About these figures

How are decision times measured?
Days from the date the council validated the application to the date it decided it, for applications approved or refused in the window. That is the clock councils report against and the official statistics use. Each council’s page also shows the count from receipt, which is what the applicant actually waited. Withdrawn and undecided applications are not timed.
Why do these figures differ from the council’s own?
Councils count an agreed extension of time as decided on time; we treat the calendar as the calendar. Our figures are also live and rolling, where official statistics are quarterly and annual. So a council’s own within-eight-weeks figure will usually sit a little above ours.
What counts as approved?
Approval rate is approvals divided by approvals plus refusals. Withdrawals, and decisions whose outcome the register does not state, are counted in the totals but not in the rate.
Why is a council missing?
A council is published when it has at least 25 timed decisions in the window and its register’s decision data passes our consistency checks. Councils that fail are listed with the reason rather than shown with a number that would mislead.
How often is this updated?
Nightly, from the decisions we collect from every council register we monitor. The window is the twelve months to the last complete month.
