Question

I have just a few hundred euros to get my two-storey, detached home in order before next winter. The BER is a D, and the rooms upstairs are chill and slightly draughty when the wind is to the south or east. The windows are double-glazed and about 20 years old. Should I throw all the money at an SEAI grant, and which one?
