Horsham Council Planning: Applications, Search & Permission
Use this practical guide to search Horsham Council planning applications, use the planning register and map search, comment with planning reasons, check permission, understand fees, follow committee items and avoid invalid application problems.
Find the Right Horsham Planning Route Before You Search or Apply
Horsham planning tasks split into different official routes. Use Public Access for existing applications, documents, comments, weekly lists, property search and map search. Use the Planning Portal when you are submitting a new application online.
This page also explains South Downs National Park cases, comment deadlines, material planning considerations, planning department contacts, Local Plan policy, validation rules, water neutrality updates and post-decision risks.
Quick answer: search existing Horsham planning applications through Horsham District Council Public Access. Use reference, keyword, postcode or one line of address first, then try Advanced Search, Weekly/Monthly Lists, Property Search or Map Search. If the reference starts with SDNP, or the site is inside the South Downs National Park, use the South Downs National Park planning register instead.
For new applications, use the Planning Portal or another accepted submission provider, then follow Horsham’s local and national requirements. If the application is incomplete at validation stage, Horsham will contact the applicant or agent and the application can be returned if missing information is not provided within the council’s stated response period.
Choose the Correct Horsham Council Planning Route
The phrase “Horsham Council planning” can mean search, permission, department contact, committee, policy or a new application. Start with the task, then open the right official page.
| Your task | Correct route | What to do next | Mistake to avoid |
|---|---|---|---|
| Search a planning application | Horsham Public Access | Use simple search, advanced search, property search, map search or weekly/monthly lists. | Opening Planning Portal to search a decided local case. |
| Comment on a live application | Public Access application record | Open the case, read documents, check Important Dates and submit a material planning comment. | Submitting repeated or copied comments; Public Access warns comments can take 5–10 days to appear. |
| Search only documents by reference | Horsham document-only search | Enter the planning reference code if you only need documents. | Using document-only search when you want to comment; Horsham says you cannot comment through that route. |
| Apply for permission | Planning Portal or accepted submission provider | Check local/national requirements, CIL, validation and Building Regulations first. | Uploading drawings without the local validation documents. |
| Check if permission is needed | Horsham free online guide, LDC or pre-application advice | Use the guide as guidance only; check planning history and conditions separately. | Treating the free guide as a formal planning decision. |
| Policy or Local Plan question | Planning Policy / Strategic Planning | Check HDPF, emerging Local Plan, Horsham District 2045, neighbourhood plans and evidence base. | Contacting the application case officer for strategic policy questions. |
Horsham Council Planning Search: Best Order
Public Access lets users search planning applications and enforcements by keyword, application reference, postcode or a single line of an address. Use the cleanest identifier first.
Use the reference number first
Horsham shows reference examples such as DC/26/1234. If you have a site notice, neighbour letter, agent email or decision notice, copy the reference exactly.
Try postcode or one address line
If you do not have a reference, search the postcode, road name, building name, single address line, parish, applicant keyword or proposal term such as “extension”, “barn”, “change of use” or “solar”.
Use Advanced Search when results are crowded
Advanced Search is better when you need date ranges, application status, proposal keywords or a narrower filter for a busy street or development site.
Check record type
Public Access can show planning applications and enforcement records. Confirm you are reading the correct case type before quoting a reference or submitting a comment.
Copy the key details before closing
Record the reference, site address, status, important dates, latest document date, decision notice, appeal status and any condition numbers.
Planning Register, Map Search, Property Search and Weekly Lists
Use different Public Access tabs for different jobs. A map search helps with land, farms, sites without a normal address, boundary questions and nearby applications.
Map Search
Use map search for fields, estates, commercial land, barns, edge-of-village sites, farm buildings, highways, greenfield locations and applications near a boundary.
Property Search
Use property search when you want planning history for a specific address before buying, objecting, applying or checking previous conditions.
