Get A Practical Plain-English Steer On Your Specific Planning Question

If your case feels too specific for a broad guide but too early for expensive formal work, this is the light-friction next step. Start with the form and get a tailored steer by email on the likely route, what may change it locally and what to verify next.

Best for

Projects that feel too specific for a broad guide yet too early for formal submissions or a full professional appointment.

What the reply aims to do

The reply aims to give a practical informational steer on the likely route, the local or site details most likely to change it, and the safest next move when certainty matters.

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.

Who it is for

Useful When The Real Question Is Specific, Borderline Or Locally Sensitive

Useful for homeowners

Helpful when you want to understand the likely route for an extension, loft, outbuilding, frontage change or other domestic project before the costlier stages begin.

Useful for awkward edge cases

Especially useful where previous additions, listed status, conservation-area context, flats, maisonettes, or local sensitivities may change the broad answer.

Useful before you spend more

Best used as a practical early steer so you can decide whether the next move is more reading, a certificate, a council check, a redesign or formal specialist input.

Structured request form

The Main Route For A Case-Specific Planning Question

Use the form when you want a cleaner enquiry route than a mailto link. It captures the facts that usually decide whether the next step is broader guidance, a clearer case-specific steer or a stronger formal check.

Keep it concise. The most useful summary is usually the project, the rough dimensions and the part that feels uncertain or risky.

How this works: This guided form is the main route for case-specific planning questions. It captures the key facts cleanly before you move into a reply or a stronger formal check.

Useful details to include

  • Property type.
  • Council or local authority area.
  • Town or location.
  • What you want to build or change.

What you will get back

A Practical Reply That Helps You Spend Money In The Right Order

Likely route

A plain-English steer on the likely planning route, including where the answer still looks routine and where it starts to tighten.

What may change it locally

The local designations, authority context or property details most likely to move the answer away from the broad national baseline.

Best next steps

The main tripwires to verify next, the checks worth doing before you pay for more work, and when formal confirmation starts to look worthwhile.

Clear limits

What This Can And Cannot Do

What it can do well

  • Review the details you send and give a case-specific plain-English steer.
  • Highlight the likely planning route and the local or site details most likely to change it.
  • Help you decide what to verify next before you spend more money.

What it cannot do

  • Confirm a planning outcome or guarantee that permission is or is not required.
  • Replace formal legal, architectural, surveying or council input.
  • Override local authority records, property history or site-specific facts that still need formal checking.

When formal verification is worth it

  • The proposal is close to a limit.
  • The site is listed, in a conservation area or may be affected by Article 4.
  • The financial or timing consequences of getting the route wrong are meaningful.

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.

Trust and method

What This Guidance Is For And Where It Stops

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 give a case-specific informational steer once a broad guide has narrowed the question but the live answer still depends on the proposal details, the site or the local authority context.

What it does not replace

It does not replace a council decision, legal advice, architectural design advice, surveying advice or any formal confirmation needed for a borderline or high-stakes scheme.

How the guidance is built

Replies are framed around the details you send, the same national and local planning logic used across the site, and the public information needed to identify the most likely tripwires and next checks.

When to stop relying on broad guidance

Stop relying on this guidance alone when the route depends on a tight threshold, a sensitive site, uncertain planning history or a decision you would not want to revisit after paying for drawings or works.

Safest formal next step

Use a lawful development certificate when the scheme appears lawful but certainty matters. Use pre-application advice or formal professional input when local judgement, heritage controls or design complexity are doing most of the work.

Official-source check

Where this page shows official sources, use those links near the relevant answer to confirm the latest council or national wording before relying on a borderline route.

When to verify formally

Situations Where This Guidance Should Lead To A Stronger Formal Check

Close to a threshold

If the route only works because a measurement, height, volume or siting point stays inside a tight limit, measured drawings and formal confirmation are usually worth it.

Heritage or special controls

If listed-building issues, conservation-area context, Article 4 coverage or similar controls may be doing most of the work, the safest route is to verify the exact property position rather than assume.

Meaningful cost risk

If getting the route wrong would create wasted fees, a redesign, delays or a poor submission strategy, treat that as the point to step up into formal checking.

Common questions

What People Usually Want To Know Before They Submit A Request

Keep this block for the trust, scope and response-time questions that usually come up once the service looks relevant.

What happens after I submit the form?

The case details are read and used to frame a practical reply about the likely route, the local tripwires and the next checks worth making, with the response sent by email.

What details should I include?

Send the property type, local authority area, town or location, what you want to build or change, the approximate size or position, any heritage or flat-related constraints, previous additions, and the main thing worrying you.

Is this formal advice?

No. It is informational personalised guidance based on the details you provide and publicly available information, not formal legal, architectural, surveying or council advice.

Can you tell me if I definitely need permission?

No one should promise that from a short email alone. The aim is to give a practical steer on the likely route, the local or property details most likely to change it, and the next checks worth making.

When should I skip this route and go straight to a specialist?

Do that when the project is urgent, already at a formal stage, or too high-stakes to leave on an informational steer before formal checking.
