The Mayor of London's Energy Efficiency Fund

Funds
MEEF, established by the GLA with funding from the European Commission, has sought to address market failures in London’s low carbon sector by providing flexible and competitive finance to enable, accelerate or enhance viable low carbon projects across London.
MEEF has built on the success of the GLA’s London Green Fund including the Amber managed London Energy Efficiency Fund (LEEF).
Since its launch in July 2018, MEEF has contributed towards London’s ambition of being a net zero carbon city by 2030. Through investment in 24 projects across various boroughs, MEEF has reduced more than 38,000 tonnes of CO2 emissions—an impact comparable to removing 34,675 vehicles from the city's roads.
MEEF’s investment period officially came to an end in 2025 after a successful seven-year run, including two extensions and additional contributions from public sector partners in view of the Fund’s strong performance.
These include electric vehicle charging infrastructure combined with energy storage, a retrofit of a district heat network with water source heat pumps, one of London’s largest district heating networks, as well as an energy performance contract with guaranteed savings and a flexible payment mechanism to support London’s taxi fleet operators in their decarbonisation.