Weekly / Monthly Lists
Use lists to find recently received, validated or decided applications without knowing a reference number. They are helpful for local monitoring.
Applications in the South Downs National Park Area
Some land in or near Horsham District falls under the South Downs National Park planning route. Horsham tells users to use the South Downs National Park planning website if the application number starts with SDNP or the site is located within the National Park.
When to use SDNPA
- The reference begins with SDNP.
- The proposal site is inside the South Downs National Park.
- You are checking a planning application, appeal or treeworks application controlled by SDNPA.
- You need SDNPA weekly lists, map search or comment guidance.
When to return to Horsham
- The reference is an ordinary Horsham District application reference.
- The case is outside the National Park.
- You need Horsham District Council policy, CIL, local validation or planning department contacts.
- You need Horsham Planning Committee information for a Horsham case.
Documents to Read Before You Comment, Buy or Build
Never rely only on the summary line. Open the latest documents, because revised drawings, conditions, objections, officer reports and committee reports can change the practical position.
| Document | What it tells you | Micro-check before acting |
|---|---|---|
| Location plan | Shows the application site and land needed for the development. | Check red-line site area, roads, access, boundary, blue ownership land and nearby buildings. |
| Block or site plan | Shows the proposal in relation to boundaries and surroundings. | Check scale, north, parking, trees, public rights of way, adjoining properties, gardens and levels. |
| Elevations and floor plans | Show how the building changes. | Check windows, height, roof form, materials, overlooking and whether the plan is the latest revision. |
| Planning statement | Explains the proposal against local and national policy. | Compare the statement with Horsham District Planning Framework, neighbourhood plan and site constraints. |
| BNG / ecology report | Explains habitats, biodiversity metric, mitigation and net gain approach. | Check whether the baseline habitat map, metric and post-development plan match the red-line site. |
| Water, drainage or flood evidence | Explains water, surface water and flood-risk issues. | Check if the current water neutrality update changes the documents needed for the case. |
| Officer or committee report | Shows assessment, recommendation and decision reasoning. | Read material considerations, conditions, reasons for refusal and committee speaker deadlines. |
| Decision notice | Confirms approval, refusal and conditions. | Check approved plan numbers, pre-commencement conditions, time limit, appeals and CIL notes. |
How to Comment, Object or Support a Horsham Planning Application
Horsham welcomes comments in support or objection, but the decision can only take account of planning considerations. Comments that are offensive, discriminatory or irrelevant can be rejected or carry little weight.
Relevant material considerations
- Planning policy, government guidance, case law and previous decisions.
- Highway safety, traffic, access and parking.
- Noise, disturbance and smells.
- Overshadowing, overlooking and loss of privacy.
- Effects on listed buildings and conservation areas.
- Loss of trees, design, appearance, materials and character.
- Drainage, BNG, air quality, flood risk and local constraints where relevant.
Issues that usually do not help
- Effect on property value.
- Private property rights.
- Personal or financial circumstances.
- Loss of private views.
- Moral or religious issues.
- Restrictive covenants.
- Private disputes between neighbours.
Open the Important Dates tab
Most comments should be submitted within 21 days from the relevant notification, site notice or Sussex Times advertisement date. EIA development has a 30-day publicity period.
Write under planning headings
Use headings such as design, access, privacy, trees, conservation, parking, policy, BNG or drainage. This makes your comment easier to assess.
Use evidence, not repetition
Public Access warns large comment volumes can delay publication and asks users not to duplicate another contributor’s comment. Write your own site-specific reasons.
Know the committee cut-off
If the application is going to Planning Committee, Horsham says comments are considered until midday on the Friday before the scheduled committee meeting. Late representations after the deadline are not taken into consideration.
Track Applications, Save Searches and Get Email Alerts
Public Access registration gives extra tools. Once registered, you can track applications, save searches and receive email notifications about tracked applications and new search results.
Track one case
Use this for an application you already know. Tracking keeps the case in your profile and helps you see updates.
