Harrow Planning Portal: Search, Applications & Permission
A practical Harrow-specific guide for searching planning applications, commenting online, checking permission, applying safely and avoiding validation delays.
Find Harrow Planning Records, Comment Correctly and Apply Without Delays
Use this page when you need the Harrow planning portal search, a free online planning application search by address, a planning permission route, or a simple way to understand documents before commenting.
It separates Harrow’s planning search, MyHarrow comment login, Planning Portal application route, validation checklist, CIL, trees, conservation areas, Article 4, appeals and enforcement so you can act on the right official page.
Quick answer: use Harrow’s planning search website to find planning applications submitted in Harrow. You can search without an account. To submit comments, you need to sign in or register for a MyHarrow account, enter the planning reference, and use the “Make a representation” section below the map.
For new planning permission applications, Harrow points applicants to the national Planning Portal. Before uploading, check the Harrow validation requirements, avoid incorrect file names, prepare proper plans and confirm whether CIL, BNG, flood risk, conservation, Article 4, protected trees or a lawful development certificate route applies.
Start With the Right Harrow Planning Route
Most users search “Harrow planning portal” for one of six different jobs. Pick the right one before opening official links.
Search a planning application
Use Harrow’s planning search website for applications, documents, status, decisions, appeals and enforcement-related records where available.
Comment on a live application
Use a MyHarrow account, search under the planning option, enter the reference number and make a planning-focused representation.
Check planning permission
Use Planning Portal permitted development guidance, Harrow constraints, and consider a Certificate of Lawful Proposed Development if you need formal proof.
Submit a new application
Apply through the Planning Portal, calculate the fee, upload the right documents and avoid Harrow’s file naming and validation problems.
Protected tree or conservation issue
Check TPOs, conservation areas and Article 4 directions before pruning trees, changing roof tiles, demolishing buildings or altering frontages.
Possible planning breach
Search planning history first, then use Harrow’s enforcement route with address, dates, description, owner details and PDF evidence.
Harrow Planning Search, MyHarrow and Planning Portal: What Each One Does
These systems are connected in the user journey, but they are not the same tool.
| Your task | Correct route | Micro-step before you click |
|---|---|---|
| Search Harrow planning applications free online | Harrow planning search website | Start with reference number, then postcode, address, map or keyword. |
| Search by address | Harrow planning search | Use one line of the address first; if no result, try road name, postcode, property name or map search. |
| Submit an objection or support comment | MyHarrow account + planning option | Use planning reasons only and upload attachments as PDF files. |
| Apply for planning permission | Planning Portal | Check Harrow validation requirements, fees, file names, location plan and supporting documents first. |
| Ask informal planning advice | Duty planner or pre-application advice service | Use duty planning for informal phone queries; use pre-app for project-specific written advice. |
| Check if work is lawful | Certificate of Lawful Proposed Development | Use CLPD if you need formal proof that proposed works do not need planning permission. |
Harrow Planning Applications Search: Best Order
Use this order to avoid false “no results” searches, especially for flats, estates, corner plots, older references and sites with revised applications.
Search the exact reference first
Use the reference from a neighbour letter, site notice, agent email, committee agenda, decision notice or appeal record. Remove spaces copied from PDFs.
Try postcode and one address line
Do not paste the full Royal Mail address if it fails. Try house number plus road, postcode only, road only, building name, estate name or local landmark.
Use map search for land, estates and unclear addresses
Map search helps with open land, garages, rear gardens, school sites, corner plots, commercial estates and properties without a simple house number.
Open related cases before acting
One site may have prior approvals, lawful development certificates, variations of condition, non-material amendments, appeals or enforcement records.
Copy the key record details
Save reference, address, status, decision date, latest drawing revision, case officer, consultation period, condition numbers and appeal status.
Harrow Planning Applications Search by Address Free Online
Address search is useful, but it can fail when a record uses a site description rather than the postal address. Use this small troubleshooting table.
| Search problem | Try this | Why it helps |
|---|---|---|
| Full address gives no result | Use only the postcode or only the road name. | Planning systems may store addresses differently from Royal Mail. |
| Flat or maisonette not found | Search the building name, parent number or postcode area. | The record may sit under the block or freehold property. |
| Land behind a property | Use map search and nearby road names. | Rear land may be described by location rather than a numbered address. |
| Old application not obvious | Search property history and related cases. | Older records, appeals or amendments may not appear under the newest search phrase. |
| Too many results | Add date range, application type, status or proposal keyword. | Filters reduce noise where a road has many extensions or tree applications. |
Documents to Open Before You Comment, Buy or Build
The application summary is not enough. Use this order to read the Harrow planning file like a practical checklist.
