The average cost of outsourcing payroll in the UK

On average, payroll outsourcing in the UK costs around £4 to £12 per employee each month, depending on the provider and the level of service included. However, if you're a small business with fewer than five employees, many providers charge a fixed monthly fee instead, often in the region of £25 to £60.^1,2,3

Generally, costs have risen due to the UK payroll landscape evolving - firstly with the Employment Rights Act 2025 and more recently, the new HMRC digital reporting rules which requires more work to be done to remain compliant.^4,5

Breakdown of Service Levels

What you'll pay largely depends on how much support you need. Most UK payroll providers and accountancy firms group their services into broad tiers such as basic processing, part-managed support, and more fully managed payroll and HR support.

Apart from the monthly subscription, you should budget for several common incidental costs. These may include:

• Set-up Fees: One-time onboarding costs for data transfer, payroll configuration, and PAYE setup are commonly charged separately.^9,3
• Year-End Filing: P60 and P11D-related work is sometimes billed as a separate year-end service if it is not included in the package.^6,11,3
• CIS (Construction Industry Scheme): Additional CIS processing is commonly priced separately because of the extra verification, deductions, and reporting requirements involved.^13,9,3

One cost people often overlook is the time and fees involved in paying staff. Some payroll and payment platforms charge per payroll payment or apply separate fees once you exceed included payment allowances, which can add to overall costs.¹²

💡 Wise Business gives you the ability to make batch payments where you can pay up to 1,000 employees or contractors in one go.

All you have to do is upload a spreadsheet (CSV), and should funds need to be converted during payment, they're done so at the mid-market exchange rate, with low, transparent fees.

How payroll outsourcing costs are calculated

UK payroll providers typically use three main pricing structures.^1,9,10

1. The per-employee-per-month (PEPM) model

This model charges a fixed fee per employee per pay cycle, and it aligns with the way payroll software and providers commonly price their services while handling HMRC RTI reporting obligations.^10,7

It’s one of the most common pricing structures, as it scales directly with your team size—making it predictable and easy to budget for as your business grows.^1,9,10

2. The frequency-based charge

This pricing model varies depending on how often payroll is processed, such as weekly, bi-weekly, or monthly runs.^1,9,3

More frequent payroll cycles typically involve more administrative work, data processing, and compliance checks, which can increase overall costs—especially for businesses with fluctuating staff hours or variable pay.^1,9,3

3. Complexity supplements

This model applies additional charges based on the complexity of your payroll setup, such as managing multiple pay types, bonuses, benefits, or industry-specific requirements like CIS.^13,1,9,3

Businesses with more complex payroll needs may face higher fees due to the extra time and expertise required, but simplifying pay structures and processes can help keep these costs under control.^1,9,3

Costs for part-managed and bureau payroll services

Bureau payroll services

A payroll bureau typically processes payroll using the employee and pay data you provide. In practice, pricing often combines a monthly minimum or base fee with a per-employee or per-payslip charge.^1,2,3

Part-managed services

A co-sourced model where providers handle more complex compliance tasks like auto-enrolment while your team retains control of day-to-day payroll inputs.^8,9 The average cost for this is typically lower than fully managed payroll on a per-employee basis, but internal admin costs still need to be considered.^1,9

Additional fees and hidden costs to watch out for

Statutory and year-end surcharges

Some providers charge extra for P60s and P11Ds, especially where year-end processing sits outside the standard monthly fee.^6,11,3 Statutory payments and related admin can also increase the time and cost involved in processing payroll.^6,7

Onboarding and exit fees

Initial setup fees are common, and some providers may charge for transferring or rebuilding your payroll data if you switch services.^9,3

Administrative add-ons

Additional costs may include pension communications, employee self-service features, HR integrations, and bank or payroll payment file submissions.^9,12,10

Factors That Influence Your Total Payroll Costs

• Pay Frequency: More frequent payroll runs can increase costs.^1,9,3
• Workforce Complexity: Mixed pay structures, variable hours, and benefits administration may raise pricing tiers.^13,1,9,3
• Statutory Requirements: Additional compliance tasks can add fees.^8,6,11,7
• Industry-Specific Schemes: For example, CIS requirements can increase admin and reporting work.¹³

Outsourcing vs in-house payroll: cost comparison

Using software like Xero or Sage can have lower direct subscription costs, with entry-level UK pricing currently starting from about £16 per month for Xero’s Ignite plan and £5 per month for Sage Payroll before employee-based charges or payment fees are added.^14,12,10 However, this doesn’t include the time required to run payroll, stay compliant with HMRC rules, and manage tasks like pensions, submissions, and year-end reporting.

In comparison, outsourcing payroll can cost £4 to £12 per employee or more per month^1,2,3. Some providers might charge a fixed fee of roughly £25 to £60 for very small teams as well. While this is more expensive upfront, it usually includes payroll processing support, RTI submissions, and help with regulatory obligations.
