Attic Conversion Grants: What You Need to Know

If you’re considering an attic conversion in Dublin, one of the first questions you’ll likely ask is: are there grants available to help cover the cost? The good news is that while there isn’t a specific “attic conversion grant” in Ireland, there are several government-backed schemes that can significantly reduce the cost of upgrading your attic—especially when it comes to insulation and energy efficiency.

In this guide, Ultimate Construction breaks down everything you need to know about attic conversion grants in Ireland and whether you may qualify.

What Grants are available for Attic Conversions?

In Ireland, attic-related grants are primarily offered through the Sustainable Energy Authority of Ireland (SEAI). These grants focus on improving your home’s energy efficiency, rather than funding structural conversion works like stairs or dormer extensions.

The most relevant supports include:

Attic insulation grants
Rafter (room-in-roof) insulation grants
One Stop Shop retrofit grants (for full home upgrades)

For example, attic insulation grants typically range from €800 to €1,500 depending on your property type.
If your attic conversion includes upgrading insulation to modern standards, you could benefit directly from these schemes.

Who is Eligible?

To qualify for SEAI grants related to attic upgrades, you generally need to meet the following criteria:

1. Your Home must be Older

Most grants require that your property was built and occupied before 2011.

2. You Must Be the Property Owner

Eligible applicants include:

Homeowners (owner-occupiers)
Landlords
Approved housing bodies

3. Energy Efficiency Requirements Apply

For larger retrofit grants (like the One Stop Shop scheme), your home must:

Have a Building Energy Rating (BER) of B3 or lower before works
Improve to at least a B2 rating after upgrades

4. Work Must Be Done by Registered Contractors

To receive grant funding, all work must be completed by an SEAI-approved contractor and meet strict technical standards.

What Parts of an Attic Conversion Are covered?

It’s important to be clear: grants do not cover the full attic conversion.

Covered:

Insulation (attic floor or rafters)
Ventilation improvements
Energy upgrades linked to the roof space

Not Covered:

Structural alterations (stairs, dormers, raising roof height)
Interior finishes (plastering, flooring, electrics for living space)

However, combining an attic conversion with energy upgrades is a smart move. You can reduce your upfront costs while improving comfort and long-term energy savings.

How much can You Save?

Depending on your project, grants can cover a significant portion of costs:

Up to €1,500 for attic insulation
Potentially 50–80% of costs under larger retrofit schemes
Up to €75,000 total funding for deep retrofits via the One Stop Shop route

These savings can make a real difference when budgeting for your attic conversion in Dublin.

Why Combine Grants with an Attic Conversion?

An attic conversion is already a major investment—so it makes sense to maximise value by upgrading insulation at the same time.

Benefits include:

Lower energy bills
Improved BER rating (boosting property value)
Greater comfort year-round
Reduced carbon footprint

In many cases, insulation upgrades required for grants align perfectly with the work needed during a conversion—making it an efficient, cost-effective decision.

Final Thoughts

While there’s no direct grant for attic conversions in Ireland, you may still be eligible for substantial financial support through SEAI energy upgrade schemes. The key is understanding what’s covered and planning your project accordingly.
