Drain unblocking in the UK typically costs between £80 and £300+, depending on the severity of the blockage, location, and whether specialist equipment such as high-pressure jetting or CCTV drain inspection is required.
While some companies advertise extremely low “£20–£50 drain unblocking” offers, these are often introductory call-out prices designed to get technicians on-site before additional work is quoted.

⚠️ Why Cheap £20–£50 Drain Unblocking Ads Are Misleading
Many low-cost offers only include a basic inspection or minor rodding. Once the technician arrives, additional costs may apply for:
- High-pressure jetting (£150–£250)
- CCTV drain surveys (£100–£300+)
- Root removal or pipe investigation
- Excavation or access work
📹 When CCTV Drain Surveys Are Required
If a blockage is recurring or deep within the system, a CCTV inspection is often required to diagnose the issue. This can reveal collapsed pipes, root ingress, or severe fatbergs.
CCTV drain surveys typically cost £100 – £300, rising to £500+ for full mapping reports.
