The procurement, completed through a competitive flexible procedure, resulted in a contract award notice dated 27th May 2026, with services set to commence on 8th June 2026, extending initially until 31st May 2029, with options for subsequent renewals. This contract presents additional opportunities for businesses specialising in engineering design validation, particularly those with experience in the utilities sector and capable of navigating regulatory and technical standards in hydrogen technology. Companies with expertise in designing and assuring infrastructure reliability, safety integrity, and risk mitigation would be well-equipped to partake in this framework. This setting enables businesses to form collaborations with a pivotal player in the UK's transition to sustainable energy solutions, reinforcing their industry presence and fostering business growth in the burgeoning field of hydrogen energy. ## Notice Northern Gas Networks Limited (NGN) has established a framework agreement for the provision of specialist Design Validation and Assurance services in support of the East Coast Hydrogen (ECH) programme. The ECH project is a major infrastructure initiative to develop a hydrogen transmission and distribution network across the North East of England, supporting the transition to a low-carbon energy system and the UK's net zero targets. This Contract Award Notice relates solely to Lot 6 - Design Validation & Assurance. This lot provides independent technical assurance of engineering design outputs across the lifecycle of the ECH programme, including the Front-End Engineering Design (FEED), Development Expenditure (DEVEX), and subsequent phases. Services delivered under Lot 6 include, but are not limited to: independent validation of design compliance with applicable regulatory, safety, and technical standards; review and assurance of engineering design outputs including network architecture, pipeline systems, above-ground installations, and control systems; and verification of safety integrity, hazard studies, and risk mitigation measures. The appointed supplier(s) will provide structured assurance through stage-gated reviews, ensuring traceability from requirements through to design outputs, and confirming that designs are safe, compliant, and aligned with best practice. This includes assessment of constructability, operability, maintainability, and interface management across the project.
