My Lords, I draw the attention of the House to my relevant interests as a vice-president of the Local Government Association and as a councillor. I apologise to the House that, due to train delays, I was unable to speak at Second Reading, though I was here for most of that debate, bar for about three minutes.
This Bill is broadly accepted—certainly by those of us on our Benches—but there are some additions which we think would make it better. Back in July, when my noble friend Lady Thornhill and I tabled this amendment on energy efficiency, little did we know that the issue would be even more in the public eye and even more important to address in a strategic way. The amendment, which adds the words “energy efficient” to the fundamental objectives set out in Clause 1, must surely now be a priority for any Government.
Our country’s energy security is finally at the heart of government thinking. The cost of energy for tenants—many of whom will be among those with the lowest incomes—means that they will be completely unable to meet their basic needs. Improving energy efficiency is one of the key planks of a longer-term strategy to ensure energy at a cost that can be afforded. As this is undeniably the case, I hope that the Minister will be able to accept the amendment.
Houses in Britain are some of the worst insulated in Europe—it is shameful to have to say that, but it is true. The Government aim to improve the energy efficiency of homes, but what appears to be lacking is a practical plan to achieve those absolutely essential improvements.
The properties in the social housing sector will, in the main, have been built post-1920, when cavity walls became the norm. One-third of heat loss is through walls. Prior to 1990, cavity wall insulation was not the norm, although it can be done relatively easily. Ensuring that loft insulation is 300 millimetres deep—the current new-build standard—will also help, as will double glazing, although the majority of properties will already have double glazing, albeit at the lower efficient level installed at the time. The Government have the stated intention of exchanging gas boilers for heat pumps, which are effective only with very well insulated homes. Therefore, achieving more energy-efficient social housing should be a priority, which is the purpose of the simple amendment that we have laid today.
Achieving better energy efficiency is not difficult if there is a will to do so. When I was leader of Kirklees Council, about 15 years ago we had what we called the warm zone scheme, which provided free loft and cavity wall insulation to all homes, regardless of tenure—not just social housing but all homes—and which was part- funded by a levy on energy companies. In total, nearly 100,000 homes benefited. If it was that easy to do—to be honest, it was not that difficult—it can be done now on a nationwide basis, and ought to be done. It is practical but will happen only if the sector is required to make it a priority; hence the purpose of the amendment.
