Your First Step to a Warmer, Greener, More Efficient Home – One Upgrade at a Time
If you’re not ready for a full deep retrofit but want to make your home more energy efficient, the SEAI Better Energy Homes (BEH) scheme is a great place to start. This government backed grant supports individual upgrades such as insulation, heating controls, heat pumps and solar, and now includes a grant for windows and doors, helping you cut energy bills and live more comfortably
Retrofit Design will guide you through the entire process – from helping you choose the best energy upgrades and securing the maximum SEAI grant funding, to completing the works to the highest standard.
What is the SEAI Better Energy Homes (BEH) Grant?
Grants offered are provided by the Government of Ireland through the Sustainable Energy Authority of Ireland (SEAI)
The BEH scheme is designed for homeowners and landlords who want to improve their home’s energy efficiency with individual retrofit measures, rather than a full deep retrofit.
The Hassle-Free Way to Access Your SEAI Grants
You can apply for these grants yourself via SEAI, or work with an SEAI registered One Stop Shop (like Retrofit Design) who can:
- Apply for the grant on your behalf
- Deduct the grant value directly from your costs
- Manage the entire project for a stress free experience
What’s Covered by the BEH Grant?
The BEH scheme offers funding for the following energy saving upgrades:
- Wall insulation (internal, external, or cavity)
- Attic insulation
- Windows and doors
- Heat pump systems
- Heating Controls
- Solar PV installation
- Solar water heating (thermal)
- Post works BER assessment
What's Not Covered by the BEH Grant
- Full home retrofits (BEH supports individual upgrades only)
- Non-energy-related home improvements
- Repeat claims for the same measures at the same address
- Homes built after 2011 (for insulation/heating controls) or after 2021 (for renewables)
For these upgrades or a full retrofit, consider the SEAI One Stop Shop (OSS) grant instead – Click Here to Learn More
Am I eligible?
You can apply if:
- You own the home (homeowner, landlord, Approved Housing Body, charity, or company)
- Your property was built before 2011 (for insulation & heating controls) or 2021 (for renewable systems like heat pumps or solar)
- You have a valid MPRN number (on your electricity bill)
- You haven’t already claimed a grant for the same measure at this property (Homeowners who have previously availed of a grant for cavity or internal wall insulation, can now apply for a second wall insulation measure.)
- For heat pumps: Homes built before 2007 may require a technical assessment; newer homes can self declare

Can BEH Grant Be Combined With Other Grants?
Yes – in some cases, you can combine the Better Energy Homes (BEH) grant with other supports to maximise your funding. For example:
- If your home is vacant or derelict, you may first claim the Vacant Property Refurbishment Scheme to make it habitable.
- You can then apply for BEH grants for individual energy upgrades like insulation or heating controls.
- Alternatively, you might start with BEH measures and later progress to a full deep retrofit using the SEAI One Stop Shop (OSS) grant.
We’ll guide you through the best sequence for your situation, so you don’t miss out on any available funding.
One Stop Shop Benefits
Project Management
Retrofit Design will project manage the full process for the homeowner from the initial stage of your enquiry, through to arranging the home energy assessment, the installation, and leaving the homeowner to focus on the benefits.
SEAI Grants
Homeowners can avail of the substantial grants available through SEAI to cover a proportion of the cost of the energy upgrade. Grant funding will ensure our customer maximises the funds available.
Lower Energy Bills
Homeowners can enjoy lower energy bills because they have, for example, invested in better insulation, new windows and doors, and efficient heating systems. Homeowners enjoy savings of hundreds each year on heating and electricity.
Enhanced Property Value
Homes with a higher Building Energy Rating (BER) are more appealing to buyers and they often command a higher market value. An OSS upgrade ca be recognised as an investment into the homes overall value.
