Finance Bill

The most difficult part of the proposal is that it is likely to increase demand rather than deal specifically with those who supply housing. We need incentives for the people who develop property as well as for those who want to purchase it. The incentive will have an indirect effect if we go straight to the demand side. A significant number of new properties will be built in my constituency. We already have difficulty convincing the developers that there is a demand for energy-efficient properties. Although the proposal provides an incentive, I am not sure how much it will do to convince property developers of the case. There is so much unmet demand that they could simply build unenvironmentally friendly houses and still have no problem selling them. That is the core of the difficulty for me. I welcome the Government amendment, because it means that we will be able to move on from the hypothetical and extended debate that we had in Committee, and are reliving today, to a more tangible one about what a zero-carbon property will be. I look forward to seeing the regulations, because—given my experience in my constituency—the Bill raises some key questions about what a zero-carbon property means. Does it mean zero-carbon in terms of running costs or the energy required to build the property in the first place? The Mount Pleasant ecopark just outside my constituency undertook to try to build workspace with as minimal an impact on site as possible. It was constructed with materials already on the site, instead of by bringing in cement and other building materials. That was a brilliant initiative and the resulting workspace has been taken up quickly, but it met with huge difficulties, including in securing the permissions and in developing the technologies to do it. For example, the walls of the property are made out of rammed earth from the site, and the result is a beautifully coloured surface, but some bizarre tests had to be carried out to prove that it was strong and durable enough. The tests included dropping a piece of the earth from shoulder height and if it broke into between three and seven pieces, it was appropriate for rammed earth construction. The expertise and techniques involved could bring huge benefits, but it is not clear whether the Minister intends it to develop it that far. That will need to be made clear in regulations, because if the proposal is to be truly ambitious it should include not only the energy use of the building after it has been built, but minimising the impact that new build has on the environment, not least because some ambitious targets have been set for meeting the demand for homes. On the Opposition amendments, I agree that the regulations should include the method for claiming stamp duty relief, and I understand that that is the intent of amendment No. 6. I wonder whether the methods that have been mentioned will be affected by the Government’s change in policy on home information packs. In Committee, it was pointed out that Cornwall is an objective 1 area, so there was an opportunity for new workspace to be part funded by that programme. Because of the huge demand, the opportunity was taken to set higher environmental standards. The problem was that there was no one within a 300-mile radius who was able to assess whether that workspace met those criteria. So we must not only set high aspirations but ensure that there is a way of delivering them. The obvious way would be through the home information pack process, but that has now been seriously undermined. We already know about the difficulties of finding the capacity to deliver that. Amendment No. 7 would introduce a sunset clause of one year. I wonder whether it might have been more practical to have a mechanism for reporting back, so that we could judge the effectiveness. Key questions remain, including how many people will benefit. We have had contradictory information from the Red Book and what Ministers have said. Fundamentally, the issue is that if we are serious about making homes more energy efficient, we have to tackle the existing housing stock, because the majority of it will still be standing in 50 years’ time. Unless we tackle that issue, people will find it difficult to make their own individual effort to tackle climate change. There are some good practical examples, such as social housing stock in my constituency that has been retro-fitted with a ground source heat pump which has reduced the environmental impact of those properties and is also saving the people who live in them hundreds of pounds a year in heating bills. If we do not look at existing housing stock, what we can achieve through this mechanism will be severely constrained.
