External expert review: HeatWise Home does not currently publish named external expert reviewers. We are working toward adding independent review from qualified retrofit, heating, or building-energy professionals. Until then, users should treat our calculators and guides as educational planning tools and confirm decisions with official sources and qualified installers.
Medium confidence
Energy prices, grant rules, and installation costs change frequently. The figures on this page are planning ranges, not quotes. Always confirm your current tariff, delivered fuel price, installer scope, and eligibility in the named references linked below.
Start with the numbers you can control
Irish homeowners often need to compare electricity prices, oil or gas costs, grant rules, fabric upgrades, and installer design before deciding whether a heat pump is sensible.
The pages in this section focus on practical planning. They do not promise grant eligibility or guaranteed savings, because prices and schemes can change.
Useful first steps
Use the heat pump cost calculator to test your current heating cost against a heat pump estimate. Then use the sizing and insulation pages to understand whether heat loss or attic insulation should be checked before final quotes.
If you use oil heating, pay close attention to your real oil delivery cost, boiler condition, and whether the oil tank needs maintenance or replacement.
