Payroll outsourcing in the UK typically costs £4–£10 per employee per month for fully managed services, plus a small one-off setup fee. For a practice with 1–10 employees on a client’s payroll, expect roughly £4–£6 per employee per month; costs fall as employee numbers rise. Pension auto-enrolment and HR integration are usually priced as add-ons.
Key Takeaways
- Fully managed payroll outsourcing: £4–£10 per employee, per month, in the UK.
- Part-managed (hybrid) payroll costs less but keeps day-to-day control in-house.
- A one-off setup fee applies to most providers, usually a nominal amount.
- Pension auto-enrolment and HR integration are typically charged separately.
- Outsourcing to a provider fell 22% among UK payroll teams in 2025, while outsourcing to an accountant rose 18%, per Moorepay’s 2025–26 survey — accountants are increasingly the outsourcing route of choice.
What is Included in Payroll Costs?
Payroll outsourcing cost covers more than a per-payslip fee — it includes statutory compliance, software, and administration time, not just processing.
While accounting practices handle payroll tasks for their clients, rising employee numbers quickly increase workload and operational pressure. Add the complexity of ever-changing payroll regulations, and in-house delivery becomes both costly and risky—making payroll outsourcing a practical, cost-efficient solution for growing practices.
How to Outsource Payroll
When your clients expand their business more employees will be recruited which is good news for you but there is a catch. You are already handling the payroll for your clients and additional work will only burden your in-house team and reduce their efficiency. Hence, it becomes a necessity to outsource payroll to a service provider. By outsourcing to a third-party payroll service provider, you are handing over extra work to them which has a positive impact on your services.
Types of Outsourced Payroll?
Taking care of payroll in-house will naturally be a burden on your pocket therefore to reduce your burden you must choose to outsource payroll. But for that, you have to research what type of payroll service will meet your requirements. Yes, you read it right: there are types of payroll services, fully managed and part-managed payroll services.
Fully Managed Payroll Service: Under this type, you are completely handing over your payroll responsibilities to a payroll service provider. The service provider will handle all dealings with HMRC and respond to your clients’ queries.
Part-Managed Payroll Services: Here you will get the option of outsourcing certain payroll responsibilities while retaining the rest. Under this type, experienced payroll specialists handle the most complex payroll tasks, which you outsource.

