Blocked Drain Clearance across the UK
A slow-draining sink, gurgling toilet or foul smell from the gully is rarely just one blockage.
Blocked drain clearance in the UK costs £80–£150 for a standard sink or shower unblock. Whole-house drainage problems requiring CCTV survey and high-pressure jetting run £200–£500. Call a specialist when multiple drains are blocked simultaneously or there is sewage smell.

Common causes of blocked drains in UK homes include fat/oil build-up in kitchen waste pipes, hair and soap scum in shower traps, wet wipes and nappies in soil pipes, root ingress through cracked clay pipes, and collapsed Victorian sections in older properties.
A drainage specialist will normally start with a CCTV survey to identify the location and type of blockage, then clear it with high-pressure water jetting or mechanical rodding. Stubborn root ingress may require descaling or a no-dig liner repair.
If multiple drains are blocked at the same time — sink, bath and toilet — the blockage is downstream in the main soil pipe or sewer connection. That moves the responsibility for the repair from you to either Thames Water / your regional water board, or to a shared private sewer.
