Phoenix Energy Responsible Business Report 2026

The energy sector continues to operate within a period of significant change, with the need to balance affordability, resilience and sustainability more important than ever. Against this backdrop, 2025 has been a year of strong and purposeful delivery for Phoenix Energy, demonstrating the value of long term investment, operational excellence and collaboration across our business and wider stakeholder community. Throughout the year, our priority remained the safe, reliable and efficient operation of Northern Ireland’s largest gas distribution network. In 2025 our customer teams handled over 60,000 telephone calls , and responded to more than 30,000 written customer enquiries , reflecting both the scale of our operations and our continued focus on accessible, high quality customer service. Delivering a high performing Responsible Business programme remains firmly embedded within our culture and reflected across a wide range of established initiatives. The breadth and impact of the activity captured in this report is driven by the professionalism and commitment of our colleagues, supported by strong partnerships with our stakeholders. As this report demonstrates, Responsible Business considerations are integrated throughout every aspect of our operations from how we plan and deliver construction works, to how we engage with stakeholders and invest in the development, wellbeing and capability of our people. We were delighted to report that in 2025 we retained our Gold Standard in Business in the Community NI’s ‘CORE’ accreditation, received 100% and were once again awarded a 5-star rating GRESB Infrastructure Asset Benchmark Report, in which we placed joint 1st globally and we retained Platinum-level in the NI Environmental Benchmarking survey (BITC) , which we have been participating in for over 25 years. Providing an inclusive service that meets the needs of all consumers continues to be a core priority for Phoenix Energy. Building on the award of the Consumer Vulnerability ISO 22458 accreditation in 2024 , we have continued to raise the bar in this area throughout 2025. Our internal Vulnerability Working Group meets regularly, bringing together colleagues from across the business I am proud to lead a company that continues to place Responsible Business at the heart of how we operate. By strengthening our environmental, social and governance commitments, we create a positive and inclusive working environment that enables our people to deliver lasting value for the customers and communities we serve. This commitment shapes our decisions, our culture and the way we deliver essential services every day. Foreword from our CEO

to share learning, strengthen capability and ensure that inclusive service delivery remains embedded in day to day operations. This continued focus is driving meaningful improvements and reinforces our ambition to set new benchmarks in supporting customers with additional needs. 2025 was also a positive year for market development, delivered in a way that supports long term sustainability and customer choice. We laid over 20km of new mains , enabling access to natural gas for a further 2,000 properties , and delivered 5,000 new connections . This continued growth supports regional economic activity while aligning with our longer term pathway to decarbonisation and the evolving role of the gas network in a lower carbon energy system. Across all areas of our operations, the scale and complexity of delivery was significant, involving in excess of 50,000 working hours , extensive traffic management across 60 major junctions , and the distribution of approximately 250,000 public communications. Importantly, our construction and maintenance activities continued to demonstrate strong environmental stewardship. While performance and delivery are critical, our success is ultimately driven by people. The achievements outlined in this report are only possible because of the dedication, expertise and teamwork shown by colleagues across Phoenix Energy, alongside the valued support of our delivery partners, regulators, stakeholders and community representatives. I would like to thank everyone who contributed to our work during 2025 and, in doing so, helped us continue to serve our customers and communities safely, inclusively and responsibly. I am proud of what has been achieved over the past year and confident that Phoenix Energy remains well placed to respond to future challenges and opportunities, while staying true to our vision of being recognised for excellence as a world leading energy utility.
