What is a retrofit assessment?
A retrofit assessment is a detailed survey of your home: its construction, condition, heating, ventilation and energy performance. It identifies the most effective improvements and the right order to make them, so upgrades work together rather than causing problems like damp or poor ventilation. The assessment underpins a whole-house retrofit plan carried out to PAS 2035, the recognised industry standard.
