What the median does not tell you
- SEAI’s apartment median (€4,646) is the highest of the four dwelling types and sits well above the detached figure (€3,500). Apartment heating systems are frequently harder to zone and to route cabling through.
- The €700 grant is flat across every dwelling type, so it covers a fifth of a typical apartment job and a fifth of a typical detached one.
