About Us

Our mission? Result driven HR.

We excel in Human Resources services that drive your business performance.

Following the acquisition of Ceridian UK & Ireland in June 2016, SD Worx has strengthened its position as one of the largest payroll providers in Europe. SD Worx provides technology and services that supports the entire employee life cycle, including payroll, HR and workforce management. With over 70 years’ experience and the best people in the industry, we help customers reduce costs, improve compliance and increase profitability. Our goal is to help your business grow by giving your employees the insights, tools and support they need to succeed. It’s much more than human resources management. It’s about supporting the greatest asset of all; your people.

In the UK & Ireland, we have over 50 years’ experience delivering payroll and HR solutions to over 2,400 customers, including some of the world’s largest brands.

Gender Pay Gap Report 2017

In our report, we provide our gender pay gap information; identify the causes of the pay gap and outline our plans for closing this gap.

At SD Worx, we have an ambition to be the most desired brand in our sector, we know to achieve this, it’s essential we foster, celebrate and promote the benefits of a truly inclusive and diverse workplace.

In summary, our report findings highlight we have more to do to close the gap further at a more senior level and in more highly technical roles. Women make up just over 53% of our colleagues across the UK, more than 25% of our UK Senior Executive Team, and 40% of our UK Board. We are proud of the progress we have already made towards gender equality in our business and have a number of initiatives in place to help further close the gap. Though we recognise this will take time and there’s still a lot to do.  

We are fully committed to ensuring SD Worx is the company, top talent want to work for by providing opportunities for all, regardless of gender or background.
