Pre-sale or lease enquiries
Investigating and cleaning up contaminated sites is expensive.
If you are involved in buying, selling, leasing or valuing land, we advise you to include site contamination searches as part of your enquiries.
This can be done by:
- Searching our Contaminated Sites Database to check if contamination has been confirmed at the property (this information is also available via a Landgate property interest report). If the online search returns ‘no matches found’ or the Landgate report returns ‘nil report’ it does not mean the property is uncontaminated.
- If nil return/no matches from step 1, submit a Form 2 to us to find out if the site has been reported as a known or suspected contaminated site and if investigation or clean-up is required.
Only information on sites with known contamination is available online (about 700 sites). Submit a Form 2 to us to search the full reported sites register of more than 4,600 sites.
The chart below illustrates the proportion of reported sites available via the online Contaminated Sites Database or Landgate property interest report.
Basic summary of records (BSR)
A basic summary of records describes the nature and extent of known and suspected contamination affecting the land and/or groundwater.
It also provides information on applicable restrictions such as on building construction, abstraction of groundwater or when undertaking intrusive maintenance works due to the presence of contamination.
