Send us your plans by email or post and we can make an analysis of your project and design up holistic eco-solutions.

This type and deep level of service is not available anywhere else, on or off line. Many providers give overview heat losses and specify systems, but often the view is not holistic and focused on one type of product. We look at the whole building and lifestyle of occupants and provide a holistic solution.

Results of assessment include:

  • Predicted heat loss of building (so you know what heat loses you need to deal with).
  • This is specific to your 'degree day' region. i.e. where you live in the country.
  • Takes into account number and age of people living in your home.
  • Predicted running costs, now and after upgrades are undertaken.
  • We produce a raft of solutions to suit your budget and lifestyle and trim the solution to your needs.
