Best Payroll Software

Ten platforms made our shortlist. All ten are HMRC-recognised, so you can run RTI without worrying about basic compliance.

All ten submit RTI. All ten handle auto-enrolment.

So the comparison you actually need is not about compliance checkboxes: it is about what breaks when your headcount changes, what happens at renewal, how long implementation takes, and whether the pricing model suits your pay frequency and employee mix.

The UK payroll software market has two structural problems. First, headline pricing rarely survives contact with an actual quote.

• Sage
• Moorepay
• ADP
• and Cintra all have bespoke or opaque pricing
• what you see on the website either requires a demo call or understates the ongoing cost by promoting an introductory rate

Second, several products have undergone structural changes since 2023: BrightPay is retiring its desktop product, Xero restructured its plan tiers in September 2024, and Cintra was acquired by IRIS.

This review reflects the current state of each platform in April 2026, not what was true two years ago, so your shortlist is based on what you can actually buy today.

No single platform wins all scenarios. The picks below are organised by real buyer situations. Read the shortlist first, then go to the provider section for the detail that will actually change your decision.

Which UK Payroll Software Made Our Shortlist?

The six picks above cover most UK buyer scenarios. For the majority of businesses under 50 employees running straightforward monthly payroll, BrightPay or Employment Hero will be the right answer at a fraction of the cost of mid-market alternatives.

The category exceptions below exist because price is not the only variable.

Best Overall UK Payroll Software

BrightPay wins on price-to-compliance ratio. At £209/year for up to 25 employees (2025/26 desktop pricing), no HMRC-recognised alternative comes close.

The cloud pricing from 2026/27 uses a calculator model rather than a published tier table, which introduces some uncertainty, but early indications from beta users suggest the cost remains below Sage or Xero for the same headcount.

The caveat is the cloud migration. Desktop BrightPay has no compliance updates after April 2026. Buyers who have not migrated by then are running non-compliant payroll.

For businesses that have already migrated or are starting fresh on the cloud product, this is not a live concern. For desktop holdouts, it is the most urgent payroll decision of 2026.

Named limitation: BrightPay does not produce P11D forms natively. UK employers running benefits-in-kind (company cars, private medical, salary sacrifice outside payrolling) must use HMRC’s P11D Online service or a third-party module.

The cloud billing model also charges on the highest recorded headcount in the period rather than average, so a single month of seasonal staff lifts the annual band.

Best UK Payroll Software for Small Businesses (Under 10 Employees)

Employment Hero Payroll at £0/month with no employee cap is the hardest argument to beat for a small business running straightforward payroll. The free tier includes RTI, auto-enrolment, SSP/SMP, P60s, employee self-service, and accounting integrations with Xero, QuickBooks, and Sage.

There is no trial period and no forced upgrade to a paid plan, so your cost stays at zero unless you choose to add HR features.

The trade-off: Employment Hero is built around HR adoption. The free payroll is the entry point into a broader platform.

Businesses that genuinely need only payroll will find features they will never use and a UI organised around HR workflows rather than payroll-first thinking.

Named limitation: Employment Hero’s UK auto-enrolment workflow leans on its PensionSync integration rather than direct submissions to every scheme; employers on niche or trust-based schemes outside PensionSync’s connector list still upload contribution files manually.

CIS handling is also weaker than BrightPay or IRIS, and the platform’s Australian engineering heritage occasionally surfaces in UK statutory edge cases such as complex SMP recovery and director NI alternative methods.

Best UK Payroll Software for Growing Teams

Pento serves the 50-300 employee bracket where Xero’s cap becomes a migration risk and Sage 50 Payroll feels dated.

Pento’s real-time payroll model means mid-month changes update immediately rather than batching to end-of-month.

Pricing is quote-only, typically £4-6/employee/month plus an implementation fee. Not suitable for businesses under 30 employees.

Named limitation: Pento’s UK compliance track record is shorter than incumbents (UK operation since 2020), and the implementation fee of £1,500-3,500 is a real upfront commitment that materially distorts the year-one cost comparison against Xero or BrightPay.

Per-employee pricing also crosses BrightPay cloud’s annual cost at roughly 40 employees, so businesses sitting just over Xero’s cap should price both before committing.

Best Value UK Payroll Software

BrightPay wins on per-employee cost for paid software. Employment Hero Payroll wins on zero upfront cost for unlimited employees.

Sage’s “90% off for 6 months” promotional rate understates the ongoing cost; Standard runs £20/month for 5 employees once the offer expires.

How Do UK Payroll Software Prices and Features Compare Side by Side?

