That's interesting. Looking at Michael Chinery's insects of Britain and Western Europe it says that the nymphs of most Froghopper species live in froth and are also known as spittle bugs and cuckoo-spit insects.
Your identification is for the Common Froghopper. I just wasn't sure so thank you very much for your help.
