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 householder applications
How this application type works
Householder applications cover work to an existing house and its garden: extensions, loft and garage conversions, porches, outbuildings and similar alterations within the boundary of the home. They cannot be used to create a separate dwelling or change what the building is used for. Councils aim to decide them within eight weeks, and immediate neighbours are usually notified and given a chance to comment.

153 Archway Road, Hornsey, London, N6 5BL
Five Day Notice. T1 Chestnut on the boundary of the gardens on 153 Archway Road and 21 Cromwell Avenue. It stands approximately 60Ft tall of which it goes up 12ft then splits into 6 major limbs (of which 2 have failed). It appears they have failed due full leaf loading on the union and some what looks like white rot. There is a picture of a fruiting body that looks old. The picture with white mark shows where it has failed but also the limb I am most concerned about as this is close to the dysfunction area of the collapsed limbs. If this fails this will go straight through 21 Cromwell Avenue. On the other side of the tree there is an equally large limb which has a potential to fail and this limb would hit 153 Archway Road which is the owner of the trees property. Proposed works: to reduce all major limbs by at least 50% as this will stop the loading from the sail in the wind when it's in full leaf.
