Hillingdon Council can only weigh objections that raise a material planning consideration. Personal disputes, loss of a view and property value are not material and are set aside. These are the grounds that do count, with what Hillingdon's planning officers will expect you to evidence for each.
Then write the objection letter, or check what counts as a material consideration before you start. Objections normally have to reach Hillingdon Council inside the 21-day consultation window.
