Planning and Infrastructure Bill

Debate between Baroness Scott of Bybrook and Earl of Lytton

Committee stage
Tuesday 9th September 2025 Lords Chamber

[The Earl of Lytton (CB)]

My Lords, the noble Baroness, Lady Bennett, invited me to acknowledge that other jurisdictions do this better. I entirely agree, but they do not always have the same regulatory baggage that we in this country seem to have; perhaps there is something that can be unpicked and dissolved there.

[Baroness Scott of Bybrook (Con)]

My Lords, before I turn to the substance of the amendments in this group, I begin by thanking the noble Lord, Lord Khan. Although he sat on the Opposition Benches, he always approached his shadow ministerial duties in your Lordships’ House with courtesy, commitment and friendship. He was diligent, engaged and unfailingly respectful in his dealings with me and my team. While we did not always agree, I greatly valued the constructive spirit he brought to our debates, and I wish him well in whatever lies ahead; I will miss working with him.

I thank my noble friend Lady Hodgson of Abinger for tabling these probing amendments, which raise important issues about the way we prepare our housing stock for the future. Amendment 115, on rainwater harvesting, Amendment 116, on communal ground source heat pumps, and Amendment 117, on solar panels, speak to the wider challenge of how new homes can be made more resilient in the face of climate change. The principle of future-proofing is one most of us would support, but the question for government is how far and at what cost such measures should be mandated, and the practicality of doing so. Can the Minister clarify whether, in the Government’s view, current building regulations, as mentioned by my noble friend Lady McIntosh of Pickering, already provide the right framework to encourage technologies such as rainwater capture, ground source heat pumps and solar panels, or is further regulation envisaged? Has the department carried out an assessment of the costs and benefits of making such systems compulsory, including the potential impact on house prices and affordability, and how these costs might be lowered in the future? Has it also considered the capacity of local electrical grids to support these systems and other potential loads such as EV charging?

There is also a question of consistency. To what extent are local authorities currently able to set higher environmental standards for new developments, and do the Government believe this local flexibility is the right approach, or should it be centralised?

Finally, how are the Government weighing the balance between affordability for first-time buyers on the one hand and, on the other, the need to reduce the long-term costs to households and infrastructure of failing to invest in resilience? These are the issues I hope the Minister will address, because it is that balance between ambition, practicality and cost which must guide policy in this area.
