Home Energy Retrofit FAQs
A whole-house retrofit of a typical three-bed semi-detached house costs €35,000 to €55,000 before grants. This typically includes attic and wall insulation, window replacement, heat pump installation, MVHR ventilation, and associated electrics. Larger or older homes can cost €60,000 to €80,000. SEAI grants cover 50% of costs for most households and up to 80% for lower-income households, reducing your out-of-pocket cost to €10,000 to €30,000.
The One Stop Shop scheme provides a single SEAI-approved contractor to manage your entire retrofit from start to finish. They carry out the initial BER assessment, design the retrofit plan, coordinate all trades (insulation, windows, heating, ventilation), handle the SEAI grant application, and manage quality control. The grant is applied directly, so you only pay your contribution. This removes the complexity of managing multiple contractors yourself.
A deep retrofit typically brings a home from D, E, or F to B2 or better. The exact result depends on your starting point and the measures installed. Homes that start at G or F and receive full insulation, new windows, a heat pump, and MVHR often reach B1 or even A3. Your One Stop Shop should provide a target BER rating as part of their proposal, calculated using DEAP software.
A typical whole-house retrofit takes 4 to 8 weeks from start to finish. External wall insulation takes 2 to 4 weeks. Window replacement takes 2 to 5 days. Heat pump installation takes 2 to 4 days. MVHR installation takes 2 to 3 days. These phases may overlap. Add 4 to 8 weeks for grant approval before work can begin, so the total timeline from initial enquiry to completion is typically 3 to 5 months.
Yes. Older homes (pre-1980) benefit most from retrofit because they start from a much lower baseline. A home rated F or G that achieves B2 after retrofit can see heating bills drop by 50 to 70%. The property value increase (typically 10-15% based on ESRI research) often exceeds the homeowner's share of the cost after grants. The improved comfort, reduced noise, and better air quality are additional benefits that homeowners consistently rate as the most noticeable improvement.
Not necessarily, but it depends on the scope. External insulation, roof work, and window replacement can usually be done while you live in the house, though there will be noise and scaffolding. Internal dry-lining means losing access to rooms one at a time. Heating system replacement means a day or two without heating. Some homeowners choose to stay elsewhere for the most disruptive phase (usually 1 to 2 weeks), while others manage with some inconvenience. Your One Stop Shop should advise on the best approach.
