Ian Williams, Axis Europe, Cardo (South), T Gilmartin and Wates Property Services have landed places on the single-lot deal, which covers Greater London and some surrounding areas.
The housing association will call off work using JCT measured term contracts. Each call-off could run for up to 15 years.
NHG said the long-term deal is designed to improve service levels, allow work to be switched between contractors if delays occur, and keep competitive pressure on delivery standards.
The framework’s £1.5bn value is based on NHG’s own £600m projected spend plus up to £900m in third-party call-offs from other users.