Location plan
Check red-line boundary, blue land, highway access, adjoining buildings and whether the application site matches the proposal.
Block plan and site plan
Check boundaries, dimensions, access points, roads, footpaths, trees, hedgerows, hard surfacing and boundary treatment.
Elevations and floor plans
Check height, windows, roof shape, materials, demolition, proposed walls, neighbouring relationship and latest revision number.
Technical reports
Look for BNG, ecology, flood, drainage, trees, heritage, daylight, transport, noise, contamination and planning statements.
Comments and consultees
Read neighbour comments, transport, tree, conservation, drainage, environmental health and officer responses before writing your own view.
Decision notice
Read approved plan numbers, refusal reasons, conditions, time limits, appeal notes and whether condition discharge is needed before work starts.
How to Comment, Object or Support on a Harrow Planning Application
Harrow says only comments on planning issues will be considered. The best comments are short, specific and linked to the submitted drawings.
Create or sign in to MyHarrow
You need an account to comment. After signing in, choose Planning, then Search, and enter the planning reference number.
Use “Make a representation”
Enter your comment in the representation section below the map. If uploading an attachment, use PDF format.
Use planning reasons only
Useful topics include design, scale, overlooking, daylight, parking, access, highway safety, trees, heritage, drainage, noise, policy and amenity.
Avoid private or weak points
House price, private disputes, anonymous allegations, party wall issues and personal criticism are usually weak or non-planning matters.
Check Harrow Planning Permission Before You Apply
Planning permission is commonly needed for building something new, making a major change such as an extension, or changing the use of a building. Some development may be permitted development, but Harrow constraints can change the answer.
Householder projects
Check extensions, lofts, outbuildings, garages, dropped kerbs, fences, walls, roof changes and annexe proposals before starting.
Lawful development certificate
A CLPD gives formal confirmation that a proposed development is lawful for planning purposes. Harrow recommends getting one before starting works where certainty matters.
Conservation and Article 4
Conservation areas and Article 4 directions can remove normal permitted development rights, so extra planning permission may be needed.
Apply for Harrow Planning Permission Without File or Description Errors
Harrow directs applicants to the Planning Portal. A smoother application starts before the upload screen.
Before you apply
- Confirm whether planning permission is needed.
- Check whether pre-application advice is worth paying for.
- Choose the correct application type.
- Prepare ownership certificates and notices where needed.
- Use the Planning Portal fee calculator.
- Check Harrow’s local validation requirements and national validation requirements.
Proposal description tips
- Keep the description clear and precise.
- State key parts: type, scale and location.
- Do not use the description as a justification statement.
- Say if any part of the proposal is retrospective.
- For changes of use, state existing and proposed use and use class where relevant.
- For condition changes, quote the original reference and condition number.
file_name.pdf or file.name.pdf., because the application may not be submitted.
Harrow Validation Checklist PDF Converted Into User Steps
Harrow’s validation PDF is not just a formal document. It decides whether the application has enough information to be processed correctly and avoid invalid status.
| Validation issue | What Harrow expects | Applicant action |
|---|---|---|
| Correct form and fee | Appropriate 1APP form, relevant certificates, correct fee and required national/local information. | Check application type and fee before uploading. Do not submit a nearly-complete application just to get a reference. |
| Invalid application response | If an application is invalid, Harrow may ask for missing information and give 21 days to provide it or challenge the request. | Respond quickly and completely. Keep one clear document schedule and label revised documents. |
| Planning Portal upload | Documents should be PDF, correctly orientated, with no zip/exe files, scale bars and key dimensions on plans. | Compress large PDFs, check orientation and avoid unsupported file types before submission. |
| Email submission | The validation PDF lists separate email file limits and PDF expectations. | Use the official route indicated for your application and keep files clearly named and separated. |
| GDPR on plans | The PDF tells applicants not to put their or their client’s name on plans. | Remove names, signatures, personal emails and private phone numbers from public planning files. |
Plan and Drawing Rules Harrow Applicants Should Check
Poor drawings cause avoidable delays. Use this checklist before you pay the fee.
