PPP Expiry DiPPA
Secure the Handback. Manage PFI Expiry.
What is it?
A secure, ring-fenced bank account designed to manage the financial risks of expiring PFI, PPP, LIFT, MiM and similar contracts.
Who is it for?
Public Sector Authorities, Special Purpose Vehicles (SPVs), and Infrastructure Lenders & Investors.
Why do I need it?
As contracts expire, disputes over asset condition can lead to funding gridlock. Contracts often mandate a "Retention Fund Account" to hold deductions for defects, but public sector bodies cannot easily open joint accounts, and SPVs are restricted by lender security packages. You need a neutral, secure pot to ensure rectification funds are protected and available.
Meanwhile, our standard DiPPA is perfect for new projects delivered under a PPP or successor contract.
What are the benefits?
Retention Fund Compliance
Simplifies the opening and management of a secure "Retention Fund Account" or "Sinking Fund" as required by SoPC4 and NISTA guidance.
Rectification Assurance
Funds for repairs are ring-fenced from the SPV’s operating cash flow and paid directly to the supply chain. This guarantees the money is used for the asset, not leaked to shareholders.
Dispute Reduction
Acts as a neutral holding account for disputed funds or shared survey costs. Independent surveyors and contractors are paid directly, reducing payment-related disputes.
Intelligent Transparency
Provides a real-time, "Open Book" view of lifecycle spending and sinking fund balances, allowing Authorities to audit compliance instantly without manual data requests.
How does it work?
- We enable you quickly to open a ring-fenced DiPPA for the project.
- Deductions from the Unitary Charge or Lifecycle contributions are deposited into the DiPPA and held in trust.
- The Authority and SPV have real-time visibility of the fund balance, and payment oversight via the digital flow of payment authority in a DiPPA.
- Funds are released directly to the supply chain to pay for rectification works as they are completed.
What does it cost?
Simple and Transparent.
A standard transaction fee of 0.25% of the payment value.
