External Wall Insulation (EWI) systems are widely used to improve the thermal performance, durability, and energy efficiency of residential buildings.
Many systems installed across housing estates and public sector buildings were delivered as part of energy efficiency and regeneration programmes over the past 15–20 years.
While these systems can deliver long-term performance benefits, they also require ongoing inspection and maintenance to ensure they continue to perform as intended.

EWI Health Check supports housing providers and estate managers in implementing structured inspection and maintenance strategies for External Wall Insulation systems.
Through condition surveys, façade investigations and planned maintenance programmes, we help ensure EWI systems continue to perform effectively throughout their intended lifespan.
