Cardiff University undertook some work with us, which sought to have discussions right across the public sector where the invest-to-save programme had been used, and it's been used right across Wales in a range of ways to understand what the barriers were for the implementation and expansion of those good projects and the learning across Wales so that these kinds of interventions could be made without the need for the invest-to-save funding. So, we are still considering, really, the learning of that, and it was very much about ensuring that there are opportunities for collaboration and for sharing that information. But we are currently exploring and considering how the fund will operate in future, what activities it should focus on, and part of that will be considering the learning about the barriers to the expansion of good practice.
