A planning application can help you understand what is being proposed, but it is easy to read more into it than the record supports. Treat the first review as an information check: identify the proposal, establish what is current and note what you still need to know.
This is a research checklist, not planning, design or construction advice.
Confirm the application identity
Start with the council, reference and proposal description. Make sure the record you have opened is the one you intended to research. Similar descriptions, neighbouring properties and later amendments can make a quick scan misleading.
If you need the original register, use GOV.UK's council planning-register finder. Record the source link and the date you checked it in your own working notes.
Separate dates with different meanings
An application date, a council publication date, a decision date and the date a lead source found a record describe different events. None is an agreed construction start date.
When comparing two records, check which date is being used. A recently discovered item might relate to an older application. A recent decision might concern a proposal that has already been under consideration for some time.
Read the description, then verify the detail
The description tells you what to investigate. It may not describe every aspect of the work or its latest revision.
Read the available drawings and supporting material relevant to your question. Note drawing titles, dates and revisions where shown. Do not mix an older plan with a later description and assume that they form one current package.
If material is missing or unclear, record that limitation. A missing detail is a question to resolve, not an invitation to infer a specification or construction method.
Check the current position on the source register
Look for the application's current status and any decision material that is available. Read the actual document when it matters, rather than relying on a short status label copied elsewhere.
Planning position and construction readiness are separate questions. A decision does not tell you that finance, appointments, technical requirements or the owner's programme are settled. Our guide to planning stages explains how to keep those questions separate.
Ask a narrow business question
Your first question might be: “Does this proposal resemble the extension work our team wants in this area?” That is more useful than trying to establish everything in one sitting.
If the answer is no, stop and record a brief reason. If the answer is possibly, identify the one or two unknowns that determine whether more research is justified. Do not produce an early quotation simply because a drawing is available.
Keep a short review note
Use this structure in your existing business system:
| Field | What to write |
|---|---|
| Source checked | Council record link and review date |
| Proposal | A factual summary of the published description |
| Document position | Relevant documents viewed and any uncertainty over revisions |
| Fit | Why the scope and area might suit your business |
| Unknowns | Questions the record does not answer |
| Decision | Investigate further, revisit or set aside |
Avoid copying unnecessary personal details into your notes. The purpose is to support a proportionate decision, not to duplicate the entire register.
Use the app as a starting point
Trade Watch Alerts helps surface selected extension-related opportunities in covered areas. Available details depend on what the councils publish. The app does not turn a proposal into a customer instruction or replace the source check.
After this review, use the extension qualification checklist to decide whether the project merits more time. If you are still exploring the product, check coverage and try the app preview first.
