Conservation areas, and why the usual rules stop applying
Inside a conservation area the permitted development a trade relies on shrinks, and an Article 4 direction can remove it altogether. Both are invisible unless you look.

The same job, a different answer
Permitted development rights are tighter inside a conservation area. Work that needs no application on an ordinary street — cladding, some roof alterations, a satellite dish on the front — can need full permission a hundred metres away, and the boundary is not marked on the ground.
The practical risk for a trade is quoting the job before checking. The homeowner does not know, the estate agent did not mention it, and the first anyone hears is an enforcement officer.
Article 4 directions remove what is left
A council can make an Article 4 direction withdrawing permitted development rights in a defined area. Where one is in force, work that would ordinarily need nothing — replacing windows and doors, changing a roof covering, altering a chimney, rebuilding a boundary wall — needs planning permission.
Some conservation areas carry one and some do not, and the scope varies between them. It is a local decision, published locally, which is precisely why it catches people out.
Trees have their own rule, and it is six weeks
Trees in a conservation area that are not already protected by a Tree Preservation Order are covered by section 211 of the Town and Country Planning Act 1990. You must give the council six weeks’ notice — a section 211 notice — before doing the work, unless an exception applies.
Six weeks is longer than most jobs are scheduled. If scaffolding needs a branch out of the way, that notice wants serving when the job is quoted, not the week before. Work may start earlier if the council consents in the meantime.
How to check before you quote
Tradecue shows the planning constraints recorded against an application, including conservation areas, so a lead in one is visible before you ring. The council’s own mapping is the authoritative version, and for a listed building — a separate and stricter regime — listed building consent is required for anything affecting its character, inside or out.
