What drainage in Oxford actually looks like
Your water company
Thames Water serves Oxfordshire and the Thames Valley. It's responsible for public sewers and the lateral drains beyond your boundary — including build-over agreements.
Who's responsible? →Local ground conditions
Oxford sits on clay-influenced ground — often poor for soakaways and a higher risk for subsidence and root ingress. A percolation test decides.
Soakaway rules & costs →Local housing age
Oxford has a high share of Victorian and Edwardian terraces. Older clay drains here are prone to cracks, displaced joints and root ingress — what a CCTV survey pinpoints.
Why drains keep blocking →When to book
Blockages spike in December–January as festive fat and wipes hit the sewers (Water UK). Autumn is the best time to survey — before winter rainfall raises the risk of flooding and backing up.
