I recognise the excellent work that's been done through the optimised retrofit programme, which has certainly improved a lot of our social housing. I look forward to hearing the detail of next year’s net-zero skills plan, because that is going to be crucial in enabling the construction industry to plan for having the skills they need to decarbonise all our homes.

I appreciate the Welsh Government’s ambition is tempered by at least a £1 billion cut in its budget next year. Nevertheless, there are many ways in which the cause of decarbonising the private sector can be advanced, particularly when 40 per cent of all Welsh homes are owned outright with no mortgage attached. Whether it's individual building passports or fiscal incentives through a reduction in stamp duties or land value tax, how can we galvanise people who have the resources to invest in reducing their heating bills and do the right thing by the environment?
