About Us

We are a specialist, practitioner-led, consultancy who serve a variety of Public and Private sector organisations, across the UK’s District Energy industry.

We draw our expertise from over 15 years’ experience in designing, building, installing, operating and maintaining many of the UK’s largest city-centre district energy schemes.

We are at the very front of implementing change across our industry, in order to:

  • Enable honest and informed discussion about the risks and challenges Heat Networks face, as well as highlighting our positive practical experience of efficient and quality led schemes
  • Highlight the benefits associated with a greater level of information being developed in the pre-construction phase.
  • Promote CDM best practice, and the need for practitioner-led advice.
  • Increase awareness and management of complex, technical, commercial and buried risks in densely populated urban environments.
  • Reduce capital costs relating to buried infrastructure, leading to greater viability of district heating schemes, and their expansion.
