Signed eCoC files, done in two minutes a vehicle.
The VCA needs a signed IVI XML file for every M, N and O vehicle you complete. CoC AutoDocs turns that into a short form your office fills in, then checks, signs and saves the file, ready to upload.
Does your vehicle need an eCoC?
Three questions. Based on the VCA's published guidance for the 29 November 2026 change.
A plain-English summary of the VCA's published guidance, not legal advice. Acceptance is always the VCA's decision.
What changes for your office
Same certificate, same information. A completely different amount of fuss.
BY HANDThe manual VCA portal route
- 30 to 45 minutes per vehicleHand-building the XML, or converting and editing it in a text editor.
- No check until you uploadThe VCA rejects on submission and you rework the file offline.
- A separate signing toolExtra licence, extra steps, every file.
- Corrections by handRe-edit the raw XML with no record of what changed or who changed it.
- Records in spreadsheetsSomewhere on a shared drive, if anyone remembered.
WITH COC AUTODOCSThe same job, done properly

- Checked before the file existsAgainst the VCA's own schema, with the wrong box named in plain English.
- Sealed in your company's nameThe seal is included, in the format the VCA portal accepts. Test key built in for the VCA test system.
- Corrections with version numbersFix, reissue, old file marked superseded, the way the VCA expects.

Build sheet to VCA portal, four steps
Set up once
Company details and your vehicle models: type, variant, version, body code and your usual wording.
Enter the vehicle
Pick the model. Type the VIN and the numbers from the build sheet, or drop a mapped Word certificate.
Check and sign
Validated against the VCA schema, then digitally signed. Errors are named before anything is made.
Upload to the VCA
Save the file, upload it through the VCA portal under your own account, mark it accepted.
Everything the VCA asks for. Nothing you don't need.
UK IVI XML generation
Built to the VCA's published UK IVI 2.0 schema, with GB and UKNI approval authority codes and the correct scheme.
Digital signatures
A standard XML digital signature, the format the VCA portal accepts, with your company's electronic seal included.
Validation before submission
Field lengths, code lists, dates, VIN format and axle-mass arithmetic all checked before a file exists.
Multi-stage support
Built for stage 2 bodybuilders. Your stage goes in; the base vehicle's data doesn't need to, per the VCA's own guidance.
Audit trail and CoP
Who made each file and when, its status with the VCA, and versioned corrections. Export the history as a spreadsheet.
Hosted in the EU
Nothing to install. The seal is held for you in the provider's certified hardware; your files and history live in an EU data centre.
Built on the rules that apply to you.
Every file CoC AutoDocs makes follows the GB and UKNI type-approval framework and the VCA's own eCoC specification.
GB & UKNI type approval
GB & UKNI type approval
- Road Vehicles (Approval) Regulations 2020 — the GB type-approval scheme: GB unlimited, medium and national small series
- Assimilated Regulation (EU) 2018/858 — the type-approval framework as it applies in Great Britain; Regulation (EU) 2018/858 continues to apply to UKNI approvals
- Assimilated Regulation (EU) 2020/683 — the Certificate of Conformity content and format the file carries
- Assimilated Regulation (EU) No 1230/2012 — masses and dimensions, the numbers the form checks before a file exists
Standards & formats
Standards & formats
- VCA UK IVI 2.0 XML schema — the eCoC format the VCA portal accepts; every file is validated against it before it is made
- W3C XML Signature (XMLDSig) — the signature format the VCA portal accepts; XAdES, the EU form, is ready for when the VCA switch it on
- UK eIDAS electronic seals — every file carries a seal in your company's name from a provider on the UK trusted list
- Multi-stage approval — stage 2 files carry your stage's data and reference the base vehicle, per the VCA's guidance
Data & security
Data & security
- UK GDPR and the Data Protection Act 2018 — we hold only what running the service needs: your team's work email addresses, the signatory named on your certificates, and the director's details the seal provider verifies
- Nobody handles a private key — the seal's key is made and kept in the provider's certified hardware and never leaves it, so neither you nor we can copy it. A certificate of your own, if you use one, stays in your browser and never reaches us
- Hosted in the EU — your files and history are stored in an EU data centre, never outside it
- Encrypted in transit — every connection to the app runs over TLS
- No third-party submission — you upload under your own VCA portal login; we never hold your VCA credentials
Regulations named as they apply in Great Britain and Northern Ireland. Checked against the VCA's published schema; acceptance is always the VCA's decision.

Straight answers
Do we actually have to do this?
If your approval is GB unlimited or GB medium series, yes, for every M, N or O vehicle built from 29 November 2026. National small series approvals are exempt. Vehicles built before 29 November don't need one, even if registered later.
What's the digital signature? We just sign the paper one.
A certificate issued in the company's name, like an electronic company stamp, that seals each file. The VCA reject files without one. With CoC AutoDocs the seal is included: we hold it for you with a provider on the UK trusted list, so there is nothing to buy, install or renew. A test key is built in for the VCA test system while your company is being verified.
Where does our data go?
Nobody handles a private key: the seal's key is made and kept in the provider's certified hardware and never leaves it. The files you make and your history are stored in an EU data centre, encrypted in transit, and only your team can see them. You upload to the VCA yourself, under your own login.
Can you submit for us?
No, and neither can anyone else: the VCA don't allow third parties to submit on a manufacturer's behalf. You upload under your own portal login, which takes a minute for a batch.
Is this "VCA approved"?
The VCA don't approve software. CoC AutoDocs's files are checked against the VCA's published schema before they're made and signed in the format the VCA portal accepts. Acceptance is always the VCA's decision.
Built for more than one site.
Several depots, a dealer group, or an office that makes files for other builders: one account covers them all, and every company keeps its own history.
