Your No1 Simple Guide to Blocked Drains in the UK
The First Big Question Who Is Responsible for the Blockage
This is where everyone gets stuck. You see the problem but you have no idea whose job it is to fix it. The answer is actually quite simple once you know the rules. It all comes down to one thing location. You are responsible for all the pipes inside your property and the pipe that runs from your home to the point where it connects with your neighbour’s pipe or the main public sewer. This is your private sewer drain. So if you have a blocked drain outside house that only takes waste from your home the job and the bill are yours. You need to call a plumber or a drainage company.
The rules changed in 2011. This change is really important for people in terraced houses or semi detached homes. If you share a pipe with your neighbour that pipe is called a shared drain. If that shared drain blocked is causing your problem you are not responsible anymore. Your local mains sewerage provider is. Companies like Thames Water or Severn Trent own and must fix these shared pipes. So if you and your neighbour both have water backing up at the same time your first call should be to your water company. They should come and clear it for free. This answers the common search blocked sewer drain who is responsible. Knowing this law on shared drains can save you hundreds of pounds.
Spotting the Signs of a Drainage Problem Early
A full blocked sewer is hard to miss. Water comes back up into your sink or toilet. But there are earlier quieter signs that can save you from a big messy disaster. Learning to spot these early warnings is like giving your home a regular health check. The first sign is often sound. Listen for a gurgling noise coming from your toilet when you empty the bathroom sink. That gurgle is air trapped in the pipes trying to escape past a blockage. Another early sign is smell. A bad egg smell coming from your foul water drainage points like sinks or outside drains means waste is sitting and rotting in the pipes instead of flowing away.
You should also watch how water behaves. If your kitchen sink drains slower today than it did last week that is a sign. If you see water bubbling up in your shower tray when you flush the toilet that is a very clear sign of a blockage further down the line. Outside keep an eye on your storm drain or any drain cover for outside drain. If water pools there long after rain has stopped or if you notice flies buzzing around it these are warnings. Catching these small signs early means you can often fix the problem simply before it turns into a major drainage blockage that needs heavy machinery to fix.
What You Can Safely Try Yourself First
When you first notice a slow drain it is natural to want to try a simple fix. For a single blocked sink there are a few safe things you can do. The first and simplest tool is a plunger. Make sure you have a good seal around the plughole and use a firm steady pumping action. This can often dislodge a small blockage in the U bend of the pipe. Another gentle method is using a mixture of baking soda and white vinegar. Pour half a cup of baking soda down the drain followed by half a cup of vinegar. It will fizz up. Leave it for fifteen minutes then flush with a kettle full of hot but not boiling water. This can break down some organic blockages like grease or food.
For an outside drain like a blocked outside drain in your driveway you might be able to lift the drain cover for outside drain safely. Wear strong gloves. You may find a simple plug of leaves and mud that you can pull out by hand. If you can see the blockage and it is within arm’s reach you might try a drain rod to carefully poke and clear it. However it is very important to know when to stop. Never ever use chemical drain cleaners. They are dangerous. They can burn your skin. And they create toxic sludge that is terrible for the environment. If your DIY efforts do not work within one or two tries or if the problem is affecting more than one fixture in your house it is time to call a professional. Trying too much yourself can sometimes make the problem worse and more expensive for a plumber to fix later.

You should also call if you have tried simple methods and the sewer drain pipe clogged remains. If multiple fixtures in your house are blocked at the same time that points to a major blockage in your main sewer drain line.
Other urgent signs include a very bad smell that does not go away or if you notice a soggy sunken patch of ground in your garden. That could mean you have a leaking or even a collapsed drain underground. For these big jobs a professional team does not just guess. They use technology to see the problem. They push a small CCTV camera down your pipe. This lets them see exactly what is blocking it and where. It might be a build up of grease a nest of tree roots or a broken pipe.
