What information is needed for planning pre-application advice?

Before seeking planning pre-application advice, many homeowners and buyers are unsure what information is required and how prepared they need to be.

At early stages, advice does not rely on detailed drawings. Instead, it focuses on understanding the site, context, and intentions clearly enough to assess feasibility and risk.

Information typically needed at pre-application stage

Pre-application advice can usually be provided using a combination of readily available information, including:

Property address and location - The full address allows planning history, policy context, and constraints to be reviewed.

Site photographs - Recent photographs help establish scale, context, and relationship to neighbouring properties.

Outline description of intentions - A brief explanation of what you are considering — such as an extension, alteration, or change of use — is usually sufficient at this stage.

Planning history (if known) - Any previous planning applications or refusals can help identify sensitivities, although these can often be reviewed independently.

Estate-agent particulars or existing drawings (if available) - These can assist understanding but are not essential at early advisory stage.

What is not required initially

At pre-application stage, it is often unnecessary to provide:

• Measured surveys

• Design drawings

• Detailed layouts or elevations

• Structural or technical reports

Early planning advice is intended to inform decisions before committing to this level of detail.

Why clarity matters more than detail

At early stages, clarity of intent is more important than precision. Understanding what you hope to achieve, even at a high level, allows constraints, risks, and realistic options to be assessed.

This helps avoid spending time and cost on drawings before feasibility is understood.

How preparation affects advice quality

Providing clear, relevant information at the outset allows advice to focus on:

• Feasibility rather than assumptions

• Planning risk rather than design detail

• Strategy rather than form

For buyers, understanding planning considerations when buying a house early helps ensure advice is grounded in realistic context rather than speculation.

When additional information becomes necessary

As projects progress, further information may be required, including measured surveys, design proposals, and technical details. These are typically commissioned once feasibility has been established and decisions are made to proceed.

Separating advice from design helps ensure each stage is approached appropriately.

Preparing for effective advice

Effective pre-application advice does not require a fully defined project. It requires sufficient information to understand context, intention, and constraints.

Starting with the right level of information helps advice be focused, timely, and useful.
