What Gwynedd actually fills in

A "field" is one piece of information on an application — the decision date, the applicant's name, the address. Councils fill these in inconsistently, so this table measures how often Gwynedd actually provides each one, across all 3,241 records. Anything listed as reliable you can count on; anything lower, check the council's own record before relying on it.

Once this data is connected to ChatGPT or Claude you can just ask "what information does Gwynedd actually fill in?" and get these same numbers back. How to connect →
