What Are You Trying to Do?

Choose one action. Each card jumps to the exact checklist and official link.

Do not mix up the routes: existing application = Cornwall online planning register. New application = national Planning Portal. Site constraints = interactive maps. Unsure if consent is needed = “Do I need planning permission?” guidance.

Map search

Use Map Search for Rural Sites, Farms and Red-Line Areas

Use map when

Address search fails, the site is a field/farm/lane, or you only know the nearby road or village.

How to click

Zoom until property outlines appear. Land with permission may have a red-line area you can click.

Check next

Open the location plan in Documents and confirm the red-line site. Do not rely only on a map pin.

Use layers

Interactive maps help with conservation areas, historic environment, trees, public rights of way and site constraints.

Do not submit map screenshots as plans: use an up-to-date scaled location plan with red line, north point and correct paper size.

Object, Support or Comment Without Wasting Words

1

Read latest plan

Check plan number, revision and upload date first.

2

State position

Object, support or neutral comment. Include PA reference and site address.

3

Use planning headings

Access, parking, design, drainage, privacy, trees, heritage, ecology, PROW or policy.

4

Keep publishable

Use your name/address. Avoid personal data, offensive wording and private disputes.

Useful planning pointsUsually weak points
Highway safety, access, traffic, parkingHouse price impact
Design, scale, layout, materialsLoss of private view alone
Noise, disturbance, smells, flood riskDeveloper identity or motives
Daylight, privacy, trees, protected speciesPrivate neighbour disputes
Planning history, previous decisions, policyCovenants or land ownership rows
If AI helped: add a short disclosure: tool used, what it helped with, and that you checked accuracy and accept responsibility.
After you comment: comments are published, Cornwall does not reply individually, and third parties normally cannot appeal the final decision.
Permission check

Do You Need Planning Permission?

Permitted development

Some minor house works may not need planning permission, but rights can be removed by condition or Article 4 direction.

Building control

Planning permission and building regulations are different. Some projects need both.

Checking service

Cornwall’s informal “Do I need?” service gives advice within 20 working days after all information is provided.

Formal certainty

Use a Lawful Development Certificate if you need a legal determination.

Common triggers

HMO, access/dropped kerb, solar, air-source heat pump, EV charger, demolition, adverts and business use.

Risk

If you build without needed permission or approval, you may have to put things back.

Validation

Validation Checklist: Stop Invalid Status Before It Starts

CheckWhy it mattersBefore upload
National requirementsRequired by legislation.Use correct application checklist.
Local requirementsSet by Cornwall as LPA.Read Cornwall local list items.
Missing informationApplication stays invalid.Respond fully to every validation request.
28-day return riskApplication may be returned if information is not supplied.Watch email after submission.
ConstraintsSome reports depend on site designations.Use interactive maps and specialist guidance early.
Invalid reasons

Common Reasons Applications Are Invalid

Admin

Missing CIL form, wrong/no fee, incomplete ownership certificate, missing agricultural tenant notice.

Plans

Wrong location plan, no north point, wrong scale, wrong red line, “do not scale” wording.

Site context

PROW not shown, constraints not checked, contaminated-land risk not addressed.

Technical evidence

Missing drainage, flood risk, heritage, ecology, bat, barn owl or BNG information.

Money/time risk: returned invalid applications can delay the project and may involve administration deductions depending on the invalid-process stage.

Drawing checklist

  • Use an up-to-date map.
  • Show red-line application site clearly.
  • Show blue-line ownership land where required.
  • Use the right paper size, such as A3 if stated.
  • Upload files upright, readable and logically named.
  • Remove personal phone numbers to reduce redaction delays.
BNG

BNG, Ecology and Exemption Checks

Core rule

Applicable development must deliver 10% Biodiversity Net Gain.

Dates

Mandatory nationally from 12 Feb 2024 for major and 2 Apr 2024 for minor/other applicable applications.

Statement

May need post-development habitat, metric version, off-site gain, credits, hierarchy and draft management plan.

Exemptions

Even if exempt, some information may still be needed. Do not write “de minimis” without justification.

PiP

Permission in Principle does not need BNG at PiP stage; Technical Details Consent deals with it later.

Metric

Use the statutory biodiversity metric and current accepted version.

Enforcement

Report a Breach Only After Checking Permission History

1

Search first

The work may already have permission, PD rights, a lawful certificate, amendment or discharged condition.

2

Use map if needed

Zoom to the site; if land has permission, click inside the red-line area.

3

Check planning harm

Residential work is usually investigated only where a high degree of harm can be shown.

4

Prepare evidence

Name/contact details, site, alleged offender if known, reason, start date, harm, whether ongoing, photos.

Can be planning enforcementUsually not planning enforcement
Unauthorised building/engineering workBoundary, high hedge, party wall or covenant dispute
Breach of planning conditionNoise, smell or light pollution route

Investigation reality: reports are acknowledged, checked, allocated if needed, may require a site visit, and complex enforcement can take a long time.
