Hiring your first employee is a significant milestone for any UK small business. It brings new opportunities but also legal and administrative responsibilities that must be carefully managed to ensure compliance and a positive working relationship. Understanding your obligations under UK employment law is essential to avoid pitfalls and build a successful team.

Payroll & PAYE You need to operate PAYE to deduct Income Tax and National Insurance contributions.

Registering as an Employer with HMRC

Before employing anyone, you must register as an employer with HM Revenue & Customs (HMRC). This registration informs HMRC that you will be operating PAYE (Pay As You Earn) to handle tax and National Insurance deductions for your employee. It usually takes around 5 working days to receive your employer PAYE reference number, so plan ahead.

Registration is free and can be completed online through the GOV.UK website. Once registered, you must submit payroll information to HMRC on or before each payday using real-time information (RTI) submissions.

Failure to register promptly can lead to penalties and fines. If you take on casual or part-time workers later, you will not need to re-register but must notify HMRC of all new employees.

Checking Right to Work in the UK

It is a legal requirement under the Immigration, Asylum and Nationality Act 2006 to check that all employees have the right to work in the UK. This helps prevent illegal working and protects your business from penalties.

You must carry out these checks before the employee starts work, or as soon as possible afterwards if the employee has a time-limited right to work. Acceptable documents for verification include a UK passport, biometric residence permit, or a combination of documents such as a birth certificate and National Insurance card.

How to Conduct Right to Work Checks

  • Ask the employee to provide original documents that prove their right to work.
  • Check the documents carefully, ensuring they are valid and belong to the employee.
  • Take and securely keep copies of the documents as evidence of the check.
  • If the employee has a time-limited right to work, set reminders to re-check before expiry.

For detailed guidance, refer to the official GOV.UK right to work checks page and use the online Home Office checking service if applicable.

Employment Contract and Written Statement of Employment Particulars

Under the Employment Rights Act 1996, every employee must receive a written statement of employment particulars within two months of starting work. This document outlines the main terms and conditions of their employment, helping to prevent disputes later.

The written statement must include details such as job title, pay, hours of work, holiday entitlement, notice periods, and disciplinary and grievance procedures. While not all terms need to be in a formal contract, the statement serves as evidence of the agreed terms.

Providing a clear, comprehensive contract fosters trust and clarity between you and your new employee. Consider including policies on confidentiality, data protection (in line with UK GDPR), and health and safety responsibilities.

Payroll, PAYE, and Tax Obligations

Once registered as an employer, you must operate PAYE to deduct Income Tax and National Insurance contributions from your employee’s wages. This includes:

  1. Calculating gross pay, tax, and NICs based on HMRC’s tax codes and thresholds.
  2. Paying your employer National Insurance contributions.
  3. Submitting RTI reports to HMRC each payday.
  4. Providing employees with payslips showing earnings and deductions.
  5. Reporting benefits and expenses if applicable.

You can either manage payroll yourself using HMRC-approved software or outsource it to a payroll provider or accountant. Ensure you stay up to date with changes in tax rates and employment law.

Onboarding and HR Compliance

Effective onboarding is crucial for integrating your new employee and ensuring compliance with UK employment law. This process should cover:

  • Health and safety training in line with the Health and Safety at Work Act 1974.
  • Data protection briefing to comply with UK GDPR, explaining how employee data will be used and stored.
  • Introducing workplace policies such as equal opportunities, anti-harassment, and grievance procedures, reflecting the Equality Act 2010.
  • Setting clear expectations and objectives for the role.

Keep detailed records of all training and signed policy acknowledgements to protect your business and support employee wellbeing.

Ongoing Employer Responsibilities

Hiring your first employee is just the beginning. You must maintain compliance with employment law throughout the employment relationship. This includes:

  • Providing statutory rights such as holiday entitlement, sick pay, and maternity/paternity leave.
  • Keeping accurate payroll and employment records.
  • Ensuring workplace health and safety standards are met.
  • Conducting regular performance reviews and providing feedback.
  • Handling disciplinary or grievance issues fairly and in line with ACAS Code of Practice.

Regularly review your HR policies and stay informed about changes in legislation to mitigate risks and foster a positive workplace culture.

Quick Summary:
  • Register as an employer with HMRC before paying your first employee.
  • Check every employee’s right to work in the UK before they start.
  • Provide a written statement of employment particulars within two months.
  • Operate PAYE to manage tax and National Insurance deductions.
  • Onboard employees with health, safety, and data protection training.
  • Maintain compliance with employment law and workplace policies throughout employment.

For complex hiring scenarios or legal questions, seek professional legal advice tailored to your business.

Do I need a formal contract for my first employee?

While a formal written contract is not strictly required, you must provide a written statement of employment particulars within two months of the employee starting, which outlines the main terms and conditions. A clear contract helps avoid misunderstandings and is highly recommended.

What records must I keep as an employer?

You must keep payroll records, tax and National Insurance details, working hours, holiday entitlement, and records of any disciplinary or grievance matters. These help demonstrate compliance with employment laws and support good HR management.

Can I hire someone before registering as an employer?

You can hire before registering, but you must register with HMRC before the first payday. Registering promptly avoids penalties and ensures you can operate PAYE correctly from the start.
