The external insulation grant for an end of terrace
An end-of-terrace house gets a fixed €6,000 from SEAI for external wall insulation. The typical one has about 85 m² of outside wall, and a typical job for that wall costs about €23,200, so about €17,200 is left to pay. That's about €70 of grant for every square metre.
The semi-D grant, a gable to wrap, and what's left.
Free, no obligation. One registered contractor prices it, not five.

Your grant against your walls
Four quick taps. You see your grant, your wall, what a job that size typically costs and what's left. Your number is only asked for at the end, if you want a price.
An average semi-detached house: about 91 m² of outside wall, a typical job of about €23,200, the €6,000 grant, so about €17,200 left to pay.
How this is worked out
The grant is SEAI's fixed amount for your house type. The wall area is the median outside wall on the BER register for homes of your type built before 2011, or the smaller or larger quarter if you picked those. The typical job is what grant-funded external insulation typically costs for your house type, scaled to that wall. Your contractor prices your house after a look: it's a guide to plan with, never a quote. SEAI decides every grant.
The gable end
SEAI gives an end of terrace the semi-D grant, €6,000. It usually has a little less wall than a semi-D, about 85 m² against 91 m², and one long gable with few openings, the simplest wall of the job.
