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.
Webinar Summary: Section 106 Contributions: Purpose & Recovery
Section 106 (S106) agreements play a vital role in shaping sustainable communities by ensuring that developments contribute to essential infrastructure and services. However, recent research highlights a growing challenge: billions of pounds in developer contributions remain unspent by local authorities. At Brookbanks, we believe understanding the purpose of these agreements, and how to recover unspent funds, is critical for developers and stakeholders alike.
What Are Section 106 Agreements?
Grounded in the Town and Country Planning Act 1990, S106 agreements are legal obligations designed to mitigate the impact of development. They must be:
- Necessary to make the development acceptable in planning terms
- Directly related to the development
- Fairly and reasonably related in scale and kind
Typically, these agreements cover contributions for highways, education, affordable housing, and community facilities. They are binding on the land and can be modified or discharged under certain conditions.
The Scale of Unspent Contributions
According to recent Home Builders Federation (HBF) research, local authorities in England and Wales are holding over £8 billion of infrastructure payments by developers, including more than £6 billion from S106 agreements and nearly £2 billion from the Community Infrastructure Levy (CIL). Alarmingly, only £20.6 million has been returned to developers in the last five years
.
Why Are Funds Sitting Idle?
Several factors contribute to this issue:
- Limited resources within local authorities to manage and deliver projects
- Delays caused by procurement or political changes
- Poor tracking of obligations across departments
- Narrow or outdated specifications in agreements
- Risk-averse spending approaches
Why Aren’t Developers Claiming?
For many developers, recovery of unspent contributions is not a priority. Reasons include:
- Focus on future developments rather than historic agreements
- Lack of robust documentation and payment records
- Desire for contributions to be used as intended
- Concerns about straining relationships with local authorities
The Benefits of Recovery
Actively pursuing unspent contributions offers significant advantages:
- Improved cash flow and financial flexibility
- Enhanced margins and reinvestment opportunities
- Stronger stakeholder confidence and proactive financial management
- Encourages local authorities to use future contributions effectively
Practical Next Steps for Developers
To maximise recovery opportunities:
- Locate and review all signed S106 agreements
- Note key dates and repayment deadlines
- Create a schedule of contributions made and due
- Submit requests to local planning authorities
- Engage collaboratively with LPAs
How Brookbanks Can Help
We’ve launched a dedicated Section 106 recovery service to support developers in reclaiming unspent contributions. Our team will:
- Review all agreements and identify funds eligible for repayment
- Liaise with developers to prioritise recovery
- Work collaboratively with local authorities to ensure successful outcomes

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.

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.
