Your Ultimate Guide to Saving Time and Money
If you’re a homeowner, property developer, or landlord in the UK, the words Japanese Knotweed can send a chill down your spine. This invasive plant is notorious for its rapid growth and destructive root system, which can compromise property values and structural integrity. At Japanese Knotweed Plus Ltd, we understand the fear and confusion this plant brings — and we’re here to help with our Free Japanese Knotweed treatment offer, available under our unique guarantee.
Yes, you read that correctly. We offer free Japanese Knotweed treatment under specific conditions. As the only company in the UK offering a free treatment plan if our PCA-accredited surveyor misses Japanese Knotweed during a survey, we’re proud to lead the industry with honesty, integrity, and real solutions.
What Is Japanese Knotweed and Why Is It a Problem?
Japanese Knotweed (Fallopia japonica) is a highly invasive plant species that can grow up to 10 cm a day during peak season. Its underground rhizomes can extend up to 7 metres horizontally and 3 metres deep, making it incredibly difficult to remove without professional help.
Unchecked, it can:
-
Damage foundations, driveways, and drains
-
Lower property values
-
Interfere with mortgage applications
-
Spread rapidly if improperly handled
That’s why professional Japanese Knotweed removal is essential.
What Are Lenders Looking For?
If you’re buying or selling a property affected by Japanese Knotweed, you’ll likely need to meet specific lender requirements to secure a mortgage. The presence of knotweed isn’t always a dealbreaker, but it can significantly delay or complicate the process unless the right steps are taken.
Here’s what most mortgage lenders require:
-
A PCA-accredited surveyor’s report clearly identifying the extent of the infestation
-
A 5- or 10-year knotweed treatment plan backed by an insurance guarantee
-
Evidence that a professional, licensed company is managing the treatment
-
Annual progress updates and confirmation that regrowth is monitored
Without this, lenders may reduce the loan amount, request a retention, or even decline the mortgage altogether. That’s why working with a company like Japanese Knotweed Plus Ltd, which understands the full process from survey to completion, is critical.
What’s Involved in Our 5-Year Knotweed Treatment Plan?
Our 5-year treatment plan is designed to meet lender expectations while providing effective, long-term control and eradication of Japanese Knotweed. Here’s what it includes:
1. Initial Survey and Mapping
A free survey by our PCA-accredited specialists kicks off the process. We map out all visible growth and assess how far the underground rhizomes have likely spread.
2. Custom Treatment Strategy
We create a site-specific knotweed treatment plan, typically involving selective herbicide application during the growing season (May to October). In certain situations, excavation and removal may be advised.
3. Scheduled Herbicide Applications
Over the course of the 5 years, we visit your site at key growth stages to apply professional-grade herbicide treatments. This ensures we strike the plant when it’s most vulnerable.
4. Annual Monitoring
Each year, we inspect the property for regrowth and document findings in an annual report. These reports are essential for satisfying lender conditions.
5. Insurance-Backed Guarantee
The treatment plan comes with an insurance-backed guarantee, typically required by lenders and conveyancers. It ensures peace of mind even if Japanese Knotweed reappears after treatment ends.
What Makes Our Free Japanese Knotweed Treatment Offer Unique?
Many companies offer Japanese Knotweed removal services, but none offer a free treatment plan if their surveyor fails to identify the plant during a site visit.
At Japanese Knotweed Plus Ltd, we stand behind our work. If our PCA-accredited surveyor misses Japanese Knotweed on your property during a free survey, and it’s later found, we’ll treat it for free. This isn’t just a gimmick — it’s a promise based on our confidence and experience.

How Does Our Japanese Knotweed Treatment Plan Work?
Our knotweed treatment programs are tailored to each property. Depending on the location and severity, we may recommend:

Root barrier installation
