Payroll is the one piece of business software where getting it wrong is immediately expensive and immediately visible, because your staff notice the moment their pay is late or short. UK payroll also carries a heavy compliance load: real time submissions to HMRC on or before payday, pension auto enrolment, and legislation that changes every April without fail.
The right choice depends heavily on who runs it. A payroll bureau processing dozens of clients needs something very different from a small business owner running a monthly pay run themselves. We have ranked the leading UK payroll tools with that split in mind, on real pricing, compliance depth and how forgiving they are to run.
What to look for in UK payroll software
Compliance is non negotiable in payroll. Your software must submit Real Time Information to HMRC on or before payday, handle pension auto enrolment including the periodic assessment of staff, and update automatically for the legislative changes that arrive every April. Every product we recommend does all of this, so treat it as the entry ticket rather than a differentiator.
The real decision is about who runs payroll and how complex it is. A business owner running a small monthly pay run wants something forgiving with helpful error checking, whereas a payroll bureau processing many clients needs batch workflows and depth. Look closely at how many employees are included in the headline price and what each additional employee costs, because the advertised figure often understates the real bill. Finally, consider whether payroll should sit inside your accounting software, since posting the payroll journal automatically saves a monthly reconciliation and removes a common source of error.
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. BrightPay
BrightPay is what a huge share of UK accountants and payroll bureaus actually use, and for good reason. It is deep, reliably ready on day one of every new tax year, and its multi employer workflows are built for processing many payrolls from one place. If payroll is your job rather than a monthly chore, this is the specialist's choice.
What you get: A long standing favourite of UK and Ireland payroll bureaus, now moving fully to the cloud for the 2026/27 tax year. Deep, HMRC recognised, and built for people who run payroll for a living. It holds a 4.0 out of 5 rating across 219 reviews on Assaylist.
Pricing: The plans run BrightPay Cloud at a quoted price per month, excluding VAT.
Why we rate it:
- Trusted by a large share of UK bureaus
- Ready on day one of each tax year
- Strong multi employer processing
- HMRC recognised every year
Bear in mind: it is moving to cloud only for 2026/27, so long standing desktop users must migrate.

2. Sage Payroll
Sage Payroll makes a small pay run genuinely quick, and its anomaly detection catches the mistyped figure before payday rather than after. Auto enrolment assessment runs without you remembering, which for a small employer without a payroll specialist is exactly the safety net you want.
What you get: Sage's cloud payroll for start ups and small businesses. Three tiers, five employees included on each, with pension auto enrolment and HMRC notices built in. It holds a 4.0 out of 5 rating across 321 reviews on Assaylist.
Pricing: The plans run Payroll Essentials at £12, Payroll Standard at £23 and Payroll Premium at £34 per month, excluding VAT.
Why we rate it:
- Pension auto enrolment built in
- Payroll anomaly detection
- Automated HMRC notices
- HR features at every tier
Bear in mind: the five employee inclusion means the real cost is higher than the headline for a bigger team.

3. Xero Payroll
If you already run Xero, its payroll posts straight to the ledger with no journal to key, which removes an entire monthly reconciliation. Auto enrolment is handled properly with direct pension provider connections, and employees self serve their payslips. For an existing Xero user, running anything else means two systems.
What you get: Xero's UK payroll, included with the Grow plan and above and priced per person on Ignite. Auto enrolment, RTI and employee self service in the same system as the ledger. It holds a 4.0 out of 5 rating across 425 reviews on Assaylist.
Pricing: The plans run On the Ignite plan at £1.5, Included with Grow at free, Included with Comprehensive at free and Included with Ultimate at free per user per month, excluding VAT.
Why we rate it:
- Posts the payroll journal automatically
- Auto enrolment assessment built in
- Employee self service app
- Shares one audit trail with the ledger
Bear in mind: it is built for straightforward payrolls and a bureau will find it light.

IRIS Staffology prices by payslip volume rather than by employee, which genuinely helps a business whose headcount swings with the seasons or that runs several small payrolls. It is backed by one of the largest UK payroll groups and has a strong API for embedding payroll into a wider system.
What you get: The cloud payroll engine from IRIS, one of the largest UK payroll and accountancy software groups. Priced on the number of payslips you process, which suits variable headcounts. It holds a 4.0 out of 5 rating across 390 reviews on Assaylist.
Pricing: The plans run From 1 to 19 payslips at £43 and 20 to 50 payslips at a quoted price per month, excluding VAT.
Why we rate it:
- Priced by payslip volume, not headcount
- Strong API for embedding payroll
- Backed by a major UK payroll group
- HMRC recognised
Bear in mind: IRIS moved the detailed pricing behind a demo form, so a firm quote now takes a conversation.

