Use Cornwall’s Planning Register Without Missing a Step
People search for the Cornwall planning portal when they want to find an application, check drawings, submit a comment, track a case, or start a planning permission application.
The key difference is simple: Cornwall Council’s online register is for searching and commenting, while the national Planning Portal is normally used for submitting applications, uploading documents and paying fees.
Quick answer: the “Cornwall planning portal” usually means two official services. Use Cornwall Council’s online planning register to search, view, track and comment on applications. Use the Planning Portal when you need to submit a planning application, upload supporting documents and pay the application fee.
Before submitting, check Cornwall Council’s validation guidance. A planning application can be delayed or marked invalid if the wrong fee is paid, the red-line boundary is wrong, plans cannot be scaled, a Public Right of Way is missing from the block plan, or required reports such as BNG, heritage, drainage, flood risk or ecology are absent.
Cornwall Planning Portal vs Online Planning Register
This is the point most users get wrong. Cornwall Council’s register and the Planning Portal are both useful, but they are not the same service.
| User task | Use this service | What you can do there |
|---|---|---|
| Find a Cornwall planning application | Cornwall Council online planning register | Search by reference, address, parish, postcode area, map or keyword, then open the application record. |
| Read plans, drawings and reports | Cornwall Council online planning register | Use the documents tab to see location plans, elevations, statements, reports, consultee replies and decision notices. |
| Comment, object or support | Cornwall Council online planning register | Create or log into an account, open the application and submit your comment online. |
| Track an application | Cornwall Council online planning register | Track a specific case or set up alerts for applications in an area. |
| Submit a new planning application | Planning Portal | Complete the form, upload plans and supporting documents, and pay fees online. |
| Check whether permission is needed | Cornwall Council and Planning Portal guidance | Check permitted development, use “Do I need” advice, or apply for a lawful development certificate if certainty is needed. |
How to Search Cornwall Planning Applications
A good search saves time. Rural addresses, farm names, cottages, parish names and old district records can be inconsistent, so use more than one search method if the first result looks wrong.
Start with the reference number
If you have a PA reference, use it first. This is the fastest way to find the exact case and avoid nearby applications with similar addresses.
Try address, road, parish or postcode area
If the exact property name does not work, search the road, hamlet, parish or partial postcode. This is useful for farms, named cottages and rural lanes.
Open the full application page
Check the proposal, application type, status, important dates, ward, parish, case officer and whether comments are still open.
Use the documents tab
The summary is not enough. Drawings, reports, consultee replies, officer reports and decisions are normally found in the documents area.
Check for revised plans
Applications often change. Look for uploaded revisions, new plan numbers, amended descriptions or re-consultation before commenting.
What to Read Before You Comment or Apply
The most important information is often hidden inside PDFs. Use this quick guide to understand which file answers which question.
| Document | What it tells you | What to check carefully |
|---|---|---|
| Location plan | Where the application site is. | Red-line boundary, access, parking area, land ownership and whether the right land is included. |
| Block or site plan | How the proposal sits on the plot. | Boundaries, roads, trees, public rights of way, levels, drainage and nearby buildings. |
| Existing and proposed elevations | How the building looks before and after. | Height, roof shape, materials, window position, privacy and visual impact. |
| Design and access statement | The applicant’s design explanation. | Whether the proposal fits local character, site access and Cornwall planning policy. |
| Heritage statement | Impact on listed buildings, conservation areas or historic setting. | Materials, setting, demolition, street scene and harm to significance. |
| Ecology or BNG documents | Habitats, protected species and biodiversity gain. | Survey dates, hedges, trees, bats, birds, irreplaceable habitat and the correct BNG exemption or metric. |
| Officer report | The planning officer’s assessment. | Planning balance, comments, consultee responses, conditions and reasons for approval or refusal. |
| Decision notice | The formal outcome. | Approved plan numbers, conditions, time limits and pre-commencement requirements. |
How to Comment Online Without Weakening Your Point
Cornwall Council says online comments are the quickest route, and email comments are no longer accepted for public planning comments. Comments should focus on material planning considerations.
Useful planning points
- Design, appearance, layout, height, scale or materials.
- Highway safety, traffic, access, turning and parking.
- Privacy, daylight, overlooking or relationship with neighbouring homes.
- Flood risk, drainage, sewerage or critical drainage issues.
- Trees, hedgerows, protected species, open land or countryside impact.
- Listed buildings, conservation areas, archaeology or historic setting.
- Local plan, neighbourhood plan, planning history or previous decisions.
