I wouldn't say that -- depends on where you go. I lived in the south of England, Brighton, for years and the Catholic churches I went to (there were two in the city limits and one outside) were all packed for all 4 to 11 masses each Sunday and sometimes on weekdays too). The Coptic Church in nearby Hove was also packed the one time I went there and I peeked in a Baptist church there and it was also packed.
The Catholic Churches in the north when I went on holidays were also more or less full in Edinburgh, Bristol, Cambridge etc.

A woman who is a native Edinburger told me that there are very few Catholics in Edinburgh and that most of the churches there are Presbyterian or Methodist. However, she left there many years ago to settle in the US.
