Get StartedUnderstanding Sunbury-on-Thames’s Build Over Requirements
Where a Sunbury-on-Thames project involves building over or within close proximity to a public sewer, Thames Water needs to formally approve it, a genuinely separate process from planning permission, running alongside it rather than replacing it.
A CCTV survey of the existing sewer is sometimes required as part of this in Sunbury-on-Thames, though not always, it depends on how well documented the sewer’s exact route and condition already are. We arrange one where it’s genuinely needed, not as a blanket extra.
We keep Sunbury-on-Thames clients clear on the distinction, Thames Water’s build over approval and planning permission are two separate, real requirements, and missing either causes genuine problems later.
