About Us
01Engineering Leadership
Phase Design is led by experienced rail engineering professionals with chartered capability and a proven track record delivering complex infrastructure projects across safety-critical environments.
02Integrated Approach
We bring together electrification, civils, power systems and multidisciplinary coordination to ensure compliant, buildable and fully integrated engineering solutions.
03Delivery-Focused Mindset
Our focus is always on practical implementation — reducing risk, supporting programme certainty and ensuring designs transition efficiently from concept through to construction.
About Phase Design
Phase Design was established to provide experienced, director-led engineering support to complex infrastructure projects.
Our team brings extensive knowledge of rail systems, electrification and power integration, developed through years of working within highly regulated and technically demanding environments.
While rail remains central to our expertise, we also support projects across wider infrastructure sectors such as Highways, Water, Data Centres, Airports & energy. Sectors where strong engineering governance, multidisciplinary coordination and technical assurance are critical to successful project delivery.
We are a technically focused consultancy, built on practical experience rather than theory. Our directors and engineers have worked across multidisciplinary rail programmes, supporting clients through complex interface environments, evolving standards and live operational constraints.
Our approach is grounded in clarity, accountability and collaboration. By working closely with clients, contractors and stakeholders, we ensure engineering decisions are informed, risks are understood early and solutions are delivered with confidence and technical integrity.
Our Expertise Across Rail Infrastructure
Phase Design has supported projects involving AC and DC electrification systems, HV and LV power distribution, rail civils integration and multidisciplinary interface coordination.
Our experience spans design development, technical assurance and approvals within live operational railway environments where safety, compliance and programme alignment are critical. We understand the complexities of working across interconnected systems and the importance of structured engineering governance in delivering infrastructure that performs as intended.
Our involvement typically spans early-stage design development through to detailed engineering, technical verification and stakeholder approvals. We work closely with asset owners, contractors and project teams to ensure system interfaces are clearly defined, design risks are managed proactively and engineering outputs align with operational and regulatory requirements.
We recognise that rail infrastructure projects demand more than technical accuracy alone. Successful delivery depends on structured coordination across electrification, civils and power disciplines, alongside a clear understanding of construction sequencing and live railway constraints. Our experience enables us to contribute effectively within complex project environments while maintaining technical clarity and accountability.
While our heritage is rooted in rail, our design capability extends across multiple infrastructure sectors. Our directors bring extensive experience in safety-critical environments, complex electrical systems, and multidisciplinary coordination — enabling us to support projects wherever resilient power, distribution and infrastructure integration are required. Here's a quick overview of the sectors we operate in:-
