How to hire your first employees in the UK, legally and well.

The first few employees set the culture, standards and pace of everything that follows. They are also a large, ongoing financial commitment, and in the UK hiring brings legal duties from day one. This guide covers deciding when to hire, running a sound process and the core compliance steps. It is general information, not legal advice; employment law is being reformed, so check GOV.UK and Acas for current rules.

Decide whether to hire

• Hire for the constraint. The role should remove the biggest bottleneck to revenue or the biggest risk.
• Know the full cost. Salary plus employer National Insurance, pension contributions, equipment, software, recruitment and management time. The hiring and team cost planner calculates this.
• Check runway. A rule of thumb: be confident you can fund the role for at least a year, or that it will pay for itself before cash gets tight.
• Consider alternatives: a contractor, an agency, an outsourced service, a part-time hire or a volunteer role for a defined project.

Run a good hiring process

1. Write a scorecard before the job advert: the role’s purpose, three to five outcomes expected in the first year and the skills needed to deliver them.
2. Advertise honestly, including salary range and any equity. Inclusive, plain language widens the pool.
3. Use a structured process: the same questions for every candidate, a practical task close to the real job, and scoring against the scorecard.
4. Take references and talk to people who have managed the candidate.
5. Make a written offer covering salary, start date, any conditions and equity terms.

UK essentials before day one

• Right to work checks. Check every new employee’s right to work in the UK before they start, and keep a record. See checking a job applicant’s right to work. Sponsoring workers from overseas needs a sponsor licence and has its own rules.
• Written statement of employment particulars. Employees are entitled to a written statement of their main terms from day one. Most companies issue a full employment contract. See employment contracts on GOV.UK.
• IP and confidentiality. Make sure the contract assigns IP created in the job to the company and protects confidential information.
• PAYE. Register as an employer with HMRC before the first payday and run payroll, reporting each payment on or before payday.
• Pension auto-enrolment. Assess each worker. At the time of writing, eligible jobholders are aged 22 to State Pension age and earn over £10,000 a year; minimum total contributions are 8 percent of qualifying earnings, with at least 3 percent from the employer. You must also complete a declaration of compliance with The Pensions Regulator.
• Employers’ liability insurance is a legal requirement for most employers.
• Minimum wage, holiday and sick pay. Pay at least the National Minimum Wage or National Living Wage, give statutory holiday (5.6 weeks a year for full-time staff, which can include bank holidays) and statutory sick pay where it applies.
• Data protection. Employee data is personal data under UK GDPR; tell staff how you use it.

Onboarding

Plan the first 30, 60 and 90 days: who they meet, what they learn, and what they will have delivered. Agree probation objectives in writing and review them on schedule.

Worked example

Pebblecode is a fictional Birmingham tech startup selling inventory software to craft breweries. At £22,000 MRR the two co-founders were split between selling and support. They wrote a scorecard for a customer success manager, with first-year outcomes of halving onboarding time and cutting early churn. They used the team cost planner to see the full annual cost, confirmed it fitted their forecast, and ran a structured process with a practical task: planning onboarding for a real (anonymised) customer. Before day one they completed the right to work check, issued a contract with IP and confidentiality clauses, registered for PAYE and set up auto-enrolment with a pension provider.

Common mistakes

• Hiring friends or the most available person rather than the best fit for the scorecard.
• Underestimating the full cost of a hire.
• Starting someone before right to work checks and contracts are done.
• No onboarding plan, so the new hire spends weeks working out what to do.

What to measure

• Time to hire and cost per hire.
• Progress against the first-year scorecard outcomes.
• Completion of compliance steps for every hire.
• Staff retention after the first year.
