The product

From upload to certificate, one live case file.

The interface keeps complex operational work easy to follow. Each screen gives the user enough context to make the next decision without losing the wider history of the case.

01

The problem

EPVS needed a reliable way to handle each validation from upload to certificate.

A renewable-energy validation can involve contracts, detailed quotes, calculations, survey evidence, energy bills and other supporting documents. Without one reliable workflow, missing evidence and unclear ownership quickly become difficult to manage.

The existing systems and dependencies were ageing and did not provide the features, security or hosting quality the operation needed. The work was not simply to digitise a form. It was to create a dependable case-management process around every submission.

02

The approach

The portal gives installers and the EPVS team one shared place to work from.

Installers can create a validation, choose the product type, enter the customer and installation details, add relevant finance and insurance information, and upload the evidence needed for review.

The EPVS team works from the same record. They can see what was submitted, what is missing, who owns the validation, which status it is in and what has already been said or changed.

03

The workflow

Each validation behaves like a live case file, not a static submission.

A validation can hold customer details, installation data, product type, payment information, finance parties, insurance details, contract values, files, notes, tasks, status changes and activity history.

When evidence is incomplete, EPVS can request more information and the installer can respond against the same record. Compliance calls can be logged there too. Once the review is complete, the workflow can move through to certificate generation and delivery.

04

Why it matters

The software supports a clearer and more consistent validation operation.

ValidationHub connects submissions, evidence, decisions, customer checks and certification so the team has a dependable history of each case.

That makes the operation easier to understand and manage as work moves between installers and reviewers. The value is not a prettier admin screen. It is a controlled process the organisation can run properly.

Platform capability

Built to handle the work in one place.

ValidationHub combines the practical features needed to collect evidence, manage reviews and keep the wider operation connected.

  • Installer submissions

    A guided route for creating and supplying each installer case.

  • Product-specific evidence

    Different information and document paths for different products.

  • Customer and installation records

    The core details needed for a complete review.

  • Finance and broker details

    Relevant commercial parties recorded against the same case.

  • Insurance information

    Provider details kept alongside the validation evidence.

  • Contract and payment data

    Agreement values and payment information held in context.

  • Document collection

    Contracts, quotes, calculations and supporting files in one place.

  • Information requests

    Clear follow-up when the review needs more evidence.

  • Statuses and ownership

    Visible responsibility and progress across every validation.

  • Notes, tasks and history

    A practical trail of review work, decisions and follow-up.

  • Compliance call records

    Customer checks logged against the validation they relate to.

  • Certificate generation

    Approved cases can produce the final validation certificate.

  • Certificate delivery

    Completed documents can be sent through the same workflow.

  • Operational reporting

    Charges, statements and reporting connected to the case process.

  • Xero and 8x8 connections

    Finance and call activity linked into the wider operation.

The outcome

The numbers behind the ValidationHub workflow.

The useful result was not simply a new interface. It was a connected operation that could handle more work, reduce repetitive admin and keep evidence, decisions and finance linked together.

43% increase

More validations processed

More validations could move through the operation because submissions, review, queries and certificates were handled in one controlled system.

68 hours saved

Less finance administration

Connecting validation charges, statements and invoices to Xero reduced repetitive accounting work.

27% increase

More installer reviews collected

The wider workflow made it easier to capture installer reviews as part of the validation and customer evidence process.

£626,535,374

Contract value validated and audited

The total contract value of validated and audited uploads handled through the workflow as of 11 January 2026.
