Built on real project experience

OMG Energy was founded by Alex Gray, a NatHERS assessor and building performance specialist with experience across residential and multi-residential developments. Working closely with architects, builders, and consultants, Alex focuses on delivering modelling that not only meets NCC 2022 requirements — but aligns with real construction outcomes.From early design through to final documentation, the goal is simple:
Achieve compliance without overdesign or costly redesigns
