Thank you for that response, Minister. Now, recent figures tell us that poor housing costs the Welsh NHS around £95 million per year in the first five years of treatment charges and costs Welsh society over £1 billion a year. Now, we can't afford to lose sight of that as, clearly, investing in good quality housing demonstrates there is a proven return on investment in health benefits. Therefore, can you tell us what the Welsh Government is doing to improve energy efficiency in its housing projects going forward, and what other measures is the Welsh Government taking to address the health costs of poor housing in Wales, and especially in Pembrokeshire?
