BV-001 / Protected Payment Infrastructure

Protected deposits.
Trusted projects.

02 / ProblemThe trust deficitDIAG.001

A £40bn industry runs on goodwill — and breaks because of it.

Home improvement payments still move through bank transfers and credit cards designed for retail. Neither protects either side of the table. The result: a structural mistrust that costs both parties billions.

Pays inHomeowner
  • H.01Deposit fraud

    Funds vanish before work begins. No recovery path.

  • H.02Contractor abandonment

    Half-built sites. Sunk capital. No legal leverage.

  • H.03Budget uncertainty

    Scope creep, surprise invoices, opaque draws.

  • C.01Late or partial payment

    Cash flow stalls when homeowners delay or contest.

  • C.02Verification limbo

    Completed work waits weeks for sign-off.

  • C.03Cash flow pressure

    Materials and crews funded on personal credit.

03 / SystemHow BuildVault worksSCHEMATIC.04

Four steps. One protected flow.

Every BuildVault project moves through the same four-stage protocol. Each stage is independently verifiable and recorded to an audit-grade ledger.

01VAULT.DEPOSIT

Secure deposit vault

Homeowner deposits the full project budget into a regulated holding account. Funds are ring-fenced, never touched by BuildVault, never accessible to either party.

  • Regulated PSP custody
  • FSCS-compatible structure
  • Per-project ring-fence
02MILESTONE.VERIFY

Verified milestones

Project is broken into milestones at contract signing. Contractor submits proof of completion. Homeowner approves — or independent inspector verifies in dispute scenarios.

  • Photo / doc evidence
  • Two-party sign-off
  • Optional 3rd-party inspector
03RELEASE.AUTO

Automated releases

On verification, the milestone tranche releases to the contractor automatically. Payout settles in hours, not weeks. The vault recalculates remaining balance in real time.

  • T+0 instant settlement
  • Programmatic release rules
  • Audit-grade ledger
04DISPUTE.SHIELD

Dispute protection

Structured resolution framework: clarify, mediate, escalate. Funds stay protected throughout. Both parties get a clear path forward — no court, no chargebacks.

  • 48h response window
  • Independent mediation panel
  • Binding outcome on-platform
04 / ComparisonWhy the status quo failsSPEC.TABLE

Every alternative was built for a different problem.

The instruments homeowners and contractors currently rely on were designed for retail, e-commerce, or one-off legal escrow — not for staged, milestone-driven construction work.

A multi-billion £ industry with virtually no native payment infrastructure.

The UK home improvement market processes tens of billions annually. The vast majority moves through instruments built for retail or generic banking — leaving an open lane for purpose-built protection.

07 / Trust layerRegulatory architectureCOMPLIANCE.01

A reinforced foundation, not a wrapper.

BuildVault is engineered around the regulatory reality of consumer payments and construction. Compliance is structural — not retrofitted.

FIG.07 · REINFORCED FOUNDATIONTRUST LOADFCA · PSP · KYC
REG.01

PSP-backed custody

Funds held with FCA-authorised payment partners. Never on BuildVault's balance sheet.

REG.02

KYC / AML by default

Identity verification on every party. PEP and sanctions screening at onboarding and on-going.

REG.03

Consumer-rights aligned

Built around UK consumer-protection norms and Section 75-style assurances.

REG.04

Audit-grade ledger

Every movement timestamped, signed, and exportable. Designed for regulatory disclosure.

08 / EcosystemPartnership networkNET.MAP

BuildVault sits at the centre of the construction-payments stack.

A protocol layer for protected payments — interoperable with PSPs, insurers, regulators, and trade bodies. The trust fabric for an entire industry.
