After Brexit the tuition even for Europeans increased from 10K£ pounds a year to 40K£. A thousand pounds will not change much. It does of course change the kind of people they can admit from abroad, but it seems that the UK has a lot of demand. When I did an Erasmus MSc funded by the EU, I was the only European in the whole cohort. Many peers explicitly told me that they applied to get a chance to stay in Europe after they graduated. Most did.
