Who’s Behind

Brentnall BCA and Why It Matters

Most of our clients don’t need someone to read them the NCC, they need someone who’s already read it, argued it, and applied it on real projects like theirs.

Mark Brentnall

Founder & CEO of Brentnall BCA

Brentnall BCA is led by Mark Brentnall, a registered unrestricted certifier with 25+ years of experience, and one of the few consultants who still give straight answers.

Having spent years as a statutory certifier, his experience now shapes the way he consults. He knows what certifiers and councils expect, and what they don’t want to see.
