What Does Drain Clearance Actually Cost? 2026 Price Breakdown
One of the most common questions we get at Drain Review is: "How much should I pay to get a blocked drain cleared?" The answer depends on the type of blockage, your location, and the company you choose. Here's a straightforward guide to what you should expect to pay in 2026.
Standard blocked drain clearance
| Service | Typical Cost | Notes |
|---|---|---|
| Basic drain rodding | £80–£150 | Simple blockage, single drain |
| High-pressure water jetting | £150–£250 | Most common professional method |
| CCTV drain survey | £150–£300 | Camera inspection to diagnose problems |
| Emergency call-out (evenings/weekends) | £200–£350 | Premium for unsociable hours |
| Drain repair (localised) | £300–£600 | Patch repair or relining |

Prices are indicative and based on our research across companies listed on Drain Review. Actual costs vary by location and complexity.
What affects the price?
- Severity of blockage: A simple sink blockage costs less than a main sewer line blockage that requires heavy machinery.
- Location: London and the South East tend to be 20–30% more expensive than the Midlands and North.
- Access: If the drain is difficult to reach (under a patio, in a basement, etc.), expect to pay more.
- Time of day: Evening, weekend, and bank holiday call-outs attract a premium, typically 30–50% more.
- Root ingress: Tree roots in drains require specialist cutting equipment and multiple visits.
How to avoid being overcharged
- Get a fixed quote upfront. Avoid companies that charge by the hour or add "diagnostic fees."
- Ask about call-out fees. Many reputable companies offer "no call-out fee" — meaning you only pay if they do the work.
- Compare at least two quotes. Use Drain Review to find multiple rated companies near you.
- Check reviews first. Cheap isn't always best. A company with excellent reviews at £180 may be better value than an unknown at £120.
- Be wary of upselling. Not every blockage needs a CCTV survey. If a company pushes expensive additional services, get a second opinion.
Is it covered by insurance?
Most standard home insurance policies do not cover drain clearance as routine maintenance. However, if a blocked drain causes damage (e.g., water damage to your property), the resulting damage may be covered under your buildings insurance. Some insurers offer "home emergency cover" as an add-on that includes drain blockages — check your policy or contact your insurer.
For more detail on insurance and drainage, the Association of British Insurers has useful guidance.
Who pays: you or the water company?
If the blockage is in the pipework within your property boundary, it's your responsibility. If it's in the public sewer (beyond your boundary), it's the water company's responsibility and they should clear it free of charge. If you're unsure, your local water company (e.g., Thames Water, Southern Water) can advise which section of the drain they're responsible for.
