Division Lead
Founding Partner & Managing Director — Energy
Mark is a Founding Partner at Block One specialising in energy procurement and market strategy. Prior to joining Block One as a Founding Partner, he spent over 15 years navigating the UK energy market from the customer's side — not the supplier's. He's built a career on stripping back the noise, educating clients on what actually matters, and delivering procurement outcomes that align to business strategy rather than broker incentives.
From meter installations to portfolio-wide procurement frameworks, Mark operates across the full energy lifecycle. His deep technical knowledge of gas, electricity, water and renewables is matched by a commercial instinct that ensures every recommendation stands up to financial scrutiny.
At Block One, he runs the energy division with a straightforward philosophy: sit on your side of the table, call it how it is, and make sure you're buying with confidence — not confusion. No basket-first thinking, no conflicted fee structures, no volume promises that don't stack up. Just relentless focus on your competitive advantage.

What We Do
We work for you, not the supplier. No hidden margins, no conflicted interests. We call a spade a spade and use deep market experience to cut through the noise and get you unrivalled outcomes.
Extensive technical and market knowledge combined with commercial thinking. Sometimes the simplest product is the right one — sometimes it isn't. We know the difference and we'll tell you straight.
Less cookie-cutter aligned to a broker's goals, more how do we align to your business strategy. We build procurement frameworks around your objectives, not ours.
Clients get thrown into baskets without anyone asking where their strategy sits — then sold flexible hedging because it pays higher fees, not because it's right. We strip it back, educate you through the process, and make sure you're buying with confidence — aligned to your goals, not someone else's.
