We’ll guide you through legal duties and onboarding essentials so you can follow best practice and grow your business – confidently and compliantly.
Here’s what to know before hiring your first employee in the UK, including information on contracts, payroll and right-to-work checks.
Key Takeaways
Complete all necessary legal steps before your employee starts, including HMRC registration, right-to-work checks, and drafting an employment contract.
Set up automatic pension enrolment and check whether your employee meets the eligibility criteria.
Onboard your new hire with clear goals and regular check-ins to build confidence, motivation, and long-term success.
How to know when to hire your first employee
The ideal time to hire your first employee depends on your business' specific needs.
If you’re struggling to keep up with customer demand, neglecting marketing, or missing out on networking opportunities, you might need to expand.

We’ll cover what to consider before you post your job ad.
Signs it’s time to expand
Knowing when to hire can be difficult, but there are a few things to keep an eye on to help you decide when to bring someone on board.
You’re regularly turning down work. Note whenever you decline projects or miss sales opportunities. That will help you understand when demand exceeds capacity.
You’re consistently working long hours. If overtime becomes necessary just to stay on top of daily operations, it’s a sign that your workload has outgrown a one-person setup.
Your response or delivery times are slipping. If your customers are waiting longer than usual for replies, quotes, or goods, you likely need extra support to maintain service quality.
You’re spending more time on admin than on growth. Are tasks like bookkeeping dominating your working day? If so, you may need to hire someone to free up your time to focus on strategy.
Your business needs specialist skills you don’t have. Bringing in an employee with expertise in areas like design, marketing, or finance can increase efficiency and improve results.
Hiring your first employee can sustain growth and protect your wellbeing, especially when you're reaching the limits of solo working. Tracking simple performance metrics can help you spot the right moment to expand.
What to consider before hiring your first employee
Before hiring, make sure you’re ready – financially, operationally, and mentally.
Check your budget can handle wages, National Insurance, and pension costs. The extra expense may be worthwhile if it frees up your time and creates room for growth.
Operationally, you need to ensure your systems are ready for collaboration. Are your core processes efficient? You’ll need to work with someone else now, so you may need to adjust how you perform certain tasks.
Finally, be open to sharing responsibility – growth requires trusting others.
Writing a clear job description will avoid confusion later. It can help you see what you need from a new employee.
Legal responsibilities when hiring your first employee in the UK
So, you’ve established that it’s the right time for you to hire your first employee, advertised the role and found the perfect candidate. Now, it’s time to complete a few essential legal steps.
Conduct right-to-work checks
You must confirm that your employee has the legal right to work in the UK.
Check and record an acceptable document, such as a passport, visa or share code (a unique code generated by the UK government that allows non-British and non-Irish citizens to prove their right to work).
Keep dated copies safely for two years after employment ends. You may need to show proof later, so keeping good records is essential.
You must register with HMRC before your employee’s first payday to pay tax and National Insurance contributions.
You can do this online. Once you register, you’ll receive a PAYE reference number which you’ll use to report employee earnings.
If you are already self-employed (for example, as a director of your limited company), you should already be registered.
Provide an employment contract and written particulars
Every employee must receive a contract (a legal agreement between an employee and their employer) and a written statement that outlines the role’s key details, including pay, hours, job title, and holiday entitlement. This is often referred to as “employment particulars” in legal documents. Sometimes, the written statement forms part of the contract. Other times, it’s a separate document. Either way, it’s a legal requirement.
You must provide your new employee with the written statement (also known as principal terms) by their first working day. You’ll also need to supply any additional details within two months.
Clear documentation protects both parties and sets expectations early, reducing the risk of misunderstandings. Consider getting legal advice when drafting your first contract.
Take out Employers’ Liability insurance
Employers’ Liability insurance protects your business if an employee becomes ill or injured at work. Your policy must cover at least £5 million, which is the legal minimum.
Keep your insurance certificate visible and up to date at all times. Failing to do so can result in fines.
Understand your automatic enrolment and workplace pension duties
When you hire your first employee, you’ll take on legal obligations around workplace pensions, known as automatic enrolment. These duties apply as soon as your first employee starts work, even if they’re not eligible for enrolment.
You’ll need to assess your employee’s age and earnings to see if they qualify for automatic enrolment. In simple terms:
If they’re aged between 22 and the State Pension age and earn more than £10,000 a year, you must enrol them into a workplace pension and make contributions.
If they earn less or fall outside that age range, they can still ask to join a pension scheme. You’ll need to arrange this if they do.
Rates and thresholds may change, so check GOV.UK for the latest information.
