Under the terms of my Department's Housing Aid for Older People (HAOP) grant scheme, which is administered by individual local authorities, grants of up to €10,500 are available for the carrying out of necessary repairs or improvements to a house. The types of works allowable under the scheme can be varied and may include repairs to/replacement of windows and doors which, in the opinion of the local authority, are considered necessary to make the house habitable for the lifetime of the occupant.
Outside of the HAOP scheme, there is no specific grant scheme currently available from my Department for the replacement of windows in private dwellings and I have no plans to introduce such a scheme.