Site location plan
- Use 1:1250 or 1:2500 scale.
- Use an up-to-date plan.
- Include direction of north and a scale bar.
- Show at least one named road and enough context to identify the site.
- Use a red line around the application site and extend it to the highway.
- Show other nearby applicant-owned land in blue.
Block, elevation and floor plans
- Use 1:200 or 1:500 for block plans where required.
- Show existing and proposed versions where relevant.
- Include written dimensions to boundaries.
- Show roads, footpaths, access points, public rights of way, trees, hedgerows and boundary treatments.
- Use 1:50 or 1:100 for elevations and floor plans where required.
- Include scale bars and clear drawing numbers.
Harrow Local Checks: Conservation, Trees, HMOs, Local Plan and Design
A Harrow application is stronger when it addresses local constraints early, not after validation or neighbour objections.
Conservation areas
Harrow conservation areas include Harrow on-the-Hill, Pinner, Stanmore and Edgware, and Harrow Weald. SPDs explain character and expected design responses.
Article 4 directions
Article 4 can remove permitted development rights. In affected areas, normal small changes may need planning permission.
Protected trees
TPO trees and trees in conservation areas need consent or notice before most works. Harrow responds to TPO works within six weeks and conservation-area tree works within eight weeks.
HMOs and use changes
Check use class, HMO controls, Article 4 updates and planning history before converting a family house, shop, office or other building.
Harrow Local Plan 2021–2041
The adopted Local Plan is key context for growth, housing, town centres, design, environment and local planning decisions.
Building control is separate
Most extensions and alterations also need building regulations approval, even where planning permission is not required.
CIL, BNG, Flood Risk and Drainage Before Upload
Technical forms and assessments often decide whether an application is complete. Check these early, especially for new dwellings, larger floorspace, critical drainage areas and biodiversity-sensitive sites.
| Topic | Harrow-specific detail | What to do |
|---|---|---|
| Community Infrastructure Levy | Harrow CIL and Mayoral CIL can apply where over 100 sq m gross internal floorspace is created or one or more dwellings are created. | Submit Form 1: CIL Additional Information with the planning application and check live indexation rates. |
| BNG assessment | The validation PDF includes Biodiversity Net Gain Assessment as a national requirement under Schedule 7A where applicable. | Prepare the biodiversity metric, habitat information and ecological evidence before finalising layout. |
| Flood risk | Harrow uses mapped flood zones, surface water risk and critical drainage areas to decide when a site-specific FRA is needed. | Check flood mapping, especially for extensions, hard surfacing, one-hectare-plus sites and critical drainage areas. |
| Sustainable drainage | Major and minor developments and any development in a Critical Drainage Area may need a Surface Water Drainage Strategy. | Plan SuDS, runoff control and greenfield rate issues early, not after the design is complete. |
After You Submit: Validation, Site Visit, Decision and Committee
After submission, Harrow updates applicants in writing at key moments and says progress can also be tracked on the planning search website.
Decision timescales
Harrow says it has eight weeks to decide if an application is valid, 13 weeks for large or complex applications, and 28 days for non-material amendments. The time starts once the application is registered.
Site visit and assessment
A case officer may visit the site, assess policy, consider consultation feedback and then recommend approval or refusal in a report.
Delegated or committee decision
Harrow says applications are determined either by delegated powers or planning committee, and delegated powers decide about 99% of applications.
Approval conditions
Read every condition. Materials, landscaping, drainage, tree protection, hours, access or use restrictions can require further approval before work starts.
Appeals and Enforcement: Use the Right Route
Appeals and enforcement are not general complaint routes. They have specific rules, deadlines and evidence requirements.
Appeal a planning decision
Harrow says applicants can appeal refusals, conditions, non-determination or enforcement notices through the Planning Inspectorate. Most appeals must be made within six months, with shorter periods for householder, minor commercial and advertisement appeals.
Report a suspected breach
Before reporting, search planning history and the Enforcement Notice Register. Harrow investigates issues such as building works without permission, breach of conditions, unauthorised use, illegal outbuildings, TPO breaches, HMOs and untidy land.
