Decision outlook
Plota predicted a decision around 14 Sept 2026; it is now day 107.
Day 107, past the statutory target. 93% of householder applications in Harrow are decided within thirteen weeks; extensions of time are common, and the council need not decide on the day. Last seen undecided on 24 Aug 2026.