You’ll also need to:
Choose a qualifying pension scheme that meets minimum contribution requirements.
Write to your employee within six weeks of their start date to explain automatic enrolment.
Submit a declaration of compliance to The Pensions Regulator, confirming that you’ve met your duties.
Even if your new employee isn’t eligible for automatic enrolment, you must still complete the declaration.
Managing automatic enrolment can be straightforward once you’ve set it up correctly.
Key legal responsibilities for your first employee
To summarise, here’s a recap of the legal requirements we’ve discussed so far:
Requirement
What you need to do
Deadline or timing
Notes / extra detail
Right-to-work check
Verify acceptable documents (such as passports, visas, and share codes) and make copies with date stamps.
Before employment begins.
You must retain copies for the duration of your employment and for two years thereafter.
Register as an employer with HMRC
Sign up online with HMRC to receive an employer reference number.
Before your employee’s first payday.
You can’t register more than two months before you’ll pay your first employee.
Provide a written employment contract and statement of particulars
Issue a written contract and statement covering essentials (including hours, salary, holiday entitlements).
By the first working day (for contract and main statement), and within two months for broader statement.
The contract and main statement must be available by day one, with full particulars OK to follow later.
Employers’ Liability insurance
Obtain insurance covering at least £5 million.
Before the employee starts.
You must display or make the certificate available; failure to do so may result in a fine.
Workplace pension duties, including automatic enrolment
Assess automatic enrolment eligibility, enrol your employee into a qualifying pension scheme (if eligible), submit compliance to The Pensions Regulator
Duties begin from your first employee’s start date.
Even if no employee is eligible for a pension, you must complete a declaration of compliance.
Payroll and financial admin requirements
Once you’ve hired your first employee, you need to pay them.
As a solo founder, you’ll handle payroll yourself unless you use an accountant. Fortunately, plenty of tools can streamline payroll and reduce manual admin. Our accounting services can also help you simplify payroll.
Choose your payroll software or services
Payroll software helps you manage wages, pensions, and tax reporting. HMRC’s free Basic PAYE Tools software suits most first-time employers, but paid options like Xero or QuickBooks offer more automation and scalability as your business grows.
Most off-the-shelf payroll software costs between £30 and £80 per month, while an accountant’s monthly fee typically ranges from £60 to £450. The exact cost for payroll support will depend on your number of employees, frequency of pay-runs, and the level of support you

Understand taxes and benefits
By using PAYE (Pay As You Earn), you’ll deduct Income Tax and National Insurance from your employee’s pay and report that to HMRC each payday.
Once set up, payroll and HMRC reporting becomes a structured monthly process.
You may need to make occasional adjustments for other entitlements, such as statutory sick pay or maternity pay.
Ensure good record keeping (including payslips)
By law, you are required to provide your employees with payslips that show their gross pay, deductions, and net pay.
You’ll also need to keep payroll records for at least three years (after the end of the tax year). Make sure you store employee information securely and in line with GDPR.
Good record-keeping makes compliance and audits easier. Start these habits early.
Finding and selecting the right candidate
Meeting your legal duties is one thing, but finding the right person is just as important.
Start by clarifying what you need. Once you define the skills, hours, and mindset required, you can craft a targeted job advert that will attract the right candidates.
Write a job description
A strong job description sets the tone for your hire. When drafting yours, make sure to:
Outline the role’s main tasks, required skills, and working hours.
Be transparent about salary and benefits to attract serious applicants.
Clearly state essential qualifications.
Mention if you’re open to training or transferable skills to widen your talent pool and support inclusive hiring.
Specify whether the role is office-based, hybrid or remote.
Advertising a role with a well-written job description helps applicants know if they’re the right fit before they apply, saving everyone time during the hiring process.
Advertise the vacancy
You don’t need a big budget to find talent. Listing your job for free on platforms like Indeed, LinkedIn, and GOV.UK’s Find a Job service can connect you with suitable applicants quickly.
Local groups, such as Facebook communities, can also work well for some roles.
If your role sits within a specific field, try posting on relevant niche boards (such as Dribbble for design roles).
Always review your advert for inclusivity and compliance with equality law. For instance, avoid phrases like “young professional” for an entry-level role, as this could be perceived as discriminatory to older applicants.
Shortlist and interview effectively
Once applications start coming in, take your time to review them and pick the strongest candidates to interview.
Shortlisting tips
To shortlist well:
Look for potential rather than only perfect experience. Transferable skills can add real value in a small business.
Develop a straightforward scoring system to consistently evaluate candidates and minimise bias.
