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.

Dormers The Green Croxley Green Rickmansworth Hertfordshire WD3 3HX
I wish for work to be done on two trees in my garden: (1) Cut down and remove Tree 1, a large overgrown Leylandii (including the stump). In its place I plan to plant a mulberry tree and other bushes and shrubs that are attractive to birds and pollinators. (2) Reduce the height of Tree 2, a maple tree, by around 3 metres. This tree had its crown reduced by about 1.5-2 metres at the end of 2023 (less than 2 years ago) but it quickly regained the lost height and has now become too tall and thin. Note that when I moved to Dormers cottage around 5 years ago, the garden was very overgrown with very tall connifers. I have applied for several of these to be felled or have their height reduced over the years (several previous appliocations) and I believe this has greatly improved the garden. I think Tree 1 in this application will be the last tree that needs to be removed. Hereafter, it should be routine maintenance only. Please note that as promised in previous applications, I have replaced the trees I removed with a variety of fruit trees and bushes (damsone, crab apple, red currant, blackcurrant, raspberry, gooseberry, cherry) as well as other shrubs (hydrangea, jasmine, blackthorn, philadelphus etc). With better light in the garden, I have also dug a large pond (approx 4 x 2.5 m), intended to encourage wildlife (so, no fish). My intention is to keep adding to the garden shrubs and plants (preferably native UK species) selecting where I can those most attractive to birds and pollinators. I have had a provisional (verbal) quote from a tree surgeon to do this new work
