How to check a property's conservation area status

1. Start with the free postcode check

Enter the full postcode in the free checker. Note the conservation area name, the source shown and the nearby listed-building records. Open the map and identify the street and property you are interested in. The checker brings these records together so you have a starting point for further research.

The location used for a postcode is a representative point, rather than the footprint of every home using it. A postcode can cover several addresses. If the point is near a boundary, homes sharing that postcode may be on different sides. Treat the inside-or-outside answer as a screening result, then check the exact building.

2. Follow the boundary to the council's records

Find the local planning authority for the address and open its conservation area map or planning constraints map. Search for the exact address and zoom in far enough to distinguish the building from adjoining properties. Compare the position with the map in HeritageCheck.

Look for a conservation area appraisal or management plan as well as the boundary. These explain the area's character and the features the council is trying to preserve. Keep the document title and date with your notes. If the maps disagree, the boundary is hard to read or your building sits on its edge, ask the council to confirm the position before relying on the result.

• Give the full postal address, including a flat number where relevant.
• Include the conservation area name and a link to the map you checked.
• Ask whether the whole property, or only part of its site, is within the boundary.
• Ask which current appraisal, direction or other document applies.

3. Check listing and Article 4 directions separately

A conservation area protects the character of a place; listing relates to particular buildings or structures. A listed building nearby does not establish that your home is listed. Follow the official record, check the address and description, and ask the council if the extent of protection is unclear.

An Article 4 direction can remove specified permitted development rights. Its map and wording matter: a direction covering a nearby street or a different type of work may not apply to your proposal. Ask the council which directions and planning conditions affect the exact property. Permission requirements depend on the work and location, and rules differ across England, Wales and Scotland.

4. Turn the findings into questions about your plans

Write down what you want to change, where it is on the building and the materials you intend to use. A clear question about replacing street-facing windows is more useful than asking whether renovations are allowed. For a purchase, share the address, map and documents with your conveyancer so they can carry out the appropriate official searches.

If you are considering an extension, alterations to a listed building or work to a tree, check the relevant consent or notice requirements before arranging the work. A positive checker result does not say that work is prohibited, and a negative result does not establish that permission is unnecessary.

Three situations that need a closer look

A home at the end of a street: the postcode point lies inside a conservation area, but the boundary may end before the last house. Confirm the house on the council's map rather than applying the result to every address.

A flat close to a listed terrace: the nearby listing is useful context, but it may describe another building. Match the list entry to the flat's building and confirm any uncertainty about what is protected.

A home outside a conservation area: other constraints can still apply. Check listing, Article 4 directions and the council's planning records rather than treating the result as a general permission to build.

When a Heritage Planning Report helps

The free checker answers a postcode-level question. For a selected property in Greater London, a paid Heritage Planning Report brings together available heritage designations, planning applications, Article 4 information and EPC history, with source links and explanations of gaps, in a PDF you can keep or share.

The report saves you bringing those records together yourself. It is a starting point for buying or planning changes; council decisions, official searches and professional advice remain separate. See the finished public samples before deciding whether this is useful for your property. The report page shows the current price, availability and delivery information before payment.
