Vehicle Overhaul Regulation 2019/621. It’s EU wide. Yes, you have to be a registered business and VAT registered.
I guess it came in post the Brexit vote but pre Brexit finalisation so never got implemented in the UK.
As long as I use Ducati OEM, or Ducati recommended, parts & fluids, complete a service request form, pay them €9.50 to process it, send them the work sheets and evidence of service, they accept it and update the service records for the bike, which for models since 2021 are all held centrally on their server now.
I also get access to all the latest workshop manuals - for another €9.50/hour.
NB, I believe, from reading the detailed blurb within the site, even franchised dealers have to pay the €9.50 to register a service.
