Applying for the SEAI heat pump grant? Your home has to pass a Technical Assessment first — and it has to be carried out by an SEAI-registered Technical Advisor before any work starts.
The assessment measures your home’s Heat Loss Indicator (HLI). To qualify for the grant, that figure has to come in at 2.3 W/(K.m²) or below. It applies to homes built before 2007, unless you already hold a valid BER showing the heat loss is low enough.
Tom Murray is an SEAI-registered Technical Advisor working across Cork city and county. Site survey, HLI calculation, signed Technical Assessment Form — plus a clear list of the upgrades needed if your home doesn’t pass first time.
A Technical Assessment is a survey of how much heat your home loses through its walls, roof, floors, windows and doors. That total, divided by your floor area, is the Heat Loss Indicator — the HLI.
A heat pump only runs efficiently in a home that holds its heat. That is why SEAI will not pay the grant until an assessment shows your HLI is 2.3 W/(K.m²) or below.
It is not a pass-or-fail dead end. If your home comes in above the threshold, the report sets out which upgrades would bring it under, what each is likely to cost, and the HLI you should expect afterwards.
You need one if:
Homes built from 2007 onward do not always need one — a valid BER showing acceptable heat loss can be enough. Send us the address and we will tell you which applies.
Who needs an assessment, what happens on the day, and what to do if your home does not pass first time. Most of it comes down to one number and the paperwork behind it, get both right and the grant application is straightforward rather than a delay on your install.
You need a Technical Assessment if you are applying for the SEAI heat pump grant and your home was built before 2007.
The assessment has to be done before the work starts. SEAI will not pay for it retrospectively.
Without documentation for insulation already done, the software has to assume the worst — which is the single most common reason a home scores worse than the owner expects.
The Heat Loss Indicator is your home’s total heat loss divided by its floor area, measured in W/(K.m²).
Coming in above 2.3 is not the end of it. Most homes that fail need one or two fabric measures, not a full retrofit.
SEAI supports the assessment itself, not just the heat pump.
We look after the assessment and the post-works BER. Your installer looks after the heat pump and the grant application itself.















If your home was built before 2007, yes — unless you already hold a valid BER showing the heat loss is low enough. It has to be done before the work starts.
2.3 W/(K.m²) or below. Some older articles still quote 2.0 — 2.3 is the current SEAI threshold.
The report lists the upgrades that would bring you under the threshold, with costs and the HLI you should expect afterwards. Most homes need one or two fabric measures, not a full retrofit.
No. A BER rates energy performance A to G. The Technical Assessment uses the same survey to answer a different question: is the heat loss low enough for a heat pump to work well. A BER is usually published as part of it. If you only need a rating, see our BER assessments in Cork City.
The survey itself takes a couple of hours for a typical house, and the report follows shortly after. Working to an installer’s start date? Tell us and we will prioritise it.
Someone needs to give access to the whole house, including the attic and any plant or meter locations, along with documentation for insulation work already carried out.
