Summary of the contracting process

The procurement process for the framework agreement titled "FW Works - GD3 Repex Tier 1 - Southern 0330" was undertaken by Southern Gas Networks (SGN), aimed at appointing contractors for gas distribution mains and services replacement work across multiple regions in Southern England. This comprehensive project, classified under the CPV code 45231000 for construction work for pipelines, involved four lots covering areas such as Poole and Solent, Oxford and Aldershot, Epsom, Orpington and Godstone, and Horsham and Ashford, with annual delivery targets ranging from 119 km to 177.73 km. The procurement used a selective method with a negotiated procedure and was completed by May 2026, with the contracts set to last until March 2031, with possible extensions. The key procurement stages involved a tender process and subsequent contract awards on 1st April 2026.

The framework agreement structure offers a five-year commitment with the possibility of extensions, paving the way for sustained revenue streams and potential scaling of operations. Businesses such as I&G Contractors Ltd, WCB Utilities Limited, and others specialising in large utility infrastructure works have been successful in securing contracts across different lots, indicating the suitability for established players with substantial resources and expertise. The free issuance of PE pipes and fittings by SGN further incentivises participation by minimising material procurement costs and streamlining the completion of the contracted works.
