How much does Drain unblocking & drainage cost in Swansea? (2026 price guide)

Clearing a single blocked drain typically costs £80-£180 for a straightforward callout, while more stubborn blockages requiring high-pressure jetting usually run £150-£300. CCTV drain surveys generally cost £100-£250, and full drain repairs or relining after damage is found can range from £300 up to £2,000 or more depending on the extent of the work.

Prices vary mainly with how accessible the blockage is, the length and depth of pipework affected, whether the problem is a simple clog or a structural issue such as a collapsed pipe, and whether the callout falls outside normal working hours. Emergency out-of-hours visits typically carry a premium over booked daytime appointments.

Asking for a CCTV survey before agreeing to repair work helps confirm the actual cause and avoids paying for unnecessary excavation.
