The Sustainable Energy Authority of Ireland (SEAI) offers different grants to help homeowners improve energy efficiency and reduce heating costs. Many people in Ireland want to know if they can get a grant to replace their gas boiler. This article explains the latest information for 2026 in simple English.
Can You Get a Grant to Replace a Gas Boiler?
In 2026, the answer is simple:
SEAI does NOT give grants for replacing gas boilers alone.
If you want to remove your old gas boiler and install a new gas boiler, SEAI grants will not pay for it. This is because gas boilers use fossil fuels, and Ireland is trying to reduce carbon emissions and move towards cleaner energy.
Instead of supporting fossil fuel systems, the government now focuses on energy-efficient and renewable heating solutions.
Why SEAI Does Not Support Gas Boilers
Ireland has a goal to reduce carbon emissions and protect the environment. Gas and oil boilers produce carbon dioxide, which harms the climate.
Because of this, SEAI encourages homeowners to:
- Use renewable energy
- Improve insulation
- Install modern heating systems like heat pumps
This approach helps reduce energy bills and makes homes more comfortable in the long term.
What Grants Are Available Instead?
Even though you cannot get a grant for gas boiler replacement alone, SEAI offers several other useful grants.
1. Heating Controls Grant (€700)
You can get around €700 to upgrade your heating controls.
This includes:
- Smart thermostats
- Zoned heating systems
- Better timers and controls
These upgrades help you use less energy and save money.
2. Heat Pump Grants (Up to €12,500)
Instead of a gas boiler, SEAI strongly supports switching to a heat pump system.
You can get:
- Up to €6,500 for the heat pump
- Up to €2,000 for heating system upgrades
- €4,000 bonus for replacing a gas or oil boiler
Total support can reach €12,500.
Heat pumps use electricity and renewable energy, making them much more efficient than gas boilers.
3. Insulation Grants
Before changing your heating system, SEAI recommends improving insulation.
Grants are available for:
- Attic insulation
- Wall insulation
- Windows and doors
These upgrades help keep heat inside your home and reduce energy waste.
4. Solar Energy Grants
You can also install solar panels to reduce electricity costs.
SEAI offers support for:
- Solar PV panels
- Solar water heating systems
This is a great way to combine renewable heating with clean electricity.
5. Fully Funded Upgrades (Warmer Homes Scheme)
If you receive certain social welfare payments, you may qualify for free home energy upgrades.
This scheme may include:
- Insulation
- Heating improvements
- Renewable systems
However, gas boilers are not included in this scheme.
Who Can Apply for SEAI Grants?
Most SEAI grants are available to:
- Homeowners
- Landlords
- Properties built before 2011 (in most cases)
For some schemes, your home must:
- Have a low energy rating (BER)
- Be upgraded to a better rating after work
One Stop Shop Scheme
SEAI also offers a One Stop Shop service. This is a complete upgrade package.
With this option:
- Experts manage your project
- Grants are deducted from the total cost
- Your home is upgraded to a high energy rating
This is useful if you want to upgrade your entire home instead of just one system.
Should You Replace Your Gas Boiler?
If your gas boiler is old, you have two main choices:
Option 1: Replace with Another Gas Boiler
- No SEAI grant
- Lower upfront cost
- Still uses fossil fuel
Option 2: Upgrade to a Heat Pump
- Large SEAI grant available
- Lower energy bills over time
- Environmentally friendly
Most experts recommend moving to a heat pump instead of installing another gas boiler.
Benefits of Switching from Gas to Renewable Heating
Replacing your gas boiler with a modern system can offer many benefits:
1. Lower Energy Bills
Heat pumps are very efficient and use less energy.
2. Better Comfort
Your home stays warm for longer periods.
3. Higher Property Value
