Oak provides an independent energy concierge service to businesses wanting to get control of their footprint and use the data generated to help them deliver a net zero strategy.


Oli’s feedback was useful and impactful. The questions and entire conversation were very relevant, and always very respectful of our vision. His aim was not to tell me the impossible but to challenge me on how far you can really scale for impact. I feel the OAK Network clearly found a strong ally in Oli, and Expert Impact made it happen extremely quickly.
