What this site is

Ireland's retrofit conversation is split between SEAI's official grant pages (accurate but bureaucratic), contractor sites (accurate about their services, biased toward sale), and forum threads (honest but unstructured). This site sits in the middle: plain-English, current numbers, named contractors, no contractor up-sell.
