Ms Margie McCarthy:

As the Deputy is aware, the heat loss indicator, HLI, is the marker we use to define whether a person is grant eligible. That is in place to protect homeowners against high electricity bills when running a heat pump in a non-insulated or leaky home. The HLI study is to consider whether, with heat pump technology vastly improved and looking at varying home insulation, we could increase the HLI to allow a broader range of homes to go into it. The study has commenced but it has not read out yet. We have designed it to have readouts with milestones. As such, even though the completion of the study may be two years down the road, we will have readouts in one year's time so that we can start to help to inform decisions on the matter.
