As a Scotsman, it is my duty to say "England" is not interchangeable with "UK". Even in the published piece from Educational Testing Services the term *actually* used is "England / Northern Ireland". While Nothern Ireland is a part of the UK, calling it out alongside England only adds to the slight. The possibly non-existent / mythical Scotland and Wales are many times larger than Northern Ireland but clearly down't merit a mention. Scotland hardly has any tech workers anyway, just little things like Grand Theft Auto are made here, no biggie.
I'm calling the United States "California" from now on.
"Hi, I'm Andy from New York"
"Oh, a Californian, how exotic. Welcome to Scotland!"