How do payroll outsourcing fees vary between providers?
Payroll outsourcing fees vary between providers based on the scope of services offered, payroll volume, and level of compliance support required. Providers offering fully managed payroll typically charge more than part-managed services, as they handle end-to-end processing, HMRC submissions, and employee queries.
Costs also differ depending on pay frequency, number of employees, and the payroll software used, especially when advanced systems or integrations are involved. Additional services such as pension auto-enrolment, year-end filings, CIS processing, and HR integration can further influence overall costs.
For accounting practices, choosing the right provider is less about the lowest fee and more about value, accuracy, scalability, and compliance assurance.
What is The Cost of a Payroll Service That is Fully Managed?
On the one hand, with part-managed payroll services, the cost will be less because you are not opting for a full handover. You are only outsourcing certain payroll services while remaining in complete control of the day-to-day processes, such as maintaining employee records and updating wage information. However, your payroll service provider will take care of the tricker parts, such as filing year-end reports and making payroll complaints regarding HMRC regulations.
On the other hand, under a fully managed payroll service, you hand over complete control of your payroll service to a third-party service provider. The cost of a fully managed payroll will depend on the frequency with which your clients pay their staff. Furthermore, this type of payroll service divides into four parts, each incurring a separate cost. Let’s understand each of them.
- Payroll Service: If you select to outsource through a fully managed payroll service, it will cost you approximately £4 to £6 per employee per month, but only if your clients employ 1 to 10 people. The larger your client’s workforce, the lower the individual cost.
- Setup Cost: This cost will undoubtedly apply, but it will be a nominal cost.
- Pension Plan Auto-Enrolment: When you auto-enrol your client’s staff into pension plans, the cost should not exceed a certain amount. Also, make sure to ask questions about the auto-enrolment price because there are tendencies to overcharge.
- HR Integration: If you want to integrate HR and payroll management, then you will have to pay more.
The Advantages and Disadvantages of Completely Managed Payroll Services
Gone are the days when payroll means just dealing with payslips. Nowadays, you will have to deal with a host of payroll-related issues, such as dealing with HMRC regarding the submission of necessary details to make PAYE payments on time. All this has increased your payroll staff’s workload, so you would love to outsource payroll services to a service provider. But is it worth it? To answer that, you will need to understand its advantages and disadvantages.
Advantages
Focus on Accuracy
Third-party payroll service providers always make it a priority to recruit experienced payroll specialist to do the job. This way they are ensure accuracy in the payroll process especially when huge numbers are involved.
Reduces Time Wastage
Even for accounting practices like yours, managing payroll in-house is becoming time-consuming. Nowadays, payroll processing involves keeping records of benefits, deductions, new hirings, and termination and frustratingly monitoring regulator changes. Of course, this consumes much time, which can be better utilised for other important purposes. To save time, you can choose to outsource payroll services to a third-party service provider.
Reduces Hassle
When your client expands its business, it has to increase its employee count, which has a direct effect on your workload regarding keeping track of deadlines and processing payroll. You don’t need to worry about it; the payroll services provider will take care of everything.
Resolves Queries
Employees can submit queries about deductions or salary calculations directly to the payroll services provider if they have any concerns.
Ready for Audits
With professional third-party payroll services providers handling your client’s payroll, they will be compliant with the National Minimum Wage mandated by the Low Pay Commission and HMRC regulations. So they would not have to worry about penalties or face negative publicity due to non-compliance.
Compliance Issues
Payroll regulations are subject to frequent changes that become difficult to track. Missing out on these changes will lead to non-compliance, which will be costly for you and your clients. Hence, handing over such a delicate task to a payroll services provider makes sense.
Use of Payroll Software
There are multiple payroll software programs in the market, such as Sage, Brightpay, Xero, Moneysoft, Earnie, and Star Payroll. These programs are expensive and require experience to handle. But payroll service providers are already using them, so just outsource and save your money.
Disadvantages
Loss of Control
Once you hand over all your payroll-related tasks to a payroll services provider, you lose control over the day-to-day processes. Hence, it is important to be aware of the type of payroll outsourcing you are choosing. If you’re interested in retaining control for yourself and your client, then choose a part-managed payroll service.
Realistic Deadlines
You cannot expect that you will suddenly give important information to your service provider, and they will implement it in the payroll at once. Also, in the haste of sending information, you may miss out on certain crucial information. So, you must give yourself some time to collect all the information and then send it.

While additional services may affect pricing, outsourcing payroll helps accounting practices control costs, reduce compliance risk, and avoid the overheads of staffing, software, and ongoing training.

People Also Ask
What are the pros and cons of fixed-fee vs time-based billing for outsourcing?
Fixed-fee billing gives predictable monthly costs and works well for routine, well-defined payroll runs, but carries a risk of hidden costs if scope creeps beyond what was agreed. Time-based billing suits complex or changing payroll needs and avoids undercharging, but costs become harder to forecast and there’s less incentive for the provider to work efficiently. Most UK accounting practices with steady client numbers prefer fixed-fee for cost certainty.
What should I consider when comparing payroll costs across different companies?
Don’t compare price alone — compare what’s included. Check the pricing model (per-employee vs. fixed monthly fee), what’s bundled versus billed as an extra, how the provider prices complex payrolls (CIS, multiple pay frequencies), and whether there are hidden fees for one-off tasks like P11D forms. Also weigh data security accreditations, scalability as client headcount grows, and overall service quality — the cheapest quote isn’t always the lowest total cost.
