Greets!
It's not your clutch that's on the way out. I had this EXACT same problem until I had my car serviced and they did NOT change the clutch. On the Renault service sheet there's a check box relating to clutch judder and they check this during a service. Now my car pulls away silky smooth so my guess would be that there is something that can be adjusted or tweaked as the clutch wears with age.
Also, it could be that your spark plugs need replacing (taken from the Haynes service manual for the Clio MK2). This could explain why it's worse when cold. Side note - I had new spark plugs included within the service.
