Planning and Infrastructure Bill

Debate between Lord Gascoigne and Baroness Hayman of Ullock

Committee stage
Wednesday 17th September 2025 Lords Chamber

[Baroness Hayman of Ullock (Lab)]

I thank noble Lords for taking part in this debate on the mitigation hierarchy. I have listened carefully and very much recognise the concerns that are being raised. These amendments seek to add provisions that require Natural England and the Secretary of State to apply the mitigation hierarchy when considering whether to produce an EDP, and in its production and implementation. By introducing a more strategic approach to addressing the impact of development, the Bill deliberately provides an appropriate degree of flexibility to Natural England to design conservation measures to deliver improved outcomes for the environmental features that are subject to an EDP. The noble Lord, Lord Gascoigne, when he introduced his amendment, noted that the NPPF includes consideration of the mitigation hierarchy in respect of individual planning applications. I was not going to mention it, but because he did, I thought I had to.

As we have set out, the NRF is a strategic model. While I want to reassure noble Lords that the mitigation hierarchy lives in this model and is integral to the model we are trying to get across, it cannot be considered in the same way as an individual planning application. Again, I stress that the NPPF is a statutory model. You cannot just ignore it. It is part of the application process. So, we would expect Natural England to consider this throughout the process and use tools such as the ability to request planning conditions to avoid and reduce impact as key elements of an EDP. In preparing an EDP, Natural England will always be mindful of the benefits of avoiding impacts before they occur. Taking action locally which benefits the same protected feature that is being impacted by development will be the default under an EDP. This places a kind of ecological lock on the use of network measures, which can be used only in cases where it is clear that taking action elsewhere would be more beneficial to the environmental feature.

In addition, when making the EDP, the Secretary of State will have due regard to the environmental principles policy statement, in line with the Environment Act 2021. This will ensure that important principles, such as the precautionary principle and the rectification at source principle, are considered. Ultimately, the overall improvement test will require that each EDP demonstrates how the conservation measures will secure an environmental uplift that goes beyond the offsetting that is achieved under the current system.

Returning to Amendment 245, as I said, the principles are already incorporated into the existing provisions and further reinforced by the amendments we have tabled. As the noble Baroness, Lady Parminter, said, Natural England can request that planning conditions be imposed on development, ensuring that impacts are minimised. As I have explained, network measures can be implemented only when doing so would lead to greater improvement. The noble Baroness asked for future information. Let us get together before Report; I will get that information for her and share it with noble Lords.

Natural England will always consider the environmental principles when preparing an EDP, and the Secretary of State may make one only if it meets the overall improvement test. Therefore, the additional flexibility provided for by the nature restoration fund can be used only to deliver better outcomes for the environment.

I turn to Amendment 251 in the name of the noble Earl, Lord Russell, and Amendment 301 in the name of the noble Baroness, Lady Willis, who is not in her place. These amendments would require a developer to demonstrate that they have applied the mitigation hierarchy before Natural England can accept their request to use an EDP. The clear aim of the nature restoration fund is to deliver a win-win for both development and the environment. A fundamental element of delivering this is to reduce the amount of time and money spent on individual environmental assessments and refocus these efforts on strategic action to improve environmental outcomes at scale.

The EDP itself is required to consider the impact of relevant development on the environmental feature and propose appropriate measures to address and materially outweigh this impact. The plans will be underpinned by the best scientific evidence and will include actions to avoid impact, as well conservation measures to address and outweigh impact. As such, requiring developers to undertake individual assessments risks eroding the value of the EDP, adding costs to individual development, which we think would reduce the utility of relying on EDPs. Where an EDP is in place, the overall improvement test ensures that outcomes for the environment will be better than the existing system, so it is vital that we embrace the opportunity to streamline the process in order to deliver this win-win.

