Question to the Department for Levelling Up, Housing & Communities:
To ask His Majesty's Government what assessment they have made of the report by the Home Builders Federation Planning for Economic and Social Failure, published in March 2023, and its finding that Natural England's advice regarding nutrient neutrality and water neutrality potentially reduce new housing supply by 43,000 units.
Answered by Baroness Scott of Bybrook - Parliamentary Under Secretary of State (Department for Levelling Up, Housing and Communities)
Nutrient pollution is an urgent problem for our freshwater habitats and rivers, many of which are internationally important for wildlife. While the government recognises the need to protect these habitats, and is taking steps to address the underlying pollution, it is important to acknowledge the significant burden nutrient neutrality has placed on housebuilders despite the limited impact extra wastewater from residents in new developments has on waterbodies.
As of March 2022, 74 local planning authorities have received advice from Natural England, issued in line with their statutory duties and relevant case law, across 27 catchments (equating to 14% of England's land area) which has effectively stalled housing development in these areas given the lack of available mitigation schemes, creating a major barrier to the government's ambition of delivering 300,000 homes per year by the mid-2020s.
That is why DLUHC have launched the Local Nutrient Mitigation Fund which will boost the supply of mitigation available locally, by funding high quality bids submitted by Local Authorities. This will complement the Natural England-led Nutrient Mitigation Scheme which is already delivering the first credits in the Tees Catchment. We are also placing an obligation on water companies to upgrade wastewater treatment works in affected catchments by 2030, stopping pollution at source and reducing the mitigation burden on development.
We are keeping further possible actions under review.

Question to the Department for Levelling Up, Housing & Communities:
To ask Her Majesty's Government what plans they have to require all new (1) homes, and (2) industrial and commercial buildings, to have sufficient solar panels to meet the energy demands of that building.
Answered by Lord Greenhalgh
The Government remains committed to meeting its target of net zero emissions by 2050 and recognises the important contribution that the energy efficiency of buildings has to make in meeting it. We must ensure that the energy efficiency standards we set through the Building Regulations for new homes put us on track to meet the 2050 target. From 2021, new homes will be expected to produce 31% less CO2 emissions compared to current standards, and from 2025, the Future Homes Standard will ensure that new homes produce at least 75% lower CO2 emissions compared to those built to current standards. We have also proposed an uplift in standards for new non-domestic buildings in 2021, and from 2025, the Future Buildings Standard will produce highly efficient non-domestic buildings which use low-carbon heat and have the best fabric standards possible.
The future is likely to see a mix of low carbon technologies used for heating and it is unlikely that there will be a one-size-fits all solution, so multiple technologies will play a role. We expect heat pumps will become the primary heating technology for new buildings under the Future Homes and Buildings Standards and that heat networks will also have an important role to play. There will also be a role, where appropriate, for other low-carbon technologies and renewable electricity generation such as solar photovoltaics.
The Building Regulations will continue to set a performance-based standard rather than mandating or banning the use of any technologies. This provides builders and developers with the flexibility to innovate and select the most practical and cost-effective solutions appropriate in any development. For example, many roofs are not suitable for solar photovoltaic panels because of the visual amenity, strength, or direction of the building.

Question to the Department for Levelling Up, Housing & Communities:
To ask Her Majesty's Government what assessment they have made of the case for requiring all new industrial and commercial buildings to include extensive solar panel coverage on their roofs.
Answered by Lord Bourne of Aberystwyth
The Building Regulations energy performance standards are deliberately couched in performance terms and do not prescribe the technologies, materials or fuels to be used, allowing builders the flexibility to innovate and select the most appropriate solutions for the circumstances. For example, many roofs are not suitable for solar photovoltaic (PV) panels because of building orientation, roof design, or over shading. We do, however, plan to consult on uplifting the energy efficiency standards of the building regulations in the coming months, including those for new non-domestic buildings.
