Helping you navigate SEAI grants
30 June 2025
Making your home warmer, greener, and cheaper to run is easier than you think.
The Sustainable Energy Authority of Ireland (SEAI) offers a range of grants to help you improve your home’s energy efficiency. From attic insulation to solar panels and heat pumps, there’s support available for every type of upgrade. This guilde will help you understand the different grants and how to apply.
The Sustainable Energy Authority of Ireland (SEAI) offer a variety of home energy grants to help Irish households upgrade their homes with energy efficient solutions. Retrofitting works not only make your house more comfortable but can also increase your homes energy efficiency, in turn reducing your energy costs and carbon emissions. This article will help you understand the home energy grant options offered by the SEAI. There are a number of ways to plan and manage your home energy upgrade and grant applications. To manage their own project To apply for the grant themselves To pay for full cost of works and claim grants afterwards One-stop shop grants are a complete home energy upgrade solution for homeowners who want to carry out multiple energy upgrades and who wish to have the entire upgrade process managed for them. Individual energy upgrade grants include the following grant options: Attic insulation is often the most cost effective upgrade you can make to your home. Professionals recommend checking what insulation lies between the ceiling joists in your attic – it should be between 300mm and 400mm. In older homes, insulation is usually non-existent or is about 100mm in depth. Insulating the attic is like putting on a hat. Heat rises, so you will see an immediate benefit from this work.

They are designed to meet about 50 to 60 percent of your overall annual hot water requirements. Installing a heat pump can transform the comfort levels in your home whilst reducing energy costs. Heat pumps are far more efficient than traditional heating systems with Air to water heat pumps being the most common in Ireland.

PV or Photovoltaics is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect. Solar PV energy will help to substantially reduce your energy needs and in turn electricity bills. Having your own installed solar energy system will significantly improve the energy efficiency of your home and deliver a significantly improved BER Rating.

What types of home energy upgrade grants are available?
Individual energy upgrade grants are the solution for homeowners who want to manage the upgrade process themselves. This option offers a selection of individual grants for home energy upgrades which are part funded with SEAI grants, up to 80% of the cost of the upgrade for a typical family home. These grants are suitable for homeowners who want:

€1,500
Looking at the approximate costs associated with attic insulation, Professionals have said that, attic insulation costs can be in or around €3,000 and the grant available for a standard semi-detached family home is €1,300, so the cost for you will be in or around €1,700. When you take into consideration the potential savings to your annual energy bill of 10-15%.Wall insulation grants

Cavity Wall Insulation Grant
Cavity walls are injected from the outside with insulation.

€1,200
€1,700
Internal Insulation Grant (Dry Lining)
Insulation boards are fixed to the inside of external walls.
€4,500
External Wall Insulation Grant (External wrap)
Insulating materials are fixed to the outer surface of external walls.
Looking at the approximate costs associated with wall insulation, Professionals have said thatProfessionals have said that, upgrading internal dry lining can be an expensive process and can vary in price starting anywhere from €15,000 up to €20,000. The process requires adjustments to any power sockets, switches or decorations on the internal walls. It’s worth noting that in some cases, new floor finishes may also be required.
Adding external wall insulation is a very effective but can often be the most expensive option, ranging from €30,000 to €45,000. This covers the adjustment of downpipes and new lightweight windowsills.
To insulate under the ground floor of your home, including adding a new concrete slab, insulation, and membrane, typically costs somewhere in the region of €20,000 to €25,000. Lifting the floorboards and insulating between floor joists is a more affordable option, costing in the region of €12,000 to €15,000. Costs and decisions are all dependent on the ground floor area.Grants for solar water heating systems

Grants for solar electricity (PV) systems
Grant name | Value | Example |
---|---|---|
Solar PV grant | €700 per kWp up to 2kWp | €1400 for 2kWp solar panels |
€200 for every additional kWp up to 4kWp Total Solar PV grant capped at €1800 |
€1600 for 3kWp solar panels €1800 for 4kWp solar panels |
* Solar PV grants are capped at €1,800 per household
Considerations when assessing Solar Electricity (PV) options:
Generally, you will not need to seek planning permission for solar panels that take up less than 50% of the total area of your roof (this approximately equates to a 6-panel system). You should consult with your local authority for guidance about planning permission if:
- Your proposed solar system is larger than 6 panels or 2kW
- Your home is a protected structure
- Your home is located in a protected area, for example, an architectural conservation area
Grants for heating controls
Heating controls are a great option to help control your heating and hot water needs to the way you use your home. There are different benefits to upgrading your heating control including reduced energy usage which will save you money on energy bills in the long run. Heating controls help you to heat your home only when you need to and upgraded heating controls are usually zoned within the home for more efficiency. With heating controls, you will be able to heat your water without having to turn on your home heating. If you live in a two-storey dwelling, you can isolate your upstairs and downstairs into two distinct heating zones to further extend your energy efficiency.

Heat pump grants
Heat pumps are renewable heating systems offering lower energy costs and reduced carbon emissions. They harness the energy from the air, water or ground outside your home, heating the building and hot water. This heating system is an alternative to the regular fossil fuel system.
In order to qualify for a SEAI heat pump grant, a technical assessment must be carried out in your home prior to works being carried out. This must be done by an SEAI registered Technical Advisory. Heat pumps work better in homes that are very well insulated with double or triple glazed windows. This is to make sure your heat pump is working at the optimal level and your electricity bills will be low.
