Taxes and cost of living are higher in Denmark, but it's still more than double what a student in Britain gets. I had friends studying in both countries, and I was shocked when I found out the difference. (It was all science research.)
A couple of years ago, I saw a job advert at a British research institute I was working with. It was a PhD position, funded and managed by Copenhagen University, but living and working mostly in England to use the special equipment the institution had. The salary was higher than a senior researcher position, also listed, and higher than all the developers I was working with.

Due to COVID, the University is also trying every trick in the book to further reduce any funding and increase costs where possible, due to the lack of foreign student income. That's all good and well, but there's only so far a person can go.
Fun!
