My Lords, I thank my noble friend Lord Teverson for tabling this amendment. I also thank the noble Lord, Lord McKenzie, for his comments.
I should say at the outset that I share the sentiments expressed on the objective of ensuring that more homes are built, and built according to better standards and in line with standards. My noble friend’s proposed amendment sets a six-year time limit on a development being built to the energy performance requirements in building regulations in force at the time that planning permission was granted for the development.
I should start by pointing out that, as noble Lords may be aware, it is not the grant of planning permission that is the trigger for the application of building regulations’ requirements but the submission of a plans application or a building notice, or an initial notice to the building control body. During my time in local government, I remember many applications that were challenging in that regard. Therefore, we think that the amendment as drafted may lead to confusion about what happens under planning as opposed to what happens under building regulations.
However, setting to one side the issues that may arise from the drafting of the amendment, there are important practical considerations about how new building regulation requirements apply to developments already under way at the time that the new regulations are introduced. It can take a long time to plan, design, finance and build a development, as noble Lords know. It is therefore correct that the building regulation provisions in force when the building regulations application is made remain those with which the development must comply. To provide otherwise would lead to unreasonable disruption, perhaps delay, and increasing financial burdens as there would be uncertainty about construction standards and a risk of disruption to the supply chain part way through the development.
For example, large developments such as the famous “cheese grater” building in Leadenhall Street, London, will take many years to build and complete—often longer than six years. If accepted, this amendment would mean that the technical requirements of those developments would need to be changed part way through construction. Forcing a development to change from one set of building regulation requirements to another half way through a project would cause real problems for builders, as I am sure my noble friend would recognise.
However, in saying that, I put on record that I totally understand and appreciate my noble friend’s concern that developers may play the system by submitting a building regulations application and then doing nothing or delaying the development and not having to meet any more up-to-date requirements that may have been introduced in the mean time. From my experience, I have seen that happen, too. The Government have recognised this issue and so building regulations generally require that whenever any changes are made to building regulations, building work in respect of any applications made before the coming into force of the new requirements must commence at the latest within 12 months—otherwise, the new requirements will apply.
This requirement was introduced in 2006. Before then, as noble Lords will know, the time limit was three years. This time limit is set in the building regulations. This gives the opportunity to adjust the time limit in light of the circumstances when new regulations are introduced. If we were to rely on changes to primary legislation, we would then lose the flexibility to respond. If we state the time limit at an inappropriate point, we could cause real problems for housebuilding, as I have already outlined. It will be for the Government dealing with building regulations changes for 2016 to consider what time limit may be appropriate. I am sure that they will read this debate very carefully to see the issues raised and the views expressed. I believe that my noble friend recognises that the amendment as it stands focuses only on one specific area of building regulations, the energy performance requirements. The time limit which I have just described applies in respect of any change to the standards in the building regulations. Therefore I am sure that my noble friend recognises that it may lead to confusion for developers if different time limits apply to energy performance requirements than to other requirements of building regulations.
The amendment from my noble friend, as the noble Lord, Lord McKenzie, has said, raises an important issue. However, as drafted, it would not work for the practical reasons that I have outlined. I hope that I have set out in some detail the time limit which already operates in building regulations to tackle the risks of developers who seek to just get regulations in place for the sake of it. There will be an opportunity in the consultation on the 2016 regulations for energy performance requirements to be looked at. I hope that, in the light of the assurances and clarifications that I have provided, my noble friend will be minded to withdraw his amendment.
