If you've got a VELUX roof window that's seen better days, we've got good news. The Irish government has expanded the SEAI grant scheme to include roof windows. Which means you could get up to €4,000 funding when you upgrade to a more energy-efficient model.

SEAI Window Grant amounts: How much could you get?

The SEAI window grant is a flat amount per property type - it’s not calculated per window. So, you can apply for funding, even if you’re only planning on replacing your roof windows.

For a detached home, that's €4,000 back in your pocket. An attractive amount for a job that could also make your home warmer, quieter and more comfortable.

Where VELUX comes in

Our Supply & Fit service takes care of the whole roof window replacement process - and because we work alongside a network of SEAI-registered installers, you won't need to go hunting for a registered contractor yourself.

Important: You will still need to send off your own SEAI Grant application.

On the technical side, VELUX standard double-glazed roof windows have a U-value of 1.3 W/m²K – this is already better than the 1.4 required by SEAI.

SEAI Window Grants – Roof window FAQ

Can I get an SEAI grant for replacing a VELUX roof window?

Yes. Roof windows are eligible under the SEAI windows grant. They are treated the same as any other window upgrade in your home.

Your home must have good attic and wall insulation in place before you apply.

See the SEAI website for full details and definition of “good” insulation. 

 

Do I need to supply anything to prove the age of my old roof windows?

No, you do not need to provide proof of age, or performance, for your existing roof windows. The SEAI requirement is that your home was built before 2011.

If your roof windows are 20+ years old, the time may be right for an upgrade. 

 

My home was built after 2011 - am I eligible?

No - the grant is only available for properties that were built and occupied before 2011. Extensions added after 1 January 2011 are also excluded, even if the main area of the house qualifies. 

How much is the SEAI windows grant?

The SEAI window grant amounts depend on your property type:

  • Apartment: €1,500
  • Mid-terrace: €1,800
  • Semi-detached or end-of-terrace: €3,000
  • Detached: €4,000

What U-value does my new roof window need to achieve?

The replacement roof window must achieve a U-value of 1.4 W/m²K or better (i.e. 1.4 or lower). A lower U-value means better insulation performance.

Modern VELUX roof windows meet or exceed this standard: our standard double-glazing (70) has a U-value of 1.3 W/m²K.

If you’d like to make the most of your upgrade, you can improve this even more by choosing a triple-glazed VELUX roof window, for boosted insulation and noise-proofing.

Our friendly Supply & Fit service team will happily chat through your options. 

Can I get a grant for just for roof windows, or does it have to be the whole house?

The SEAI grant is a flat amount per property type - it is not calculated per window. So, you can choose to upgrade only your roof windows if the rest of your home’s glazing is already sufficient.
