HR software has quietly become one of the highest value purchases a growing UK business can make, because the alternative is a holiday spreadsheet, a folder of contracts and a nagging worry about compliance. The right platform gives you leave management, employee records, onboarding and performance in one place, and lets people self serve rather than emailing whoever runs HR.
The UK market splits cleanly by size. Small businesses want something simple and predictably priced, while mid sized and fast growing companies need performance, analytics and multi country capability. We have ranked the leading options across that whole range, so there is a genuine recommendation whether you are ten people or five hundred.
What to look for in UK HR software
The foundation of any HR platform is leave and absence management, employee records and documents, and correct handling of UK statutory entitlements. If a tool cannot make the holiday spreadsheet disappear and hold your records securely, nothing else matters. From there, the needs diverge sharply by company size.
Smaller businesses should prioritise simplicity and predictable pricing, and watch whether a tool charges per employee or a flat fee per company, because that decides how cost behaves as you hire. Growing and mid sized companies will want performance management, applicant tracking and analytics, and should check how far a platform scales before they invest in configuring it. If you operate in more than one country, multi country capability rules out most purely UK tools. And remember that most HR platforms do not include payroll, so confirm the integration with whatever payroll you run.
How we assessed these tools
Every product here was judged on the things that actually decide whether software works for a UK business: the real published price excluding VAT, how it handles HMRC obligations such as Making Tax Digital, RTI or CIS where relevant, the depth of the core job it is bought for, how quickly a non specialist can get productive, and the quality of UK support. We read each vendor's own pricing pages rather than repeating third party figures, and we weight verified user ratings from people who run these tools day to day.
We also try to be honest about fit rather than crowning a single winner, because the right tool for a ten person business is rarely the right tool for a two hundred person one. Each entry below carries its real starting price, its current Assaylist rating and a clear note on who it suits and where it falls short, so you can match the software to your own situation rather than to an average. Where we earn a commission from an outbound link we say so, and it never changes the order of this list.
The best options ranked
1. Breathe
Breathe is the tool that retires the holiday spreadsheet for a UK small business, and its flat per company pricing means hiring does not push the cost up. It is simple enough that a non specialist runs it without training, and being UK built the statutory leave handling just works.
What you get: A UK built HR platform aimed squarely at small businesses, with flat per company pricing by headcount band. Popular for replacing the holiday spreadsheet without a big commitment. It holds a 4.1 out of 5 rating across 373 reviews on Assaylist.
Pricing: The plans run Micro at £24, Starter at £44, Regular at £99 and Pro at £175 per month, excluding VAT.
Why we rate it:
- Flat per company pricing, not per employee
- Simple enough for a non specialist
- UK built for UK small businesses
- Predictable band based cost
Bear in mind: it is deliberately simple, so larger or more complex teams will outgrow it.

2. CharlieHR
CharlieHR comes from the London startup world and it shows in a clean, quick experience that small teams actually adopt. Its optional HR advice line is a genuine differentiator for a company with no HR function, giving real guidance at exactly the moments that carry risk.
What you get: A London built HR platform for small and growing teams, with headcount band pricing and a paid HR advice add on for companies without an HR function. It holds a 4.0 out of 5 rating across 498 reviews on Assaylist.
Pricing: The plans run Core (1 to 4) at £20, Core (5 to 14) at £45 and HR Advice add on at £179 per month, excluding VAT.
Why we rate it:
- Polished experience built for startups
- Optional real HR advice line
- Affordable for the smallest teams
- Quick to set up
Bear in mind: the advice and recruitment add ons need an active core plan, so the full package costs more.

Access PeopleHR sits a rung above the simplest tools, with graduated tiers that add performance management, applicant tracking and analytics as you climb. Backed by the Access Group, it connects to a wider finance and payroll ecosystem, which matters if you are standardising on one vendor.
What you get: Part of the Access Group, aimed at small and mid sized UK businesses that have outgrown the simplest tools. Per employee pricing across four tiers. It holds a 4.0 out of 5 rating across 308 reviews on Assaylist.
Pricing: The plans run Starter at £3, Core at £5.5, Pro at £8 and Elite at £9.5 per user per month, excluding VAT.
Why we rate it:
- Graduated tiers with room to grow
- Applicant tracking and performance built in
- Backed by the Access Group
- Per employee pricing from £3
Bear in mind: per employee pricing adds up faster than a flat per company rival at the same size.

BambooHR is genuinely pleasant to use, and adoption is one of the hardest problems in HR software, so a system people willingly log into is worth a lot. Its onboarding and self service are particularly strong for a growing company hiring steadily.
What you get: A widely used HR system, American built but common in UK growing companies, known for a clean experience across records, onboarding, performance and reporting. It holds a 4.0 out of 5 rating across 290 reviews on Assaylist.
Pricing: The plans run BambooHR at a quoted price per user per month, excluding VAT.
Why we rate it:
- Excellent user experience and adoption
- Strong onboarding
- Large integration marketplace
- Breadth for a growing company
Bear in mind: pricing is quoted and UK statutory specifics are worth confirming, given its US roots.

