At SE Knotweed, a management plan is the written schedule of how a knotweed stand will be treated, monitored and guaranteed, naming the method, the number of visits, the monitoring period and the guarantee term.
At SE Knotweed, a Japanese knotweed management plan is the written schedule of how a stand will be treated, monitored and guaranteed, produced from the survey findings and naming the method, the number of visits, the monitoring period and the guarantee term.
It is the working document that turns a survey finding into an agreed course of action, and it is what a solicitor and a mortgage valuer read to see the knotweed is being dealt with. We issue one with every survey where treatment is advised.
A management plan includes the confirmed species, a measured plan of the stand and the 3 metre zone, the RICS management category, the chosen treatment method, the visit schedule across the growing seasons, the monitoring period and the insurance-backed guarantee term.
It also records the waste route where soil is removed, the method statement the operatives follow and the site-specific risks. Everything a lender, solicitor or the next owner needs sits in one document.
Lenders and solicitors want a management plan because it converts an open-ended risk into a defined, costed and guaranteed programme, which is what allows a valuer to lend and a conveyancer to answer the buyer's enquiries.
Without a plan, a stand of knotweed is an unpriced liability. With one, plus an insurance-backed guarantee, the future cost is fixed and underwritten, so the transaction can proceed even though treatment continues afterwards.
A management plan runs for the length of the treatment and the monitoring that follows it, commonly 3 to 5 growing seasons for a herbicide programme, with an insurance-backed guarantee term that often extends to 10 years so a lender is covered well beyond the active treatment.
Excavation clears a stand in days, so its plan is shorter, but the guarantee term is what a lender looks at. We confirm the exact periods with your plan.
A survey confirms and measures the problem, while a management plan sets out the solution: the survey records the species, the stand and the RICS category, and the plan names the method, the visits, the monitoring and the guarantee that will deal with it.
The two arrive together in practice, because we write the plan from what the survey finds on site. One diagnoses, the other treats.
A management plan carried out by an audited specialist comes with an insurance-backed guarantee, which commits to returning and re-treating at no further cost if regrowth appears within the term. The guarantee is the part a mortgage lender relies on.
We set the term out in the plan, and the guarantee page explains how the cover works and what it does and does not include.
The management plan is produced within the £150 to £500 survey fee, so the cost that matters is the treatment the plan schedules, from around £1,200 for a herbicide programme to £12,000 for full excavation.
We give a fixed treatment figure with the plan once the stand is measured, and the cost pillar breaks it down by method and size.
A management plan and its insurance-backed guarantee can usually be assigned to a buyer, which is exactly why they unblock a sale: the incoming owner inherits the cover, so their lender lends against a property with the risk already underwritten.
We prepare the paperwork so the plan and guarantee pass cleanly on completion. Tell us a sale is in progress and we will make sure the documents are assignable.
Tell us the address and what a surveyor flagged. We confirm the plant, record the RICS category and set out the figures.
