Years ago in the UK you had to take your new vehicle back to the dealer. If you bought the new vehicle from Renault in York and a service was due and you happened to be in in London, then you had to take it to a Renault dealer in that area. That has been stopped. Now if you bought your new Renault in York and a service is due, then you can take it to any garage and they have to use genuine Renault parts to keep the warranty/service schedule valid. Same applies to any manufacturer, although I wouldn't like my Maserati worked on by just any old place, so I would take that to a Maserati dealer or specialist. I am Renault trained, but specialised in the older Volvos until 2007 when arthritis took over and kinda stopped me from spannering.
