Podcast Episode #16: Material Matters, Cut and Fill
May 5, 2026
Explore how early cut and fill strategy, sequencing and on‑site material management shape cost, programme and environmental outcomes on development projects.
Podcast Episode #11: Planning and Infrastructure Bill, are EPDs the key?
Explore nutrient neutrality, EDPs, the Planning & Infrastructure Bill, legal timelines, mitigation challenges and how we help unlock housing delivery across England and Wales.
Nutrient neutrality continues to affect planning decisions and housing delivery across England and Wales. In our latest podcast episode, Planning and Infrastructure Bill: Are EDPs the Key?, our host Ben Wakeling is joined by Brookbanks specialist Dean Swann and Mark Harris from the Home Builders Federation Wales to unpack the issue, the legislation behind it, and the future role of Environmental Delivery Plans (EDPs).
What Nutrient Neutrality Is, and Why It Matters
Nutrient neutrality prevents additional nitrogen and phosphorus from entering protected water bodies. Excess nutrients drive algal blooms and eutrophication, harming sensitive habitats. Though a planning issue since 2019, it stems from the Dutch Case (2018) and remains enforced via the Habitats Regulations.
Most loading comes from agriculture and the water industry, not new housing.
Even at significant build‑out rates, new homes contribute around 0.5%, falling to 0.07% when LURA 2023 measures are applied, yet housing cannot proceed without fully mitigating its share.
How Planning Decisions Are Impacted
LPAs cannot lawfully approve development that worsens conditions in failing catchments (targets set by the Environment Agency (EA) and Natural Resources Wales (NRW)). Applicants therefore need evidence‑based mitigation to demonstrate neutrality.
Mitigation remains challenging: credits are scarce and geographically limited; on‑site measures reduce but don’t remove impact; developers cannot influence the largest contributors directly. Result: stalled permissions and delayed delivery.
Are EDPs the Solution?
The Planning & Infrastructure Bill proposes Environmental Delivery Plans as a strategic route: developers would calculate impact, fund the EDP and, in principle, be deemed to have met requirements so development can proceed. Natural England has indicated EDPs for 16 nutrient areas in England, with activity stepping through winter 2025 and spring/summer 2026 (stakeholder engagement, guidance, user testing, consultations and secondary legislation).
Timelines feel ambitious, and EDPs apply to England only, with no equivalent route in Wales. It’s also unclear whether levy funds will keep pace with housing demand in each catchment.
How we support clients
Whether EDPs arrive next month or next year, success will still depend on accurately measuring and reducing impact, then submitting clear, robust evidence. As one team of experts, we help by:
- Calculating nutrient impacts and identifying reduction opportunities
- Preparing strong submissions for LPAs, Natural England and NRW
- Navigating conditions, approvals and appeals
- Aligning today’s approach with the emerging EDP framework
Our experience across planning, environmental assessment and infrastructure delivery means we can guide projects through complexity with clarity and confidence.

Mitigating the Impact of Global Uncertainty
April 30, 2026
Rising geopolitical tension does not affect development viability in isolation, but through increasing pressure on energy prices, supply chains and the cost of energy‑intensive materials. Where schemes are progressed on assumptions made under more stable conditions, these pressures can quickly challenge margins, appraisals and deliverability, particularly in a flat housing market. Our article looks at how developers can respond to build cost volatility in a more informed and proportionate way. Drawing on our specialists' experience, it explores how early coordination, design‑led value engineering and integrated decision‑making can help manage cost risk, protect scheme viability and avoid short‑term measures that compromise long‑term quality and value.
Our April 2026 Newsletter
April 27, 2026
Welcome to our April 2026 newsletter. In this month's Brookbanks newsletter, learn more about how high-rise developments can be made more deliverable, with guidance on how you can reduce risk and protect viability. We're also looking back on our April webinar, where Annabel Le Lohe and Katherine Peers gave a rundown of Environmental Impact Assessments and how coordination can make a real impact on project delivery. Plus, there's a recap of this month's podcasts featuring two special guests. Paul Smith, Managing Director at The Strategic Land Group, and Tom Park, Associate Development Director at Caddick Developments. Also, find out which members of our team will be at UKREiiF as well as more about the CPD event we're co-hosting with the LPDF in May.
