What do you legally have to do before hiring your first employee?
A specific and fairly short list — and the risk is not that it is complicated, but that several items are easy to miss entirely until something goes wrong.
Before they start:
Check the right to work. A statutory check of original documents or a share code, done before employment begins, with a dated copy retained. Doing this correctly provides a statutory excuse against a civil penalty; doing it late does not.
Register as an employer with the tax authority and set up payroll before the first payday.
Get employers' liability insurance. This is compulsory from the day you employ someone, with daily penalties for not holding it, and it is the item most frequently overlooked.
Decide the terms, since a written statement of the main terms must be given on or before the first day — not within two months, which is the outdated position many templates still reflect.
Check any role-specific requirements — criminal record checks where the role qualifies, and professional registration.
Once employed, you are responsible for:
Paying at least the minimum wage for the worker's age band, and getting the arithmetic right where deductions, uniforms or unpaid training are involved — underpayment through these routes is a common enforcement finding.
Operating PAYE, deducting tax and National Insurance and paying employer contributions.
Pension auto-enrolment, assessing eligibility from the first pay period and enrolling those who qualify. There are duties even if nobody is eligible.
Statutory leave and pay — holiday, sick pay, and family leave entitlements.
Health and safety duties, including a risk assessment.
Data protection, since employee records are personal data.
Rights that exist from day one: protection from unlawful discrimination, the right to the written statement, statutory minimum notice and paid holiday accrual. Some rights require qualifying service, and that threshold has been subject to reform.
Contractors are not a way around this. Employment status is determined by the reality of the arrangement, not the label on the contract.
General information, not legal advice.
