Yes, if the knotweed is not being treated by a specialist company. However with the right treatment and insurance backed guarantee most banks and buildings societies will lend.

Mortgage lenders including the building societies and high street banks refuse to lend money in the form of a mortgage where their surveyor identifies the presence of Japanese knotweed on the property. Refusal has also resulted where no Japanese knotweed is present on the site, but is on adjoining land. Surveyors employed by the banks are instructed to look out for Japanese knotweed.

Banks refuse mortgages because the plant can cause significant property damage, and can devalue the property due to the risk level this poses. This affects the loan to value ratio and reduces the value of the security held by the bank. Lending money on a property with untreated knotweed is just a risk the banks are not willing to take.

The good news is that we do have several residential solutions with an Insurance Backed Guarantee (IBG) underwritten by Syndicate 4444 (Canopius) at Lloyd's that satisfies most lenders. Our Japanese knotweed removal methods range from herbicide treatment programmes using foliar spray, or in some cases stem injection, to physical removal methods such as Resi-Dig-Out™. For much larger areas our commercial Xtract™ or Dig & Dump solutions may be appropriate. Our work is offered with an insurance backed guarantee, which provides security for the lenders and yourself as the homeowner. If regrowth is experienced during the time of the guarantee, we will treat this at no extra cost.

If you are a buyer or seller with hugely different perceptions of the scale of the knotweed problem and can't agree on apportionment of costs, you may find our Survey and Japanese Knotweed Management Plans of use. These can be commissioned by buyer, seller or jointly, to ensure a completely impartial view is given by a professional firm. Once this report is completed, we would be able to undertake the removal work at a fixed cost, and provide a guarantee that can be assigned to the new owner upon completion of the sale.
