Clear Environmental works with developers, architects and planners across Greater London to provide clear, planning-ready environmental reports that help you secure permission, protect future occupiers and avoid costly surprises during construction.

Why Are Environmental Reports Important in London?
From historic industry and wartime bombings to deep made ground and sensitive water environments, London sites often present unique geo-environmental challenges.
Key local factors include:
- Former industrial uses across boroughs like Newham, Tower Hamlets, Greenwich and Southwark
- Widespread made ground and infilled land with potential for ground gas risks
- Unexploded ordnance risks in areas affected by WWII bombing
- Shallow groundwater and proximity to controlled waters including the Thames and its tributaries
- Borough-level planning policies that require contamination risk assessments and mitigation
Most London boroughs require a Phase 1 Preliminary Risk Assessment as part of planning applications for brownfield redevelopment, residential conversions or basement excavations. If contamination or risk is identified, a Phase 2 intrusive investigation is often required, followed by a remediation and verification strategy.

FAQs About Geo-Environmental Reports
Do I need a Phase 1 Environmental Report for planning in London?
Yes. Most London boroughs require a Phase 1 Desk Study as part of planning applications involving redevelopment, change of use, or basement excavation—especially on brownfield land.
What are common contamination risks in London?
London has a long industrial history, so contamination risks include hydrocarbons, heavy metals, asbestos and ground gas. UXO (unexploded ordnance) and deep made ground are also common in central and East London.
How long does it take to get a Phase 1 or Phase 2 report in London?
We typically deliver Phase 1 Environmental Reports within 10 days. Site Investigations and lab analysis for Phase 2 reports usually take 4–6 weeks depending on scope and access. Fast turn arounds are available on request.