The noble Earl, Lord Russell, tabled Amendment 275, which seeks to require that Natural England may decide to prepare an EDP for a protected feature only if two conditions are met: first, that Natural England has followed the mitigation hierarchy; and secondly, that the EDP would contribute to a significant environmental improvement in the conservation status of the relevant environmental feature at an ecologically appropriate scale. I have just addressed the first condition, so I will focus on the second.

The existing provisions in the Bill already require the Secretary of State to consider whether the overall improvement test is met once a draft EDP has been prepared and presented. Requiring Natural England to consider that same test at an earlier stage would not be possible because neither the detail of the proposed conservation measures nor the environmental impact of the development it is intended to address would be known at that stage. We think that the correct point to apply the overall improvement test will be after the EDP is drafted, not before.

The amendment also proposes a modification to the overall improvement test to require that conservation measures significantly and measurably outweigh the environmental impact of development. This was addressed previously, so I will not repeat it here, except to say that the Bill requires that conservation measures must address the environmental impact of development and, additionally, contribute to an overall improvement in the conservation status. We have clarified that with the amendments we have tabled.

Turning to Amendment 256ZA, tabled by my noble friend Lady Young, the Government’s amendments to Part 3 make it clear that network measures may be taken forward only when Natural England can set out how the approach will make a greater contribution to the improvement of the conservation status of the feature than an on-site measure. We are clear that the flexibilities will not come at the expense of action to avoid impact, and the Bill provides powers to address such actions and secure that they are taken through the use of planning conditions. There is also the opportunity to scrutinise the proposed conservation measures, including actions proposed to avoid impact, during the consultation on each EDP. The Secretary of State will also have due regard to the environmental principles policy statement, and see that other important principles are considered.

Turning to Amendment 340, tabled by the noble Baroness, Lady Grender, the overall improvement test is central to the nature restoration fund. I have gone into some detail about how that is supposed to work, but the proposed requirement to apply the mitigation hierarchy rigidly would restrict an EDP’s ability to meet the overall improvement test strategically. As I said, an EDP cannot be made unless the Secretary of State is satisfied that it will meet this test. Any flexibility in applying the mitigation hierarchy should be seen through this lens. The nature restoration fund does in limited circumstances allow Natural England to propose conservation measures which benefit the environmental feature in a different location.

Turning to irreplaceable habitats, the Bill does not amend or disapply the NPPF. Therefore, the existing policies remain unchanged. An EDP could be applied to an irreplaceable habitat only where it was also a feature of a protected site. Even then, an EDP could not allow for the loss of irreplaceable habitats, as it would simply not be possible to satisfy the overall improvements test in these circumstances. Finally, it is not clear what the proposed requirement to consider enhancing biodiversity would add, as the Bill is clear that an overall improvement must be achieved in relation to the protected feature to which the EDP relates.

Finally, on Amendment 346DF, in the name of the noble Lord, Lord Roborough, we have recently concluded a consultation on improving the implementation of BNG for minor, medium and brownfield development. Among the options is a proposal to streamline the BNG metric process. We might be interested to pick this up and discuss it further, because the Government are currently considering their response, and we will be publishing our outcomes in due course. New legislation requiring government to lay a report on this matter is therefore not necessary at this stage, so I hope the noble Lord will withdraw his amendment.

This has been a really important debate. It has raised a number of issues which I am aware that noble Lords would like to discuss further, and this is something we should specifically pick up in discussions ahead of Report. With these explanations, I kindly ask noble Lords not to press their amendments.

[Lord Gascoigne (Con)]

I am grateful to all noble Lords who spoke to that group, not least the Minister. I apologise for incorrectly prejudging what I thought she would say—I obviously got it completely wrong, and I apologise.

The noble Earl, Lord Russell, got it right when he said that this group and the previous one are the nub of the problems with the EDP Part 3. I am not saying there are other things, but this goes to the heart of how we try and make the Bill a win-win for both development and nature. I do not want to dwell too long. I am grateful that the Minister said that we will come back to that. It is worth our coalescing and having another shot at it, if we may, but, with that, I beg leave to withdraw my amendment.
