There’s a lot of discussion at the moment about whether retrofit grants in Ireland are actually worth it for homeowners.
The Government is now allocating over €500 million a year to SEAI home energy upgrade grants, with targets to retrofit hundreds of thousands of homes by 2030. But uptake hasn’t matched that ambition, and some schemes have seen relatively low demand.
For many people, the issue comes down to cost.
Even with SEAI grants:
- Basic upgrades can cost €5,000–€15,000
- Deep retrofits can run from €30,000 to €100,000+
There are also ongoing concerns about the one-stop-shop retrofit model. While it simplifies the process, it can limit choice and competition and in some cases, push prices higher due to lack of competition.
Recent changes have introduced more phased options, which can help with the cost burden. But for most homeowners, the upfront spend is still hard to justify.
With energy costs climbing and significant fears of further increases, improving energy efficiency is set to remain high on the agenda for many people.
Retrofit grants for landlords: the tax angle
One key difference that often gets overlooked is that landlords can claim tax relief on qualifying retrofit costs. This applies to the portion of the cost not covered by the SEAI grant and is deducted against rental income. That means it reduces income tax, USC and PRSI. The grant reduces the upfront cost and the tax relief reduces what’s left.
Example: how landlord retrofit tax relief works
- Total retrofit cost: €20,000
- SEAI grant: €13,000
- Remaining cost: €7,000
The remaining €7,000 can be claimed as a rental expense which can significantly reduce the real cost of the works.
Why this matters:
For landlords, this changes the calculation.
- The net cost of upgrades is lower
- The property becomes more energy efficient (and easier to let)
- It helps future-proof against tighter regulation
For tenants, the impact is just as important:
- Lower heating bills
- Better quality homes.
When is retrofit tax relief clawed back?
The relief is conditional and can be clawed back if the property:
- Is sold
- Is taken out of the rental market
- Is used for short-term letting
within a set period after the work is completed.
There are common-sense exceptions for example, if a tenant leaves and the property is re-let, there is no clawback f the relief. The relief is designed to support long-term rental supply, not short-term tax gains.
Are retrofit grants worth it?
For homeowners, the hesitation is understandable:
- High upfront costs
- Long payback periods
- Limited flexibility in how works are carried out
For landlords, the position is different.
When you combine:
- SEAI grants
- Rental expense tax relief
…the numbers are often much more workable.
In Summary
Ireland needs to accelerate energy upgrades, particularly with energy costs where they are.
The funding is there, but the system still needs to feel straightforward and worthwhile on an individual level.
At the moment, retrofit grants don’t feel feasible in all cases, but for landlords, they can make far more financial sense than they first appear.
