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.

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 signed to XAdES. 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
XAdES signing, the standard the VCA's guidance points to, applied automatically with your company's electronic seal.
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. Your signing key stays on your PC; 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

Data & security
Data & security

- 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

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 to the company, like an electronic company stamp, that the software uses to seal each file. The VCA reject files without one. You load it into CoC AutoDocs once per PC; a test key is built in for the VCA test system.
Where does our data go?
Your signing key stays on your PC, stored in the browser so it can't be read back out — not even by us. 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 to the XAdES standard their guidance points to. 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: every plan includes unlimited users and PCs, and every company keeps its own history.

- One audit trail per companyWho made each file, when, and its status with the VCA. Export the lot for a CoP check in one click.
- Word template mapping done for youSend us the certificate you use today. Drop it in, and the form fills itself — one file or a whole batch.
Ready before the deadline, not after it.
Set up the company, add your models, make your first file. Most bodybuilders are done the same afternoon, well before the deadline.