Save an area search
Use this for a street, village, postcode, ward or rural area so you can catch new applications, not just one existing reference.
Use email notifications
Notifications are helpful, but still check the live application when deadlines, amended plans or committee dates matter.
Horsham Council Planning Permission: Check Before You Apply
Horsham says it is important to find out if planning permission is needed before changing a property. Doing work without permission can lead to retrospective applications, reversal of works or enforcement action if the development is harmful.
Use the free online guide
The free guide asks for location, postcode and details of the proposed works, then gives guidance. It is not a formal planning decision and does not include planning history or conditions.
Use an LDC for formal proof
A Lawful Development Certificate can confirm whether proposed or existing works do not require planning permission.
Check Building Regulations too
Planning and Building Regulations are separate. Extensions, loft conversions, structural alterations and new homes can need Building Control even after planning permission.
Apply for Horsham Planning Permission Without Avoidable Delay
Horsham says one way to apply online is through the Planning Portal, which lets users complete the form, attach documents and submit payment. The Council also notes alternative online providers are available.
Before you start the form
- Confirm the correct application type.
- Check if the site is inside the South Downs National Park.
- Check if Building Regulations approval will also be needed.
- Check if the proposal is CIL liable.
- Read local and national requirements.
- Check whether pre-application advice would reduce risk.
Before upload
- Prepare the correct form and fee.
- Prepare ownership certificate and notices.
- Use the right location plan, block plan and drawings.
- Include water neutrality or updated water information only where current guidance requires it.
- Include BNG, drainage, heritage, tree, air quality or planning statement information where triggered.
- Make every PDF legible, correctly scaled and correctly named.
Planning Application Fees, Planning Portal Payments and CIL
The planning fee depends on the type and scale of development. Horsham says if you submit through the Planning Portal, payment is taken through the Planning Portal and you do not need to use the Council’s payment form.
| Fee / payment issue | What it means | Best action |
|---|---|---|
| Planning Portal application | Payment is taken through the Planning Portal. | Do not use Horsham’s direct payment form for a Planning Portal application. |
| Email or post application | Direct Council payment may apply if the application was submitted directly. | Use the Council’s payment route only when the live page says it is available and applicable. |
| Fee calculation | Fees are linked to national fee regulations and can change. | Use the official Planning Portal fee calculator or Horsham fee list before payment. |
| CIL | Horsham has a CIL Charging Schedule; new dwellings or 100sqm+ net additional floorspace can be potentially liable. | Check CIL before submitting and before starting work, including relief or exemption rules. |
Horsham Local and National Validation Requirements
Horsham’s Local Information Requirements explain what information is normally required so the decision maker and third parties understand the proposal. The exact list depends on development type, site constraints and scale.
| Validation item | Why it matters | Micro-check |
|---|---|---|
| Application form and correct fee | Required as a national validation item. | Use the correct application type and fee route before submission. |
| Location and site plan | Shows the site, land required and relationship to surroundings. | Use correct red line, metric scale, north and scale bar. |
| Ownership certificate and notices | Required where land ownership or notices apply. | Use certificate A, B, C or D correctly and serve notices where required. |
| Water neutrality / water information | Horsham has had site-specific water neutrality rules and updates. | Check the current water neutrality page before submission. |
| BNG assessment | Horsham’s validation list reflects mandatory BNG for relevant development and local BNG information. | Prepare BNG statement, habitat survey map/photos and biodiversity metric where required. |
| Air quality assessment | Triggered for major development, AQMA proximity and certain B8 storage/distribution uses. | Check Cowfold and Storrington AQMA relevance and Sussex air quality guidance. |
| Surface water drainage statement | Required for development proposals for buildings, hard surfacing and extensions. | Explain how surface water will be managed in proportion to the proposal. |
| Planning statement | Required for major development and minor development except householder applications. | Explain how the proposal fits national, regional and local policies. |
Plans, Scale Bars and Measuring Horsham Planning Drawings
Plans submitted with Horsham applications must be to scale and include a scale bar. Horsham’s validation guidance says drawings must use a recognised metric scale, include north and scale bar, and must not use “do not scale”.
