When to Formalise Your HR
Many UK small businesses operate informally until they hit 10-15 employees, when the cracks start to show. Common triggers for setting up a proper HR system include:
- Inconsistent handling of leave requests
- Uncertainty about employment law obligations
- Difficulty tracking who is off and when
- Onboarding new joiners with no consistent process
- A dispute or grievance with no documented procedure to follow
The good news is that setting up a basic HR system does not require an HR department. With the right tools and policies, a founder, office manager, or finance lead can manage HR effectively for a team of up to 50 people.
Step 1: Establish Core Policies
At a minimum, every UK employer should have written policies covering:
Must-Have Policies
- Disciplinary procedure (must comply with the ACAS Code of Practice)
- Grievance procedure (must comply with the ACAS Code of Practice)
- Health and safety policy (required by law for 5+ employees)
- Equal opportunities policy
- Absence management policy
- Data protection / privacy notice for employees
Strongly Recommended
- Flexible working request procedure (legal obligation since April 2024)
- Whistleblowing policy
- Maternity, paternity, and parental leave policy
- Acceptable use of IT policy
- Social media policy
Policies should be written in plain English, practical, and proportionate to the size of the business. A 10-person company does not need 50-page policy documents.
Step 2: Choose HR Software
For UK small businesses, HR software should provide:
- Leave management with UK statutory holiday calculations
- Employee database with GDPR-compliant storage
- Absence tracking with Bradford Factor
- Document storage for contracts, right-to-work evidence, and fit notes
- Self-service portal for employees to request leave and update their details
- Onboarding workflows to ensure consistent new-joiner processes
Avoid overbuying. A small business does not need enterprise features like succession planning or 360 feedback on day one. Choose a system that covers the basics well and can grow with you.
Step 3: Set Up Employee Records
For each employee, collect and store:
- Signed employment contract
- Right-to-work evidence (with check date recorded)
- P45 or starter checklist
- Bank details for payroll
- Emergency contact details
- Pension auto-enrolment records
- Any medical information relevant to their role
All records must be stored securely with access restricted to those who need it.
Step 4: Configure Leave Management
- Define your holiday year (calendar year, April-March, or employee anniversary)
- Set entitlements by contract type (full-time, part-time, zero-hours)
- Decide on bank holiday treatment (included in or additional to statutory entitlement)
- Set carry-over rules (UK statutory minimum allows up to 1.6 weeks to carry over)
- Configure approval workflows (who approves leave requests)
Step 5: Build Your Onboarding Process
Create a repeatable checklist covering:
- Pre-start tasks (contract, right-to-work, IT setup)
- Day-one activities (welcome, tour, system access)
- First-week training
- 30/60/90-day check-ins
Step 6: Set Up Absence Management
- Define reporting procedures (who, when, how to report sickness)
- Configure Bradford Factor thresholds if using them
- Set up return-to-work interview templates
- Enable fit note tracking and reminders
Step 7: Train Your Managers
Line managers are the frontline of HR in a small business. They need to understand:
- How to approve and manage leave requests
- The absence reporting and management process
- Basic disciplinary and grievance procedures
- How to conduct return-to-work interviews
- Their legal obligations (equality, data protection)

Frequently Asked Questions
At what size does a business need HR software?
There is no legal requirement, but practically, most businesses find they need HR software around 10-15 employees. Below that, spreadsheets and manual processes are manageable. Above it, the risk of errors, missed compliance requirements, and wasted time increases significantly.
Can I manage HR without a dedicated HR person?
Yes. Many UK businesses up to 50 employees manage HR effectively without a full-time HR person, using HR software to automate processes and outsourcing complex issues (like tribunal claims or restructuring) to HR consultants. A founder, office manager, or finance director typically takes on the HR responsibility.
What are the first HR policies I should create?
Start with a disciplinary procedure, grievance procedure, absence management policy, and health and safety policy. These cover your legal obligations and the situations most likely to arise. Add further policies as needed as your business grows.
