We are moving to France in the autumn: please can anyone explain how to get a European Certificate of Conformity for a Roomster so that we can register it there?

A COC (Certificate of Conformity) is a declaration of the conformity with the type approval of EC. The purpose of this document is to ensure the free movement of goods within the European Union, specifically for those goods that are subject to homologation and registration.

A COC is a producer’s declaration that the vehicle complies with the given approved type. This document contains information about the vehicle and its producer’s identification, type approval number, technical specifications and other data. The content of a COC is defined by EU regulation (Amendment IX, Regulation 92/53). Vehicles without the EU specification (e.g. vehicle manufactured for the U.S. or Japanese market) and older vehicles that have not been given the type approval of the EC yet, do not have an existing COC. Similarly, it is not possible to issue a COC for converted vehicles. A COC is only obtainable for passenger vehicles, motorcycles and tractors.

Thank you, Etos, that's exactly what I'm after. But how do you go about actually getting hold of one please?

I suggest you contact Skoda UK - IIRC, VW and Skoda charge a £10 admin fee provided a certificate has not already been issued. If you are requesting a duplicate, then it is something like £85.