The table below reflects verified pricing as of April 2026. Quote-based products show reported ranges from G2, Capterra, and published comparisons. All providers listed are HMRC-recognised for RTI.

Sources: xero.com/uk/pricing-plans/, brightpay.co.uk/pricing/, employmenthero.com/uk/pricing/, gov.uk HMRC RTI recognised software list. Quote-based pricing from G2/Capterra reviewer self-reports and published comparison sources, April 2026.

The cost differential between the cheapest and most expensive options on this list is significant. At 50 employees, Payfit Premium runs approximately £469/month (£5,628/year).

BrightPay cloud handles the same headcount at a fraction of that cost. The premium platforms are not overpriced if HR functionality, real-time data, or managed processing is part of the purchase.

The comparison is only valid if you are buying the same thing.

Where Does Each UK Payroll Platform Genuinely Win or Lose?

Every platform below handles the HMRC basics:

• RTI
• auto-enrolment
• PAYE
• National Insurance
• statutory pay

The comparisons that matter are pricing model, scaling behaviour, integration dependencies, and the things the marketing copy does not emphasise.

Xero Payroll

Xero Payroll works well inside the Xero accounting ecosystem and nowhere else. If you already run Xero for bookkeeping, the payroll addition is genuinely low-friction: payroll journals post automatically, RTI submissions happen in the same interface, and the learning curve is minimal.

There is no argument for choosing a separate payroll tool if you are already paying for Xero Grow or above.

Pricing: Grow plan £37/month (includes 1 payroll employee, £1.50/additional); broad £50/month (5 employees included); Ultimate £65/month (10 included).

Payroll is not available on the Ignite plan following the September 2024 restructure.

What works: Accounting integration, clean UI, reliable RTI submissions, pension direct submissions to NEST and The People’s Pension.

What does not: Hard 200-employee cap with no migration path within Xero. No native P11D production; employers with benefits-in-kind need HMRC’s own P11D Online or a third-party module.

Pension direct submissions only for NEST and The People’s Pension; all other providers require a manual file upload. Multi-currency payroll is not supported.

Xero Payroll is the right answer for businesses under 150 employees already on Xero accounting.

It is the wrong answer if you are approaching 200 employees, run a benefits-in-kind scheme, or are not already using Xero.

Sage Payroll

Sage operates two distinct UK payroll products: Sage Business Cloud Payroll (cloud-native, three tiers) and Sage 50 Payroll (desktop-first, annual licence, tiered by employee count from 15 employees). These are different products with different pricing, support, and feature sets.

Many buyers arrive expecting one and discover the other.

Pricing: Sage Business Cloud Payroll: Essentials £10/month, Standard £20/month, Premium £30/month (each per 5-employee base, ex-VAT). The first 6 months are 90% discounted as of April 2026, which materially understates the ongoing cost.

Sage 50 Payroll is priced on annual licence by employee tier.

What works: Deep HMRC integration, decades of UK compliance history, P11D support in Sage 50 Payroll, large UK support team, accountant network integration.

What does not: Sage Business Cloud Payroll does not produce P11D forms natively; employers with benefits-in-kind must use HMRC’s own service or a separate module.

Renewal pricing behaviour documented in user reviews is a real risk: one verified review documented a 64.3% price increase at annual renewal with no advance notice.

Trustpilot scores for Sage company-wide hover around 2.2/5, predominantly billing and support complaints.

The RTI submission flow has a known friction point: FPS is submitted before a P45 can be printed, catching payroll admins new to the platform.

Sage is a safe choice for mid-market UK employers who value incumbent-brand compliance reliability and have an accountant already working in Sage.

It is not a value play at SMB scale and requires active pricing management at renewal.

BrightPay

BrightPay has been the price leader in UK SMB payroll for over a decade and remains so in 2026, even accounting for the cloud transition.

The compliance depth is genuine: direct auto-enrolment submissions to NEST, The People’s Pension, and Smart Pension; reliable RTI; CIS support; a 89% Capterra recommendation rate from over 700 verified reviews.

For accountancy practices running multiple clients, the bureau licence is unmatched value; Sage and Xero charge per-client or per-seat.

Pricing: 2025/26 desktop: £79/year (3 employees), £139/year (10), £209/year (25), £289/year (unlimited). From 2026/27, cloud pricing only via interactive calculator at brightpay.co.uk/pricing/.

The cloud billing model charges based on the highest recorded employee count in the period, not average. A single month of temporary staff can lift the annual billing tier.

What works: Lowest cost per employee on this list, reliable HMRC compliance, bureau licence, CIS support, strong pension integrations, clear desktop-to-cloud migration path.

