We can help you

Identify and remove japanese knotweed

As experts in Japanese Knotweed, we take great pride in providing a professional, reliable and friendly service to home owners, managing agents, landlords, local authorities and housing associations.

Unsure if you have Japanese Knotweed? Simply send a photograph of the suspected plant to us and we will confirm its identity for you. It is helpful for us if you provide a general photo of the plant and two detailed ones –  in particular a photo of the leaves and a photo of the base of the stems. We provide this service for free.

You can also try our 3-Step Identification Process (below) and let us know.

What does Japanese Knotweed look like?

Our 3-step process to identifying Japanese Knotweed


The leaves are NOT heart shaped at the top but flat, at the tip they are heart shaped.  The leaves look more like a small gardening spade shape, pointy at the end but flat at the top.

The stem where the leaves come off is zig-zag in shape.

survey & quote


If you are based in Bromley, West Wickham, Croydon, South London, depending on the information you provide, we can visit and carry out a free survey and no obligation quote to treat and control your Japanese Knotweed.


If you are located further afield in the South East of England and are looking to control your Japanese Knotweed, please do contact us to see if we can cover your area.

Alternatively we can often provide a quote from the photographic information you have provided of the plant and the area where it is sited. This can be helpful if you are managing sites and are not based where the Japanese Knotweed is located.

If you require a written Japanese Knotweed identification report following a survey for mortgage purposes, this can be provided at an additional cost.

treatment plans

treatment plans & pricing

Our treatment plans for Japanese Knotweed are tailored around your needs.


Typically, if you contact us in April and require a five year management plan as you are intending to sell your property, we will visit 2-3 times in the first year and thereafter at least twice a year to ensure complete control, removal and eradication of the Japanese Knotweed.


The treatment plan is on the property and is automatically transferred to the new owners once you have provided us with their details.

To assist in selling your property and meeting the needs of the potential purchaser’s mortgage company we offer five or ten year management plans, as well as Insurance Backed Guarantees (IBGs) for that period of time.

We use a mixture of stem injection, spraying and weed wiping depending upon the infestation to ensure your Japanese Knotweed is swiftly controlled.

The cost to hire us to treat, remove and eradicate Japanese Knotweed in London and the South East increases depending on the area requiring treatment.

Our prices start from £100.

Simple, one-off treatment (for home owners who are not intending to sell but have simply identified a small amount of Japanese Knotweed which they wish to remove before it becomes established):

From £100


Five-year management plan for a small area:

£1,500 – £2,000 +VAT​

If you are intending to sell your property and require an Insurance Backed Guarantee (IBG) then payment is to be upfront. This means we will continue to treat the Japanese Knotweed once you have sold the property (assuming the new owners give us permission).​

For general five year management plans, payments are due at the start of each year on an annual basis.
