idea or feedback? not sure...
I think a separate faq under joining and switching “Switch your gas supplier to an existing account”
e.g. “If we already supply your electricity but not your gas here is what you need to do to add your gas supplier etc. etc.
And typing the words add gas into wattbot should bring up a bespoke dialogue?
Apologies if this is buried elsewhere already but it isn’t easy to find if so.
