Best Free HR Software UK 2026: What You Get and What You Give Up

Home › Business Software › HR Software › Free HR Software UK 2026

Last Reviewed: April 2026 | Fact-checked against ICO, ACAS, and HMRC guidance.

TL;DR: Genuinely free HR software for UK businesses is limited to freemium tiers capped at 5-10 employees with basic functionality, HMRC's Basic PAYE Tools for payroll RTI submission, and ACAS template employment contracts. Free tiers exclude the UK compliance features most employers need: auto-enrolment support, payroll integration, UK GDPR audit trails, and Bradford Factor absence tracking. This guide explains what free options genuinely provide and where they fall short.

How We Assessed These Platforms

We assessed free and freemium HR options against UK-specific criteria: genuine zero-cost availability without requiring payment details, employee cap on the free tier, features included in the free tier versus those withheld to drive upgrade, UK GDPR compliance of the free tier including Data Processing Agreement availability, payroll integration capability in the free tier, and G2/Capterra ratings above 4.0 from verified users of the free tier specifically. We also assessed the ICO compliance implications of free-tier data handling for UK employers. No platform paid to appear here.

Why Most HR Software Lists Get It Wrong for UK Businesses

Global lists of free HR software are written for an international audience and frequently include tools that are free in the US or globally but either unavailable in the UK, non-compliant with UK employment law, or structured around US compliance frameworks (W-2 payroll, FMLA leave, at-will employment) that do not translate to UK requirements. UK employers searching for free HR software need tools that handle Working Time Regulations holiday entitlement, provide a Data Processing Agreement under UK GDPR Article 28, and either include or integrate with HMRC-recognised payroll tools. These requirements exclude the majority of globally-promoted free HR tools from consideration for UK employers (CIPD, 2024).

What Does "Free" Actually Mean in HR Software?

Free HR software in practice takes three forms. Freemium tiers are the most common: a permanently free tier with a user cap (typically 5 users) and significantly limited features, designed to demonstrate value and drive upgrades. These are genuinely free but the employee cap and feature exclusions make them unsuitable for most operational HR use beyond a very early-stage business. Free trials are time-limited access to the full paid product, typically 14-30 days - not genuinely free, but useful for evaluation. Open-source HR software - OrangeHRM being the most common example - requires self-hosted infrastructure, technical implementation resource, and ongoing maintenance, which makes its true cost significantly higher than the zero licence fee suggests for most small UK businesses.

Free HR Software and UK GDPR: The Compliance Risk

Free HR software creates a specific UK GDPR compliance risk that paid platforms do not. As data controller, the UK employer must have a signed Data Processing Agreement under UK GDPR Article 28 with any software provider processing employee personal data. Free tier vendors sometimes provide DPAs only to paying customers, or provide DPAs that cover paid tier data processing but exclude free tier deployments from the same contractual protections. Before entering any employee personal data into a free HR tool, request the DPA and confirm it covers free tier users. If the vendor cannot or will not provide a DPA for free tier users, the employer is processing employee data through an uncontracted processor in violation of UK GDPR (ICO, 2024).

Free platforms also raise a secondary concern: the business model of a free platform. If the service is free, the product may be the user's data - specifically, aggregated workforce analytics, industry benchmarking data, or advertising targeting data derived from the employee records you load into the system. Review the vendor's privacy policy carefully before loading employee personal data into any free tier, and confirm that employee data is not used for purposes beyond providing the contracted HR service.

Genuine Free HR Software Options for UK Businesses 2026

HMRC Basic PAYE Tools: The Free Payroll Baseline

HMRC's Basic PAYE Tools is a free, HMRC-maintained payroll tool for employers with fewer than 10 employees. It handles: HMRC RTI Full Payment Submission on or before each payday; P60 generation at year end; P45 generation on employee departure; Starter Declaration (formerly P46) for new starters; and basic payslip generation. It does not include: automatic National Minimum Wage rate checking, integrated auto-enrolment pension assessment, or advanced payroll features for complex pay structures. For businesses with under 10 employees and straightforward PAYE payroll, Basic PAYE Tools covers the legal minimum at zero cost (HMRC, 2024).

Pair Basic PAYE Tools with ACAS's free employment contract templates and BreatheHR's 14-day free trial (or Zoho People's free tier for under 5 employees) to cover the minimum HR compliance obligations of a very early-stage UK business at minimal cost.

When Free Becomes the Wrong Choice

Free HR software becomes the wrong choice at three specific points. First, when employee count exceeds the free tier cap - at that point the free tier is no longer available and you are either paying for a tier you did not budget for or operating without a system. Second, when a UK GDPR Data Subject Access Request is received and the free tier cannot generate a complete, auditable export of all employee data in a reasonable timeframe. Third, when an absence or holiday calculation dispute arises and the free tier's record-keeping does not provide the evidence trail to resolve it. At any of these three points, the cost of the compliance gap significantly exceeds the cost of a paid tier that would have prevented it.

Frequently Asked Questions

Is there genuinely free HR software for UK small businesses?

Yes, but with significant limitations. Zoho People's free tier covers up to five users with basic records and leave management. Factorial's free plan is available with limited features for unlimited employees. HMRC's Basic PAYE Tools covers payroll RTI submission for under 10 employees at zero cost. None of these options provides the full compliance coverage - auto-enrolment, Bradford Factor, GDPR audit trails, payroll integration - that a growing UK business needs. They are appropriate starting points for very early-stage businesses, not long-term solutions.

Is HMRC Basic PAYE Tools good enough for small UK business payroll?

For businesses with under 10 employees with straightforward salary or hourly PAYE payroll, yes. HMRC Basic PAYE Tools handles RTI submission, P60 and P45 generation, and starter declarations. It does not handle: complex pay structures with commissions or bonuses; CIS subcontractor deductions; auto-enrolment pension assessment; or payroll for 10 or more employees without becoming unwieldy to manage. Beyond 10 employees or simple payroll, dedicated payroll software is the practical standard.

Do free HR software platforms provide a GDPR Data Processing Agreement?

This varies by platform and must be verified before loading employee data. UK GDPR Article 28 requires a signed DPA regardless of whether the software is free or paid. Some free tier providers include DPA coverage; others provide DPAs only to paying customers. Request the DPA explicitly before uploading any employee data. If the vendor cannot provide a DPA that covers free tier users, you cannot lawfully use that platform for employee personal data under UK GDPR.

What are the risks of using free HR software for employee data in the UK?

The risks of free HR software for employee data include: absence of a Data Processing Agreement creating a UK GDPR Article 28 violation; data storage in non-EEA locations without appropriate safeguards; limited audit trail capability that makes DSAR responses incomplete; feature limitations that create holiday calculation errors; and the business model risk that aggregated employee data may be used for purposes beyond providing the HR service. Review the DPA availability and privacy policy before loading any employee personal data.

What is the cheapest paid HR software for a UK business?

The lowest-cost paid HR platforms with meaningful UK compliance coverage are: Zoho People Essential tier at £1.25 per employee per month (EEA data residency, limited UK payroll); Factorial standard plan from approximately £5 per employee per month (EEA data residency); and BreatheHR Starter at £18 per month flat for up to 10 employees (UK data residency, ACAS-aligned templates). At 5 employees, BreatheHR Starter at £18 per month flat is cheaper than Zoho People at £6.25 per month for 5 employees. At 15 employees, Zoho People Essential at £18.75 per month is cheaper than BreatheHR Starter at £18 per month which covers only up to 10 employees at that tier.
