What's the difference between a strategy consultant and what Block One does?

Most strategy consultants deliver a report and walk away. We build ROI-driven investment cases that get board sign-off and identify funding routes to get projects delivered — not shelf-ready PDFs.

Do I really need an investment case for a net zero project?

If you want it funded, yes. Sustainability mandates alone rarely unlock capital. What does is a clear commercial narrative — payback periods, IRR, avoided costs, regulatory risk mitigation, and asset value uplift.

How do you make sustainability commercially viable?

By treating it as a financial opportunity, not a compliance burden. We identify where decarbonisation, efficiency, and regulatory changes create margin.

What sectors do your strategy engagements typically cover?

We specialise in the living sectors (PBSA, Co-Living, BTR, Senior Living), data centres, and infrastructure.

How long does a Review take?

The core review process takes 2–3 weeks from briefing call to debrief. The on-site session itself is 3–4 hours.

What's MEES 2026 and should I be worried?

The Minimum Energy Efficiency Standards (MEES) are tightening in 2026, raising the minimum EPC requirement for commercial properties.

Can you help if we've already got a sustainability strategy but it's not delivering?

That's exactly where we add the most value. We audit what's been done, identify where the gaps are between intent and execution, and rebuild the commercial case.

What's the difference between a strategy consultant and what Block One does?

Most strategy consultants deliver a report and walk away. We get projects over the line — building investment cases that win board conviction, or finding alternative funding and no-capex routes that remove the barrier entirely. We stay involved through execution because the advice is only as good as the outcome it produces.

Is your strategy work always sustainability-led?

No. A large share of our strategy work is purely commercial — transforming how a business buys, uses and contracts for energy and infrastructure to drive measurable financial benefit. That can mean restructuring procurement, exiting bad contracts, repricing risk, rebuilding the operating model, or unlocking trapped value inside an existing portfolio. Carbon and ESG outcomes often follow, but they're not the trigger. The trigger is margin, payback and asset value — and we're equally happy engaging on those terms alone.

Do I really need an investment case for a net zero project?

If you want it to happen, yes. Sustainability mandates alone rarely get projects moving. What does is a clear commercial narrative — payback periods, IRR, avoided costs, regulatory risk mitigation, and asset value uplift. We build the case that gets board sign-off, and where capex is the blocker, we find alternative funding routes that remove it. We speak the language of CFOs and investment committees, not just sustainability teams.

How do you make sustainability commercially viable?

By treating it as a financial opportunity, not a compliance burden — and being honest that sustainability isn't always the driver. Often the impact we're solving for is cost-driven payback, hard-edged valuation improvement, or the sustainability of the business itself rather than a carbon target. We identify where decarbonisation, efficiency and regulatory changes create margin — reduced operating costs, improved EPC ratings, avoided penalties, enhanced asset values and access to green finance. Every recommendation comes with a number attached.

What sectors do your strategy engagements typically cover?

We specialise in the living sectors (PBSA, Co-Living, BTR, Senior Living), data centres, and infrastructure — but our Review process works for any organisation with complex energy or infrastructure positions. The common thread is assets where energy and sustainability directly affect value.

How long does a Review take?

The core review process takes 2–3 weeks from briefing call to debrief. The on-site session itself is 3–4 hours. We move fast because speed is a competitive advantage — most of our clients can't afford to wait quarters for a recommendation when the market is moving now.

What's MEES 2026 and should I be worried?

The Minimum Energy Efficiency Standards (MEES) are tightening in 2026, raising the minimum EPC requirement for commercial properties. If your assetthe case to get compliance projects over the line — whether through board-approved capex or no-capex funding routes that remove the barrierre, prioritise upgrades by ROI, and build funded pathways to compliance — turning a regulatory risk into an asset improvement opportunity.

Can you help if we've already got a sustainability strategy but it's not delivering?

That's exactly where we add the most value. We audit what's been done, identify where the gaps are between intent and execution, and rebuild the commercial case. Often the strategy is fine but the implementation pathway — funding, procurement, sequencing — is where things stall. We fix the execution, not just the plan.

BLOCK ONE®

Strategy

Investment cases, infrastructure advisory and commercial models that get projects over the line — whether that means building board conviction or finding a no-capex route forward.

Division Lead

AJ Walker

Founding Partner & Strategy Director

Prior to joining Block One as a Founding Partner, AJ built his career on the front line of energy strategy and infrastructure investment — advising asset managers, developers and occupiers on how to extract maximum commercial value from complex, regulation-heavy environments.

He thrives on weaving genuine long-term strategy into wider business activities — blending solutions and finding ways to make renewable energy and sustainable choices make commercial sense. He asks questions, poses options and structures pathways to find the best answer for your business, not the easiest one.

His approach is unapologetically commercial. Where others produce reports, AJ builds investment cases that unlock capital. He's led strategic reviews across data centres, living sectors and mixed-use portfolios — consistently delivering credible, successful change programmes that beat the market on both top and bottom line.

AJ loves a fresh challenge — the tougher the better. He uses both statistics and personal insight to understand situations from all angles, then compresses the gap between insight and execution. His financial modelling capability, combined with deep legislative knowledge, means clients don't just understand their options — they act on them, fast.

What We Do

Core Capabilities

Commercial DNA

Every recommendation we make is built on commercial rigour. We don't just advise — we build convincing ROI arguments and financial models that get sign-off fast and hold up under scrutiny.

Rapid Delivery

Speed is a competitive advantage. We compress timelines that others stretch over quarters into weeks — getting projects from concept to execution before the market moves on.

Investment Modelling

Decision-ready investment cases that translate technical complexity into clear commercial narratives — built to get board sign-off or identify alternative funding and no-capex routes that remove the barrier entirely.

The Black Ops of Sustainability

We're here to make impact — and that impact isn't always sustainability-led. More often it's cost-driven paybacks, hard-edged valuation improvement, or the sustainability of your actual business that's at stake. We operate in the space between regulation and advantage, solving for the number that matters most.
