How Much Does Drain Unblocking Cost in 2026? Prices Explained

The drain unblocking cost you will actually pay depends on the method used, the severity of the blockage, and whether the company charges a call-out fee on top. Prices online range wildly, from £49 to £300 or more, and it is not always clear what is included. This guide breaks down what we charge at Cofton DJS, how those prices compare across the industry, and what to watch out for when comparing quotes.

Drain unblocking price guide for 2026

The figures below are based on what we charge for drain unblocking work across Birmingham and the wider West Midlands, Warwickshire, and Worcestershire. Every price is fixed before we start. There is no call-out fee added on top.

• Manual drain rodding: from £100. Suitable for shallow blockages in domestic 100mm (4-inch) waste pipes, typically within 10 metres of the access point.
• High-pressure water jetting: from £150. Used for deeper, more stubborn blockages including fat, grease, and root matter. Our jetting units run at up to 4,000 PSI through a 100-metre hose.
• CCTV drain survey (standalone): from £250. A full camera inspection with a written report, pipe mapping, and condition grading. Often requested before buying a property or ahead of building work.
• Emergency call-out (evenings, weekends, bank holidays): from £180. Same fixed pricing structure, no call-out surcharge. Response within one to two hours across our coverage area.
• Combined unblock and CCTV check: from £100. When we clear a blocked drain, we include a CCTV camera check at no extra cost to inspect the pipe condition and identify the root cause.

These prices reflect the majority of domestic jobs. Commercial sites, multi-run systems, or drains requiring excavation will cost more, and we always quote on site before starting that type of work.

Why online drain unblocking prices can be misleading

Search for "how much to unblock a drain" and you will find companies advertising from £49 or £59. Those numbers are almost never the final bill. Many of the cheapest listings online come from lead-generation companies rather than actual drainage engineers. Here is how the pricing typically works with those firms:

• A low headline rate gets you to call. The call goes to a booking centre, not a local engineer.
• The £49 covers the first 15 or 30 minutes of manual rodding only. If rodding does not clear the blockage (which is common on anything deeper than a few metres), high-pressure jetting is quoted as an extra.
• A call-out fee of £50 to £80 is added on top, sometimes disclosed only after the engineer arrives.
• CCTV inspection, if offered at all, is a separate charge of £150 to £300.

The final invoice often comes to £250 to £400, which is more than you would have paid with a fixed-price local company from the start. We are based near Cofton Hackett in south Birmingham, and our pricing is set before any work begins. If we quote £150 for a jetting job, that is what you pay. No additions, no hourly rates ticking over.

What affects the cost of drain clearance

Not every blocked drain is the same job. The drain unblocking price depends on several factors that determine the time, equipment, and access required.

Blockage depth and location. A blockage sitting two metres from the inspection chamber is a ten-minute rod job. A blockage 25 metres down the run, past two bends and a junction, needs a jetting unit with a long-reach hose and possibly a camera to locate the exact point. The deeper the blockage, the more time and equipment involved.

Pipe material and condition. Older properties across the West Midlands often have salt-glazed clay pipes laid in the 1930s to 1960s. These are prone to root ingress at the joints and can fracture under ground movement. Newer builds typically use 110mm uPVC, which is smoother inside and less likely to snag debris. Clay pipe blockages tend to be harder to clear and more likely to reveal structural damage that needs addressing.

Type of blockage. Fat, oil, and grease (FOG) blockages require sustained jetting at high pressure to break up the solidified deposits. Tree root ingress may need a root-cutting nozzle before jetting can clear the pipe fully. A build-up of wet wipes or sanitary products often forms a dense plug that rodding alone cannot shift.

Access. If the only access point is a manhole under a parked car, a raised patio, or inside a cellar, the job takes longer. We occasionally need to set up a temporary access point or use a longer hose run to reach the blockage from an alternative chamber.

Rodding vs jetting: which method costs less

Manual drain rodding is the cheapest option and works well for straightforward blockages close to the access point. A set of polypropylene rods with a plunger or corkscrew head is pushed down the pipe to physically break up or dislodge the obstruction. It is quick, quiet, and effective for soft blockages like toilet paper or light debris.

High-pressure jetting costs more because the equipment is more expensive to run and maintain. A trailer-mounted jetting unit pumps water at up to 4,000 PSI through a specialised nozzle that fires backward-facing jets to propel itself down the pipe while scouring the walls clean. It clears harder blockages, removes grease build-up, and cuts through roots. Jetting also leaves the pipe in a better state than rodding alone, which reduces the chance of the blockage returning.

For most domestic call-outs, we start with rodding. If that clears the blockage, the cost stays at the lower end. If the blockage is too deep, too compacted, or caused by grease or roots, we move to jetting. Either way, you get a fixed price agreed before we switch methods.

How to get an accurate quote

Any drainage company offering a precise figure over the phone without seeing the job is guessing. What they can tell you is their fixed starting price, whether there is a call-out fee, and what is included. Here is what to ask when you ring around:

• Is there a call-out charge? If so, how much and is it deducted from the final bill?
• Does the quoted price include jetting, or only rodding?
• Is a CCTV camera check included after the blockage is cleared?
• Are you a local company or a national call centre dispatching subcontractors?
• Do you carry public liability insurance and are you listed on Checkatrade or a similar verified platform?

We work across the West Midlands from residential streets in Solihull Town Centre to rural properties in Worcestershire. Every job gets the same approach: a fixed price quoted on arrival, no call-out fee, and a CCTV check included with every unblock.

Is it worth paying more for a drainage engineer?

The average cost of a drainage engineer is higher than a general plumber or a handyman with a set of rods. That difference pays for specialist equipment (jetting units, CCTV cameras, root cutters), correct diagnosis, and a fix that lasts. A plumber can often clear a simple internal waste pipe blockage, but underground drainage is a different trade entirely.

We see several jobs each month where the homeowner has already paid a plumber or handyman to "clear" the drain, only for it to block again within weeks. The original blockage was a symptom. The cause, whether that is a cracked pipe, a displaced joint, or root ingress, was never identified because no one put a camera down the pipe. That is why we include CCTV with every clearance job. Finding the cause is part of fixing the problem.
