CON29DW Commercial search for conveyancers

Get a report for a commercial property or land, which provides information about water and sewerage services, trade effluent, wayleaves and easements.

Asset location search

If developing or extending a property, an asset location search will provide information and maps showing the size and location of known Thames Water sewerage and/or clean water assets close to the development.

There may be lateral drains and/or public sewers which are not recorded on the public sewer map but which may prevent or restrict development of the property.

Sewer flooding history

If developing a property, this search is recommended to check if there’s been internal sewer flooding at a specific address or area, due to overloaded public sewers.
