How Much Can New Windows Save on Energy Costs?
Replacing old single-pane windows with new energy-efficient ones that have double or triple glazing could reduce your energy bills by €100 to €400 per year.

These savings demonstrate the long-term benefit of availing of the SEAI grants for windows and doors.

The cost of new windows and doorsvaries depending on many factors, such as size, style, and material. New windows usually range from €450 to €1,700 per window. A new door costs around €700. These costs are often offset by the available SEAI grants for windows and doors.
Windows typically last for 20 to 25 years. While aluminium windows are more susceptible to dents, vinyl window frames, such as uPVC, can last for up to 40 years. Other external factors, such as extreme weather conditions, can also affect how long your windows will last. Investing through SEAI grants for windows and doors ensures a long-term benefit.
It’s best to replace windows in the spring or early summer. Not only will you avoid letting in a cold draft, but some materials, such as caulk, should only be applied when the temperature is above 5 degrees Celsius.
If your windows are inefficient, and it’s the middle of winter, you don’t have to wait until the warmer months to replace them, however. By going ahead with the work, you will likely notice an extreme increase in your home’s comfort level once the new windows are installed. Many companies also offer discounts during the off-season for windows and doors installation.
For any of the SEAI home improvement grants mentioned above that contain funding towards replacement doors and windows, you can apply online through seai.ie.
There isn't any particular scheme or grant for window and doors aimed exclusively at pensioners.
Any homeowner, whether they are retired or still working, are free to apply for funding from the SEAI for home upgrades that October include funding towards replacement windows and doors.
