It's done a bit differently, but there's an app on phones "The English Dialects app" you can install that will give you some specific features and how they distribute in Britain and Ireland. It will also try to guess where you're from, if you're from those parts.

It does heat maps of features, rather than trying to group bundles into discrete areas. This is probably more accurate, because it shows you were features are strong. Sometimes they'll correlate with others, sometimes not.
