Drainage and water searches from Thames Water Property Insight
Get the whole picture from Thames Water Property Insight.
Buying a house is probably the biggest investment you’ll ever make, so it pays to look at the bigger picture to avoid any potential risks in relation to water and sewerage services that can sometimes have a direct impact on property value and maintenance costs.
Residential properties
The residential drainage and water enquiry (CON29DW) can provide answers to the following types of questions:
- Is the property connected to a public sewer or is it served by a cesspit, for which I will be responsible?
- Where do the sewers run and who is responsible for them? Will any plans to extend the property be affected by the route of a public water main or sewer?
- Is there a history of sewer flooding affecting the property?
- Does the property have a 'Building Over Agreement' for an extension that is built over a public sewer or manhole? If not, what are the implications?
- Does the property have low water pressure and could this affect the performance of a power shower or garden hose?
- Will the water company install a water meter at the property after I move in?
For absolute peace of mind ask your solicitor to obtain a CON29DW Drainage and Water Enquiry when carrying out the conveyancing on your new property.
Commercial properties
For commercial properties, our Commercial Drainage & Water search includes everything that the residential CON29DW offers, such as connection status, water quality, basis of charging and location of pipes.
