At Iron Mountain, we foster an environment characterised by teamwork, bravery, and a deep focus on customer satisfaction, principles that guide every employee. Our collective effort is to build an inclusive workplace where everyone's true self is embraced and valued. By embracing a variety of thoughts, experiences, and viewpoints, we spark innovation. This approach not only enables our employees to flourish but also enhances our customer experience and drives the success of our business.
Our Progress in 2025
Building on the foundation laid in 2024, we have continued to leverage our Employee Resource Groups (ERGs) as a primary engine for cultural and structural change. Throughout 2025, these groups have remained the heart of our inclusion strategy, fostering a sense of belonging and ensuring that the diverse voices of our "Mountaineers" are heard at every level of the organization.
We believe that the sustained engagement of our ERGs, particularly Women@IM, combined with the rigorous oversight of our Rewards team, has been instrumental in the continued narrowing of our gender pay gap this year. By aligning our internal community support with equitable reward frameworks, we have ensured that career progression and compensation remain transparent, fair, and accessible to all.
Looking Ahead: 2026 and Beyond
As we look toward 2026, our commitment to achieving total gender parity remains unwavering. We will continue to evolve our ERG initiatives to meet the changing needs of our workforce, ensuring they remain a platform for professional development and advocacy.
In the coming year, we intend to further integrate the insights from our ERGs into our long-term talent and reward strategies. Our focus remains on accelerating the pipeline of female talent into senior leadership and maintaining a culture where every employee, regardless of gender, has an equal opportunity to thrive, lead, and be rewarded for their contributions.
Peter Long, (Head of Operations UK, Ireland and South Africa) said
At Iron Mountain, our commitment to achieving total gender parity remains unwavering as we foster an inclusive workplace where every "Mountaineer" is empowered to thrive. Building on the foundation of our previous efforts, I am pleased to report that our 2025 data shows a significant narrowing of the gender pay gap across both our UK entities, Iron Mountain (UK) PLC and Iron Mountain (UK) Services Limited.
These results are a testament to our dual strategy: leveraging our Employee Resource Groups, specifically Women@IM, to drive cultural change while maintaining rigorous oversight of our equitable reward frameworks. While we are proud of these improvements, particularly the significant reduction in the bonus gap within Iron Mountain (UK) PLC, we are not complacent. We recognise that there is still work to be done to close remaining gaps and to continue to genjavascript:void(0);erate the pipeline of female talent across all roles. As we look toward 2026, we will continue to refine our recruitment and internal progression strategies to ensure that compensation and career development remain transparent, fair, and accessible to all, regardless of gender.
