Summary of the contracting process

The procurement process for the "District Heating Network Welding Framework" was managed by Nottingham City Council, a sub-central public authority based in Nottingham, United Kingdom. This open competition tender was focussed on the works category, specifically addressing welding services essential for the city’s district heating network. It encompassed general, structural, and pressure system welding, as well as emergency responses. The initial planning started in 2025, and the contract awards were concluded by February 2026. The framework agreement spans four years, from March 2026 to March 2030, following an open procurement method with several successful bidders being small to medium-sized enterprises (SMEs). Key dates include a planned completion of final award signatures by late February 2026, as indicated in the award notices dated 9th February 2026.

This framework presents significant opportunities for SMEs in the mechanical services sector, particularly those specialising in welding, pipefitting, and associated mechanical works. Companies like ACORN MECHANICAL PIPEWORK SERVICES LIMITED, RAYDEN ENGINEERING LIMITED, and SRL ENGINEERING (SOUTHERN) LTD have already been awarded contracts, suggesting the framework’s suitability for businesses with similar capabilities. With an emphasis on planned maintenance and reactive emergency response, this framework enables businesses to engage with and service vital infrastructure projects, offering growth potential through long-term engagements and high-value contracts. Firms equipped to address both routine and complex welding challenges stand to benefit greatly from participating in such public procurement opportunities.
