What is Japanese knotweed?

Japanese knotweed is a tall, fast-growing Japanese plant. It has bamboo-like stems and can grow white flowers, the leaves of the Japanese knotweed, when mature, are green and flattened at the base.

Why do mortgage lenders have a problem with Japanese knotweed?

As it grows so quickly and can spread rapidly, knotweed can overtake a garden and soon cause damage to the property. It can cause issues such as the roots blocking drains and even damaging foundations if left untreated.

Such damage can seriously affect the value of the property, which is why some mortgage lenders are more restrictive with Japanese knotweed mortgages.

Getting a mortgage with Japanese knotweed

Every lender will require a professional mortgage survey to assess the knotweed and property in general, and they will judge the extent to which the knotweed causes (or will cause) a risk to the property.

Then they will determine suitability based on their own policy for Japanese knotweed mortgages. This is where which lender you approach matters, because some mortgage lenders are much more flexible than others.

To find the best options available to you today make an enquiry and talk to one of the brokers we work with who are experts when it comes to knowing which lenders are most flexible when it comes to Japanese knotweed mortgages.

How lenders assess the risk Japanese knotweed may pose

All lenders are different and will view the Japanese knotweed on its risk categories, there are generally four categories:

  1. Japanese knotweed is not on the property but can be seen on a neighbouring property, which is more than 7 metres away from the boundary.
  2. Japanese knotweed is seen on a neighbouring property, but is within 7 metres of the boundary.
  3. Japanese knotweed is present in the boundaries of the property, but is still more than 7 metres from a habitable space (you may need to have further investigations completed by a qualified or experienced person).
  4. Japanese knotweed is within 7 metres of the habitable space and/or causing serious damage to outbuildings, drains, paths and boundary walls. (With this fourth category, a further investigation would be required by an appropriately qualified and or experienced person.) 

How can I get a mortgage with Japanese knotweed?

Many borrowers have issues obtaining a mortgage because the risk category of the Japanese knotweed doesn’t fit the lender they have approached.

Here are some of the risks and how they may affect your mortgage application.

Risk Category

Description

Chances of Mortgage Approval

1

Japanese knotweed is not on the property but can be seen on a neighbouring property, which is more than 7 metres away from the boundary.

More likely to be approved at higher Loan to Value (LTV) as deemed lower risk. Concern from some lenders, but still quite possible.

2

Japanese knotweed is seen on a neighbouring property, but is within 7 metres of the boundary.

Possible but some lenders will need it to be specifically reported in the valuation. Generally no further action required.

3

Japanese knotweed is present in the boundaries of the property, but is still more than 7 metres from a habitable space (you may need to have further investigations completed by a qualified or experienced person).

Possible but likely to require a specialist survey before lending is formally approved.

4

Japanese knotweed is within 7 metres of the habitable space and/or causing serious damage to outbuildings, drains, paths and boundary walls (With this fourth category, a further investigation would be required by an appropriately qualified and or experienced person).

Possible but likely for repair work to be carried out before approval. Perhaps condition of mortgage offer is added for work to be completed, or even a retention held by the lender at the point of the mortgage completion, to be released once repair work is signed off.

Japanese knotweed mortgage lenders

As mentioned, many lenders will decline an application where the property has knotweed on or near the boundary. 

The good news is that there are some lenders who have a completely different policy to those who are more specialist and approve Japanese knotweed mortgages regularly. The brokers we work with know who they are, call 0808 189 2301 for a free, no obligation chat.

How to remove Japanese knotweed if you can’t get a mortgage

If Japanese knotweed is stopping your mortgage application from going through, one possible solution is to remove the knotweed using specialists who carefully ensure its total removal and destruction (more expensive), or (cheaper) run an ongoing treatment plan over 5 or so years.

The costs to remove it can vary depending on how much there is in the area you’re looking to remove it from. There may also be requirements from the lender that the provider of the service offers a Japanese knotweed guarantee for the mortgage to be approved.

Is there help to deal with Japanese knotweed available?

The Property Care Association (PCA) has looked at whether mortgage lending decisions relating to the presence of Japanese knotweed are currently based on sound scientific evidence of its effects on the built environment, and what guidance for the sector currently exists.

Since the PCA formed the Invasive Weed Control Group in 2012, they have maintained the position that the plant is not a destroyer of buildings, and that it should just be regarded as any other type of property issue.

Members of the Invasive Weed Control section of the PCA are qualified and regulated in Japanese Knotweed management and are said to deliver efficient, effective and reliable treatment.

The (PCA) has created its Invasive Weed Control Document Library. This includes guidance notes, information leaflets and a Code of Practice - all available for free download - to help people affected by Japanese knotweed.

This information can be downloaded here and there is also a short PCA video guide to dealing with Japanese Knotweed.

If you’re still unsure, have a chat with one of the brokers we work with on 0808 189 2301. We’ll match you with a broker who is expert when it comes to securing mortgages for properties with Japanese knotweed and can give you the right advice.

Is it possible to get a Japanese knotweed mortgage on a buy to let property?

Typically, the surveyor's report will echo the residential lending policy if applying for a buy-to-let (BTL) mortgage on a property with Japanese knotweed.

Normal rules for BTL lending will apply in terms of increased (usually) deposit and a different measure of affordability based on the rental income of the property. You’ll find more information in our guide to buy-to-let mortgages.

Can I get a mortgage on a commercial property with Japanese knotweed?

This can vary from lender to lender but, yes, there are lenders that would consider commercial mortgages on properties with Japanese knotweed.

Since every lender deals with the problem of Japanese knotweed differently, whether or not you can get a commercial mortgage for the property in question will depend on the extent of the Japanese knotweed issue and the lender you approach. 

Lenders assess Japanese knotweed on a case-by-case basis and the specialists we work with would be able to establish which lenders would be the best to approach and help you understand all the options which may be available to you.

Commercial mortgage lenders can be a little more restrictive and the use for the property can also have an impact on the lending decision.
