Other sites covering British comic characters:
www.comicsuk.co.uk - one of the best resources for information on UK comics, still growing fast.
The Superhero Store - www.superherostore.co.uk
Toonhound's Fleetway Street site.
Neither of the first two are great for in depth coverage of the heroes but they do cover some aspects of the comics most of them originally came from. Other information on the net is far more scattered and haphazard. Characters and titles that seem to have a good degree of coverage are (unsurprisingly) Dan Dare, 2000A.D. (but only some of the characters), and the later works of the more influential British writers (Alan Moore, Grant Morrison, Warren Ellis, etc.) that have been distributed by American publishing houses.
To make the list of heroes (and the odd villain) easier to navigate, I've split it into sections. In order to keep things at a manageable size, I've had to lay ground rules as to who does or doesn't qualify for entry. I'm not going to include any of the innumerable western or war comic strip heroes unless they have a "superheroic" twist to them; if I did include them this list would be endless. The same goes for literary adventurers and detectives - there are just too many of them, so unless they have a strong element of the fantastic to them, I've left them out (so no Miss Marple but yes to Sherlock Holmes who has been credited with some paranormal adventures).
