Natural HR is a UK-based HR software platform built for small and medium businesses that want cloud-based employee management. LeaveBalance is a dedicated leave management tool that matches Natural HR’s leave features while adding native Slack and Microsoft Teams integration — at a flat rate that does not scale with headcount.
Both tools handle leave requests, approvals, and balance tracking. The difference is scope and pricing: Natural HR is a broader HR platform with per-employee pricing, while LeaveBalance is a focused leave tool with flat-rate pricing.
If you are evaluating both, this comparison covers pricing, UK employment law compliance, integrations, and day-to-day experience.
Key Takeaways
- Natural HR charges £6–10 per employee per month; LeaveBalance charges a flat £10/month for unlimited employees

- LeaveBalance adds native Slack and Microsoft Teams integration — Natural HR does not
- At 25 employees, Natural HR costs £150–250/mo vs LeaveBalance at £10/mo
The Core Difference: Broad HR Platform vs Focused Leave Tool
Natural HR is a cloud-based HR platform for UK businesses:
- Employee records, absence management, document storage, and onboarding
- £6–10 per employee per month depending on plan
- UK-specific compliance features including statutory leave tracking
- Integrations with select payroll providers
LeaveBalance is a dedicated leave management tool:
- Flat-rate £10/month — unlimited employees, unlimited leave policies
- Native Slack and Microsoft Teams integration
- Configurable leave policies aligned with UK Working Time Regulations
- 14-day free trial, no credit card required
| Team Size | Natural HR (est.) | LeaveBalance |
|---|---|---|
| 10 employees | £60–100/mo | £10/mo |
| 25 employees | £150–250/mo | £10/mo |
| 50 employees | £300–500/mo | £10/mo |
| 100 employees | £600–1,000/mo | £10/mo |
At 25 employees, LeaveBalance is 15–25x cheaper. At 100 employees, the gap reaches 60–100x.
UK Employment Law Compliance
Natural HR’s Approach
Natural HR tracks statutory annual leave (5.6 weeks), statutory sick pay, parental leave, and other UK entitlements. It includes a holiday calculator, absence reporting, and configurable leave types. Natural HR also offers employment law guides and template documents to help you stay compliant.
LeaveBalance’s Approach
LeaveBalance supports configurable leave policies aligned with the Employment Rights Act 1996 and Working Time Regulations. You can configure annual leave, sick leave, parental leave, and any custom policies. Pro-rata calculations for part-time employees and accrual rules are built in.
Which Approach Suits You?
Natural HR gives you broader HR compliance tools alongside leave — document templates, employment law guides, and employee records. If you need a single system for HR compliance, Natural HR covers more ground. If leave management is your primary concern and you have other HR processes in place, LeaveBalance covers it at a fraction of the cost.
Slack and Microsoft Teams Integration
Natural HR
Natural HR does not offer native Slack or Microsoft Teams integration for leave management. Employees use the Natural HR portal to request leave, and managers approve through the web dashboard. Notifications are email-based.
LeaveBalance
LeaveBalance lives inside Slack and Microsoft Teams. Employees request leave with a slash command, managers approve with a button click, and balances update automatically. No portal login needed — the full workflow happens where your team already communicates.
This is the biggest difference in daily experience. If your team uses Slack or Teams, LeaveBalance removes the friction of switching to a separate tool.
What Each Tool Does
Natural HR Is an HR Platform
Natural HR covers employee records, absence management, document storage, onboarding, and employment law resources. It is a broader HR toolkit designed for UK small businesses.
The trade-off is cost. Every feature is included in the per-employee price, and teams that primarily need leave management end up paying for modules they do not use.
LeaveBalance Is a Leave Management Tool
LeaveBalance does one thing well: managing leave. Requests, approvals, balance tracking, team calendars, and analytics — all in Slack and Teams. No payroll, performance, recruitment, or document storage.
The benefit is simplicity and cost. Your team gets a purpose-built leave tool without feature bloat.
Reporting and Analytics
Natural HR provides absence reports, trend analysis, and exportable data. The reporting covers absence patterns and can help identify trends across your workforce.
LeaveBalance offers leave trend reports, utilisation rates, and payroll-ready data exports. The reporting is focused on what matters for leave management decisions.
For most small businesses, LeaveBalance’s reporting covers the essentials. If you need broader HR analytics across recruitment, performance, and absence together, Natural HR offers more comprehensive reporting.
The Honest Limitations
Where Natural HR Falls Short
- Per-employee pricing means costs grow with every new hire
- No Slack or Teams integration — requires a separate portal
- Feature bloat for teams that only need leave management
- Portal friction can reduce employee adoption
- Higher total cost than purpose-built leave tools
Where Leave Balance Falls Short
- No employee records or document storage — you need a separate HRIS
- No onboarding workflows or employment law template library
- No broader HR compliance tools like contract templates or handbooks
- Newer brand in the UK market compared to Natural HR’s established presence
- No phone support — email and chat based
Choose Natural HR If
- You need a single platform for employee records, documents, and leave management
- You want employment law guides and template documents alongside absence tracking
- Per-employee pricing is acceptable at your current and projected headcount
- You do not rely on Slack or Teams for daily communication
- You want broader HR functionality in one system
Choose LeaveBalance If
- You need dedicated leave management without paying for an HR suite
- Your team uses Slack or Microsoft Teams and wants leave requests inside those apps
- You want flat-rate pricing that stays the same as you grow
- Setup speed matters — operational in 15 minutes
- You already have HR processes and tools in place for records and documents
The Bottom Line
Natural HR is a solid UK-based HR platform that covers a range of small business needs — employee records, documents, onboarding, and absence management. For teams that need a broad HR toolkit, it delivers value.
But if leave management is your primary need and your team uses Slack or Teams, you are paying £6–10 per employee per month for features you may not touch. LeaveBalance covers leave management at a flat £10/month. At 50 employees, that is a saving of £290–490 per month.
Try LeaveBalance free for 14 days — no credit card required — and see whether it covers what your team actually needs. Most teams know within the first week.
