Top 5 Energy Upgrade Grants in Ireland 2026

If you are a homeowner in Ireland looking to cut your heating bills and reduce your carbon footprint, you need to know about the energy upgrade grants Ireland 2026 landscape. Right so, the government has rolled out a fresh wave of supports that make it easier and cheaper to upgrade your home. To be honest, the whole process can feel a bit overwhelming at first, but once you dig in it is grand. I remember when I first looked into insulating my own gaff I got lost in the jargon. Fair enough, the schemes have improved a lot since then. Anyway, here is a rundown of the five best grants you can apply for right now. Look, before we get into the nitty gritty, remember that you can browse properties that have already been upgraded on Findivo's property listings to see what is possible.

1. The National Home Energy Upgrade Scheme (One Stop Shop)

This is the big one. The National Home Energy Upgrade Scheme offers grants for a whole house retrofit. The idea is you go through a registered One Stop Shop provider who manages the entire project from start to finish. The CSO reported that average energy costs in older homes are nearly 40% higher than in modern ones, so this grant really targets the worst performing homes. You can get up to 50% of the cost covered, depending on the measures you choose. The energy upgrade grants Ireland 2026 under this scheme are designed to push your home to a B2 BER rating or better. If you are serious about slashing your bills, this is the gold standard.

What it covers

• Attic insulation and cavity wall insulation
• External or internal wall insulation
• High efficiency heat pumps (air to water or ground source)
• Solar panels for hot water and electricity
• Heating controls and ventilation systems

One tip: you need to get a BER assessment done before you start. The assessor will tell you exactly what upgrades will make the biggest difference. It costs a few hundred euro, but it is worth it to get the full grant amount.

2. The Better Energy Homes Scheme (Individual Measures)

Not everyone wants or needs a whole home retrofit. Maybe you just want to slap some attic insulation in and be done with it. That is fair enough. The Better Energy Homes Scheme lets you pick individual measures and get a fixed grant for each one. For example, attic insulation gets you around 1,200 euro, depending on the house size. Wall insulation is more. This is a great way to chip away at your home's energy performance without a huge upfront cost. According to the RTB, landlords are increasingly required to meet minimum BER standards for rental properties, so if you are a landlord this energy upgrade grant Ireland 2026 option can help you stay compliant. Anyway, the grant amounts are standard and you can apply online through the SEAI.

Individual measures and typical grants

• Attic insulation: up to 1,200 euro
• Cavity wall insulation: up to 1,700 euro
• Internal or external wall insulation: up to 4,500 euro (per wall)
• Heat pump system: up to 3,500 euro
• Solar water heating: up to 1,200 euro

Practical tip: Always get at least three quotes from registered contractors before you apply for an individual measure grant. The SEAI requires that the work is carried out by a registered professional, but prices can vary wildly. I saved nearly 800 euro on my attic insulation by shopping around.

3. The Warmer Homes Scheme (Free Energy Upgrades)

If you are on a low income or in receipt of certain social welfare payments, you might qualify for the Warmer Homes Scheme. This is a fully grant funded program that covers the full cost of energy upgrades. To be honest, it is the best deal in town. You do not pay a cent. The scheme is managed by the SEAI and focuses on homes that are owner occupied and built before 2006. Look, the waiting list can be long, but it is worth applying. The energy upgrade grants Ireland 2026 include this scheme, and the budget was increased this year to clear the backlog. The works typically include attic insulation, cavity wall insulation, draught proofing, and sometimes a new heating system if needed.

Eligibility criteria

You must be the owner and living in the house. Your household income must be below a certain threshold, or you must be in receipt of a qualifying payment like Fuel Allowance or Jobseeker's Allowance. The CSO data shows that households at risk of poverty spend a much larger share of their income on energy, so this grant is designed to target exactly those homes.

4. The Community Energy Grant Scheme (For Neighbourhoods)

This one is a bit different. Instead of applying as an individual, you get together with your neighbours and apply as a community. The grant covers a range of energy upgrades for multiple homes in a defined area. It is grand if you live in an estate or a row of similar houses. The idea is to bulk buy materials and share a contractor, which brings down costs for everyone. The energy upgrade grants Ireland 2026 under this scheme can cover up to 80% of the cost for community buildings and up to 50% for homes. I have a mate who lived in a 1970s housing estate in Cork, and they all got external insulation done through a community grant. The whole estate looked transformed and their heating bills dropped by nearly half. Fair enough, it took a bit of organising, but it was worth it.

5. The Solar PV Grant (For Generating Your Own Electricity)

Solar panels have become incredibly popular in Ireland. The grant for solar photovoltaic (PV) panels gives you up to 2,400 euro, which covers a significant chunk of the installation cost. You can also claim a separate grant for a battery storage system, though that is a smaller amount. Right so, if you are looking to reduce your electricity bill and maybe even sell excess power back to the grid, this is a no brainer. The energy upgrade grants Ireland 2026 now include a higher cap for larger systems, so if you have a big south facing roof you can go for a 6kW array. The average payback period is around 5 to 7 years, and with the rising cost of electricity that is only getting shorter.

What you need to know

You need a BER rating of C or better before you can apply for a solar PV grant. That is a new rule that came in this year. So if your home is poorly insulated, you need to do that first. But once you have the insulation sorted, solar is the next logical step. Remember, you can always find a rental property with solar already installed on Findivo if you don't want to do the work yourself.

How to apply for your grant

Applying is straightforward once you have your contractor lined up. All applications go through the SEAI website. You need to create an account, fill in your details, and upload the BER certificate and contractor quotes. The SEAI processes applications in about four to six weeks. To be honest, the biggest delay is usually getting a contractor to give you a timeline. Demand is high, so book early. I recommend registering on Findivo to get alerts when new properties with energy upgrades come on the market, because a well upgraded home is a hot commodity.

Anyway, that is the top five energy upgrade grants Ireland 2026 you need to know about. Whether you are a homeowner, a landlord, or someone looking to buy, these grants can save you thousands. The government is betting big on retrofitting, and the money is there for you to claim. So get a BER assessment, talk to a registered contractor, and start the process. Your wallet and the planet will thank you.
