Planning Route Check
Use the Planning Route Check when you want a calm first steer before spending money on drawings, applications or contractor conversations. It gives an instant result without asking for contact details, then offers an optional help request only after the guidance has been shown.
Run The Planning Route Check
Answer the project, property, location and restriction questions. The result is general guidance only and should be checked with your council or a suitable professional where the project is restricted or borderline.
What This Tool Is Good For
What it gives you
A likely planning route, confidence level, reasons, watch-outs and next steps based on the answers you provide.
What it does not do
It does not make a legal decision or guarantee that permission is or is not required for one exact property.
When to ask for help
Use the optional help request when the result points toward restrictions, drawings, a formal application, highways approval or professional review.
Questions People Usually Ask Before They Rely On A Route Check
Use these answers to keep the result in proportion before you spend money on drawings, applications or building work.
Is this a legal planning decision?
No. It is a practical route check to help you understand the likely next step. Councils, lawful development certificates and formal advice are what settle site-specific questions.
Can permitted development still need checks?
Yes. Even where permitted development may be possible, measurements, previous additions, Article 4 directions, conservation areas and building regulations can still matter.
What if my home is in a conservation area?
Treat the result more cautiously. Conservation areas can restrict normal permitted development, especially visible changes, roof alterations, demolition and frontage works.
Do flats have permitted development rights?
Flats and maisonettes usually have fewer householder permitted development rights than houses, so council or professional checks are often sensible before relying on a simple route.
Do I need a planning consultant?
Not always. A consultant or architectural designer is more useful where the project is restricted, close to a limit, listed, locally sensitive, refused before, or likely to need drawings and a formal application.
What happens if I request help?
UK Planning Guide may contact you about the enquiry and, only if you consent, may share it with a relevant planning, design or home-improvement professional if suitable help is available. A match is not guaranteed.

How This Tool Fits Into The Wider Planning Process
Planning Route Check 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 route check 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.

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.