Scale examples from Horsham guidance
- Elevation or floor plans: usually 1:50 or 1:100.
- Block plans: usually 1:500.
- Location plans: usually 1:1250 or 1:2500.
- Block plans may be 1:200 or 1:500 depending on proposal.
- Tree-impact plans may need closer scale such as 1:200.
Digital PDF checks
- The electronic page size must match the stated drawing size.
- All documents must be legible in all material respects.
- Only one copy of each document or plan is needed electronically.
- Hard-copy submissions normally need more copies.
- Use clear file names and drawing references.
Water Neutrality in Horsham: Current Applicant Warning
Water neutrality has been a major Horsham planning issue because of the Sussex North Water Supply Zone and Arun Valley habitats. The current council page says Natural England withdrew its September 2021 Water Neutrality Position Statement on 31 October 2025, but applicants should still check the live page because the Council remains the competent authority under the Habitats Regulations.
What the current page says for applicants
- No water neutrality statement is now required.
- No payment into SNWCS is needed to use the Southern Water capacity referred to by the Council.
- No bespoke conditions or S106 obligations are required to demonstrate water neutrality.
- New housing will still be conditioned to meet the Building Regulations Part G Optional Technical Standard where applicable.
Why you still need to check
Because water neutrality rules have changed recently and development remains within a water-stressed area, applicants should read the current Horsham water neutrality page before submitting, amending, varying conditions or relying on old agent advice.
Planning Committee, Speaking at Committee and Planning Policy
Most applications are decided under delegated powers, but some go to Planning Committee. Policy also matters because the decision is tested against the development plan, national policy and material considerations.
Planning Committee
Horsham’s ModernGov page lists Planning Committee meetings, agendas and minutes. Public planning committee meetings are also livestreamed wherever possible. If your case is going to committee, check the agenda, report, speaker rules and comment deadline early.
- Check whether the application is on an agenda.
- Read the officer report and recommendation.
- Check the midday Friday comment cut-off before the scheduled committee meeting.
- Use the speaking-at-committee guidance if you want to speak.
Planning Policy and Local Plan
Horsham says planning policies guide how, where and when development takes place. The current adopted Local Plan is the Horsham District Planning Framework, and the Council has also worked on the Horsham District Local Plan 2023–2040 and Horsham District 2045.
- Check the HDPF for current adopted policies.
- Check neighbourhood plans by parish where relevant.
- Check planning obligations, affordable housing, CIL and biodiversity guidance.
- For policy queries, contact Strategic Planning rather than the application search portal.
Horsham Planning Department: Who to Contact

Horsham Planning Search and Comment Troubleshooting
If the portal does not behave as expected, the issue is often the search tab, reference type, login state, SDNP boundary or comment timing.
| Problem | Likely cause | Useful fix |
|---|---|---|
| No result in simple search | Reference typo, postcode too narrow, address wording different, SDNP case or wrong record type. | Try reference only, postcode only, one address line, advanced search, property search, map search or SDNP search. |
| Cannot comment | You may be using document-only search, the case may be decided, or the comment route may require profile/login steps. | Open the full Public Access case from the main planning system and check Important Dates. |
| Comment not visible yet | Public Access notes high comment volumes and says comments may take 5–10 days to appear. | Do not submit duplicates if you have a confirmation email. |
| Planning Portal payment confusion | Planning Portal applications are paid through the Planning Portal. | Use Horsham payment route only for direct post/email submissions where the live page says it applies. |
| Planning permission checker says likely no permission | The free guide is not formal and does not check planning history or conditions. | Check planning history and consider a Lawful Development Certificate for formal certainty. |
