This role is aimed at someone who wants more than just delivery.

You are likely to bring: A background in sustainability, energy or carbon consultancy Strong technical credibility in carbon and building performance Experience dealing directly with developers, architects and project teams The confidence to challenge, influence and guide clients An interest in developing people and building teams A commercial mindset, not just a technical one What’s on offer This is a consultancy that is investing heavily in its next phase of growth, with clear progression routes for people who want to lead.
