As Redtop said. If you are really worried I would just take it on the ferry from Esbjerg to Harwich near London. I know its still a fair drive to Esbjerg since its on the western coast of Denmark but its still a hell of a lot shorter than driving all the way to the UK.
If you don't want to take the ferry then with all honesty, I would just give the car a thorough inspection (belts, tensioners, leaks etc.) and if everything looks good; then drive it over. With all honesty, you would be pretty unlucky for that occur and it probably is unlikely anything will seriously go wrong.
Though in saying that; it definitely needs changing soon
