Top 5 Energy-Saving Upgrades After a Home Energy Assessment

Wall insulation

Walls account for a significant portion of heat loss in many Irish homes, particularly older properties.

A Home Energy Assessment helps determine whether cavity, internal or external wall insulation is most suitable. Improving wall insulation can dramatically reduce heat loss, stabilise indoor temperatures and improve comfort throughout the home.

This upgrade is often recommended alongside attic insulation to strengthen the overall performance of the building fabric.

Heating system upgrades

Once heat loss is addressed, attention often turns to how the home is heated.

Depending on the assessment findings, this may involve upgrading heating controls, improving system efficiency, or planning a transition to a more modern heating solution. The assessment ensures any heating upgrade is properly matched to the home’s insulation levels and layout.

Correct sequencing is important here — heating upgrades work best when the home is already retaining heat effectively.

Ventilation improvements

As homes become warmer and more airtight, ventilation becomes increasingly important.

A Home Energy Assessment considers airflow and ventilation to ensure good indoor air quality is maintained alongside energy improvements. In some homes, ventilation upgrades are recommended to help manage moisture, reduce condensation and support a healthier living environment.

This ensures energy efficiency improvements enhance comfort rather than create new issues.
