First employee checklist for UK small businesses

Hiring your first employee is a major step. It can help you grow, delegate and professionalise the business — but it also brings new responsibilities. The exact requirements depend on how your business is structured and what the employee will do, so this checklist is designed as a practical starting point rather than a substitute for official guidance.

Before you hire, it is worth checking the basics of your business structure. GOV.UK notes that the way you set up a business affects tax and legal responsibilities, and that sole traders and limited companies operate differently in important ways.^{GOV.UK — Set up a business}

1. Confirm your business structure and employer position

If you are a sole trader, you can have employees, but you are personally responsible for the business debts of the business. If you run a limited company, the company is legally separate from you and may have different responsibilities around records, accounts and tax.^{GOV.UK — Set up a business GOV.UK — Set up a limited company}

Check:

• what business structure you are trading under
• whether you are already registered in the way required for that structure
• who will be the person responsible for managing payroll and employee records

Illustrative example: a sole trader hiring a part-time administrator may handle the employment personally, whereas a limited company may want to separate payroll administration from day-to-day management, even if the director remains legally responsible.

2. Make sure the role is clearly defined

Before advertising or offering the job, set out what the employee will actually do. A clear role profile helps with recruitment, performance management and budgeting.

Useful items to define

• job title and main duties
• hours, working pattern and location
• line manager
• pay structure
• start date
• whether the role is permanent, fixed-term or casual

This is also the right moment to think about whether the role needs additional permissions, licences or insurance depending on the work involved. GOV.UK says limited companies may need licences or permits, business insurance, and other checks depending on what the business does.^{GOV.UK — Set up a limited company}

3. Check whether you need to register or update tax arrangements

Businesses do not all have the same registration steps. For example, GOV.UK explains that a sole trader can start trading straight away without registering, but must register for Self Assessment as a sole trader if they earn more than £1,000 in a tax year. Limited companies must register before they start trading.^{GOV.UK — Set up a business}

Once you hire, you may also need to deal with payroll and other taxes. GOV.UK says that limited companies with employees have more responsibilities, including running payroll, paying National Insurance for employees, and providing workplace pensions to eligible staff.^{GOV.UK — Set up a limited company}

Check official guidance if you are unsure about:

• when to register as an employer
• how payroll should be set up
• which taxes apply to your business structure
• what records need to be retained

4. Put payroll, pay and record-keeping in place

Whatever your structure, hiring staff means more paperwork. GOV.UK says that directors of limited companies are responsible for keeping company and accounting records, checking Companies House information, and filing accounts and tax returns.^{GOV.UK — Set up a limited company} Even where an accountant or payroll provider helps, the director remains legally responsible.

If this is your first hire, make sure you have a simple but reliable process for:

• collecting employee details
• storing contracts and right-to-work documents where relevant
• recording pay, holidays and absences
• keeping evidence of payments and deductions

Illustrative example: a small design studio might use one folder for recruitment documents, one for payroll records and one for routine HR notes. The exact system matters less than consistency and secure storage.

5. Prepare the employment paperwork

You should have written terms ready before the employee starts. This is where you capture the practical details of the role, including pay, hours and notice arrangements. If you use templates, review them carefully so they match the actual job.

Documents to consider

• offer letter
• employment contract or written statement of terms
• job description
• starter checklist for your internal process
• policies such as holidays, sickness and expenses

Where legal guidance is not clearly covered by the sources you are using, check official GOV.UK guidance or take specialist advice before issuing final documents.

6. Think about workplace pensions and employee costs

Adding a first employee is not only about salary. GOV.UK notes that businesses taking on employees may need to provide workplace pensions to eligible staff, and that there are employee National Insurance responsibilities.^{GOV.UK — Set up a limited company}

You do not need to guess the numbers from memory. Instead, build a hiring budget that includes:

• gross pay
• employer on-costs where relevant
• pension contributions if applicable
• payroll software or bureau fees
• insurance and equipment costs
• training and onboarding time

Illustrative example: if you plan to pay £2,000 a month, the total employment cost may be higher once payroll, pension and other employer costs are included. The exact figure depends on your circumstances, so confirm the detail with official guidance or your adviser.

7. Check whether you need insurance, licences or permissions

Employee hiring often exposes gaps elsewhere in the business. GOV.UK says businesses may need licences or permits, business insurance and specific checks depending on what they do.^{GOV.UK — Set up a limited company}

Review whether you need to think about:

• employers’ liability or other business insurance
• sector-specific permissions
• data handling if the new hire will access personal information
• homeworking or office-space arrangements
• health and safety responsibilities

If the employee will work with customer data, online systems or confidential documents, set access controls before their first day.

8. Prepare the workplace and onboarding plan

Good onboarding saves time later. Even a small business benefits from a structured first week. That does not mean creating a corporate programme; it means removing avoidable confusion.

Onboarding checklist

• desk, laptop, software logins and email address
• introductory schedule for the first week
• contact list for key suppliers and internal contacts
• training on essential tasks
• explanation of holiday booking and reporting absence
• policy documents in one place

Illustrative example: a small online retailer might use day one to explain order processing, customer-service tone and stock procedures, then use the rest of the week for supervised practice.

9. Keep the comparison between business types in mind

If you are still deciding whether to trade as a sole trader or limited company, it helps to understand the difference before you employ someone. GOV.UK sets out key contrasts in liability, record-keeping, taxes and registration.^{GOV.UK — Set up a business}

This is not a tax planning table, just a reminder that structure affects the admin you need to prepare for.

10. Final pre-start check

Before your first employee begins, run through a final review:

• the role description is final
• pay and hours are agreed
• contracts and policies are ready
• payroll is set up or confirmed
• insurance and permissions have been checked
• equipment and access are prepared
• records are organised
• you know which points still need official guidance

Hiring your first employee should feel like progress, not panic. The key is to move step by step, keep records from the start, and verify the legal and tax details through official GOV.UK guidance whenever the position is unclear.

In short: define the job, confirm your structure, set up payroll and records, budget properly, and check any insurance or permit needs before day one.
