The Nuclear Industry’s
Preferred Partner


We are the nuclear industry’s preferred partner for engineering, waste management and decommissioning solutions. Our four decades of proven delivery and technical expertise are underpinned by our values-led and people-oriented working culture, which enables us to attract and retain the best talent. As a project delivery business, we work in collaboration with our clients and partner companies to drive value, deliver what we promise and safely solve some of the nuclear industry’s most complex and challenging problems.


With a proven track record of safely and securely completing projects and programmes across the nuclear project lifecycle, we are trusted by our customers to deliver on time and to budget.


The environment, health and safety, security and quality are fundamental to everything we do. Our values, processes and procedures work to instil the internationally accepted principles and traits of a strong nuclear safety culture. We collaborate with our clients to support the safe and efficient provision of robust and underpinned solutions to achieve certainty of delivery and a successful project outcome. Our approach is based on the utilisation of suitably qualified and experienced personnel (SQEP) to carry out activities in accordance with approved procedures and applicable legislation in a safe, auditable and cost-effective manner.

We have an excellent safety record and our personnel are trained to understand the importance of, and compliance with, both nuclear and conventional safety legislation. All our projects are executed using a company-wide standardised structure, ensuring a safe and consistent approach to delivery. Our structure is also designed to work safely in accordance with our clients’ site-specific safety standards.
