Many older residences in Killiney (Dramatic hillside Victorian and Edwardian villas, coastal granite properties along Killiney Hill Road and Victoria Road, and substantial 1970s executive residences.) carry D, E, or F Building Energy Ratings. A deep retrofit elevates these homes to a comfortable B2 or A2 rating, reducing heating energy requirements by 60% to 80%.
Homeowners in Killiney can choose between two SEAI grant pathways:
| Measure | Detached Grant | Semi-Detached Grant | Mid-Terrace Grant |

| Heat Pump (Air-to-Water) | €6,500 | €6,500 | €6,500 |

A comprehensive whole-house deep retrofit in Killiney typically costs between €60,000 and €110,000 gross. With SEAI grants offsetting €25,000 to €38,000+, the net homeowner cost usually ranges from €35,000 to €75,000.
Deep retrofit projects under the SEAI One Stop Shop program are designed to elevate your home to a minimum of B2, with the vast majority achieving an A2 or A3 Building Energy Rating.
A whole-house deep retrofit typically takes 8 to 14 weeks from initial scaffolding to final BER certification and commissioning of the heat pump and ventilation systems.