Usually weak or irrelevant points
- Loss of private view.
- Effect on house price.
- Personal criticism of the applicant.
- Private neighbour disputes.
- Developer identity, morals or motives.
- Boundary covenants or private property rights.
- Copy-and-paste objections with no site-specific detail.
Quote the reference and plan revision
State the application reference, address and any plan number or revision date you are commenting on.
Explain your connection to the site
Say whether you are a neighbour, road user, local resident, business owner, community group or landowner.
Use short headings
Separate points into design, access, privacy, drainage, ecology, heritage or policy. This helps the case officer review the comment.
Add evidence where possible
Use plan references, measured distances, photographs, road observations, flood history or local policy references instead of general opinion.
Check if Planning Permission Is Needed First
Do not jump straight into a full application. Some work may be permitted development, some may need a lawful development certificate, and some may need formal permission because of location, designations or use.
Home extensions and outbuildings
Size, height, roof form, location, previous alterations and designations can decide whether permission is needed.
Listed or conservation sites
Windows, doors, roofs, demolition, materials and internal works can need extra consent in protected heritage settings.
Access and dropped kerbs
Creating a new access or parking space can need planning permission depending on the road and site context.
Change of use
HMOs, holiday use, business use, annexes, barns and rural buildings can need permission even with limited building work.
Solar, EV and heat pumps
Many installations can be permitted development, but noise, siting, property designations and building rules still matter.
Lawful Development Certificate
Use this where you need formal certainty that existing or proposed development is lawful.
Apply Through the Planning Portal the Safe Way
Cornwall Council encourages electronic submission and says the Planning Portal lets applicants complete forms, upload supporting documents and pay fees online. The council also notes that the Planning Portal is not run by Cornwall Council.
Before you open the form
- Choose the correct application type.
- Check whether permission is actually required.
- Prepare the ownership certificate and agricultural declaration if needed.
- Confirm the planning fee and any separate service charge.
- Prepare location plan, block plan, existing plans and proposed plans.
- Check whether BNG, heritage, drainage, trees, PROW, flood risk or ecology information is required.
Upload checks
- Use clear PDF names, not “scan final final.pdf”.
- Upload plans in the correct orientation.
- Use one drawing per document where possible.
- Keep scale bars, north points and plan numbers visible.
- Do not use the amend function for a new submission after withdrawal, refusal, approval or returned application.
- Only use file-transfer sites if Cornwall Council has agreed that route.
Validation Check: Stop the Application Becoming Invalid
Validation is the council’s first technical check. If required national or local information is missing, the application can be marked invalid and will not properly move forward until the missing information is supplied.
| Common invalid reason | What it means | How to prevent it |
|---|---|---|
| Missing CIL form | Community Infrastructure Levy information is absent where required. | Check whether a CIL form applies before submission. |
| No fee or incorrect fee | The application cannot be processed correctly. | Use the latest fee guidance and confirm the application type. |
| Incorrect location plan | The site cannot be identified or the boundary is wrong. | Show north, scale, access to highway where relevant, and the correct red line. |
| Public Right of Way missing | A footpath, bridleway or route affected by the proposal is not shown. | Check mapping and show the route on the site or block plan. |
| Plans say “do not scale” | The council cannot scale from the drawing. | Remove that wording and use suitable wording that allows scaling for planning purposes. |
| Missing drainage or flood evidence | Foul drainage, flood risk or critical drainage information is absent. | Prepare the correct drainage form, flood assessment or technical note. |
| Missing heritage or ecology survey | The site may affect listed buildings, conservation areas, bats, barn owls or habitats. | Check constraints early and commission the correct statement or survey before upload. |
Validation Guide PDF: Micro Details Applicants Miss
The official Cornwall Validation Guide is long because it covers different application types. These are the details most likely to help ordinary users before they pay and upload.
Metric scale and scale bar
Plans should be drawn to an identified standard metric scale and include a linear scale bar.
North point and current map
Location and block plans should show north and be based on an up-to-date map.
No watermarked council map
The guide says plans taken from Cornwall Council mapping pages with council watermark or licence details cannot be accepted as planning plans.
Red and blue lines
The red line should show the application site. A blue line may be needed for other nearby land owned by the applicant.
Correct paper size
If the plan says 1:100 at A3, submit it at A3 electronically or in hard copy so it scales correctly.
Missing information timeline
The guide explains that missing information can lead to an invalid letter, a further deadline, closure of the application and a possible administration deduction from refunded money.
