A Comprehensive Guide to Home Energy Assessment in Ireland

With your Home Energy Assessment completed, you now have a clear picture of where your home stands and what upgrades will make the biggest difference. The report doesn't just list recommendations—it prioritises them, so you know whether to start with insulation, a heat pump, or solar panels. This roadmap takes the guesswork out of your project and ensures every step you take moves you closer to a B2 rating or better. Because the HEA document is transferable, it empowers you to shop around and find the most competitive pricing across the OSS market.

Grant support for your HEA

If your home was built before 2011 and you have not claimed an HEA grant previously, SEAI offers grant support up to €350. This is applied as a deduction from the assessment cost. So you only pay the chosen One Stop Shop provider the net amount.

At Churchfield Home Services we explain how the Home Energy Assessment grant works at the start and what you will receive at the end of the assessment so you can plan with confidence.

Why Diligence and Clear Goals matter?

The HEA process is structured, but a structured process does not guarantee best value unless you stay involved. Homeowners who set clear goals, share priorities early and ask the right questions typically achieve better outcomes and stronger value for money. For that there are three areas deserve your attention:

✔ The B2 pathway

✔ The cost estimate

✔ Transferability

Churchfield helps you understand these early so you can make better decisions and avoid unnecessary costs later.

Understanding the B2 pathway 

There are multiple ways to reach a B2 or better BER rating. Your HEA usually presents one recommended pathway and shows progress step by step. So you can see how the BER changes with each measure. It is also useful to know that One Stop Shop supports depend on more than reaching B2. A minimum BER uplift of 100 kWh/m²/year is also required. How that looks can vary based on your home's conditions.

Because there can be different routes to the same destination, it is worth considering which option makes the most sense financially and in payback terms. For example, if your boiler was replaced recently, it may be better to prioritise other measures. If your heating system is old and inefficient, a heat pump can be a higher priority than adding solar PV. A sensible approach is to treat measures and costs beyond the B2 target and uplift requirement as optional so you are not forced into overspending to aim higher than you need to at the start.
