The Criteria for Top 10 British Horrors of the 90's was slightly different. First i had to find 10 i actually owned, then basically rank them in 1 - 10 order. That's basically it.
Ravenous (1999)
Event Horizon (1997)
Mary Shelley's Frankenstein (1994)
Dust Devil (1992)
The Wisdom of Crocodiles (1998)
Breeders (1997)
Darklands (1996)
Tale of a Vampire (1992)
Witchcraft X: Mistress of the Craft (1999)
Razor Blade Smile (1998)
Disclaimer. The first 4 are worthy contenders for any list, especially
Ravenous.
The next four are watchable enough but wouldn't be anywhere near contention in any other decade. The final two are woeful. Witchcraft X comes before Smile due to the massive breast quota.
