Running a small company in the UK is both exciting and challenging. As a business owner, you juggle multiple responsibilities—from growing sales to managing employees. One of the most critical tasks is payroll management. Ensuring staff are paid accurately and on time is not just about maintaining good relationships with employees—it’s also a legal obligation.
If you’re new to payroll, you might already have come across the term Payroll Service Number UK. Many small businesses get confused about what this is, why it matters, and how to get the right number or service for their company. This guide will break it all down step by step, so you can make informed decisions and keep your business compliant.
What is a Payroll Service Number UK?
The phrase Payroll Service Number UK is often used by small businesses searching for help with payroll. In reality, it usually refers to two key things:
- Employer PAYE Reference Number
- Issued by HMRC (HM Revenue and Customs) when you register as an employer.
- It identifies your business in the UK payroll system.
- You need this number to submit PAYE (Pay As You Earn) information, report taxes, and make National Insurance contributions.
- Payroll Service Provider Contact Numbers
- Many companies search for payroll service numbers when they want to get in touch with outsourced payroll providers or HMRC support.
- These services help small companies handle payroll tasks if they don’t have the time, tools, or expertise.
For most small companies, both meanings are relevant. You’ll need your official HMRC payroll number, but you may also want a payroll service provider to simplify the entire process.
Why Payroll Service Numbers Matter for Small Companies
Small businesses often underestimate the complexity of payroll. Unlike larger corporations with dedicated HR teams, small firms usually rely on the business owner or a single employee to manage salaries, taxes, and compliance.
Here’s why finding the right Payroll Service Number UK is crucial:
- Legal Compliance: HMRC requires employers to use their PAYE reference number when submitting payroll data.
- Employee Satisfaction: Paying staff correctly and on time builds trust.
- Avoiding Penalties: Mistakes in payroll can result in fines from HMRC.
- Efficiency: With the right payroll service provider, small businesses save time and avoid administrative headaches.
Step 1: Registering as an Employer with HMRC
Before you can process payroll, you must register your company as an employer with HMRC. Once registered, you’ll receive:
- PAYE Reference Number – Your official payroll service number.
- Accounts Office Reference – Another important code used for tax and NI payments.
How to Register
- Go to the HMRC website.
- Complete the employer registration form.
- You’ll typically receive your number by post within 5–7 working days.
This number is essential—it identifies your payroll submissions and links them to your business.
Step 2: Choosing Between In-House Payroll or Outsourcing
Once you have your Payroll Service Number UK, the next decision is whether to manage payroll in-house or outsource it.
In-House Payroll
- Pros: Full control, direct oversight, lower long-term costs if you already have expertise.
- Cons: Time-consuming, requires payroll software, risk of errors without expert knowledge.
Outsourced Payroll Services
- Pros: Saves time, ensures compliance, access to payroll experts.
- Cons: Monthly service costs, less control over day-to-day processes.
For many small companies, outsourcing is the smarter choice, especially if payroll knowledge is limited.
Step 3: Finding the Right Payroll Service Provider in the UK
If you decide to outsource, the next step is finding a provider that suits your business. When searching for a Payroll Service Number UK provider, consider the following factors:
1. Experience with Small Businesses
Look for providers that specialize in small and medium enterprises (SMEs). They’ll understand budget constraints and tailor solutions accordingly.
2. Compliance Expertise
Payroll involves tax, pensions, and employment law. A provider should guarantee compliance with UK regulations.
3. Transparent Pricing
Avoid hidden charges. Choose a provider with clear, upfront pricing per payslip or per employee.
4. Customer Support
A responsive customer support number is vital. If payroll issues arise, you’ll need quick assistance.
5. Technology & Software
Ensure they use reliable payroll software that integrates with HMRC systems and provides employees with digital payslips.
Step 4: Understanding HMRC Payroll Helplines
Apart from outsourced providers, many small companies also search for HMRC’s payroll service number UK. This is the helpline you can call for direct assistance with PAYE, tax, and payroll issues.
HMRC Employer Helpline
- Telephone: 0300 200 3200
- Availability: Monday to Friday (usually 8 am – 6 pm)
- What They Help With: PAYE reference numbers, PAYE submissions, penalties, queries on National Insurance, and real-time reporting.
If you’re handling payroll yourself, this helpline is an important contact to keep handy.
Step 5: Evaluating Costs for Payroll Services in the UK
The cost of payroll services varies depending on the size of your workforce and the complexity of your payroll. On average:
- Basic Payroll Service: £3–£6 per payslip.
- Comprehensive Payroll Service: £15–£25 per employee per month (including pensions and HR add-ons).
For a small company with fewer than 10 employees, payroll outsourcing can be affordable and save significant time.
Common Payroll Challenges for Small Companies
Even with the right payroll service number UK, small businesses still face challenges. Being aware of them helps in planning:
- Late Submissions – Missing deadlines leads to HMRC penalties.
- Incorrect Tax Codes – Employees may pay too much or too little tax.
- Pension Auto-Enrolment – Employers must legally enrol eligible staff into a workplace pension scheme.
- Record-Keeping – Payroll records must be kept for at least 3 years.
- Changing Regulations – UK tax laws evolve frequently, making it hard to stay compliant without expert help.
Benefits of Outsourcing Payroll for Small Companies
If you’re still unsure whether to manage payroll internally or outsource, here are the top benefits of using a payroll service provider:
- Saves Time: Focus on running your business instead of dealing with tax codes.
- Reduces Errors: Professionals minimize mistakes in calculations and submissions.
- Scalability: Payroll services grow with your business.
- Peace of Mind: Ensures compliance with HMRC and employment laws.
How to Contact Payroll Services in the UK
When searching online for payroll service numbers UK, you’ll often come across contact details for payroll firms. Here’s how to approach them:
- Shortlist Providers – Based on reviews, pricing, and services.
- Request a Free Consultation – Many providers offer free initial advice.
- Ask the Right Questions:
- What’s included in your service package?
- How quickly do you respond to payroll issues?

HMRC vs. Payroll Service Providers – Which is Right for You?
It’s important to understand the distinction:
- HMRC gives you the official Payroll Service Number UK (PAYE reference number) and handles compliance queries.
- Payroll Service Providers manage the actual payroll process for your employees.
Most small companies will interact with both. You’ll register with HMRC and then potentially outsource the day-to-day payroll tasks to a provider.
