Is there a company that it’s possible to rent a car from in France but drop off in England?

My fiancee and I have the idea to travel to England from France by hire car as we have a lot of luggage and want to do something different besides flying. Maybe there is a company that deals in one way rentals between England and France??

where can I find cheap car hire in Barcelona but I want to drop off in France?

I am looking to pick up in Barcelona and drop of in Bergerac or Bordaux. Does any body know how I ca do this cheaply?
