What a grant of permission means
The process from here
Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.
Work must normally begin within three years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.
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.

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.