5. QuickBooks Payroll
For an existing QuickBooks Online user, its payroll add on keeps everything in one ledger and posts the journal automatically. It handles RTI and auto enrolment cleanly and suits a business owner running payroll rather than a trained specialist.
What you get: Payroll for QuickBooks users, sold as a paid add on to any QuickBooks Online plan, with RTI submissions and pension auto enrolment. It holds a 4.0 out of 5 rating across 428 reviews on Assaylist.
Pricing: The plans run QuickBooks Payroll at a quoted price per month, excluding VAT.
Why we rate it:
- Posts the payroll journal automatically
- Auto enrolment assessment built in
- One supplier for accounts and payroll
- Employee self service portal
Bear in mind: it is a paid add on, so add its cost before comparing QuickBooks against bundled rivals.

Employment Hero is unusual in offering a genuinely free payroll tier, which lets a small employer run compliant RTI payroll at no software cost and pay only when they want more. It bundles HR and benefits alongside, so it suits a growing company that wants one platform rather than three subscriptions.
What you get: An Australian built platform that has grown fast in the UK, bundling HR, payroll and employee benefits. Notable for a free payroll option and per employee pricing. It holds a 4.1 out of 5 rating across 228 reviews on Assaylist.
Pricing: The plans run Free Payroll at free, Core Payroll at £3, HR Essentials at £4 and HR Engage at £7 per user per month, excluding VAT.
Why we rate it:
- Genuinely free payroll tier
- HR, payroll and benefits in one
- Well built employee app
- Per employee pricing that starts low
Bear in mind: the all in one breadth means it is good at many things rather than best at any one.

How much should you budget?
Cloud payroll for a small UK employer generally costs between twelve and thirty five pounds a month excluding VAT, often with a handful of employees included and a small charge, commonly around one to two pounds, for each additional person. Bureau grade desktop tools such as Sage 50 Payroll are priced in headcount bands that rise as you add staff, and fully managed services are quoted to your requirements.
The trap is the included headcount. A headline price that includes five employees can look cheap until you are paying for twenty, so work out your real per person cost at your actual and expected size. Also weigh whether payroll should live inside your accounting software, because the automatic journal posting that brings can be worth more than a small difference in the subscription.
Our verdict
If payroll is your profession, BrightPay is the specialist's pick, with IRIS Staffology the strongest option for variable or embedded payroll. For a small business running its own pay run, Sage Payroll is the most forgiving standalone tool, and its anomaly checking is a real safety net.
The best advice for most businesses, though, is to check what you already own. If you run Xero or QuickBooks, their payroll is the obvious first look because it shares your ledger, and Sage Accounting now bundles payroll entirely. Employment Hero's free tier is worth knowing about for the smallest employers. Match the tool to who will run it, and the choice becomes clear.
The bottom line
Match the tool to who will run it. If payroll is a profession in your business, BrightPay or IRIS Staffology give you the depth a specialist needs. If it is a monthly job for a busy owner, Sage Payroll is the most forgiving, and the payroll built into Xero, QuickBooks or Sage Accounting is the obvious first look if you already run one of those. Whatever you pick, make sure the real cost at your actual headcount, not the headline including a few employees, is the figure you compare.
Frequently asked questions
What is the best payroll software in the UK?
For payroll bureaus and accountants, BrightPay is the long standing favourite. For a small business running its own payroll, Sage Payroll is the most forgiving, while existing Xero and QuickBooks users should use the payroll built into those products. All handle RTI and auto enrolment to HMRC standards.
Is there free payroll software in the UK?
Yes. Employment Hero offers a genuinely free payroll tier that runs compliant RTI payroll at no software cost. HMRC also provides basic PAYE tools for very small employers, though dedicated software is far easier for auto enrolment and payslips.
Does UK payroll software handle pension auto enrolment?
Every product on this list handles pension auto enrolment, including the periodic assessment of staff and direct connections to the major workplace pension providers such as NEST and The People's Pension. This is one of the main reasons to use dedicated software rather than a spreadsheet.
How much does payroll software cost in the UK?
Cloud payroll for a small business typically starts around twelve to thirty pounds a month excluding VAT, often with a number of employees included and a small per employee charge above that. Bureau grade tools such as Sage 50 Payroll are priced in headcount bands, and managed services are quoted individually.
What is RTI in payroll?
Real Time Information, or RTI, is the requirement to report payroll details to HMRC on or before each payday rather than annually. All modern UK payroll software submits RTI automatically as part of the pay run, which is a legal requirement for almost all employers.
