The docs get despatched today (means posted or emailed so not sure when I'll get them) and it will say how you can pay. I'm in SW as well. They won't help here.
If the docs don't arrive soon enough you can contact Computershare- do login/register (don't worry about last step on posted verification code) - you then get access to ALG docs - download etc