What does not: Cloud pricing model is opaque at the point of research. No native HR suite.

Setup mid-year can be difficult according to user reviews. Data residency: Bright is Irish-owned, Azure-hosted; some UK procurement teams flag this in DPA assessments.

Desktop product has no compliance updates after April 2026.

BrightPay is the default choice for UK SMBs that need pure payroll at minimum cost. The cloud migration is not optional and must be completed before April 2026 for continued compliance.

Employment Hero Payroll

Employment Hero Payroll’s free tier is real: unlimited employees, full RTI, auto-enrolment assessment, SSP/SMP, P60s, P11D submissions, employee self-service, and accounting integrations. No trial period. No forced upgrade.

It is the only major UK payroll platform that makes this offer.

Pricing: Free tier: £0/month, unlimited employees. Managed Payroll: £12/employee/month. HR plans from £4/employee/month with payroll as an add-on.

What works:

• Free tier feature depth
• PensionSync integration (direct submission to multiple pension providers)
• P11D included
• employee app (Employment Hero Work)
• Australian-origin compliance build adapted for UK

What does not: Pure payroll buyers are navigating an HR platform. Support for ongoing queries draws mixed reviews: praised at onboarding, criticised for resolution speed after go-live.

UK-specific nuances, particularly complex CIS or benefits-in-kind scenarios, may lag providers built natively for the UK market.

The KeyPay API naming still appears in some integrations, which can confuse new buyers researching the platform.

For a small business running basic UK payroll, Employment Hero is the lowest-cost credible option.

For a 100-person business with a complex pay structure or significant benefits-in-kind, the HR-first architecture starts to create friction.

ADP (UK)

ADP suits UK multinationals and mid-to-large enterprises needing multi-country payroll and a deeply managed service.

For under-50-employee businesses it is almost always the wrong choice, and the procurement process confirms that orientation.

Pricing: Quote-only. G2 and Capterra reviewer self-reports cluster at £4-10/employee/month for iHCM base payroll; implementation fees commonly run into five figures for mid-market deployments.

What works: Full P11D support, multi-country payroll via ADP Celergo, NelsonHall Leaders Quadrant placement for managed payroll.

What does not: Implementation runs 8-16 weeks vs 1-4 weeks for cloud-native rivals. The product line (iHCM, Celergo, Freedom, Workforce Now) confuses buyers arriving via generic search. Interface is functional but visually dated relative to modern cloud tools.

Support quality drops sharply below the 500-employee threshold.

ADP belongs in a shortlist for 250+ employee businesses with multi-country obligations. It does not belong in an SMB comparison.

IRIS Payroll

IRIS Payroll is four distinct products:

• Staffology (modern cloud
• API-first)
• IRIS PayrollPro (bureau hybrid)
• KashFlow Payroll (small-business cloud)
• and legacy desktop for accountants

Buyers must identify which product they are evaluating before any comparison is meaningful.

Pricing: No published pricing for Staffology or PayrollPro. KashFlow starts around £5/month. Flagship quotes require a sales call, typically 5-10 business days.

• What works: 30+ years of HMRC-recognised engineering
• P11D and CIS across most products
• Staffology&#8217
• s full REST API with webhooks (rare in UK payroll)
• deep bureau capabilities

What does not: Product fragmentation is a genuine buyer problem. Procurement delay is structural, not incidental. Post-Cintra-acquisition, IRIS owns overlapping products not yet fully rationalised.

For accountancy practices and payroll bureaus, IRIS has genuine depth. For SMBs wanting fast self-service implementation, the procurement journey alone will push them toward BrightPay or Xero.

Pento

Pento’s key differentiator: payroll data updates in real time, not at a monthly cut-off. New hires, leavers, salary changes, and bonuses update immediately.

For simple monthly payroll this is irrelevant. For businesses with variable headcount or complex bonus cycles, it removes a class of reconciliation errors batch-processing systems accumulate.

Pricing: Quote-only. Independent sources report £4-6/employee/month plus a one-off implementation fee of £1,500-3,500 for the 50-250 employee bracket (PeoplePro 2025, SoftwarePundit 2025).

What works: Real-time architecture, strong API integrations, HMRC-recognised RTI, cloud-native from inception.

What does not: Expensive for under 30 employees. Implementation fee is a real upfront commitment. Payroll-only, no HR suite.

Shorter UK compliance track record than Sage or BrightPay (UK operation since 2020).

For businesses approaching Xero’s 200-employee cap or still running Sage 50 on a desktop, Pento is worth pricing seriously.

