Our team of trained engineers use advanced tools and methods to diagnose and clear blockages safely, restoring your home’s plumbing to perfect working order.
In this comprehensive guide, we’ll explain how to identify the early signs of a blockage, simple DIY steps to try, when to call in professional help, and how to prevent future drain issues from happening again.
Common Causes of a Blocked Drain in London
Before you can fix a blockage, it’s helpful to understand what’s causing it. London’s mix of old housing, tree-lined streets, and ageing infrastructure makes drain blockage a frequent problem.
A blocked drain in London can be caused by anything from everyday waste buildup to structural damage underground. Let’s look at the most common culprits.
Everyday Household Waste
The majority of drain blockages start indoors. In the kitchen, cooking oils, fats, and food debris often end up going down the sink, where they solidify and cling to pipe walls. Over time, this buildup reduces water flow, leading to sluggish drains or complete blockages.
In the bathroom, hair, soap scum, and toothpaste residue are common offenders. When mixed, they form stubborn clogs that are difficult to remove without professional equipment.
Outdoor Factors
Leaves, mud, and debris from your garden can easily block outdoor drains, especially during heavy rainfall. Tree roots are another major problem in older London properties; they can infiltrate underground pipes, crack them, and cause significant structural blockages.
Structural Problems
Sometimes the issue isn’t debris at all. Cracked, collapsed, or misaligned pipes can restrict water flow and cause backups. Older homes are particularly prone to these problems, as decades of wear and soil movement take their toll.
How to Diagnose a Blocked Drain
Before calling in the experts, it’s worth checking whether the problem is something you can identify yourself.
There are several telltale signs that indicate you may have a blocked drain in or around your property.
Signs You Have a Blocked Drain
- Slow draining sinks or bathtubs – water lingers for longer than usual.
- Gurgling sounds from pipes or plugholes – air trapped in the system.
- Unpleasant smells – usually from decaying organic matter stuck in the drain.
- Water backing up – especially in sinks, toilets, or showers.
If you notice multiple drains in your home are affected at once, this suggests the blockage is in the main sewer line rather than an individual pipe.
Simple Tests You Can Try
- Check multiple fixtures: Flush the toilet and run taps simultaneously. If water backs up or drains slowly everywhere, it’s a main drain issue.
- Inspect outdoor drains: If accessible, lift the drain cover and look for standing water or visible obstructions.
- Use a torch or camera: For visible internal pipes, you might spot buildup or leaks near the joints.
If these signs persist or worsen, it’s best to call professionals like Speedy Jet Plumbers for a thorough CCTV drain survey to pinpoint the exact issue.
DIY Steps to Clear a Blocked Drain
You can often resolve minor blockages using simple household methods. These are safe, cost-effective, and easy to try before booking a professional visit.
1. Boiling Water Flush
Sometimes, grease and soap buildup can be loosened with boiling water. Pour it slowly down the drain in stages, allowing a few seconds between each pour. This can dissolve softer deposits and help restore flow.
2. Baking Soda and Vinegar
Mix one cup of baking soda with one cup of white vinegar and pour it down the drain. Leave the mixture to fizz for 10–15 minutes before rinsing with hot water. The chemical reaction helps break down organic material and deodorise the drain.
3. Plunger Method
A simple plunger can often dislodge minor clogs in sinks and toilets. Create a tight seal over the drain and use firm, rapid strokes. The suction and pressure help push the blockage through the system.
4. Drain Snake or Rod
If you have access to a drain rod or flexible snake, insert it carefully into the pipe and twist it to hook and remove debris. This method is especially effective for blockages close to the surface.
5. Avoid Chemical Cleaners
While chemical drain cleaners promise quick results, they often cause more harm than good. These corrosive substances can weaken pipes, damage seals, and harm the environment.
If these DIY methods don’t resolve the issue, the problem likely lies deeper in the system. That’s where professional drain cleaning in London comes in.

Preventive Maintenance Tips for Clear Drains
Preventing blockages is easier and more cost-effective than dealing with them after the fact. Here are some practical ways to keep your drainage system running smoothly all year round.
Dispose of Waste Properly
Never pour fats, oils, or grease down the sink. Once cooled, they solidify and narrow the pipe. Dispose of them in sealed containers with your regular waste instead.
Install Drain Guards
Mesh drain guards are inexpensive and effective. They trap debris like food scraps and hair before they can enter your pipes.
Flush Drains with Hot Water Weekly
A simple weekly flush of hot water helps prevent soap and grease from solidifying in your drains, maintaining steady flow.
Book Regular Professional Cleaning
Scheduling routine drain cleaning in London with Speedy Jet Plumbers ensures long-term peace of mind. We recommend annual maintenance for most households to keep pipes free of buildup.
CCTV Drain Surveys for Older Properties
If your home is over 30 years old, regular drain surveys can help detect cracks, leaks, or root intrusion before they cause major damage.
