Despite grant supports, retrofits continue to cost in the tens of thousands of euros.

Despite the recent increase in energy upgrade grant amounts, a whole house energy upgrade continues to require an out-of-pocket investment of tens of thousands of euros.
The head of one of Ireland’s largest house builders recently said it could cost up to €70,000 to retrofit a second hand home up to the A building energy rating standard that is required for new builds.
Four years ago, experts estimated the average retrofit costs were half that amount.
