Its leadership team brings experience gained from major international consultancies, supporting the firm in maintaining consistently high standards of design and technical excellence. The company holds Low Carbon Consultant and Low Carbon Energy Assessor certifications and appears regularly among the top engineering consultancies in the UK. Most engineers within the practice are Chartered, and the company places strong emphasis on supporting those working toward professional accreditation.