BNG, Trees and Heritage Before You Submit
Cornwall sites often need more than a simple form and drawings. Biodiversity, protected trees, conservation areas, listed buildings and historic settings can all affect whether the application is valid and acceptable.
Biodiversity Net Gain
BNG normally requires a 10% measurable biodiversity improvement where it applies. Check whether mandatory BNG applies, whether an exemption is justified, and whether a local BNG statement is needed.
Protected species
Bats, barn owls, nesting birds, hedgerows and habitats can trigger survey needs. Survey timing matters, so do not leave ecology until final upload.
Trees and hedgerows
Tree works, TPOs, conservation-area trees and hedgerow removal can require specific applications, plans, photos or reports.
Listed buildings
Listed building consent may be needed for changes that affect character, including some internal works, windows, roofs and materials.
Conservation areas
Demolition, visible external changes, replacement materials and street-scene impact need extra care in conservation areas.
Interactive mapping
Use Cornwall’s mapping tools before final layout. Check public rights of way, protected areas, flood risk, trees and heritage designations.
Cornwall Local Planning Tips That Save Time
Generic planning guides miss the everyday Cornwall issues: narrow lanes, named cottages, rural access, former mining areas, coast, holiday use and parish-level local knowledge.
Coast and cliffs
For coastal or sloping sites, consider erosion, land stability, drainage, access for construction and visual impact from public viewpoints.
Mining legacy
In former mining areas, ground stability may need early checking before foundations, extensions or new dwellings are designed.
Rural conversions
Barns, Class Q proposals, glamping, farm diversification and holiday use need careful drawings, access details and use-class thinking.
Public paths
If a footpath or bridleway is nearby, show it and think about safety, privacy, temporary construction disruption and long-term access.
Parish and town councils
Check meeting agendas because local councils often discuss applications and submit consultee comments before the final decision.
Neighbourhood plans
A made neighbourhood plan can affect settlement boundaries, design, housing, landscape, parking and local character.
After a Decision: Conditions, Refusals and Changes
A decision notice is not the end. Approved plans, conditions, discharge requirements, commencement deadlines and possible amendments can still decide whether the project is safe to build.
If permission is approved
Read every condition and approved plan number. Some conditions must be discharged before work starts.
If conditions need details
Prepare a discharge of condition submission. Combining conditions carefully may reduce repeat fee events.
If permission is refused
Read the refusal reasons. You may need amended drawings, pre-application advice, a fresh application or an appeal as the applicant.
If plans change later
Check whether a non-material amendment, Section 73 variation, fresh application or other route is needed before building differently.

FAQs About Cornwall Planning Portal
What is the Cornwall planning portal?
Most people use this phrase for Cornwall Council’s online planning register, where you can search, view, track and comment on applications. For submitting a new application, Cornwall Council usually directs applicants to the national Planning Portal.
Where do I search Cornwall planning applications?
Use Cornwall Council’s online planning register. Search by application reference, address, road, parish, postcode area or keyword, then open the documents tab for drawings and reports.
Can I comment on a Cornwall planning application by email?
No. Cornwall Council says public comments by email are no longer accepted. The quickest route is to comment online through the planning register after creating or logging into an account.
What is the difference between Cornwall Council’s register and the Planning Portal?
Cornwall Council’s register is for searching, viewing, tracking and commenting on planning applications. The Planning Portal is used to submit new applications, upload documents and pay fees online.
What should I include in a planning objection?
Include the reference number, site address, your relationship to the site and clear planning reasons such as design, privacy, highway safety, drainage, trees, heritage, ecology or policy conflict.
Can neighbours appeal if Cornwall Council approves an application?
Third parties normally do not have the right to appeal a planning decision. The applicant is the party with the appeal right, so neighbours should submit useful planning comments before decision.
Why is a Cornwall planning application invalid?
Common reasons include missing CIL form, wrong fee, incorrect location plan, missing north point or scale, wrong red-line boundary, “do not scale” wording, missing PROW details, and missing flood, drainage, heritage or ecology reports.
Do I need planning permission for a home extension in Cornwall?
It depends on the size, design, location, previous changes and designations. Listed buildings, conservation areas, Article 4 directions, protected landscapes and site constraints can change the answer.
What is BNG in Cornwall planning applications?
BNG means Biodiversity Net Gain. Where it applies, development must deliver measurable biodiversity improvement. Cornwall Council also has local validation expectations for some BNG information.
What should I check after planning permission is approved?
Read the decision notice, approved plan numbers, commencement deadline and every condition. Some conditions must be discharged before work starts, and building differently from approved plans can create enforcement risk.
