Phase 1 Desk Study
We provide clear, proportionate Phase 1 Desk Studies to identify potential environmental risks and land-quality constraints and to support safe, compliant development. Our assessments are prepared in line with UK guidance including CLR11, BS10175 and the National Planning Policy Framework, providing a robust evidence base for planning and early project decision-making.
What this Service Includes
- Review of historical maps and aerial photography
- Review of geology, hydrogeology and flood risk
- Environmental database searches
- Development of a preliminary Conceptual Site Model
- Identification of potential pollutant linkages
- Preliminary Risk Assessment (PRA)
- Site walkover survey (where required)
- Clear, regulator-ready reporting suitable for planning submissions
Our Approach
Our Phase 1 Desk Studies follow a structured, evidence-based methodology. Each assessment is carried out in accordance with recognised UK guidance and is designed to support clear, defensible decision-making.
Our approach includes:
Systematic review of historical and environmental records
Identification of credible pollutant linkages
Development of a robust preliminary Conceptual Site Model (CSM)
Clear justification of whether further investigation is required
Transparent reporting written in plain, accessible language
Why a Phase 1 Desk Study is Essential
A robust Phase 1 Desk Study reduces uncertainty, ensures regulatory compliance and prevents costly surprises later in the project. It provides the evidence base needed for planning submissions, risk screening and determining whether a Phase 2 investigation is required.
This early assessment protects project timelines, budgets and stakeholder confidence.
