Planning Rejection Risk Analyzer
Use this tool once the project route is starting to look real and you want to understand the objections most likely to derail a planning application. It uses the same structured project model as the Planning Decision Engine, but focuses on refusal risks, not permission route.
Run The Rejection Risk Analysis
Work through the same style of project questions, then let the tool surface the refusal risks that are most likely to matter.
What This Tool Is Good For
What it answers well
It helps you spot the planning objections a council is most likely to raise, such as bulk, privacy, design character, parking or heritage impact.
Why it is useful early
You can use it before drawings are final to see which design choices are most likely to need rethinking before an application goes in.
Best next move
Use the output to reduce the weak points in the proposal, then open the matching project guide, local authority layer or decision tool if the route still needs checking.
Questions People Usually Ask After The Result
Keep this block for the interpretation and trust questions that usually appear once the tool has narrowed the answer.
Is planning rejection risk analyzer a final answer?
No. Planning Rejection Risk Analyzer is built to narrow the planning question quickly, not to replace the project guide, local authority layer or formal verification where certainty matters.
What details most often change the result?
Design quality, neighbour impact, heritage sensitivity, parking and local policy context are the details most likely to make the risk profile worse or better.
When should I verify formally?
Verify the next move formally once the scheme is still worth pursuing but the risks are high enough that redesign or pre-app advice could save time.
What page should I open next?
Open the matching project guide next, then use the local authority layer if policy or site context is driving the risk.
Why does local context still matter after the tool?
Because conservation areas, listed buildings, Article 4, planning history and council-specific judgement can still make a familiar-looking result less reliable on a real site.
Questions This Tool Is Best At Narrowing
- Could this application be refused?
- What are the main planning objections here?
- Will neighbour impact or design character be a problem?
- Which part of the proposal is most likely to trigger resistance?
How This Tool Fits Into The Wider Planning Process
Planning Rejection Risk Analyzer is intended as a fast planning triage step based on common UK planning considerations and permitted development limits.
Use it to narrow the question, then move into project guides, local authority pages or formal confirmation if the scheme is close to a limit. The tool should help you spend money in the right order, not tempt you to stop checking too early.
Need A More Tailored Steer Than The Tool Result?
If planning rejection risk analyzer has narrowed the question but the answer still depends on your exact site, local authority area or project details, use the structured guidance form instead of relying on another broad rule of thumb.
Best for
Borderline, awkward or site-specific cases where broad guidance has helped, but the answer still turns on facts that are unique to your property or proposal.
What the reply aims to do
The reply aims to narrow the likely route, flag the tripwires that matter most, and tell you which verification step is safest before more money is spent.
What to include
Property type, council area, location, the change you want to make, approximate dimensions, relevant heritage or flat-related details, previous additions and the main concern.
Important: Replies are informational personalised guidance based on the details you provide and publicly available information. They are not formal legal, architectural, surveying or council advice. Site-specific or borderline cases may still need checking with the local authority or a qualified specialist before drawings, applications or contractor spend move ahead.
Your enquiry details are used to respond to your request. Anonymised themes may be used to improve guides, tools, FAQs and site content. Identifiable case details are not published without permission, and sending an enquiry does not sign you up to marketing emails. Privacy notice.

Helpful when refusal risk is clearly pushing the project toward a formal application route.
Open guideBoundary Rules
Useful where neighbour impact or boundary siting is driving the risk profile.

A strong next read when heritage or local character controls may tighten the planning response.
Open guideHouse Extensions
Useful for broader extension design context where scale and appearance are the main issues.

Best when local policy or council context could change how the risks are judged.
Open guideUse These Tools Properly
Rules vary by location
Planning routes can change by council area, property history, designations and the exact proposal. Use this page as a structured guide to the next check, not as a blanket approval.
What this page is for
To reduce uncertainty quickly, point you to the next page that matters, and show when a broad tool result is still too weak to rely on for a live project decision.
What it does not replace
These tools do not replace formal confirmation for borderline schemes, local authority checking where special controls apply, or paid specialist input for genuinely complex cases.
How the guidance is built
Tool results are based on common planning and permitted development baselines, then framed to push you toward the project, local authority and rule pages most likely to settle the remaining doubt.
When to stop relying on broad guidance
Escalate when the route only works inside a tight threshold, when local controls may be doing most of the work, or when you need written certainty before drawings, applications or contractor spend.
Safest formal next step
Use the tool result as triage, then move into the matching guide. If certainty still matters, step up to a lawful development certificate, pre-application advice or professional help rather than rerunning broad checks.
