RSS Feed: Neil Blumfield has kindly set up an RSS feed based on this site, the URL for which is http://feed43.com/british-rpg-convention-list.xml. I should say that I've not tried this out myself, especially since this page changed its URL.
Calendar File Form: Roger Bell West has set up a site which converts this page to standard calendar file format, and updates that file periodically. See http://firedrake.org/infobot/ics/conventions.ics for this. Or - I'm told that by using webcal://firedrake.org/infobot/ics/conventions.ics instead, you should be able to "subscribe" to this calendar. Again, I haven't looked at this since this page changed URL.
