What SEAI registration for Windows and Doors means

Each company listed below is currently registered with SEAI for the External Windows and Doors measure required for grant supported window and door replacement work. This is a factual registration status only. It does not mean that SEAI or Upgrader.ie approves, endorses, vets or guarantees the company or its workmanship.

What to check before choosing a windows and doors installer

For the SEAI windows and doors grant, the installer must be registered with SEAI for external windows and doors, the home must already have adequate attic and wall insulation, and replacement windows must achieve a whole window U value of 1.4 W per square metre K or lower. The grant is currently up to €4,000 for windows in a detached house, less for other dwelling types, and €800 per external door for up to two doors, and it must be approved before work starts. Ask each installer to state:

• The whole window U value for your own windows, in writing, not a centre pane or glass only figure.
• The frame material and glazing specification, and the U value of any door.
• How the windows will be fitted, including insulation around the frame, internal airtightness, external weather sealing, sills and drainage.
• Whether a survey is included, and who makes good the reveals and finishes afterwards.
• If wall insulation is planned, how the window position will be coordinated with it.
