Former Sizewell C MD Julia Pyke joins infrastructure advisory firm Agilia as Chair
Julia Pyke will join Agilia Infrastructure Partners as Executive Chair on 2nd April 2026.
Julia Pyke, former Joint Managing Director of the Sizewell C nuclear power project, has been appointed Executive Chair of the infrastructure advisory Agilia Infrastructure Partners.
Agilia, led by joint-CEOs and co-founders Mike Pugsley and Amar Qureshi, currently supports infrastructure programmes with a combined capital value of more than £100 billion. The firm advises governments, regulators and investors on the development and delivery of complex infrastructure projects across energy, water, transport and defence.
Pyke previously helped steer Sizewell C through planning consent, its Final Investment Decision (FID), and Financial Close, working with government and investors to take the new nuclear power station into full construction. During her tenure, the project also secured an investment-grade credit rating and achieved the world’s first financing of a new nuclear construction project. The project is expected to generate around 7% of the UK’s electricity once operational.
Her appointment comes as the UK prepares to deliver a new generation of energy, water and transport infrastructure projects which are expected to require hundreds of billions of pounds in investment and create thousands of jobs - work in which Agilia is already deeply embedded.
A Cambridge graduate, Pyke has spent more than a decade working on major nuclear infrastructure projects across the UK. Pyke is a Clean Power Commissioner for the UK Government and a non-executive director of Studsvik, a supplier of equipment and consultancy services to the nuclear industry, which has recently expanded into the development of new nuclear projects through the acquisition of an SMR project developer. She is a Fellow of both the Energy Institute and the Nuclear Institute.
Pyke succeeds James Stewart OBE, who will conclude his tenure as non-executive Chair at the end of March after helping guide Agilia’s development over the last three years. Stewart recently led the government-sponsored Stewart Review into major infrastructure projects, published last year, which has influenced the debate around how major projects should be developed and delivered in the UK and across Europe.
Julia Pyke said:
“The UK is entering a once-in-a-generation period of rebuilding and renewing our infrastructure. These are the projects that shape a country’s future, and getting them from vision to reality takes experience, determination and the right people around the table.
“Working with Agilia at Sizewell C, I saw first-hand the value of their practical, real world project experience in turning big national ambitions into projects that can actually be delivered.
“I’m thrilled to be working alongside Mike and Amar and the rest of the Agilia team as it helps deliver the infrastructure that will support the country’s prosperity and resilience for generations — from the power that keeps the lights on, to the water and transport systems our communities depend on every day.”
Amar Qureshi, Co-Founder and Joint Chief Executive Officer of Agilia Infrastructure Partners, said:
“The UK has the ambition and capital to deliver some of the most important infrastructure projects in a generation. What matters now is having the leadership and experience to turn those plans into projects on the ground.
“Julia is one of the few people who has helped take a project on the scale of Sizewell C from vision to full construction. Her values, experience and skills complement our own expertise in bringing together developers, government, investors and industry to deliver complex, nationally significant projects. Julia joining our team reinforces our ambition to continue supporting the delivery of the UK’s next wave of major infrastructure.”
Mike Pugsley, Co-Founder and Joint Chief Executive Officer of Agilia Infrastructure Partners, added:
“As we start this new chapter, we want to thank James Stewart as outgoing Chair, for sharing his expertise and support, which have been central to Agilia’s development and ongoing rapid growth. We established Agilia to combine public and private sector expertise in a way that helps unlock infrastructure delivery, and that remains our focus.
“Julia shares our belief in the transformative power of infrastructure, and in delivering long-term value for money, for customers, investors and the taxpayer.”
James Stewart OBE said:
“Agilia has established itself as a trusted adviser on some of the UK’s most significant infrastructure programmes. It has been a pleasure to support the business and its growth over the past three years. I wish Agilia, and Julia in her new role, every success as they continue that journey.”
Anne Tiedemann, Chair of Agilia’s Employee Owned Trust, said:
“Agilia’s employee-owned structure means the development of our people is central to the long-term success of the business. Julia Pyke brings leadership, expertise, and experience from some of the UK’s most significant infrastructure projects which will strengthen the capability of Agilia’s diverse team and service to our clients as the company continues to grow.”
