The procurement falls under the category of works and covers a wide range of regions across the UK, including England, Wales, Scotland, and Northern Ireland. Key dates for interested parties include a tender period ending on 17 July 2026, with submissions requiring completion through the specified electronic portal. The tender is part of an open procurement process, with an expected framework agreement start date of 1 October 2026, extending up to 30 September 2030, with potential renewal options for an additional year. This framework comprises lots covering various materials such as PVC-U, timber, aluminium, and specialised systems designed for diverse public sector infrastructures like residential, educational, and healthcare facilities. This tender represents significant business growth opportunities for manufacturers with the capability to deliver high-quality fenestration systems adhering to stringent performance, durability, and environmental standards. It is particularly advantageous for small and medium-sized enterprises (SMEs) specialising in innovative window and door solutions, including traditional and contemporary designs. Businesses active in sectors like manufacturing, supply chain logistics, and specialised architectural products will find a substantial opportunity to engage. The framework's emphasis on quality, compliance with safety legislation, and the option to engage in additional call-off contracts throughout its term further enhance long-term business prospects for participating suppliers. ## Notice This framework is intended for organisations with their own manufacturing capability and is not open to installation contractors or distributors without manufacturing facilities.
