Upgrading an Irish home: which question to answer first

These four tools answer parts of one decision, and the order is not a preference. SEAI describes a fabric-first approach, and for many homes the heat-pump route runs through a technical assessment that says what fabric work the house needs before the grant application. That makes the insulation question a precondition rather than a parallel option. No answers are passed between pages or stored.

Answer the one the others depend on first

None of these four decisions expires, and that is exactly why the order gets skipped. It still matters: depending on when a home was built and what its BER heat-loss indicator shows, the heat-pump grant route can run through a technical assessment, and that assessment is what says which fabric work the house needs. For those homes insulation is a precondition of the heating decision, not an alternative to it. Generation is last, because what a self-consumed unit is worth depends on how many units the house still needs.

  1. Where does the house stand before anything is spent?

    First, because every later answer depends on how the house performs now. It is still the softest of the four answers: it uses the current A-G thresholds and official CSO stock averages as calibration anchors, but it is not a DEAP 4.3 assessment, so treat it as a screening indication. Its real value here is telling you whether booking an assessor is worth it, because a valid BER is also what step three reads when it decides whether a technical assessment is needed, so the certificate may do more than one job.

    You will need: When the home was built, what kind of home it is, its floor area, the main heating system, the insulation and glazing it has now, and any solar.

  2. Which fabric measures are grant-funded, and what would they cost?

    Second, because fabric comes before heating. Individual insulation grants have their own dwelling-age condition, and SEAI's second-wall sequencing rule decides which wall measures are still open, depending on what has already been claimed.

    You will need: When the home was built and first occupied, whether you own it, the house type, and the measures already done.

  3. Is the home ready for a heat pump, and does insulation come first?

    Third, and it is the step that reorders the two before it. When the home was built and whether a valid BER shows a passing heat-loss indicator decide whether the technical assessment comes first, and that assessment is what says which fabric work the house needs. The heat pump checker tells you which side of that gate your home is on, and what it costs to pass through it.

    You will need: When the home was built, whether a valid BER shows a heat-loss indicator at or below the threshold, the heating fuel now, and the heat-pump type being quoted.

  4. Does generation pay once demand has come down?

    Last, because the value of a kilowatt-hour you generate depends on how many the house still needs and when it needs them. Sizing an array against a pre-upgrade bill oversizes it. The solar grant has its own dwelling-age condition, separate from the other two.

    You will need: When the home was built and first occupied, the proposed array size and orientation, your import and export rates, and any quoted cost.

The rules that set the order

Six facts that decide which question comes first

Fabric first
The order SEAI describes for a home energy upgrade
Seal the house before sizing the heating system: a heat pump's efficiency is a property of the fabric it is heating.
Home age and BER
What decides whether the technical assessment applies
SEAI draws a build-date line for the pre-application assessment, and a valid BER with a passing heat-loss indicator also counts. This is the fact that decides whether insulation is a precondition or a parallel choice, and the heat pump checker says which side your home is on.
Heat-loss indicator
What a valid BER has to pass for the self-declaration route
Printed on the BER certificate. Whether it is at or under SEAI's threshold decides whether an older home can self-declare instead of having the assessment. The heat pump checker tests your BER against it.
Three build-date cut-offs
One each for the insulation, heat-pump and solar grants
They do not match, so a home can be inside one scheme and outside another, and which of the three it can take changes what the first useful step is. Each checker asks with its own scheme's date and says whether your home is inside it.
Second wall measure
Which wall grant can follow another
SEAI's sequencing rule decides whether a home that has already had a wall grant can have another, and which. The insulation checker works it out from the work already done, by you or a previous owner.
Technical assessment
A paid assessment before applying
Paid before the heat-pump grant application, and the report is what lists the fabric work required. The heat pump checker gives the fee.
