In the West Country we always called them baked potatoes. Then the word "jacket" started to creep into the vocabulary somewhere around the late 70's.
I'm not sure if the word was imported from America or was adopted from another region of the UK. Or perhaps it was the result of a marketing ploy by someone invested in potatoes.
At first we weren't sure exactly what it meant but certainly by the mid 80's it had become common parlance amongst younger people.
Most people my age and older (I'm 67) still refer to it as a baked potato but would use the word "jacket" if ordering in a restaurant or speaking to someone younger because otherwise it causes confusion.
They are sold as "baking potatoes" and I consider this to be the correct word.
