HOMEOWNER SURVEY
If you are buying or selling a property that you suspect is affected by Japanese knotweed, it’s advisable to get a pre-purchase or pre-sale survey of the property. The survey report will tell you if knotweed is present. This is vital information if you’re buying as it will enable you to make an informed decision, and if you are selling you can have a Knotweed Management Plan (KMP) in place to give your buyer confidence to make an offer.
A Knotweed Management Plan (KMP) is a prerequisite for most mortgage lenders who will insist on proof that one is in place.

commercial survey
Japanese knotweed can cause construction to grind to a halt and cause multiple headaches for developers and landowners. The Environment Agency also states that once you find Japanese knotweed on a development site, it is essential that you put a KMP in place.
A knotweed survey done at pre-purchase or pre-planning stage is therefore vital. It will also include costs for our recommended treatment or excavation options.