When you’ve built your shortlist, contact applicants to confirm their interest before arranging interviews.
Interviewing tips
Effective interviews focus on understanding how a candidate’s skills and values align with your business goals.
To get the most out of an interview:
Ask open-ended questions. Let candidates demonstrate how they think and work.
Avoid asking about personal circumstances or protected characteristics. For example, you should not ask a candidate if they are married or have children.
Remember that interviews go both ways – candidates are deciding whether they want to work with you, too. Stay professional yet approachable.
Consistency and fairness support good hiring decisions.
Onboarding your employee
Once you’ve chosen your new hire and completed all legal steps, you need to integrate them into your business.
Tech set up and documentation
A smooth onboarding experience builds confidence and sets a positive tone.
Before your employee’s first day, take practical steps like:
Setting up their company email address
Configuring software access
Gathering digital policy documents and training manuals
Asking them for any essential details, like emergency contact information
You can make a good first impression by showing how organised you are.
First-day essentials
Help your new employee settle in and give you both time to adjust. Begin with a welcome chat, explaining what to expect during their first week and covering essential health and safety basics.
Encourage questions – starting a new job is a lot to take in. You want them to feel part of your small business from the very start.
Give your new employee positive feedback at the end of their first day. It will help them feel supported.
Setting expectations and goals
Setting clear expectations from the start helps new employees understand what success looks like and how their work contributes to the business. Consider agreeing on short-term goals for their first 30, 60, and 90 days, covering essential tasks, training, and progress check-ins.
For example:
Day 1–30: Product walk-throughs, training, client introductions
Day 31–60: Task ownership, performance feedback, light mentorship
Day 61–90: Goal setting, performance check-in, long-term roadmap alignment
Maintaining regular communication can help you stay aligned refine objectives as the business evolves.
The right goal-based structure can build confidence, loyalty, and long-term productivity.
Mistakes to avoid when hiring your first employee
Hiring your first team member is a learning curve. Here are some common pitfalls to be aware of.
Compliance missteps
It’s easy to overlook small but important steps, such as confirming right-to-work status or registering with HMRC on time.
These mistakes can lead to delays, fines and even criminal prosecutions, so always double-check GOV.UK guidance before your new hire starts.
Rushing the recruitment process
It’s tempting to hire the first person available, especially when you’re busy. However, rushing can lead to mismatched expectations and them leaving, forcing you to start again.
Take time to review applications and interview multiple candidates. A short delay now can reduce disruption later.
Not documenting terms clearly
Handshake agreements may seem fine in a small business, but they rarely protect you in practice.
Always confirm key terms, such as pay, hours, and duties, in writing.
Clear documentation prevents confusion and builds trust from the start.
Make the right first hire
Hiring your first employee marks a significant step in your business journey. With the right preparation – legally, financially, and operationally – you’ll build a strong foundation for long-term growth.
From company formation to ongoing compliance support, Company Formations Direct offers expert resources to help you move forward with confidence.
Beyond meeting the legal basics, create a structured hiring plan that includes defining your job requirements, advertising widely (including on free job boards), and setting a consistent interview process. Document decisions and keep interview notes to help prove fairness and compliance if anyone ever reviews your hiring process.
Once you’ve hired your first employee, register with HMRC online using your Government Gateway account. You’ll need your company details and employee start date. Registration can take up to five working days, so allow enough time to avoid missing your first payroll deadline. After registering, keep the PAYE reference you’ll receive safe for future tax submissions.
Yes, and the contract must reflect statutory requirements and your business’s specific expectations. In addition to pay and hours, include clauses on confidentiality, notice periods, and probation. Templates are available online, but it’s worth having a solicitor review your first contract to ensure it’s legally sound.
To legally hire someone in the UK, you’ll need a written employment contract, Employers’ Liability insurance certificate and right-to-work documentation. You’ll also need to keep payroll records. You may also have to have health and safety policies, GDPR privacy notices, and workplace pension documents. Keeping all employee records organised from day one will make completing future audits a smoother process.
You can use HMRC’s free Basic PAYE Tools to run payroll or choose software like Xero or QuickBooks. Set clear pay dates, issue payslips, and ensure PAYE submissions are made on or before payday. Even for a single employee, payroll accuracy is crucial. HMRC penalties for late or incorrect filings apply to businesses of all sizes.
Your responsibilities as an employer extend beyond pay and taxes. You must ensure a safe workplace, protect personal data, provide statutory entitlements (such as sick pay and holidays), and comply with equality laws. Regularly reviewing GOV.UK guidance will help you stay compliant. Documenting your processes can keep things transparent and professional.
