What is a Deep Retrofit?

A deep retrofit looks at the house as a whole and addresses all aspects of energy use in the home. The aim of a deep retrofit is to achieve a BER A-rating. To achieve this a number of areas need to upgraded together to increase the energy efficiency such as:

  • Wall insulation 
  • Attic
  • Replacing windows and doors. 
  • air tightness and 
  • Ventilation.
  • Providing a renewable energy resource  

The work involved is extensive and would be likened in scale to an extension.
