Consultant Environmental Due Diligence

Are you motivated to identify EHS and ESG risks and translate them into clear, transaction-focused advice that helps clients make informed buy‑side or sell‑side decisions? Do you enjoy supporting Phase I Environmental Site Assessments and ESG reviews—combining desk research and site visits—to produce concise, client-focused due diligence reports? Are you organised and collaborative, able to support project management and proposal development while coordinating specialist inputs to meet tight M&A deadlines?

If this sounds like you, then this role could be a perfect opportunity. Join our CST Due Diligence UK & Ireland team as our new Environmental Consultant for Due Diligence and help close the gap to a sustainable future.

As an Environmental Consultant for Due Diligence (DD), you will be part of our busy UK transactions team supporting fast-paced UK and global M&A transactions. You will assist with the identification of key EHS and ESG risks and opportunities and provide high-quality, targeted advice to clients on both buy‑side and sell‑side due diligence projects.

Our team advises on transactions across a wide range of sectors, typically including industrial, commercial and infrastructure assets and businesses, often for finance sector clients. We work closely with in‑house specialists across several EHS and ESG disciplines to provide targeted due diligence advice. Our clients use this advice to support negotiations during the bidding process and to make informed, impactful decisions on sustainability priorities post‑acquisition.

You will play a key role in the team, principally delivering due diligence assessments, while also supporting project management and the development of client proposals.
