Building Control Route Checker
Use this when planning and building regulations are starting to blur together. It gives a practical route steer before you contact building control, book a contractor, or assume an installer certificate will be enough.
Check The Building Control Route
Answer the project, work stage, planning status and evidence questions. The result points to the building-control conversation most worth having next.

What This Tool Is Good For
What it answers well
It helps separate ordinary pre-start building control, competent person certification, regularisation and planning-first situations.
What it does not decide
It does not approve the work, replace your building control body, or prove that planning permission is unnecessary.
Best next move
Open the matching building regulations guide, then ask building control or the registered installer exactly what evidence will exist at completion.
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 building control route checker a final answer?
No. The checker narrows the building regulations route to discuss next, but it does not approve work, replace building control, or prove that planning permission is unnecessary.
What details most often change the result?
The stage of the work, the amount of structural or fire-safety work, whether installer certification applies, and whether planning is already settled are the details most likely to change the result.
When should I verify formally?
Contact building control or a registered installer before work starts, and urgently if work has already started or completion evidence is missing.
What page should I open next?
Open the matching building regulations guide first, then ask exactly which route, inspections and certificates should exist.
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
- Building control route checker
- Building notice or full plans?
- Do I need building regulations approval?
- Competent person scheme or building control?
- Regularisation certificate checker
How This Tool Fits Building Regulations Work
Building Control Route Checker is a triage tool for England building regulations and building control questions. It is designed to help you ask a better next question, not to approve work or replace the building control body.
Use the result to decide whether the next step is full plans, building notice, competent person certification, regularisation, or a planning-first pause. Keep the planning route separate, because building control does not decide whether the development itself needs planning permission.
Need Help Separating Planning From Building Control?
If the route checker shows that planning, building control, certification or missing evidence are tangled together, use the structured guidance form to frame the next practical question before spending more.
Best for
Borderline, awkward or site-specific cases where the guides have helped, but the answer still turns on facts unique to your property or proposal.
What the reply aims to do
The reply aims to narrow the likely route, flag the details that matter most, and tell you which verification step is safest before more money goes into the project.
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.

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 general 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.
