I thank the Minister for that response and, for the record, I'd like to thank Vikki Howells for presenting the report in the cross-party group this morning. There is cross-party support for developing such proposals, and therefore I look forward to seeing the steps that will be taken to that end. 

If I could move on to retrofitting, please. Fuel poverty is a huge problem across Wales, as you know, and as a Member for Dwyfor Meirionnydd I am aware of the detrimental impact of fuel poverty on communities there. We have the oldest housing stock in western Europe and they are among the least efficient homes in terms of energy. This leads to many people having to choose between heating their homes or eating—a choice that no-one should face. The price of fuel is at its highest and the cap on energy prices is to increase by 54 per cent from 1 April, as you know. Those on a default tariff who pay by direct debit will see an increase of between £693 and £1,971 on average per annum. This will push over 0.25 million people in Wales into fuel poverty. 

We need to tackle fuel poverty now, more than ever, by responding to the crisis and improving energy efficiency in homes. It's worth noting too that 10 per cent of carbon emissions in Wales come from residential property, and solving fuel poverty will help us to fight climate change too. The social housing sector will be crucial as we decarbonise our homes and ensure that the economic benefits of doing that remain in Wales. It's a challenge that we need to face over the next 10 years. The Minister will appreciate, of course, that decarbonisation of homes can't be implemented without the right combination of grants, private funding, regulatory standards and a clear road map set out. 

The final budget—
