Your people are the backbone of your business. Getting their pay right, every time and on time, is one of the most important responsibilities you manage. Yet for growing businesses without a dedicated finance function, payroll services across the UK can quickly become one of the most time-consuming and compliance-heavy tasks you face. That is where Old Mill comes in.
Old Mill offers outsourced payroll services designed around the way your business works. Whether you are hiring your first employee or managing a growing workforce of full-time, part-time, and seasonal staff, our specialist payroll team supports you with every detail, so you can stay focused on what you do best.
From PAYE calculations and National Insurance contributions to statutory deductions, RTI submissions, and payslip production, we manage the full payroll cycle on your behalf. You simply share your data; we handle everything else with accuracy, care, and a focus on maintaining HMRC compliance.
We also support businesses through the often complex process of auto-enrolment, helping you meet your workplace pension obligations without adding pressure to your team. Whether you are setting up a pension scheme for the first time or managing ongoing contributions, our payroll specialists will guide you through every step.

You may be wondering, is outsourced payroll really worth it for a business of my size? The short answer is yes, and here is why.
Payroll legislation changes constantly. The National Minimum Wage, National Living Wage, auto-enrolment rules, and HMRC reporting requirements all evolve throughout the year. Keeping up while also running a business is genuinely difficult. Payroll support for SMEs means you have qualified experts who keep track of these changes, helping reduce the risk of anything being missed.
Beyond compliance, outsourcing removes a significant administrative burden from your plate. It reduces the risk of errors, protects employee confidence, and frees your time for decisions that grow your business. For many of our clients, the real benefit is peace of mind: knowing that payroll is being handled correctly, each payroll period, without them needing to think about it.
No two businesses operate in the same way, which is why our PAYE payroll services teams take the time to understand your specific setup before building your service. Here is what our payroll bureau services include:
| Service | What it covers |
| Managed payroll transition | Smooth handover from your current setup with no disruption to employees |
| HMRC-compliant processing | All submissions, deductions, and RTI returns handled correctly and on time |
| Employee portal | Payslips, P45s, P60s, and pension letters accessible anytime |
| Auto-enrolment support | Guidance through workplace pension legislation and administration |
| Net pay payment solution | No banking templates required; we handle the payment process |
| Dedicated team member | A named contact who knows your business |
Getting started is straightforward. We manage the transition from your existing payroll setup, whether that is an in-house spreadsheet system or a previous provider, ensuring your employees experience no disruption and your data is transferred securely and accurately.
One of the most valued aspects of our service is the personal touch. You are not passed between departments or left on hold. Our employee payroll management teams assign a dedicated payroll specialist to your account, someone who understands your workforce structure, your pay periods, and the specific compliance requirements for your industry.
This continuity matters. It means queries are resolved quickly, your employees receive consistent support, and you build a working relationship based on trust and shared knowledge. When something changes in your business, your payroll specialist is already up to speed and ready to adapt.
Payroll sits within a broader financial picture. For businesses looking to bring more clarity to their finances, our digital accounting services give you real-time visibility into your numbers. Powered by cloud accounting platforms including Xero, our advisers can set up, train, and support your team to get the most from your financial data.
Connecting your payroll with your wider accounting function creates a more complete view of your business, with fewer surprises at month-end.
For growing businesses without an in-house finance function, payroll is often just the starting point. Old Mill’s outsourced finance service brings you the equivalent of a dedicated finance team, without the cost and complexity of building a team in-house. From bookkeeping and management accounts to strategic financial guidance, we support ambitious SMEs across the South West and beyond.
Together, these services form a joined-up approach to financial management, one that grows with your business, not against it. Many of our clients begin with payroll and gradually bring more of their finance function across to us, building a partnership that supports their long-term goals.
