What is Japanese Knotweed?

Knotweed is ranked towards the top end of the World’s Most Invasive plant species and should not be underestimated on what adverse effects it can have on your property.

Japanese Knotweed spreads very fast and grows at a rapid pace throughout the summer months in the UK and can exploit all types of land and terrain and even grow through tarmac, brickwork, walls, drains, sewers, cavity walls and literally anywhere it can exploit to will do so.

Knotweed is said to affect 950,000 houses across the UK and can significantly reduce the value of your property, cost thousands of pounds to treat, can stop house sales dead in their tracks, can leave you open to litigation if it spreads from your land on to another person’s land and cost you tens of thousands of pounds.

The good news is that if it is coming from another person’s land such as railway, council land, commercial land and so on, you can typically recover all of the costs of treatment and insurance plus recover a significant cash sum to cover any devaluation of the property value.

How Can I Tell If I Have Knotweed?

You can visit our Seasonal Gallery on the below link and make yourself aware of how Kno0tweed looks throughout the seasons.

How Much Is My Property Worth with And Without Knotweed?

In the very best circumstances devaluation can be 5% of the property price, so £150,000 property value will have a minimum loss of £7,500 – plus the cost of a treatment plan and 10-year Insurance Backed Guarantee.

Where Knotweed is identified to be a fair infestation, and may be evidence of it growing in drains, sewers, close to the property or inside the property, the valuation will decrease significantly. Some severely affected properties have seen a 100% devaluation because of the extreme growth and other factors such as access to be able to treat and so on.

The Knotweed will only get worse, so you need to act fast if you think Japanese knotweed is on your land. In most cases you should be able to recover all costs and get compensation.

How Do I Remove the Weed from My Property?

A specialist treatment firm will typically attend at least once every 3 months and treat the weeds by injecting the stems of every plant again and again, and this will go on for at least 3 years, followed by a 2 year observation by the homeowner.

Once treatment starts, you should then be covered with a 10-year Insurance Backed Guarantee, so if it does come back after the 3-year treatment, your insurance will cover any additional treatments required.

What Should I Do Next?


Your survey will highlight the locations of the crowns of Knotweed and where it is coming from and spreading to; it’s direction of growth and travel, and serious issues, age, and lots more, to give you 100% expert, factual information inside an extensive written report bespoke for your property, and will include a full quote for treatment and an Insurance Backed Guarantee.