Moorepay

Moorepay occupies the managed-service middle ground: more capable than SMB self-service tools, less complex than ADP. CIPP Payroll Assurance Scheme re-accredited 2025, ISO 27001, CIPP Payroll Service Provider of the Year 2023.

Part of Zellis Group.

Pricing: No published pricing. Self-service software approximately £50/month for 10 employees, scaling to £200+/month for 100+. Managed payroll approximately £5-8/employee/month.

Annual contracts standard; early exit charges equivalent to 12 months’ fees reported on Trustpilot.

What works:

• Managed payroll depth
• dedicated payroll specialist
• Natural HR integration (acquired March 2023)
• employment law helpline add-on
• CIPP-qualified team

What does not: Every comparison requires a demo call. The 12-month exit charge makes a wrong purchase expensive. Some users report performance issues at peak processing periods.

Moorepay suits 50-500 employee businesses willing to commit to a managed relationship. Buyers needing published pricing for procurement approval should look elsewhere.

Payfit

Payfit is a combined payroll and HR platform, not a pure payroll tool. The question it forces is whether the HR functionality justifies the premium over a dedicated payroll tool.

For a 30-person business with no HRIS spending £50-100/month on a separate HR tool, the consolidation case is real. For a business that already has an HRIS and needs only payroll, the pricing is hard to justify.

Pricing: Light: £29 base + £5/employee/month. Standard: £59 base + £6/employee/month. Premium: £119 base + £7/employee/month.

At 50 employees on Premium: approximately £469/month (£5,628/year). BrightPay handles the same headcount for under £200/year. The cost differential is only rational if HR features are in active use.

What works: Payroll and HR in one platform, automated RTI, auto-enrolment assessment, leave management, document e-signatures, employee onboarding. Clean UI praised in user reviews.

P11D handling confirmed for automated submissions.

What does not: Pricing stacks quickly at higher employee counts. The HR features are not the deepest in the market for dedicated HRIS buyers. Some gaps in complex UK compliance scenarios (CIS, complex benefit structures) noted in user reviews.

Not designed for the accountant/bureau market.

Payfit is the right platform for a 20-80 employee business that wants to collapse payroll and basic HR admin into one tool without enterprise-level complexity.

It is the wrong choice for businesses that already have a functioning HRIS.

Cintra Payroll

Cintra’s differentiators: named payroll manager (not a shared ticket queue), multi-entity and multi-currency support in iQ, and CIPP PAS plus ISAE 3402 Type II assurance, a combination almost no smaller UK provider holds.

Pricing: Quote-only. Post-IRIS acquisition, features previously bundled are now charged as separate modules per 2024-2025 Capterra reviews. Rebuild your cost comparison from scratch at renewal.

What works: Named payroll manager model, multi-entity and multi-frequency processing, strong audit trail, compliance depth for group structures.

What does not: Cintra was acquired by IRIS in May 2023 and now competes directly with IRIS’s own Staffology and KashFlow lines. The roadmap question is not resolved publicly.

The named-manager model should be confirmed in the SLA, not assumed.

Cintra suits 100-500 employee organisations needing multi-entity payroll and third-party audit assurance. Raise the IRIS roadmap question before signing.

How Did We Evaluate the Best UK Payroll Software?

We evaluated each platform across five dimensions, weighted by buyer situation rather than applied equally.

1. HMRC compliance depth. RTI recognition is a baseline. We differentiated on P11D handling, CIS support, pension submission breadth (direct electronic vs manual file), and statutory payment automation.

Depth matters if your payroll has complexity beyond basic monthly PAYE.

2. Pricing model honesty. Headline price is rarely the whole story.

We assessed whether prices are published or quote-only, whether promotional rates mask ongoing cost, how billing scales with headcount, and whether renewal pricing patterns diverge from entry pricing.

BrightPay’s highest-recorded-count billing model and Sage’s documented renewal uplift are both relevant buying signals.

3. Scaling behaviour. We noted hard employee caps (Xero at 200), practical sweet spots by platform design, and at what point a business should plan to migrate.

A platform right for 20 employees can be wrong at 80; that migration cost belongs in the purchase decision.

4. Integration dependencies. Whether payroll runs well standalone or requires another product to justify its cost (Xero Payroll needs Xero Accounting; Employment Hero’s payroll is a gateway to its HR platform).

We assessed accounting journal automation, pension integrations, and HR system connections.

5. Limitations transparency. We used user review signals from G2, Capterra, and Trustpilot to surface operational friction not visible in vendor marketing.

Consistent complaint patterns are treated as structural limitations, not isolated incidents.
