Phase 1: Desktop Study
Desktop contamination reports are the first step in investigating potentially contaminated land.
We’re one of the very few that produce an easy-to-understand summary.
We offer the most economic desktop study reports so that your planning condition is discharged as quickly and cost-effectively as possible.
What is a Phase 1: Desktop Study?
A Phase 1: Desktop Study is the first step in investigating potentially contaminated land. It is required by planners, warranty companies and building control officers.
Also known as a Contaminated Land Risk Assessment or Preliminary Risk Assessment (PRA), we create reports to the national standard.

How is a Phase 1: Desktop Study carried out?
Our highly trained and extensively qualified experts undertake every desktop study. We perform a site walkover during every Phase 1: Desktop Study which the local authority requires. Usually, this comes at an additional price but we include a site walkover as standard.
As well as the site walkover, we also gather information on:
- Historical mapping
- Geology in the area
- Potentially contaminative land uses, past and present
- Hydrogeology
We then create a risk assessment or Conceptual Site Model (CSM) which is used to assess any potential risk to the end-user, construction workers, groundwater or habitats.
