How much does HR software cost in the United Kingdom?
Reviewed by Mellow Editorial Team, HR & payroll content team
HR software in the UK typically costs between £3 and £15 per employee per month for core HR functionality, though prices range from free (for very small teams) to well over £50 per employee per month for enterprise suites with payroll, compliance and analytics built in.
What drives the price difference
Pricing varies because "HR software" covers a wide range of tools. A basic system might handle only employee records and holiday tracking. A comprehensive platform can include payroll processing, auto-enrolment pension management, absence and performance management, onboarding workflows, and real-time reporting.
The main factors that affect your quote:
- Number of employees. Most vendors charge per head per month. The unit rate usually falls as headcount rises, so a 200-person company will pay less per employee than a 10-person one.
- Modules selected. Payroll processing is the most expensive add-on. If you run payroll in-house through the software rather than using a bureau, expect to pay more.
- Contract length. Annual contracts cost less per month than rolling monthly ones. Many vendors require a minimum commitment.
- Implementation and setup fees. Some charge a one-off fee to migrate your data and configure the system. This can run from a few hundred to several thousand pounds depending on complexity.
- Support tier. Dedicated account management or phone support often sits behind a higher pricing band.
Typical price brackets
Free and very low cost (£0–£2 per employee/month)
Tools like Breathe HR's starter tier or open-source options exist for micro-businesses. They are usually limited to absence tracking, document storage and basic reporting. Payroll is rarely included.
Mid-market (£3–£10 per employee/month)
This is where most small and medium UK businesses land. Products in this range — including BambooHR, Sage HR, Personio and Hibob — typically cover the full employee lifecycle: onboarding, absence, performance, and some reporting. Payroll integration varies; it may be a native module or a paid connection to a separate payroll tool.
Full HR and payroll suites (£10–£25 per employee/month)
Platforms that handle payroll natively, including RTI submissions to HMRC, pension contributions, P60 and P11D production, and statutory payments, sit in this band. For a business with 50 employees, that is roughly £6,000–£15,000 per year before any setup costs.
Enterprise (£25+ per employee/month or custom pricing)
Workday, SAP SuccessFactors and Oracle HCM are in this category. Pricing is almost always negotiated and includes implementation projects that can cost tens of thousands of pounds.
The hidden costs worth checking
The headline per-employee rate rarely tells the full story.
- Payroll bureau or managed payroll fees. If the software connects to an outsourced payroll bureau rather than running payroll natively, you may pay both the HR platform fee and a separate payroll processing charge.
- Integration costs. Connecting HR software to your accounting system, ATS or benefits platform sometimes requires a paid API connector or custom development work.
- Training. Vendors often include a set number of training hours; beyond that, additional sessions are charged separately.
- Price increases on renewal. Check whether your contract caps annual price rises. Some vendors have raised rates significantly at renewal in recent years.
What UK employers actually need the software to do
Before comparing prices, it is worth being clear about which legal and operational requirements your software must support.
At minimum, UK employers need to process payroll accurately, submit Full Payment Submissions (FPS) to HMRC on or before each payday under RTI, manage auto-enrolment contributions (employer minimum 3%, employee 5% of qualifying earnings), issue P60s by 31 May and P11D forms by 6 July where applicable, and track the statutory 5.6 weeks' annual leave entitlement.
The Employment Rights Act 2025 also extends day-one rights for employees, which increases the administrative value of software that keeps clean, timestamped employment records from the moment someone joins.
If your software cannot handle these requirements natively, factor in the cost of whatever fills the gap — a payroll bureau, a separate pension submission tool, or manual spreadsheet processes with the compliance risk that carries.
How to get an accurate quote
Most UK vendors do not publish pricing for teams above 50–100 employees; you have to request a demo. When you do, ask for:
1. The all-in monthly cost including any payroll module, not just the HR platform fee.
2. A written breakdown of implementation and data migration costs.
3. Whether the quote includes pension filing and RTI submission or whether those are extras.
4. The minimum contract term and what happens to pricing at renewal.
Getting two or three comparable quotes on that basis will give you a genuine like-for-like comparison rather than a lowest-headline-number race.
