Big changes are coming to home energy upgrades and insulation grants in Ireland. For homeowners across Dublin and the surrounding areas, there has never been a better time to upgrade your attic insulation.
Under the Government’s new National Residential Retrofit Plan 2026, SEAI has announced higher grants, wider eligibility, and new supports designed to make homes warmer, cheaper to heat, and more energy efficient. These changes directly benefit homeowners, landlords, first-time buyers, and households on qualifying welfare payments, with attic insulation and wall insulation playing a central role.
At Lovinsulation, we’re SEAI-registered insulation specialists with over 3,000 projects completed across Dublin. Here’s what the new SEAI grant changes mean for you, and how we can help you make the most of them!
Higher SEAI grants for attic & cavity wall insulation
From 3rd February 2026, SEAI will increase grant amounts for attic insulation and cavity wall insulation under the Better Energy Homes Scheme.
These higher fixed grants recognise that material and labour costs have risen in recent years and are designed to substantially reduce the upfront cost for homeowners who want to improve comfort and cut heating bills.
For many Dublin homes, attic insulation remains the most cost-effective energy upgrade available, delivering:
- Reduced heat loss
- Lower energy bills (often up to 30%)
- Improved comfort all year round
- Better BER ratings
With higher grants now available, upgrading your attic insulation can cost far less than many homeowners expect.
New attic insulation grants for first-time buyers
From 2nd March 2026, first-time buyers of existing homes will benefit from a new, enhanced attic insulation grant.
This is a major change. Many first-time buyers move into older properties that lose heat quickly but don’t have the budget for a full deep retrofit. SEAI’s new approach allows them to:
- Start their energy upgrade journey immediately
- Avail of higher fixed grants specifically for attic insulation
- In many cases, some have most or all of the insulation cost covered
If you’ve recently bought an older home, attic insulation is now one of the easiest and most affordable upgrades you can make, especially when installed correctly by an experienced attic insulation provider.
Increased support for households on qualifying welfare payments
SEAI has also announced higher fixed grants for attic and cavity wall insulation for homeowners on qualifying welfare payments, aligned with the Warmer Homes Scheme eligibility.
From 2nd March 2026, these homeowners can access:
- Higher grant amounts that often cover most or all of the total cost
- Faster access to essential insulation upgrades
- Improved warmth, comfort, and reduced energy poverty
Importantly, availing of these grants will not affect your place on the Warmer Homes Scheme waiting list for other measures.
We regularly work with homeowners who need clear guidance through SEAI grants, and we can help you understand which supports you’re eligible for.
Grants now encourage phased upgrades, not just deep retrofits
A key shift in SEAI’s new retrofit plan is the flexibility it offers.
Homeowners are no longer pushed toward completing everything at once. Instead, SEAI is encouraging phased upgrades, starting with building fabric improvements such as:
- Attic insulation
- Wall insulation
- Draught proofing
These measures make homes warmer immediately and prepare them for future upgrades like heat pumps or high-performance windows.
For many Dublin homes, getting attic insulation right is the foundation for long-term energy efficiency.
Why attic insulation is the smart first step
Attics are one of the largest sources of heat loss in Irish homes. Poor or outdated insulation leads to:
- Cold rooms upstairs
- Higher heating bills
- Uneven temperatures
- Increased risk of condensation and damp
At Lovinsulation, we install attic insulation using industry-leading methods to ensure airtightness, correct ventilation, and long-term performance.
With SEAI grants now increased, attic insulation delivers one of the fastest returns on investment of any home upgrade.
