Common questions about retrofitting in Wexford
What SEAI grants are available in Co. Wexford?
All SEAI Better Energy Homes grants are available nationwide including Co. Wexford. This includes grants for insulation (up to €6,000), heat pumps (up to €6,500), solar panels (up to €1,800), windows (up to €4,000), and heating controls (€700). You must use an SEAI-registered contractor.
How much does a home retrofit cost in Wexford?
A typical retrofit in Wexford costs €5,000–€25,000 depending on the upgrades chosen. Attic insulation is the cheapest (€800–€2,500 before grant). A full deep retrofit with insulation, heat pump and solar can cost €30,000–€50,000 before grants. SEAI grants typically cover 30–50% of the total cost.
How do I find SEAI-registered contractors in Wexford?
RetrofitReady lists SEAI-registered contractors covering Co. Wexford with phone, WhatsApp and website links so you can contact them directly. We recommend getting at least 3 quotes. Browse contractors at retrofitready.ie/contractors/wexford.
Do I need a BER assessment in Wexford?
Yes, for most SEAI grants you need a BER assessment before and after the work. A BER assessment costs around €150–€200 and SEAI contributes €50. The assessor rates your home from A (most efficient) to G (least efficient) and identifies the best upgrades for your property.
Can I get solar panels without doing a full retrofit?
Yes. Solar panels are available as a completely standalone SEAI grant. You do not need insulation, a heat pump or any other work done first. Find an SEAI-registered solar installer, apply for grant approval before work starts, and have the panels installed. The grant is up to €1,800.
What is a One Stop Shop retrofit?
A One Stop Shop is a single contractor who manages your entire retrofit — from survey to SEAI application to project completion. They coordinate all the trades (insulation, plumbing, electrical) so you only deal with one company. This is ideal for larger projects involving multiple upgrades.
