DELIVERING VALUE RESPONSIBLY
Every Diploma business is unique. Our Delivering Value Responsibly (DVR) framework focuses on three themes through which we can have a meaningful impact. This shared framework empowers local teams to lead the change, backed by the tools and guidance they need. It's the balance of independence and support that makes our model powerful.
Delivering for our people
Empowering people to grow and succeed in a supportive, entrepreneurial culture.
Diversity, equity and inclusion
We are committed to fostering an inclusive culture. Our ambition to increase female representation in the Top 150 to 40% by 2030 supports our wider goal of developing diverse talent from within. We’re also ranked among the top three FTSE 100 companies for year-on-year progress (FTSE Women Leaders Review 2025).
