Dr. Ciaran Byrne:

We have. A significant amount of work was done in the establishment of the grant rates. That included looking across all our existing schemes.

We surveyed the market twice last year because of inflation and did a good deal of behavioural research including demographically selected focus groups. It looked across the income spectrum, the age spectrum and the home-owner types and we landed on the current grant levels. However, we are on a journey so what we start off with in 2022 will quite likely not be what we will be doing in 2028 or 2030. We are evolving this programme because we have so many targets to reach.
