Our Ecological Clerk of Works are currently supporting ongoing investigation works required to inform the design and DCO submission in late 2026. The need for ecological supervision is however increasing as the project evolves and we are looking to expand our team of dedicated Ecological Clerk of Works to play a key role in ensuring ecological compliance and best practice on site.
While SESRO will be your primary focus, you'll also become a valued member of our national ecology and environmental team, with opportunities to contribute to other major infrastructure projects in the future. You can also join our active Ecological and Environmental Clerk of Works Communities of Practice.
If not already a full /chartered member of CIEEM we can provide mentoring. You will also benefit from technical, and H&S training and paid membership of two professional institutions.
Binnies is a registered Ecological (CIEEM) and Landscape Practice (Landscape Institute) and holds the IEMA (now ISEP) EIA Quality Mark. We also sponsor AECOW reflecting our commitment to promoting site based environmental roles.
