Planning designations

National planning layers that control what you can change — a Conservation Area, Green Belt, protected landscape or Tree Preservation Order can all restrict alterations and works.

Typical result: Not designated

Whether or not a property sits inside a planning designation directly affects what you can do to it. A Conservation Area or a Tree Preservation Order can restrict alterations, extensions, cladding, windows and work to trees. Green Belt and protected landscapes constrain new development. Confirming the absence of these designations is just as useful as flagging their presence.

About this data

These are national planning-data layers published by MHCLG through planning.data.gov.uk, recording whether a property falls inside a Conservation Area, Green Belt, protected landscape or similar. They are published under the Open Government Licence.

What we check

Conservation Area
Restricts demolition and many external alterations; extra controls on windows, cladding and trees.
Green Belt
Strong presumption against inappropriate new development in the countryside around towns.
National Landscape (AONB)
Protected landscape where development and its design are more tightly controlled.
Tree Preservation Order
Makes it an offence to fell, lop or damage protected trees without consent.
Others
Ancient Woodland, Registered Park & Garden, Scheduled Monument, and SAC/SPA/Ramsar nature sites.

How we report it

We report each designation as present or absent at the property point, in a clear table. Where a designation is present — a Conservation Area or TPO in particular — we flag it prominently, because it changes what you can alter without permission.

Designations are screened at the property point from national data. Always verify precise boundaries with the local planning authority before carrying out works — a Conservation Area boundary can run down the middle of a street.

What it means for you

If you simply want to live in the home, most designations have little day-to-day effect. If you intend to extend, re-clad, replace windows, or work on trees, a Conservation Area or TPO means you should check with the planning authority first — unauthorised work can be an offence and expensive to put right. Buyers who value the character these designations protect often see them as a positive; either way, it is better to know before you exchange.
