How Much Does It Cost to Unblock a Drain?
Have you ever wondered what happens when a drain gets blocked? Unblocking a drain can cost different amounts depending on how serious the blockage is. For simple blockages, the cost might be as low as £50. This usually happens when there’s a small clog, like food scraps or hair stuck in the pipes. However, if the problem is bigger, like tree roots growing into the drain or heavy build-ups of grease, the cost can be higher, sometimes reaching £150 or more.
The price also depends on who you call to help. Local plumbers often charge less than big companies, but some companies include extra services, like checking your drains with a camera to ensure the blockage is gone for good. The time of day can also affect the cost. If it’s an emergency at night or on the weekend, it might cost more.
So, it’s important to act quickly if you think there’s a blockage. Catching the problem early can save you money and stop the issue from getting worse.
Drain Jetting Costs
Drain jetting is a powerful way to clear tough blockages in your pipes. It uses high-pressure water to blast away dirt, grease, and even tree roots. The cost for drain jetting usually starts at around £100 but can go up to £300 if the job is very large or complex.
This method is very effective for cleaning drains that have been blocked for a long time or have tricky blockages deep down. The cost also depends on how long the jetting takes. A short job might only take half an hour, while bigger tasks can last several hours. Companies sometimes charge by the hour, so the longer it takes, the more it might cost.
Another factor is the size of the drain. Small household drains cost less to jet than larger commercial ones, which need bigger equipment and more time. Some companies also add a fee for inspecting the drains with a camera before or after jetting. This is a good idea as it helps them check that the blockage is fully cleared.
Although drain jetting may seem pricey, it’s one of the best ways to keep your drains in good shape and prevent future problems. Think of it like giving your pipes a deep clean!

Not everyone knows who should fix a blocked drain. The answer depends on where the blockage is. If the problem is in the drain pipes inside your home or in your garden, then it’s usually your responsibility to fix it. You might need to call a plumber or drainage company to help.
If the blockage is in a shared drain that connects your house with your neighbours, then it’s usually the water company’s job to unblock it. Shared drains carry waste from more than one home to the main sewer line. Water companies have special teams to handle these blockages at no cost to you.
How can you tell where the blockage is? If only one drain or sink in your home is affected, the problem is likely on your property. But if you notice several sinks or toilets backing up, or if your neighbours are having the same issue, it might be a shared drain.
It’s always a good idea to contact your water company if you’re not sure. They can let you know who is responsible and help you take the next steps.
What Are the Additional Costs of Unblocking a Drain?
Unblocking a drain can sometimes come with extra costs. For example, if a blockage is deep in your pipes, a company might need to use special tools like drain cameras to locate the problem. This can add £50 to £100 to the bill.
If the pipes are damaged, repairs might be needed. Fixing a small crack might not cost much, but replacing a section of pipe can be expensive, sometimes over £500. If tree roots have caused the blockage, removing them can also add extra charges.
Another cost to consider is emergency call-out fees. If you need help late at night or during the weekend, you might pay more for the service. Some companies also charge for cleaning up after unblocking, especially if sewage has overflowed onto your property.
To avoid surprises, ask the company about all possible costs before they start the job. This way, you’ll know what to expect and can plan accordingly.
What Can I Expect From the Drain Unblocking Process?
The process of unblocking a drain depends on the type of blockage. First, the experts will inspect the drain. They might use a drain camera to see what’s causing the problem. This helps them decide the best way to fix it.
For small blockages, they might use a drain rod. This is a long stick that can push or pull out clogs. It’s quick and works well for things like hair or food stuck in the pipes. If the blockage is more serious, they may use drain jetting. High-pressure water is sprayed into the pipes to clear away grease, dirt, or even tree roots.
If there’s damage to the pipes, the company might recommend repairs. Sometimes, they can fix small issues without digging up the ground. For larger problems, they might need to replace sections of the pipe, which can take longer.
Once the blockage is cleared, the company might inspect the drain again to make sure everything is flowing properly. They’ll also clean up any mess caused by the blockage. By the end of the process, your drain should be working like new!
