Drainage Build Over Agreements in
Oxford
Extending over or near a public sewer in Oxford needs approval from Thames Water, entirely separate from planning permission itself. Getting the structural detail right the first time keeps this fast, without cutting corners.
Get StartedWhat Thames Water Actually Needs To See For Oxford
Getting Thames Water’s approval for a Oxford build over agreement means submitting real structural detail, not just a general description, showing exactly how the foundation design accounts for the sewer’s presence.
For some Oxford projects a CCTV survey forms part of that submission, for others it doesn’t, Thames Water’s requirement depends on the individual site. We’re upfront about which applies before any work starts.
This approval runs alongside your Oxford planning permission, not instead of it, both are genuinely needed for a project that involves building near a public sewer.

How We Help in Oxford
Oxford cases begin with a proper look at the site and the sewer route, not an assumption based on how straightforward the project seems.
What follows addresses exactly what Thames Water needs for Oxford, structural detail, design detail, and a CCTV survey where it’s genuinely required.
Given how much attention to detail Thames Water expects for a Oxford build over approval, we stay engaged throughout, right up to a decision.
Why Oxford Projects Get Thames Water’s Attention Right
Every Oxford submission to Thames Water gets checked properly before it goes in, since a poorly prepared application slows down the fast turnaround we’re aiming for.
Being honest about whether a Oxford project needs a CCTV survey, rather than assuming either way, keeps both cost and timeline realistic.
Whatever a Oxford project actually involves, structural detail, design detail, or both, we prepare it properly for Thames Water from the outset.