HiBob, known as bob, is the platform for the modern culture focused company, with engagement and people analytics that go well beyond administering leave. It flexes to less conventional org structures and gives people teams the board level data they increasingly need.
What you get: A design led HR system popular with fast growing tech and professional services firms, strong on engagement, culture and analytics. Sold on quote. It holds a 4.1 out of 5 rating across 368 reviews on Assaylist.
Pricing: The plans run HiBob (bob) at a quoted price per user per month, excluding VAT.
Why we rate it:
- Design led and high adoption
- Strong engagement and culture features
- Good people analytics
- Flexible for modern org structures
Bear in mind: it is a premium quoted product, so more platform and cost than a small team needs.

Personio is the European choice for a mid sized business, built around structured process for the whole employee lifecycle. Its real strength is running the UK alongside other European countries in one system, which rules out purely UK or purely US tools.
What you get: A German built HR system designed for mid sized European businesses, covering the full employee lifecycle with a focus on structured process and multi country compliance. It holds a 4.0 out of 5 rating across 329 reviews on Assaylist.
Pricing: The plans run Personio at a quoted price per user per month, excluding VAT.
Why we rate it:
- Strong multi country capability
- Process driven and structured
- Good recruitment and onboarding
- Built for mid sized companies

7. Sage HR
Sage HR lets you start with leave management and add performance, timesheets or shift scheduling as modules when you need them, which suits a growing budget. The mobile app means site based staff actually submit requests, and it connects to Sage Payroll.
What you get: Sage's mid range HR platform, priced from £5 per employee per month for core leave management with paid modules added on top. It holds a 4.1 out of 5 rating across 293 reviews on Assaylist.
Pricing: The plans run Core Sage HR and Leave Management at £5, Performance management at £2.5, Timesheets at £2.5, Shift scheduling at £2.5, Expenses at £1.25 and Recruitment at £184.45 per user per month, excluding VAT.
Why we rate it:

How much should you budget?
HR software pricing splits into two models. Flat per company plans, such as Breathe, start around twenty four pounds a month and rise by headcount band, which keeps cost predictable as you hire. Per employee plans, such as Access PeopleHR, run from roughly three to ten pounds per person per month, which is cheaper when small and more expensive at scale. Premium platforms such as HiBob and Personio are quoted individually and sit at the higher end.
Model the cost at your expected size, not just today, because the two pricing models cross over as you grow. A per employee plan that looks cheap at ten people can cost more than a flat plan at fifty. And remember that payroll is usually a separate subscription, so budget for both if you need them.
Our verdict
For a UK small business, Breathe and CharlieHR are the two to shortlist, with Breathe winning on predictable pricing and CharlieHR on the optional advice line. As you grow past fifty people, Access PeopleHR and BambooHR offer the performance and analytics depth that the simplest tools lack.
At the top end, HiBob is the choice for a culture led company that will invest in configuration, and Personio is unmatched when the UK is one of several countries you operate in. Match the platform to your size and your ambition, and price the specific modules or tiers you actually need rather than the headline figure.
The bottom line
For most UK businesses the choice comes down to size. Small teams should shortlist Breathe and CharlieHR, growing companies Access PeopleHR and BambooHR, and culture led or international businesses HiBob and Personio. Price the specific modules or tiers you actually need rather than the headline, take the free trials, and choose something you can grow into so you are not replacing your HR system in the middle of a hiring spurt.
Frequently asked questions
What is the best HR software for a UK small business?
Breathe is the best choice for most UK small businesses, thanks to simple flat per company pricing and easy setup. CharlieHR is an excellent alternative for startups, especially those that value its optional HR advice line for companies without a dedicated HR function.
How much does HR software cost in the UK?
Small business HR tools range from around twenty pounds a month for a flat per company plan such as Breathe, up to per employee pricing of roughly three to ten pounds per person on platforms such as Access PeopleHR. Mid market and enterprise platforms such as HiBob and Personio are quoted individually.
Does HR software include payroll?
Usually not in the same subscription. Most HR platforms connect to a separate payroll product rather than including it. Employment Hero and Sage are exceptions that offer payroll alongside HR. If you want both, check whether the HR tool integrates cleanly with your chosen payroll.
What should HR software do for a UK business?
At minimum it should manage annual leave and absence, hold employee records and documents securely, handle UK statutory leave correctly, and let staff self serve. Growing businesses will also want onboarding, performance management, applicant tracking and reporting, which the mid market platforms provide.
Is HR software worth it for a small business?
For most businesses past around ten employees, yes. The time saved on leave management and admin, plus the reduced compliance risk from handling records and statutory leave correctly, typically outweighs the modest cost within the first year.
