What drainage in Slough actually looks like
Your water company
Thames Water serves Berkshire 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
Slough 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
Slough has a mix of older and newer housing, so drain age and material vary. A CCTV survey confirms the condition of whatever drains your property has.
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.
