About us

We are Zellis, the UK & Ireland’s leading payroll and HR software and service provider.

Our history

You’ve known us previously as NGA Human Resources UK and Ireland. Today we are Zellis. Over 50 years ago Peterborough Data Processing Limited was founded and grew quickly, changing names a few times along the way.

As Northgate in 2007 Arinso was acquired and became NorthgateArinso. This in time simplified to NGA Human Resources.

In February 2018 the UK & Ireland division was sold to operate as a standalone company – That’s us, Zellis.

We continue to partner with our former parent company to serve the needs of global customers in the UK and Ireland.

A lot has changed in 50 years, we’ve been leaders through it all and we’re ready for what’s next.

Our vision

Now, we're in direct control of our business. It’s an exciting time for us and our customers too.

We have supportive shareholders committed to developing the business for the long term. We will be making significant investments to further enhance our technology and services, with exciting developments in areas like robotics and AI.

Our focus will be on delivering successful partnerships with customers. We want to work closely with you to help you achieve better employee experiences and deliver successful business outcomes.

Zellis might be a new name, but we are a strong and long-established company and we aim to remain at the forefront of our industry.
