About these reports
Contaminated land report. A contaminated land report, usually called a Phase 1 desk study or preliminary risk assessment, checks whether past uses of a site could have left pollution in the ground that might harm future residents.
Percolation and soakaway tests. A percolation test measures how quickly water drains away into the ground on your site.
Flood risk assessment. If your site is in or near a flood zone, or is a larger development anywhere, your council will usually ask for a flood risk assessment before granting planning permission, alongside a drainage strategy showing how surface water will be managed.
