Make sure your UK employees are paid correctly and on time — every time — with our UK payroll services.

UK tax codes, laws and rules are changing more rapidly than ever before: from a statutory point of view, PAYE payroll has changed more over the past five years than it has in the last 20 years. Over the years, the payroll function has also become increasingly complicated — from managing pension auto-enrolment to furlough (something many businesses had never even heard of before the pandemic). So, the question isn’t should I outsource my UK payroll? The question is: who should I outsource it to?

TopSource Worldwide is one of the leading UK payroll providers with offices in London, Birmingham and Kent. We bring decades of experience and expertise to your operations and have a proven track record of success.

Unlike traditional payroll bureaus that follow strict working structures, we’re flexible and adapt our solutions to suit you. Whether you have 20,000 employees or one employee, it doesn’t matter! We’re experienced with and happy to deliver both small and large payroll — providing a wide range of services that go beyond basic payroll functions.

What our UK payroll clients have to say.

  • Supervisor – Client based in Ft Worth, Texas, USA

    TopSource Worldwide has a detailed and methodical onboarding process that made it easy for us to get set up and running with our UK employee. They were able to take the worry out of trying to comply with all local laws and regulations. Because they have this knowledge we do not have to research on our own and hope we are in compliance. This has saved us hours of time and gives both the company and employees a sense of security.

NI is short for National Insurance and is a deduction from an employee’s wages that goes towards their NI contributions. NI is used to fund state benefits, such as the NHS, and state pensions. NI is calculated based on an employee’s earnings, and the amount deducted will depend on whether the employee is classified as a ‘Contractor’ or an ‘Employee’. NI is deducted by the employer and paid over to HMRC along with the employee’s PAYE (Pay As You Earn) tax contributions. NI is divided into two main categories: Class 1 NI, which is paid by employees, and Class 2 NI, which is paid by self-employed individuals. There are also other types of NI that apply to specific circumstances, such as Class 3 NI, which covers voluntary contributions, and Class 4 NI, which covers self-employed profits.

Yes, absolutely. TopSource Worldwide has adopted best-in-class industry practices to ensure client data is secure. TopSource Worldwide is ISO 9001 and ISO 22301 certified, and our processes are SSAE-18 compliant. These processes and controls are validated annually through independent audits.
