The statutory time limits are 8 weeks for most applications, 13 weeks for major development and 16 weeks where an Environmental Impact Assessment applies, under article 34 of the Development Management Procedure Order 2015. Government policy adds that no application should spend more than a year with decision makers, including any appeal.

Decisions
Approved plus refused decisions published on the council's planning register in the period shown. It counts what the register we read published, which can be less than everything the council handled.
Approval rate
The share of decided applications that were approved. Withdrawn applications sit outside this number: withdrawing is the applicant's act, not the council's decision.
Median decision time
The middle application, measured in days from the date the register says the council received it to the date it decided it. Half were faster, half slower. Councils and applicants can lawfully agree more time, so elapsed days beyond a target are not automatically a breach of it.
Decided within 8 weeks
The share of dated decisions made within 56 days of the received date on the register. 8 weeks is the decision period most standard applications start with; agreed extensions can lawfully move it.
Withdrawn
Applications the applicant withdrew before a decision. Shown separately and never counted in the approval rate.

Do these figures match the council's official statistics?
Not exactly, and they are not meant to. These figures are computed from the planning register entries we hold for each council, refreshed continuously from the public registers. They describe published register data, not the council's official performance statistics, and coverage per council can differ from the register's own totals. Always confirm requirements for your own project with your council before applying. Official statistics also count decisions made within an agreed extension of time as on time, so our elapsed-day figures can read slower than the official measure.
