Not an expert but depends on your lights is my understanding.
Best way to be sure - at night time find a flat wall or similar, point the car directly at it and put the headlights on. If the shape of the light is flat at the top, then your lights don't need changing. If the shape of the light is higher on the left side then they're designed for UK roads and need to be changed for EU.
How you change them I dunno, you can get stick on deflectors but if you're going to move permanently I'd suggest replacing the interior deflector mirrors in the headlamps with RH drive ones.
