, with specified wider information due within two months. Northern Ireland has a different entitlement and timetable. Use the Great Britain particulars list or the Northern Ireland guidance, then keep the accepted version.

Complete the appropriate right-to-work route before employment begins. Follow the Home Office employer guide and keep the dated result, not merely the document or share code used to start the check. Add a criminal-record or regulated-role check only where the role and current eligibility rules support it.

Set up insurance, safety, payroll and pensions

Arrange Employers' Liability cover through the route that applies to the business and make the certificate available as required. Great Britain uses the GOV.UK insurance guidance; Northern Ireland has a separate HSENI route.

Identify the actual risks in the workplace or homeworking arrangement and put sensible controls in place. Every employer needs safety arrangements. In both Great Britain and Northern Ireland, employers with five or more employees must write down their health-and-safety policy. Use the HSE small-business guidance in Great Britain or the HSENI policy route in Northern Ireland.

Register and prepare PAYE early enough for the first payday. Collect the current starter information, pass it to payroll and agree who will check the first submission. GOV.UK explains the P45 and starter route.

Pension duties begin when the first employee starts even if that person does not need to be enrolled immediately. Give the pension assessment, communications and declaration work a named owner and use the current regulator guidance.

Create the minimum dependable people record

Keep the information needed to run the employment relationship and meet a defined duty. For each field or document, know why it exists, who needs access, how it stays current and what will trigger review or deletion.

Separate identity, bank, health and right-to-work evidence from ordinary role details. A manager may need a working pattern and emergency route without receiving payroll or medical records. Give the person clear privacy information and a practical way to correct their details.

The ICO employment-record guidance is a useful test for purpose, access, accuracy and retention. Keep earlier versions of terms and policies when they are replaced so the record still explains what applied at the time.

Set the working pattern, leave year, bank-holiday treatment and absence-reporting route before they are needed. Make the current disciplinary and grievance procedures easy to find without asking a new employee to absorb a handbook on their first morning.
