Free Irish Calculators & Decision Tools
Honest, no-sign-up tools for Irish homes and small businesses: grants, running costs, damp, resilience, payments and startup routes.
Irish rules, grants, tariffs and provider fees keep changing, while the useful answers are often scattered across official pages and sales sites. These free tools turn the current information into a practical result using your own inputs. There is no email, no login and no stored data.
