Infrastructure Bill [HL]

Debate between Baroness Maddock and Lord Bishop of St Albans

Wednesday 5th November 2014 Lords Chamber

[The Lord Bishop of St Albans]

My Lords, in speaking to Amendment 108A, I should like to thank the noble Lord, Lord Berkeley, for co-sponsoring it. I bring forward this amendment out of concern that the standard proposed in the Bill is significantly lower than that already agreed through cross-industry consensus. I fear that an excessive focus on off-site carbon savings will undermine the effectiveness of the proposals and that an exemption for small sites will create confusion by causing the emergence of a two-tiered regulatory system. It is essential that housebuilders meets the carbon compliance standards that have already been agreed through cross-industry consensus. This was endorsed by the Government back in 2011 and strongly supported by around 70% of those responding to their consultation. I am therefore troubled by the proposal of a new on-site energy performance standard for zero-carbon homes that is lower than the one already agreed. It is not clear why this reduction is necessary. The proposed exemptions from the standard for homes built on small sites and for starter homes would also serve to undermine the main purpose behind the zero-carbon standard: namely, that of prioritising carbon reduction. It is to address the lack of measures necessary to realise the Government’s stated commitment to carbon neutrality that I have tabled this amendment which requires the previously agreed carbon compliance standard to be met on-site before allowable solutions can be undertaken. It also requires all homes to meet that standard, ensuring that no exemptions are allowed.

First, I will address zero-carbon standards. Your Lordships’ House will be aware that the zero-carbon homes standard was originally created by the Zero Carbon Hub set up by the previous Government. This involved the green technology industry, developers and the Government. Together the decision was taken to set the standard based on what was technologically available back in 2010-11. As this Bill is addressing homes that will be built after 2016, what is technologically achievable will be far greater than the minimum standard set out back in 2011. The cost and viability of these technologies will have improved along with their accessibility and reliability. It is therefore difficult to see on what basis the Government have drawn their conclusion that the previously agreed standards are now unworkable. Surely standards must be set at the optimal point, which has been previously agreed through intense cross-sector scrutiny, and must be consistent across the board. There should be a common standard regardless of the size of the development.

It is essential that these agreed standards apply to all homes, especially starter homes where tight budgets are more likely to squeeze out energy-saving measures. The proposed exemptions for small sites are problematic as such sites are much more likely to be in rural areas that are off the gas grid and therefore expensive to heat. We must not allow this Bill to be a means of compounding the desperate situation of those households already struggling with fuel poverty. As we have already heard, there is currently a lack of clarity over what comprises a small site. A consultation on small sites was promised before the summer but has yet to take place. It would be very helpful if, in his summing up, the Minister could tell the House when the consultation can be expected. As many as 12.5% of homes a year could come under the small sites exemption if these sites are classified as 10 units or fewer.

It is also as yet unclear which parts of the zero-carbon policy the exemption refers to. Does it refer only to the allowable solutions flexibility mechanism, which can be used to top up the carbon savings from code level 4 to level 5, or will developers of small sites be exempted even from the code level 4 on-site standard? The proposed reduction to code level 4 is in itself damaging and unnecessary. Three of the country’s largest housebuilders have recently shown that code level 4 compliance can be achieved primarily through improved efficiency of the building fabric, in the form of insulation and glazing, and not requiring any expensive renewable energy technologies. Furthermore, these developers have stated that they expect to be able to build these code level 4 homes, when delivering at scale, to the same price as it currently costs to build to the 2010 code level 3 building regulations.

In the immediacy of economic pressures, we must not lose sight of the overriding purpose for which the zero-carbon standard was designed. The recently published IPCC report reiterated the very real dangers of anthropogenic global warming and the concurrent impact on humanity across the world. Carbon reduction is essential to climate change adaptation and mitigation.

Briefly, and in passing, I am also glad to say that my own church, the Church of England, is playing its part. Vicarages and other properties are now normally being built to the highest green standards and more than 400 of our church buildings, many of them medieval, now have some form of renewable energy.

In conclusion, the Bill would lead to confusion in the supply chains and among house buyers, a two-tier regulatory environment and greater fuel poverty. Moreover, the large-scale exemptions signal a retreat from a full-blooded commitment to reducing carbon emissions, the goal on which the future flourishing of our country as part of the global community depends.

[Baroness Maddock (LD)]

My Lords, I have a great deal of sympathy with the comments of the right reverend Prelate the Bishop of St Albans. I spoke on these issues in Committee. As has been said by both previous speakers, we managed to get such agreement across the building sector and all the organisations that care about these issues as to what the standard would be. When we came in as a coalition Government, we stuck to that. For some reason, we changed our minds. I would really like the Minister to explain what made us question the agreements we had and the standards we had wanted.

I know that two of my honourable friends who have been Liberal Democrat Ministers in the department have pushed to row back from where we were going, and we have now gone forwards again. However, we have not managed to get any farther. We are owned an explanation from the Minister tonight of why we have ended up in this position when we had such a good agreement back in 2010.
