Decision times can't be measured here — West Sussex doesn't publish both a received and a decision date on enough records. The nationwide range across councils that do is 31 to 299 days.

What West Sussex 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 West Sussex actually provides each one, across all 163 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 West Sussex actually fill in?" and get these same numbers back. How to connect →
