Suggested solution

Build an insulation company whose own crews insulate the whole house at one fixed price and handle the subsidy, as 3 companies already do in Germany.

  1. A roof-and-loft installer. Today: Surveys and quotes the roof and loft. With the suggested solution: One firm quotes the whole house at one price.
  2. A facade firm. Today: Surveys and quotes the facade separately. With the suggested solution: no longer needed.
  3. A paid subsidy desk. Today: Does the energy assessment and subsidy application. With the suggested solution: The same firm handles it, inside its price.
  4. The installers' crews. Today: Each insulates only its own part. With the suggested solution: One set of crews insulates roof, loft and walls.

Execution difficulty

1/3 · Hard

Makes it easier

  • Homeowners sign directly.
  • No licence is needed.
  • The state subsidy already co-pays the work.

Makes it harder

  • Trained crews in the field, blowing equipment and in-house subsidy handling are paid for before the first fixed-price job.
  • A national installer has insulated roofs and lofts with its own crews since 1997.
