Thames Water building guidance
Building Control system changes
We are upgrading our system, and some services will be unavailable whilst we complete the work.
Applications submitted from Wednesday 29 January will not be processed until Thursday 6 February. Deadlines will be extended accordingly.
Site visits can be requested and will be processed as normal.
We apologise for any inconvenience caused.
Thames Water is responsible for maintaining public sewers, which are sometimes located within the boundaries of properties. You must get Thames Water’s agreement to carry out any building work over or within three metres of a public sewer to ensure that no damage is caused to it or restrictions made to the way we use and maintain the sewer.
For more information and to download an application form, visit the Thames Water website.
