from what i understand there is no such thing as illegal firing modes according to UK law. paintball guns are classed as toys (this does not mean they are, and you should never use them anywhere other than a paintball site.). full auto is just banned by tourney's and sites because it can be dangerous and can be unfair to players who don't have it. you would be fine with the e grip as long as you set it to semi.
the response trigger from what i understand basically uses excess gas to push the trigger forward after you have pulled it. this enables you to shoot faster because you aren't waiting as long for the trigger to be reset.
the best thing to do would be to call your local walk on site and find out what their rules regarding e grips and response triggers are.
