The number of home energy upgrades completed between January and March of this year and supported through the Government funded SEAI grant scheme increased to 9,946.
That is a jump of 172% when compared to the same three month period last year.
The SEAI aims to support over 37,000 home energy upgrades this year, as part of its retrofitting target.
It said it expects this target will be reached, or surpassed.
Today's figures show that 3,304 homes were upgraded to a BER B2 or higher in the first quarter, up 232% on the same period in 2022.
3,440 attic and 2,605 cavity wall measures were carried out, while 781 heat pumps were installed.
Meanwhile, 946 fully funded upgrades for low-income households were completed during the three month period, up 27% on 2022.
The highest number of energy upgrades were carried out in County Dublin, followed by Cork, Galway and Meath.
The SEAI said it processed more than 15,600 grant applications across all schemes, up 76% on the same time last year.
"It is encouraging to note that project completions are up considerably this quarter, particularly in the individual energy upgrade grants," said Dr Ciaran Byrne, Director of National Retrofit at SEAI.
"Since the launch of the One Stop Shop scheme last year, there have been over 2,200 Home Energy Assessment (HEA) applications which suggests that a healthy pipeline of homeowners is completing the initial energy survey to determine what energy upgrade works they wish to complete," he added.
Mr Byrne said they believe the increased interest in home energy upgrades is driven, in part, by homeowners responding to increased energy bills.
"There are now grant options to suit all budgets and requirements," he added.
