FAQ’S
There is a distinction between public and private sewers in terms of responsibility and service. Public sewers are the responsibility of the local water authority and serve multiple properties, whereas private sewers serve only one property and are owned and maintained by the owner.
If the conservatory is built within 3 meters of a public sewer, or over one, then you will need a build-over agreement.
In the absence of an agreement, your build could face legal, constructive, or cancellation issues during the selling phase, or during building control inspections, which could lead to inspection issues, delays, or even demolition.
You may apply directly through the Thames Water portal or acquire professional aid, as you must present precise plans alongside drainage arrangements.
Approval usually takes about 3-4 weeks but can differ based on your project’s complexity and the water authority.
With expert planners and compliant documents, it can be made relatively simple, especially for companies like Paramountbuilt, which help streamline the process.
