What blocked-drain calls in Chester actually look like
Chester blocked-drain work is a mix of complex historic drainage in city-centre conservation properties, wet-wipe blockages in Upton and Vicars Cross family homes, and root-invaded clay laterals in older Blacon and Saltney stock.
Where your responsibility ends: Chester conservation properties often have complex historic drainage runs; Upton and Vicars Cross suburban stock has single-property laterals.
When a Chester blocked drain becomes United Utilities's problem
Drainage undertaker for Chester: United Utilities
Under the 2011 private-sewer transfer, any pipework serving more than one property, and any lateral drain from the boundary of your property to the sewer, is United Utilities' responsibility. That covers most back-alley shared runs and every stretch under the public highway. Some Chester city-centre streets still have UU-adopted Victorian combined sewers — 0345 672 3723 for adopted-main issues.
United Utilities 24/7 sewer-flooding line: 0345 672 3723 — free of charge. Call them first if the blockage is beyond your boundary or on shared pipework.

How Kevin approaches a blocked drain in Chester
- Photograph access and drainage-run positions before quoting on conservation properties

- CCTV-survey any repeat blockage
- Rod the customer's chamber first before jetting shared runs
- Log the UU case number on shared-lateral clearances

Why you shouldn't be sold an excavation in Chester without a camera survey
Chester conservation-property owners get quoted eye-watering "heritage" prices for standard drainage work. There is no premium for period-property drainage — access adds labour time, not a heritage surcharge.
Our promise on every Chester blocked-drain call-out: £50 to attend and diagnose, a fair fixed quote in writing before any billable clearance or repair, and the £50 refunded if we can't clear the blockage we diagnosed.
