HR Software in the UK: Systems, Apps and Platforms Explained

Choosing the right HR solution can feel overwhelming. From HR systems to HR apps and HR platforms for small businesses, the market is full of options. Each serves a slightly different purpose, but all aim to simplify people management, reduce admin and support compliance.

HR systems

An HR system is typically a full-featured piece of HR management software. It centralises employee records, automates compliance reminders, and integrates with payroll. For UK businesses, this means accurate HMRC submissions, right-to-work checks, and GDPR-compliant data storage.

Best for: businesses needing a comprehensive solution that scales as they grow.

HR apps

An HR app is a mobile-first tool that gives employees and managers quick access to HR functions on the go. Staff can view payslips, request leave, and update personal details directly from their phones.

Best for: teams that value flexibility, hybrid working, and employee self-service.

HR platforms for small businesses

Smaller companies often need a simpler, more affordable solution. HR platforms for small businesses focus on core functions like absence management, payroll integration and compliance reminders, without the complexity of enterprise-level software.

Best for: SMEs that want to save time and stay compliant without overspending.

HR software for small businesses in the UK

Startups and small companies in the UK face the same compliance demands as larger firms, but with fewer resources. HR software for small businesses offers cost-effective plans, often starting at just a few pounds per employee per month, making it accessible even for micro-businesses.

Best for: startups and growing SMEs looking to professionalise HR early.

How to decide what’s right for your business

1. Size of your team – smaller businesses may only need an HR platform, while larger ones benefit from full HR systems.

2. Budget – cost per employee varies, so look for transparent pricing.

3. Integration needs – payroll, accounting, and performance management tools should connect smoothly.

4. Flexibility – consider whether your team needs mobile access through an HR app.
