How Much Do Payroll Services Cost In The UK: 2026 Guide

Managing a growing team brings exciting opportunities, but it also introduces complex administrative challenges. Calculating wages, tracking statutory leave, and ensuring HMRC compliance takes significant time and expertise.

If you are a small business owner or HR leader, you are likely asking a key question: should you keep payroll in house, or is it time to outsource?

If you are already considering external support, our payroll services provide fully managed, compliant payroll solutions tailored to your business.

This 2026 guide breaks down the true cost of payroll in the UK, including pricing models, hidden fees, and how legislation changes impact your payroll costs.

Quick Summary Of Payroll Costs

For most UK businesses, payroll outsourcing costs fall into two main models:

• Per employee per month (PEPM): £4 to £12 per employee
• Per payslip: £2 to £15 depending on service level

Small businesses often pay a minimum monthly fee between £30 and £100+, depending on complexity and service level.

Setup costs typically range from £30 to £150.

Pricing Models And Payroll Cost Drivers

Per Employee / Per Payslip Pricing

This is the most common pricing model. Costs scale as your team grows, making it predictable and easy to budget.

Fixed Monthly Pricing

Some providers offer fixed fee packages for smaller businesses. This removes uncertainty and helps avoid hidden costs.

Payroll Frequency Impact

Weekly payroll increases costs due to more frequent processing and RTI submissions. Monthly payroll is typically more cost-effective.

Number Of Employees

As your team grows, the cost per employee often reduces due to economies of scale.

The 4 Types Of Payroll Systems

3. Fully Managed Payroll Services

4. Part-Managed Payroll

What Payroll Processing Includes

A quality payroll service should include:

• Gross-to-net calculations
• Income tax and National Insurance deductions
• Statutory payments, including SSP, SMP and SPP
• RTI submissions, including FPS and EPS
• Pension auto enrolment
• Payslip generation

If these are charged as extras, you may be dealing with hidden fees.

Costs Of Keeping Payroll In House Vs Outsourcing

Many businesses assume in-house payroll is cheaper. In reality, it is often more expensive.

Hiring a payroll employee costs £30,000+ annually, plus:

• Employer National Insurance
• Pension contributions
• Training and compliance costs
• Software subscriptions

By comparison, outsourcing payroll for 50 employees at £6 per employee costs just £3,600 per year.

2026 Regulatory Impacts

From April 2026, statutory sick pay rules are changing:

• SSP will be payable from day one
• The lower earnings limit is being removed

This increases payroll complexity and makes accurate payroll processing more critical than ever.

National Living Wage Increases

Rising wages increase:

• Gross payroll costs
• Employer National Insurance
• Pension contributions

Understanding National Insurance contributions is essential for accurate cost planning.

Hidden Fees To Watch Out For

Always check for:

• Setup fees, usually £30 to £150
• Year-end charges, such as P60s and P11Ds
• Pension setup fees, often £100 to £250
• Integration costs
• Exit fees
