Alec Sims joins Granlund UK as a Senior Consultant, bringing expertise across the energy transition, heat networks, portfolio decarbonisation, and sustainability.

David has a background in Mechanical Building Services design and contracting. He has been involved in District Heating since 2010, with roles in city energy master planning, district heating business development within the private sector, and as a client engineer for public sector funders of district heating projects.
