NRMM Emission Standards - London Regions

As a reminder to the sector, the London NRMM emission standards increase to EU Stage IV as a minimum across all of London from 1st January 2025. Generators are already required to meet EU Stage V emission levels and which will continue to be the case after 1st January 2025.

The Greater London Authority (GLA) ask that any machines which do not comply with the new standards be swapped out before this date. Where this is not possible, the contractor will need to apply for an exemption for that machine, stating the reasons why they cannot swap for a compliant machine.

The standards only apply to machines on construction/demolition sites and only those with a rated engine power between 37kW - 560kW.
