Ms Niamh Randall:

I will begin with the CALF model and rents. Our arrears are under 3%, at approximately 2.6%. We work within the differential rent model, which means that, as people's circumstances change, rents can be revised upwards and downwards. This makes things more affordable. It is particularly important during this cost-of-living crisis that people have that option available. It is working at this point.

I do not have figures to hand on vacant stock and accessibility, but I will be happy to share the information with the Deputy outside of the committee.

The Deputy made a point about maintenance. Retrofitting is really important, particularly in the context of older AHBs. We have been in existence for 40 years. As a result, we have stock that is 40 years old. With this stock, environmental considerations, fuel poverty and energy ratings are important. We need to ensure that there is funding for retrofitting. In the context of the cost-of-living crisis, how much it can cost people to heat their homes, particularly if those homes are not energy efficient, also comes into play.

What was the question about the SLI model?
