Hiring Your First Employee

BusinessLast reviewed: 1 April 20257 min

Taking on your first employee is a significant milestone and creates a range of legal and administrative obligations. Missing any of the key steps can result in fines, employment disputes, or worse. This guide covers every step you need to take before your new employee starts work.

Important

Failing to register as an employer and operate PAYE is a criminal offence. HMRC can charge penalties on unpaid PAYE and NI contributions plus interest.

Key points

  • You must register as an employer with HMRC at least four weeks before the first payday.
  • You must carry out a right to work check and retain the documentation before the employee starts work.
  • A written statement of particulars (employment contract) must be given on or before the first day of work.
  • You must automatically enrol eligible employees into a workplace pension scheme.
  • Employers' liability insurance must be in place from the first day of employment.
  • You must pay at least the National Minimum Wage or National Living Wage for the employee's age.

Before the Employee Starts

There are several legal steps you must complete before your new employee begins work:

  • Right to work check: You must check that the individual has the legal right to work in the UK and retain a copy of the evidence (see our right to work guide). This must be done before they start — a post-start check does not provide a statutory excuse if it later emerges the person did not have the right to work.
  • Register as an employer with HMRC: Register for PAYE at least four weeks before the first payday. HMRC will issue you with a PAYE reference number and employer login. Use PAYE software (or a payroll provider) to run payroll and submit RTI data to HMRC.
  • Employers' liability insurance: Obtain a policy with at least £5 million of cover before day one. Display the certificate at your workplace.
  • Written statement of particulars: Prepare an employment contract or written statement of particulars. Since April 2020, this must be provided on or before the employee's first day.

The Employment Contract

The written statement of particulars is legally required from day one. It must include:

  • Employer's and employee's name
  • Start date and any previous service that counts towards continuous employment
  • Job title or job description
  • Place of work
  • Remuneration — pay rate, frequency of payment
  • Working hours
  • Holiday entitlement (and holiday pay)
  • Sick pay arrangements
  • Notice periods (both employer and employee)
  • Pension details (or a note that a workplace pension will be auto-enrolled)
  • Whether a collective agreement applies
  • Details of any probationary period

Additional terms — such as confidentiality clauses, post-termination restrictions, or details of other benefits — should also be included if relevant. Keep a signed copy of the contract in the employee's personnel file.

Auto-Enrolment: Workplace Pensions

Every employer must automatically enrol eligible employees into a qualifying workplace pension scheme. Auto-enrolment obligations apply from your first employee's start date — there is no grace period for new employers.

You must automatically enrol an employee if they:

  • Are aged 22 or over and under state pension age
  • Earn more than £10,000 per year (£192 per week, £833 per month)
  • Work in the UK

The minimum total pension contribution is currently 8% of qualifying earnings, of which you must contribute at least 3%. The employee contributes at least 5% (including tax relief). You must:

  • Choose a qualifying pension scheme (such as NEST, which is free for employers)
  • Enrol eligible employees within six weeks of their start date
  • Write to new employees within six weeks, explaining their auto-enrolment
  • Declare your compliance with The Pensions Regulator within five months of your first duties date

Ongoing Employer Obligations

Once you have made the initial steps, there are ongoing obligations to maintain:

  • Payroll: Run payroll on each payday, submit RTI data to HMRC, and pay over PAYE and NI contributions by the 22nd of each month (if paying electronically)
  • Payslips: Provide a written payslip on or before each payday, itemising all deductions
  • Employment records: Maintain personnel files, payroll records, and right to work documentation
  • Health and safety: Once you have employees, additional health and safety obligations apply — see our health and safety guide
  • Minimum wage: Ensure pay rates are reviewed each April when NMW rates increase
  • Holiday: Manage and track annual leave entitlement
  • Re-enrolment: Every three years you must re-enrol any employees who previously opted out of the pension scheme

Frequently asked questions

Can I pay my new employee cash in hand?
Paying cash in hand and not running it through PAYE is illegal if the employee earns above the PAYE threshold. You must operate PAYE, deduct income tax and National Insurance, and submit RTI data to HMRC — regardless of how the payment is physically made (cash, bank transfer, or otherwise). Cash in hand payments that are not declared constitute tax evasion and can result in significant penalties for the employer.
My new employee has a student loan. What do I need to do?
Your employee should notify you of any student loan on the starter checklist (or it will appear in information from HMRC). Your payroll software will apply the appropriate student loan deduction plan (Plan 1, Plan 2, Plan 4, or Postgraduate Loan) based on the information provided. Student loan repayments are deducted through PAYE alongside income tax and NI. HMRC will tell you if you need to start or stop making deductions.
Do I need to provide a contract to a part-time or zero-hours worker?
Yes. All employees — including part-time and zero-hours workers — are entitled to a written statement of particulars from day one. For zero-hours workers, the contract should clearly state that there are no guaranteed hours, but that when hours are offered and accepted, the minimum wage and other statutory rights apply. Zero-hours workers have the same rights to holiday pay, pension auto-enrolment, and statutory sick pay as other workers once they meet the eligibility criteria.
How do I choose a workplace pension scheme?
The most common option for small employers with few employees is NEST (National Employment Savings Trust), a government-backed scheme with no employer charges. Other options include The People's Pension, NOW: Pensions, and various insurance company schemes. Your payroll software provider may also have a preferred pension partner. Compare on charges, investment options, and ease of administration. The Pensions Regulator's website has guidance on choosing a scheme.
What is the cost of hiring your first employee?
Beyond the employee's salary, you must budget for employer National Insurance contributions (13.8% of earnings above the secondary threshold of £9,100 for 2025/26), employer pension contributions (minimum 3% of qualifying earnings under auto-enrolment), and employers' liability insurance (compulsory by law, from around £100–£500 per year for a small business). There are also one-off costs such as advertising, Disclosure and Barring Service (DBS) checks if required, and any training.
Do you need to provide a pension from day one of employment?
Auto-enrolment applies from the worker's first day if they are aged between 22 and State Pension age and earning over £10,000 per year. Eligible workers must be automatically enrolled into a qualifying pension scheme within six weeks of starting work — there is no waiting period. You must write to each new employee within six weeks of their start date explaining their pension rights. Workers earning below £10,000 can opt in but do not have to be auto-enrolled.
