HOW MUCH DOES IT COST TO UNBLOCK DRAINS? (UK 2026 GUIDE)

Understanding Drain Unblocking Costs

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.

💷 Average Drain Unblocking Costs (UK)

• Minor internal blockages: £80 – £150
• Main outdoor drains: £150 – £250
• Severe or recurring issues: £250 – £600+
• Emergency call-outs: +50% to +100%

📍 Regional Price Differences

• London & South East: £120 – £300+
• Midlands: £90 – £220
• North of England: £80 – £200
• Rural areas: £100 – £250+ (plus travel fees)

⚠️ 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.
