What is RM6390?
RM6390 Energy and Decarbonisation Services is the next-generation energy agreement from the Government Commercial Agency (formerly Crown Commercial Service). It brings the supply of electricity and gas together with the services the public sector needs to manage and decarbonise its energy use: partnership and consultancy services, bureau services, metering, and enhanced Power Purchase Agreements for renewable generation.
The framework replaces RM6251 Supply of Energy 2 and aggregates approximately £50 billion of public sector energy procurement, which makes it one of the largest commercial agreements in UK public procurement. Buyers will range from central government departments to NHS trusts, councils, schools and housing providers.
When does the RM6390 tender open?
The Government Commercial Agency lists the Find a Tender notice for RM6390 as expected in July 2026, with framework award scheduled for December 2026. That is a short procurement window by framework standards, which rewards suppliers who prepare their evidence before the notice appears.
Because the framework is let under the Procurement Act 2023, expect published evaluation criteria, a structured question set and mandatory exclusion and financial standing checks. Suppliers who wait for the notice to start preparing routinely run out of time to gather accreditations, case studies and carbon reduction plans.
