Regulator Engagement

Redstart believe that early engagement with the regulatory authorities is the best way to ensure the project is regulatory compliant and to ensure a collaborative approach is maintained. This pays dividends when seeking regulatory approval of the remediation verification which can often hold up land transactions if not managed properly.
