What happens while it is decided
The process from here
This application is with Three Rivers for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.
The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.
About lawful development applications
How this application type works
A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.

25/1297/TPO Refused
9 The Roughs Northwood HA6 3DE
T1 - Oak x 1 - reduce by 2m on height and 3m on overall spread, this will leave the tree at around 21 m in height with an approximate crown spread of 5-6 m. T2 - Oak x 1 - reduce by 2m on height and 2m on overall spread (as T1 above) T3 - Oak x 1 - reduce by 1-1.5m on height to clear dieback, prune back the south and east sides by around 1.5 m to leave these sections at about 2.5 m in length and so create a reasonably symmetrical crown. Reasons: trees 1 & 2 are woodland/field species rather than garden trees and these are now becoming somewhat large for this suburban location, Mr Ellis also has some concerns because the property is located within an area that has a shrinkable superficial site geology. Tree 3 is suppressed by the former two trees and as a result has developed a very asymmetrical crown with appreciable deadwood at the higher levels.
