Consultant/ Senior Sustainability Consultant (LCA & CE)

A fantastic opportunity to join a growing sustainability consultancy based in Central London, supporting developers, architects, engineers and contractors in delivering low‑carbon, future‑ready buildings. Due to continued growth of their embodied carbon and circular economy services, they are seeking to add a Consultant or Senior Sustainability Consultant to their team. They are a friendly, collaborative team that combines technical rigour with a pragmatic, commercially aware approach. As a small but ambitious consultancy, they offer meaningful responsibility, exposure to a wide range of projects, and genuine progression opportunities.
