The process is in its planning stage, with key market engagement scheduled for the 30th of March 2026, to take place at Roundthorn Country House, Penrith. This initiative aims to establish a multi-lot framework to serve nuclear and non-nuclear demands, offering services across regions including UKC through UKK. The procurement seeks suitably qualified suppliers to deliver diverse services, such as precision machining and specialist fabrication, crucial for both component manufacturing and repair activities. This tender presents significant growth opportunities for businesses specialising in fabrication and machining, particularly those offering nuclear reactors and parts, HVAC packages, and metalworking services. The framework is structured to accommodate small and medium-sized enterprises (SMEs) as well, fostering competitive participation. The framework agreement technique, with a gross value of up to £12 million, promises long-term engagement, extending potentially to 2035. Businesses with capabilities in quality inspection and documentation services are well-positioned to leverage the framework to expand their operational footprint and engage with the public sector's evolving needs. ## Notice United Kingdom National Nuclear Laboratory is undertaking pre-market engagement to inform the development of a Fabrication and Machining framework, structured as a multi-lot arrangement to support both nuclear and non-nuclear requirements.
