SEAI Warmer Homes scheme

Has anybody availed of the SEAI Warmer Homes scheme where the SEAI cover the whole cost of home upgrades? Turns out we might be eligible but was wondering if anybody has experience with it and did it work out well? Our house is relatively modern (BER B2) so we may not be able to do too much but would be interested to see how it could turn out. Thanks in advance ☺️
