eCoC EU² versus the Manual VCA Portal: the Real Time and Cost Savings of eCoC Automation
Two routes to meeting the eCoC mandate
Once eCoC goes live, every M, N and O category vehicle requires a digitally signed eCoC lodged with the VCA before it can be registered. You can get there in one of two ways: handle it manually through the VCA portal, or automate the entire pipeline with eCoC EU² software.
On the face of it the manual route looks like it costs nothing. In reality it turns out to be the dearest option once you tot up the engineering hours spent assembling IVI XML, the rejections you can only resolve offline, the standalone e-signing licence and the spreadsheet keying behind every certificate. This article sets the two approaches against each other.
The submission process, stage by stage
Both routes pass through the same six stages. What sets them apart is how much of each stage runs automatically and how much falls on a person.
Prepare the data
Type approval, VIN and technical data are gathered for each vehicle.
Build the XML
The data is shaped to the IVI 2.0 schema and checked for completeness.
Digital signature
The finished XML is digitally signed to EU / UK standards.
Submit to the VCA
The eCoC is sent to the IVI National Access Point (the VCA gateway).
Validation
The NAP checks the submission against the UK IVI schema and reports back.
Registration
A valid eCoC is registered nationally, allowing the vehicle to be registered with the DVLA.
eCoC EU² automates stages 1 through 4 from start to finish and presents the stage 5 feedback in plain language. Handle it manually and each stage becomes its own tool with a manual hand-off in between.
eCoC EU² and the manual VCA portal, side by side
| Capability | e2eCoC EU2 | Manual VCA portal |
|---|---|---|
| Time to file | Minutes for a whole batch: generate, validate, sign and submit in one pass. | 30 to 45 minutes per certificate, one vehicle at a time. |
| IVI XML preparation | Valid IVI 2.0 XML generated automatically with the correct GB and UK(NI) approval authority codes. | Hand-configure the XML, or run a EUCARIS conversion tool, then edit the GB / UK(NI) references by hand in hard-to-read raw files. |
| Pre-submission validation | Built-in schema validation catches errors and guides you to the correct values before anything is sent. Incorrectly completed eCoCs are never transmitted, which prevents rejections at VCA level. Every error is caught before submission, and the wrong fields are highlighted in an easy-to-read interface so they are quick to spot and fix. | No pre-check. The VCA rejects on submission, the portal offers no in-place fix, and you reconfigure the file offline and resubmit. |
| Vehicle data entry | Automatic import of vehicle data from a VIN lookup. | Manual spreadsheet management: copy and paste data for every vehicle. |
| Edits and corrections | Fully editable records with a complete, timestamped audit trail. | Re-edit the raw XML by hand, with no audit trail of what changed or who changed it. |
| Digital signing | Seamless integrated XAdES signing as part of the flow. | A separate e-signing platform at additional licence cost and extra manual steps. |
| Cross-jurisdictional submission | Integrated with EU National Access Points for vehicles exported to the EU. | A separate manual process and a different portal for each country. |
| Audit trail and CoP compliance | Full traceable history for every certificate, ready for Conformity of Production checks. | Manual record-keeping in spreadsheets and shared drives. |
| Scalability | Bulk processing for high-volume production lines. | One certificate at a time; throughput is limited by people. |
| Cost of errors | Minimal. Most errors are caught before submission. | Each rejection means offline rework and a registration delay for that vehicle. |
The hidden costs of going manual
VIN lookup instead of spreadsheets
eCoC EU² draws vehicle data automatically from a VIN lookup. Doing it manually means copying and pasting out of Excel — slow work, and the biggest single source of the data-entry errors that the VCA later bounces back.
Validate up front, not afterwards
The VCA portal only validates on submission and then rejects the entire file, with no editor inside the portal. eCoC EU² checks against the IVI schema first, letting you resolve problems before they turn into a rejection and a hold-up.
XML you never have to handle
The manual approach means either editing IVI XML by hand or running a conversion tool — including those EUCARIS points to — and then fixing the GB / UK(NI) references yourself. eCoC EU² turns out correct, signed XML without anyone ever reading a tag.
Exporting into the EU
Export vehicles into the EU and you also have to file with other Member States. Because eCoC EU² is integrated with EU National Access Points, cross-jurisdictional submission is a single workflow rather than one portal per country.
Try it on your own vehicles
The quickest way to weigh up the difference is to put a few of your own VINs through eCoC EU² and watch each eCoC generate, validate and sign within minutes.
