    What our customers say about us

    Above and beyond

    “OnGen went above and beyond what was expected! I feel it’s only right to acknowledge their efforts and offer a huge thank you for the work they’ve done and support they’ve offered!! It really has helped us with a particular client and we would’ve come up short without OnGen!”

    Michael Rossiter
    Operations Director, EC Business Solutions

    Strips complexity away

    “The platform OnGen has created really does help speed up the decarbonisation agenda because it strips a lot of the complexity away that some individuals and companies have benefited from when they shouldn’t have; thus slowing down the green-energy transition.”

    Lebona Vernon
    Client Solutions, ESB
