Investment Strategies
The London EDGE Fund.
The London EDGE Fund is an investment fund established by the Greater London Authority (GLA) and Sustainable Development Capital LLP (SDCL) to accelerate London's transition to net zero.
Backed by a £50 million cornerstone commitment from the Greater London Authority, announced by the Mayor of London, Sadiq Khan, the London EDGE Fund is managed by SDCL and remains open to additional institutional investors.
London EDGE provides the capital and expertise to develop, build and operate clean energy infrastructure on behalf of energy users. It offers a range of delivery models, including energy-as-a-service, so customers can benefit from lower costs, greater resilience and reduced emissions without upfront investment.
EDGE Investment Areas
Energy efficiency and building retrofit
Upgrades that cut energy use and running costs across large buildings and estates, such as LED lighting, building management systems (BMS) and HVAC upgrades. These are well suited to hospitals, universities, schools, local authority estates and commercial buildings.
On-site generation and storage
On-site solar PV, battery storage, heat pumps and CHP (using green gas). These can be delivered alone or combined into a behind-the-meter microgrid that supplies reliable, low carbon power directly to the site. Examples include hospitals, cultural institutions and hotels.
For data centres, EDGE can fund and deliver behind-the-meter power solutions, including on-site generation, battery storage and backup power. These work alongside the grid connection to improve resilience, help manage grid constraints and reduce emissions.
Heat decarbonisation and district energy
New low carbon heat networks and the decarbonisation of existing gas-fired networks. These serve large estates, campuses, landowners and local authorities.
Low carbon transport
EV charging and the enabling grid infrastructure, including public rapid charging networks and fleet and depot charging. In 2026, London EDGE agreed a £10 million facility with EVN to roll out rapid EV charging across London.
These are examples of the technologies in which the Fund can invest; other technologies may also be considered. All technologies the Fund deploys must be proven and commercially deployed (TRL 9).
The EDGE Model
The Fund works with each customer to design the most suitable delivery model. The Fund sets up and capitalises a dedicated special purpose vehicle (SPV) for each project, usually providing all or most of the project equity. It then manages the project through development, construction and operation.
