A Phase 2 Ground Investigation uses intrusive fieldwork, sampling and testing to verify and quantify contamination and ground risks identified at desktop stage or through planning review.
When this service is used
Used to discharge contaminated land planning conditions, investigate risks identified by a Phase 1 Desk Study, support land acquisition and due diligence, and provide measured ground data for remediation or development design.
What the report normally includes
- Site-specific investigation and sampling plan
- Trial pits, boreholes or other intrusive techniques as scoped
- Soil, groundwater and ground gas sampling where required
- UKAS-accredited laboratory testing where appropriate
- Interpretation of chemical and geotechnical results
- Updated Conceptual Site Model and quantified risk assessment
- Recommendations for remediation, further investigation or design inputs
What we need from you
Providing the right information at the start helps us confirm the scope, quote accurately and avoid back-and-forth once the work is underway.
- Site address and red-line boundary plan
- Phase 1 Desk Study and previous reports where available
- Planning condition wording or regulator comments
- Proposed development layout and current site use
- Access constraints, services information and investigation deadline

Common questions
What is a Phase 2 Ground Investigation?
It is an intrusive site investigation using techniques such as trial pits and boreholes, with sampling and testing to measure ground, contamination, groundwater or gas conditions.
Do I need a Phase 1 first?
Usually the Phase 2 scope is informed by a Phase 1 Desk Study, planning condition or other preliminary risk assessment so investigation targets the relevant potential pollutant linkages.
What happens after the investigation?
Results are interpreted in an updated Conceptual Site Model and risk assessment, with recommendations for remediation, monitoring, further investigation or development design where required.
