Top 5 Energy-Saving Upgrades After a Home Energy Assessment

A Home Energy Assessment gives you a clear understanding of how your home performs today and where energy is being lost. Rather than guessing which upgrades might help, the assessment highlights what will make the biggest difference for your home and in what order. At Churchfield Home Services, homeowners often ask what comes next after an assessment. While every home is different, these are the five energy-saving upgrades most commonly identified once a full picture of the home is understood.

Attic insulation


Attic insulation is often one of the first upgrades recommended after a Home Energy Assessment.

Heat naturally rises, and an under-insulated attic allows a large amount of warmth to escape. Improving attic insulation helps keep heat inside the home for longer, making rooms more comfortable and reducing the energy needed to maintain a steady temperature.

Because it delivers noticeable improvements quickly and with minimal disruption, attic insulation is a common early step in many upgrade plans.
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.

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.

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.

Solar PV


For some homes, generating electricity on site can further improve overall energy performance.

Solar PV may be recommended where roof orientation, household energy use and suitability align. When installed as part of a planned upgrade journey, it can help reduce reliance on grid electricity and complement other energy-saving measures already in place.

Home Energy Assessment helps confirm whether solar PV makes sense for the home and how it fits into the wider plan.

Bringing it all together


Home Energy Assessment helps bring these upgrades together into one clear, practical plan. Instead of treating each improvement in isolation, it looks at how your home works as a whole and what will deliver the best long-term results.

With the right information from the start, you can move forward with confidence, knowing each upgrade is suited to your home and completed in the right order.
