Common Questions

What does environmental due diligence cover in a property transaction?

Environmental due diligence for property transactions typically covers contaminated land risk, regulatory status (contaminated land register searches, EPA notices), environmental liabilities, planning and approval constraints, and any ongoing environmental management obligations. The scope is tailored to the transaction type—acquisitions, divestments, refinancing, and M&A each have different risk profiles and information needs.

How quickly can environmental due diligence be completed?

A desktop environmental risk review can often be completed within 3–5 business days. If intrusive investigation is required, the timeline extends to 3–6 weeks depending on site access, sampling scope, and laboratory turnaround. We regularly work within transaction timelines and can prioritise urgent instructions where needed.

Why is environmental due diligence important for buyers?

Unidentified environmental contamination can result in significant remediation costs, regulatory action, project delays, and reduced property value. Environmental due diligence identifies these risks before settlement so buyers can make informed decisions, negotiate price adjustments, or require the seller to address issues. For lenders, it protects the security value of the asset. For developers, it avoids delays during the approval or construction phase.
