Client testimonials
What clients said about the scoping process.
Real comments from operators we have funded. Names and roles published with consent; some company names withheld where the project is in active grant clawback period or pending public announcement.
"Daniel and the team rebuilt our solar project as an integrated decarbonisation package and walked us through the IETF scoring before we wrote a line. The £142k grant award was the difference between an internal hurdle miss and a board-approved capex. Honest, technical, and zero fluff."

"Priya understood public sector procurement better than our framework consultants. We secured 100% PSDS funding across six schools with no trust capex contribution — exactly what the bursary team needed to see. They came in early enough to do the HDP properly, and that bought the award."

"The REPF productivity narrative they wrote was a different category from anything I'd seen from other consultants. They turned a generic decarbonisation pitch into a jobs-and-contract-drying story that the council's economic development team scored top of pile. £62k of grant on a project I assumed wasn't fundable."
