New windows make a home more airtight, so make sure ventilation is checked, with trickle vents or other ventilation, to avoid condensation.

- Get quotes from SEAI-registered window and door contractors.
- Apply online and wait for approval.

- Submit your paperwork, including a post-works BER if required.
- Receive the grant.
What will I actually pay?
New uPVC double-glazed windows for a typical three-bed semi in Dublin usually cost €6,000–€12,000. With a €3,000 grant, that's roughly €3,000–€9,000. A new front door typically costs €1,500–€4,000 before the €800 door grant.
Mistakes to avoid: replacing only some windows, forgetting ventilation, and ordering before grant approval.
