Reading your decision notice

Read the entire decision notice, not just the word “approved”: it identifies the authorised development, conditions and important dates. Check it against the approved drawing revisions and any associated obligations before treating the project as ready to build. [1][2]

Confirm what has actually been decided

Start with the application reference, site, description and decision date. Check whether the notice grants permission, refuses it or approves a particular later detail rather than the original development. The planning register is the place to retrieve the relevant decision and documents. [1][3]

Keep separate decisions separate. For example, a letter approving details under a condition should not be mistaken for a new permission for a larger scheme. Build a simple chronological index of the permission and subsequent approvals.

Identify the approved plans

Find the drawing numbers and revisions referred to in the permission and its conditions. Compare those with the set held by the designer and builder. Later changes must be addressed through the appropriate planning route rather than assuming any newer drawing supersedes an approved one. [2]

Where the document list is unclear, ask the council for clarification before ordering or building an affected element. A practical drawing register should distinguish submitted, superseded and approved versions.

Turn conditions into a programme

Read every condition and its reason. Some control the development directly; others require details to be submitted and approved at a specified stage. A condition requiring approval before commencement is different from one requiring compliance before occupation or throughout the use. [4][5]

For each condition, record the trigger, required action, person responsible and evidence of completion. Include any continuing restriction in the handover information. Do not mark a condition finished merely because an application for details has been sent.

Understand informatives

Informatives provide advice or draw attention to other matters; they are not themselves planning conditions. However, they can alert you to separate permissions or obligations that still need addressing. Read them rather than assuming they are irrelevant because they sit at the end of the notice. [1]

Planning approval and building regulations approval are distinct. An informative referring to building control is not a technical approval or a substitute for the relevant building control process. [6]

Check dates and unresolved restrictions

The notice's commencement condition matters. Do not calculate the last lawful starting date from the upload date of a drawing or from a committee meeting when the written permission gives a different date. The council's published guidance explains the need to work within the permission's stated period. [7]

If a condition appears unworkable, obtain advice on the appropriate amendment or appeal route promptly. Keep the original notice intact, with later decisions alongside it, so the project's approval history remains understandable to the construction team and a future owner. [2][4]
