Quick rundown of drain cleaning costs

Typical service call (average cost £55)

What’s involved: A typical service call fee includes the initial inspection and minor drain unblocking procedures. This is the base price for a professional to visit you during normal hours. This service is ideal for issues that aren’t urgent but still need professional evaluation and possible minor intervention.

Emergency/after-hours service call (average cost £175)

What’s involved: An emergency or after-hours service call covers the expense of a professional visiting your location outside of working hours, i.e., evenings, weekends, and holidays. Though this service normally costs more than a typical call out, it delivers peace of mind in urgent situations where drain blockages are causing immediate problems.

Locally-targeted unblocking of sinks, toilets, or baths (average cost £60)

What’s involved: This service deals with unblocking a specific drain, like a sink, toilet or bath. It’s generally charged at a fixed rate and includes the cost of materials and labour needed for internal drain unclogging.

Drain jetting (average cost £180)

What’s involved: Drain jetting, or high-pressure water jetting, utilises a forceful stream of water throughout your drainage system to remove blockages from pipes. This drain cleaning method is incredibly useful for eliminating stubborn debris and is a fast and effective way to clear blocked drains.

Drain rodding (average cost £75)

What’s involved: Drain rodding involves applying flexible drain rods (or drain snakes)  to eliminate blockages from the drain pipes. A drain snake is perfect for shorter or minor blockages.

Drain rodding and jetting (average cost £270)

What’s involved: A combination of rodding and jetting offers a comprehensive solution for severe blockages and is a “belt and braces” approach to tackling a drain blockage.

Basic CCTV blocked drain assessment (average cost £160)

What’s involved: A basic CCTV drain survey involves using a high-definition camera to check the condition of your drain pipes. This service can help identify potential issues or damages causing blockages.

Full surveillance using CCTV for drains, including detailed report (average cost £275)

What’s involved: A step up from a basic assessment, a full CCTV drain assessment provides a more extensive analysis of your drain system’s state. The full drain cctv survey cost includes a comprehensive report with recorded footage and recommendations for any required repairs or maintenance.

Drain Relining per linear metre (average cost £100)

What’s involved: Drain relining is a trenchless technique for repairing damaged drains. This method essentially fits a new lining inside the existing pipe, restoring its functionality without the need for digging. Drain lining cost is usually charged per linear metre allowing the price to be set based on the extent of the required relining.


How can I tell if my drain is blocked?

Common indicators of a blocked drain include:

  • Water draining slowly from sinks, showers, or bathtubs
  • Gurgling sounds from plumbing fixtures
  • Unpleasant odours coming from drains
  • Water backing up from drains or toilets
  • Localised flooding around sinks or drains

If you notice any of these signs, your drain is likely blocked and needs professional attention.

How can I prevent my drain from getting blocked?

To help prevent blockages, follow these tips:

  • Avoid pouring grease, oil, or food scraps down the drain
  • Use a hair catcher in showers and bathtubs to trap hair and debris
  • Properly dispose of non-biodegradable items like wet wipes
  • Regularly clean out sink strainers to prevent buildup
  • Schedule regular drain maintenance to catch potential issues early

By following these guidelines, you can keep your drains clear and functioning properly.

How often should I have my drains inspected?

Drains should be inspected at least once a year as part of regular maintenance. If you notice any signs of a blockage, schedule an inspection immediately.

Which service is best for drain cleaning?

The best drain cleaning service depends on the severity and cause of the blockage. For general maintenance and minor blockages, rodding or jetting may suffice. For more stubborn clogs, a combination of rodding and jetting is recommended. A CCTV drain survey can also identify underlying issues causing frequent blockages.

Can I use DIY methods to unblock my drain?

While some DIY methods can clear minor blockages, it’s best to seek professional help for severe or persistent clogs. Attempting to unclog a drain yourself may cause further damage and end up costing more. However, for minor blockages, you can try:

  • Pouring boiling water down the drain
  • Using a plunger to dislodge the blockage
  • Creating a mixture of baking soda and vinegar, letting it sit for 15 minutes, then flushing with hot water

If these methods don’t work, contact a professional for assistance.


The cost of unclogging drains varies based on the severity and complexity of the issue. Prices start from approximately £90 for straightforward manual unblocking to £275 for a complete CCTV drain assessment including a detailed report.

Additional services such as high-pressure water jetting and drain relining are charged per service or per linear metre. Drain relining averages at £100 per linear metre.

Regular drain maintenance and checks are recommended to prevent blockages, and while DIY methods can handle small clogs, experts are best for severe or persistent blockages to avoid further harm and costs.
