Climate ER is a specialist consultancy guiding renewable energy projects through UK development.

Why Climate ER?

Deep industry expertise

With over 20 years in UK energy, infrastructure, and major development, we’ve successfully delivered 1GW of solar and BESS projects and 500MW of onshore wind.

Commercially grounded
We understand how investors think — and how development decisions create or erode value.

Process-led, not chaos-led
Our bespoke OneDevFlow process integrates common software to replace instinct with data, bringing discipline and clarity to development.

Aligned and independent
Free from conflicts and corporate noise, we provide clear, rigorous, unbiased advice.

Boutique, senior attention
You work directly with seasoned experts — never handed off to junior teams.

We understand the development process inside-out — because we’ve lived it from origination to exit.

Now we apply that experience to make your projects faster, cleaner and more investable.

How Can We Help?​

We support renewable energy and critical infrastructure developers and investors throughout the UK development lifecycle, from early-stage site origination to planning, commercial structuring and transaction readiness. Our work spans development strategy, land, planning, risk management and investor due diligence, helping clients de-risk projects, sharpen decisions and accelerate delivery at critical stages.

Alongside advisory support, we design disciplined development processes through OneDevFlow — our bespoke, embedded approach to workflow, governance and reporting. By bringing clarity, transparency and control to complex portfolios, we give developers, Boards and investors a clear view of progress, risk and value creation.
