Summary of the contracting process

Northern Gas Networks Limited procured gas pipeline construction and maintenance works to expand its Direct Service Provider framework. The scope covers natural gas and hydrogen networks, including replacement, abandonment, reinforcement, diversion and connection of mains and services; polyethylene and steel mains up to 1,200mm and services up to 63mm; riser works; low, medium and intermediate-pressure connections; surveys, trial holes, camera surveys, backfill and reinstatement. Suppliers may also support planned and emergency gas repair and response work. Desirable capabilities include live service insertion, service extraction, bulk renewals, district governor work, specialist flow stopping, deep excavations and appliance purge and relight. Work is delivered across England, including the North East, North West, Yorkshire and the Humber, Midlands, East, London, South East and South West.

This completed selective procurement used a competitive flexible procedure for one framework lot. The framework was evaluated through pass/fail participation conditions, a PQQ requiring a score above 60%, and an RFP requiring at least 60% for non-commercial criteria, alongside price and contractual quality criteria. The estimated framework value was £60,000,000 gross. The award was made on 27 August 2026 to T G Pipelines Limited, Stobbarts Ltd and Mole Tech Solutions Ltd, with an awarded value of £60,000,000 gross (£50,000,000 excluding tax). The contract period runs from 10 September 2026 to 12 March 2029, with an extension option to 12 March 2032. The framework uses reopening competition for subsequent contracts and is suitable for SMEs.

This award shows sustained demand from Northern Gas Networks for multi-skilled gas network contractors able to provide both planned delivery and emergency response. Credible competitors would need practical capability across mains and service replacement, abandonment, reinforcement, diversion, connections, risers, pressure-system work, surveys, excavation, reinstatement and customer-related emergency repairs. Experience with both polyethylene and steel assets, work on natural gas and hydrogen networks, and compliance with Northern Gas Networks technical standards and procedures would be important. Additional strength would come from district governor installation, live service insertion, specialist flow stopping, deep excavation, bulk renewal and appliance purge and relight capabilities. The requirement is suitable for SMEs, but suppliers would need enough trained engineers, teams and operational capacity to support network-wide delivery.
