HR Tools Every UK Small Business Needs
The essential HR toolkit for UK small businesses: payroll software, contract tools, absence tracking, and pension platforms. Free options and what's worth paying for.
The HR toolkit for a small business does not need to be complex or expensive. The essential tools cover payroll, records, pension, and absence management. Everything beyond that is optional until you reach a size where the complexity justifies the cost.
The Essential Toolkit
1. Payroll Software
Payroll is non-negotiable. You must run payroll accurately and submit Real Time Information data to HMRC on or before every payday. This is a legal requirement from your first employee.
Free option: HMRC Basic PAYE Tools. Works for up to 9 employees. Handles gross to net calculations, payslip generation, and RTI submissions. Not pretty, but legally compliant. Download from GOV.UK.
Paid options worth considering:
| Software | Approximate Monthly Cost | Best For |
|---|---|---|
| Xero Payroll | £5-10/month add-on | Businesses already on Xero accounts |
| QuickBooks Payroll | £4-8/month add-on | Businesses already on QuickBooks |
| BrightPay | From £5/month | Standalone payroll, strong UK focus |
| FreeAgent Payroll | Included in FreeAgent | Freelancers, very small businesses |
| Sage Payroll | From £7/month | More established businesses |
If you use accounting software, use the same provider's payroll module if possible. The integration between your accounts and payroll saves time and reduces reconciliation errors.
2. Employment Contract Templates
Every employee must have a written statement of employment particulars from day one. You need a reliable, legally current template.
Free starting point: ACAS and GOV.UK both provide guidance on what a contract must contain. This is sufficient for drafting your own.
Better approach: Commission a solicitor or specialist employment law firm to draft a standard employment contract for your business. Cost: £200-600 one-off. This gives you a template that is specific to your working arrangements, sector, and jurisdiction, with post-employment restrictions if relevant.
Use a document management tool (even Google Drive or SharePoint) to store signed contracts. You must be able to produce a copy if asked.
3. Right to Work Record System
Right to work checks must happen before employment starts. You need a reliable system for:
- Conducting and documenting the check
- Storing a copy of the evidence
- Tracking expiry dates for time-limited permissions
Free approach: A folder per employee in your document management system, with a checklist confirming the check was completed and dated.
Software approach: Most HR information systems include right to work tracking with expiry alerts. This becomes valuable when you have 20+ employees and cannot manually track document expiry dates.
GOV.UK's Employer Checking Service is free and mandatory for some non-UK nationals. The Home Office share code service handles online checks for eligible workers.
4. Workplace Pension Platform
Auto-enrolment is mandatory. You need a qualifying pension scheme.
Free default: Nest (National Employment Savings Trust) is the government-backed workplace pension scheme. Free to set up as an employer, no minimum size requirement, accepts all UK employers. Contributions are managed through the online portal, and most payroll software can submit contributions automatically to Nest.
Alternative providers: People's Pension and Smart Pension are also widely used by small businesses. All three are auto-enrolment compliant.
The Pensions Regulator's website (thepensionsregulator.gov.uk) has step-by-step guidance and free tools for setting up and managing auto-enrolment compliance.
5. Holiday and Absence Tracking
Every employee is entitled to a minimum of 5.6 weeks' paid holiday per year (28 days for a full-time worker including bank holidays). Tracking entitlement, requests, and remaining balance is essential.
Free approach (up to 10 employees): A shared spreadsheet. GOV.UK provides a free holiday entitlement calculator that handles part-time and irregular hours correctly.
Paid approach: Almost every HR software platform includes holiday management as a core feature. Employees submit requests via an app; you approve or decline. Balances update automatically. Worth paying for once the spreadsheet approach requires more than 30 minutes per month to maintain.
6. Employee Records System
You need to store employee personal information, contracts, right to work evidence, absence records, and correspondence securely.
Free approach: A cloud folder system (Google Drive, SharePoint, Dropbox) with a consistent structure per employee. Label folders clearly and restrict access.
Paid approach: A basic HR information system centralises this, adds search functionality, generates reports, and typically includes an employee self-service portal. Cost: £2-8 per employee per month.
GDPR requirement: Whatever system you use, you must store employee personal data securely, limit access, and have a retention policy. Employee data should only be accessible to those who need it.
Tools You Probably Do Not Need Yet
Performance management software: Useful at 25+ employees. Before that, structured 1:1 conversations and a simple shared document are more effective than dedicated software.
Learning management systems (LMS): Relevant if you have mandatory training requirements (e.g., food safety, health and safety). For most small businesses, ad-hoc training records in a spreadsheet are sufficient.
Recruitment software (ATS): An applicant tracking system makes sense when you are managing multiple open roles simultaneously. Below 20 employees with occasional hiring, managing applications by email and spreadsheet is adequate.
Engagement survey tools: Valuable at 30+ employees. Below that, direct conversations are more effective and less expensive.
Building Your Stack Progressively
| Stage | Essential | Optional |
|---|---|---|
| 1-5 employees | HMRC Basic PAYE Tools, Nest pension, contract templates, Google Drive | Nothing else |
| 5-15 employees | Paid payroll software, HR information system basics | HR outsourcing for complex cases |
| 15-30 employees | Full HR platform with holiday/absence/records | Performance tools, ATS |
| 30-50 employees | Integrated HR and payroll platform | Learning management, engagement tools |
Do not invest in tools you do not have processes for. Software does not fix broken processes - it automates them, broken or not.

Frequently Asked Questions
- What HR tools does a small business need?
- Every UK small business needs: payroll software (or HMRC's free Basic PAYE Tools), employment contract templates, a right to work record system, a workplace pension platform, and an absence tracking method. Most businesses of 10+ employees also need a basic HR information system to centralise employee records and manage holiday requests.
- What free HR tools are available for UK small businesses?
- Free tools include: HMRC Basic PAYE Tools (payroll, up to 9 employees), Nest pension scheme (free for employers), GOV.UK contract templates and checklists, ACAS policy templates, and GOV.UK's holiday entitlement calculator. Some HR platforms offer limited free tiers (Factorial, Zoho People). These free tools cover the legal requirements for most micro-businesses.
- What payroll software do UK small businesses use?
- Popular payroll software for UK small businesses includes Xero Payroll, QuickBooks Payroll, BrightPay, Sage Payroll, and FreeAgent. For very small teams (under 10 employees), HMRC's free Basic PAYE Tools works. Most accounting software platforms include payroll as an add-on, which makes integration easier.
- Do you need a HR information system as a small business?
- Not immediately. At 1-10 employees, a well-organised shared drive with employee folders can work. At 10-20 employees, the administrative burden of tracking holiday, absence, and records manually becomes significant enough that a basic HRIS (HR information system) pays for itself in time saved. Most cost £2-8 per employee per month.
