A payroll bureau handles one of the most compliance-critical functions in any UK business — getting employees paid correctly and on time while staying compliant with HMRC's increasingly complex RTI requirements. For the estimated 40% of UK small businesses that outsource payroll, a bureau service removes the monthly compliance burden while typically costing less than the internal staff time required to run payroll manually.

Our Verdict

The most cost-effective UK payroll bureau for most small businesses (1–25 employees) is your accountant — they already know your business, charge competitive per-payslip rates (£2–6/payslip), and handle RTI as part of their existing HMRC relationship. For dedicated bureau services: IRIS Payroll Bureau and PayFit consistently receive the strongest reviews. Always check CIPP Payroll Assurance Scheme certification as a quality mark.

What a UK Payroll Bureau Provides

Payroll calculations — gross-to-net for all employees including PAYE, NIC, student loan deductions
HMRC RTI submissions — Full Payment Submissions (FPS) and Employer Payment Summaries (EPS) on or before payday
Payslip production — digital or paper payslips to employees each pay period
Auto-enrolment management — assessing eligibility, enrolling workers, calculating contributions, submitting to pension provider
Statutory payment calculations — SSP, SMP, SPP, ShPP, PILON
P60 year-end reporting — issued to all employees by 31 May
P11D reporting — often an additional charge
CIS management — specialist service for construction firms with subcontractors

💡 The cheapest payroll bureau is almost always your accountant: Most UK accountants offer bureau payroll. For a business with 10 employees paying monthly, your accountant might charge £3–5 per payslip = £30–50/month including RTI, pension management, and year-end P60s. Compare this against dedicated bureau services before switching.

Frequently Asked Questions

What is a payroll bureau?

A payroll bureau is a specialist company or accountancy practice that processes payroll on behalf of multiple client businesses. The bureau runs your pay calculations, submits RTI to HMRC, manages auto-enrolment pensions, generates payslips, and handles year-end P60 reporting. You remain the employer and submit employee data changes; the bureau handles the rest.

How much does a payroll bureau cost UK?

UK payroll bureau services cost approximately £2–15 per employee per month depending on the service level and provider. Part-managed payroll (processing only): £2–3/employee/month. Fully managed bureau: £4–10/employee/month. Many accountants offer bureau payroll at £2–6 per payslip. A business with 10 employees can expect to pay £25–100/month.

Is a payroll bureau regulated in the UK?

There is no specific licence required to operate a payroll bureau in the UK. However, reputable bureaux are HMRC-recognised for RTI filing, and many hold the CIPP Payroll Assurance Scheme (PAS) certification — a quality standard introduced by HMRC and the Chartered Institute of Payroll Professionals. Look for CIPP PAS certification as a quality indicator when choosing a bureau.

Can my accountant act as my payroll bureau?

Yes — the majority of UK accountants offer payroll bureau services to their business clients. They process payroll using HMRC-recognised software (BrightPay, Sage, IRIS, TaxCalc), submit RTI, and manage pensions. For businesses with 1–25 employees, your accountant's bureau rate is often the cheapest and most convenient option — they already know your business.

What is the difference between a payroll bureau and payroll outsourcing?

A payroll bureau processes your payroll data and submits it to HMRC on your behalf — a specific service. Payroll outsourcing is a broader term that can include the bureau service plus additional services like HR advisory, compliance management, and strategic payroll advice. In practice, the terms are used interchangeably for most SME purposes.
