How REGREP Works

a common regulatory data foundation

REGREP is a regulatory reporting infrastructure platform designed to help financial institutions operationalise regulatory reporting obligations in a structured, repeatable, and audit-ready way.

Rather than treating each regulation or report as a standalone exercise, REGREP focuses on building a common regulatory data foundation that can be reused across multiple frameworks, jurisdictions, and reporting cycles.

This page explains how REGREP fits into existing systems and how regulatory reporting is handled end-to-end.

The REGREP Approach

REGREP follows a simple principle:

Separate regulatory logic from operational systems, and manage reporting through structured data.

Most regulatory reporting challenges arise because regulatory requirements are implemented directly on top of finance, risk, or operational systems.

REGREP introduces a dedicated reporting layer that sits between source systems and supervisory submissions.

This allows firms to respond to regulatory change without repeatedly re-engineering upstream systems.

Step 1: Data Ingestion & Normalisation

REGREP connects to existing data sources, including:

  • Finance and accounting systems

  • Risk and capital calculation systems

  • Transaction processing platforms

  • Third-party data providers

Incoming data is ingested and normalised into a structured regulatory data model. This process ensures consistency across entities, reporting periods, and jurisdictions.

REGREP does not replace source systems. It standardises regulatory data for reporting purposes.

Step 2: Regulatory Data Management

Once ingested, data is managed within REGREP’s regulatory reporting layer, where it can be:

  • Mapped to regulatory concepts and templates

  • Enriched with reference and entity data

  • Versioned and traced over time

  • Reused across multiple regulatory frameworks

This approach reduces duplication and ensures that the same underlying data is used consistently across reports.

Step 3: Validation & Control

REGREP applies regulatory-grade validation controls aligned with applicable technical standards, including:

  • Structural and technical validations

  • Framework-specific validation rules

  • Cross-report consistency checks

Validation results are transparent and traceable, allowing reporting teams to identify issues early and resolve them before submission.

REGREP supports pre-submission confidence, not post-submission remediation.

Step 4: Reporting & Output Generation

REGREP generates supervisory-ready reporting outputs in the formats required by each framework, including:

Outputs are produced from the same validated data foundation, ensuring consistency across reporting obligations.

Step 5: Auditability & Change Management

REGREP maintains full traceability between:
  • Source data
  • Regulatory transformations
  • Validation results
  • Final reporting outputs
This supports:
  • Internal audit
  • External audit
  • Supervisory enquiries
  • Regulatory change analysis
When regulations or technical standards change, updates are applied at the reporting layer rather than across multiple systems.

How REGREP Supports Multiple Regulations

REGREP is designed to support multiple regulatory frameworks in parallel, including EU, UK, and international regimes.

A single regulatory data foundation can support:

This reduces fragmentation and allows firms to scale reporting capabilities as new obligations emerge.

Integration & Deployment

REGREP is delivered as a secure, cloud-based platform and integrates with existing systems through APIs and standard data interfaces.

Key characteristics include:

  • Modular, capability-based architecture

  • Integration-first design

  • Support for multi-entity and group reporting

  • Alignment with enterprise security and data governance requirements

REGREP can be adopted incrementally, starting with a single framework or reporting obligation and expanding over time.

What REGREP Is and Is Not

REGREP is:

  • Regulatory reporting infrastructure

  • A data-driven reporting platform

  • A foundation for repeatable supervisory reporting

REGREP is not:

  • A compliance certification tool

  • A regulatory advisory service

  • A replacement for governance or risk ownership

REGREP supports how reporting is implemented, not what decisions firms must make.
