Japanese Knotweed is an invasive plant species that can cause significant damage to homes, gardens, and other structures.
If you discover Japanese Knotweed on your property, it’s important to act quickly to remove it. However, the cost of removing Japanese Knotweed can be significant.
In this blog post, we will discuss the cost of removing Japanese Knotweed and why it’s important to take action.
According to Environet UK, the cost of removing Japanese Knotweed from a single property can range from £2,500 to £20,000 ($3,500 to $28,000), depending on the size of the infestation and the method of removal.
How much does it cost to remove Japanese Knotweed?
The cost of Japanese Knotweed removal will vary depending on variables such as the size of your infestation, the location, the type of property, how quickly you need the Knotweed removed, and your future plans for the land. Herbicide treatments can be effective and cost-effective in many instances when it comes to knotweed remediation.
However, if there are plans for the property to be developed and the soil disturbed, an excavation will most likely be needed, which will cost more to remove your knotweed but will be a faster solution. As a consequence, the cost of Japanese knotweed treatment will vary.

Cost: starts from £10,000+VAT for residential gardens
Includes: excavation of ‘controlled waste’ materials & off-site disposal to licensed landfill, risk & method statements, SMSTS Qualified Site Manager and/or SSSTS Qualified Supervisor, monitoring reports, ongoing project consultation
10-Year Insurance Backed Guarantees: price to be determined by contract value
Factors That Affect the Cost of Removing Japanese Knotweed
Removing Japanese knotweed can be a costly process, but it is essential to prevent the spread of this invasive species. The cost of removal will depend on a variety of factors, such as the size and location of the infestation, the type of control method used, and whether or not professional help is required.
In addition, local regulations may affect how much money you need to spend in order to remove Japanese knotweed from your property. By understanding these factors that influence cost, you can make an informed decision about which approach is best for your situation.
The size of the Japanese knotweed infestation is one of the main factors that will affect the cost of removal. The larger the area that needs to be treated, the more money it will take to eliminate this invasive species. If you have a small area affected by Japanese knotweed, spot treatments may be an effective solution and can help you keep costs down.
However, if the infestation is large and widespread, more intensive treatments may be necessary in order to achieve complete eradication.
The location of the Japanese knotweed will also influence removal costs. If it is growing close to a building or other structures, additional measures must be taken to protect them from damage due to the excavation process.
In addition, Japanese knotweed located close to waterways or other vulnerable ecosystems may require an additional permit and extra steps in order to protect them during removal.
The type of control method used will also play a role in the cost of removing Japanese knotweed. Spot treatments with herbicides are often more affordable than full excavations but may require multiple applications over time in order to be successful. On the other hand, removing Japanese knotweed by excavation is a more expensive option that can provide faster results.
Finally, if you need professional help with your Japanese knotweed removal project, this will add to the overall cost. Hiring an experienced contractor can help ensure that the job is done correctly and safely, which can save you money in the long run.
Japanese Knotweed treatment costs
A Japanese Knotweed Survey will determine the expense of removal. This is required so that treatment can be tailored to the amount and location of your infestation. Costs can vary greatly between different sites and the amount of knotweed on your property. Treatments may include digging up the invasive plant, spraying with herbicides or using a combination of both methods.
For small-scale infestations, manual removal can be effective and relatively inexpensive. This method involves physically removing each knotweed stem by hand, roots and all. It is important to be thorough when doing this as any remaining knotweed can grow back quickly.
For more extensive infestations, treating with herbicides may be the most effective solution. This involves applying a specialized herbicide directly to the plants using either a sprayer or root injection system. The cost of the herbicide and application equipment will need to be taken into consideration when calculating the total cost of treatment.
The estimated costs for treating a Japanese Knotweed infestation can range from £1,000 to over £10,000 depending on the size and location of the infestation. The cost may also increase if other invasive plants are present or additional work needs to be done such as removing contaminated soil. The final cost will depend on the surveyor’s assessment and recommendations.
If you are concerned about Japanese Knotweed and want to get a more accurate estimate of how much it could cost to treat your infestation, it is advisable to get a professional survey carried out by an experienced specialist.
Final thoughts
The cost of removing Japanese Knotweed can be significant, but it’s important to take action to prevent further damage and protect your property.
By understanding the factors that affect the cost of removal, you can make an informed decision about the best course of action. Whether you choose to remove Japanese Knotweed yourself or hire a professional, it’s important to act quickly to prevent its spread.
Remember, prevention is key to stopping the spread of Japanese Knotweed, so make sure to follow prevention tips to keep your property free from this destructive plant.
