Japanese Knotweed Insurance Backed Guarantee

All work undertaken by TP Knotweed includes a 10-Year Insurance Backed Guarantee in line with industry standards (with the exception of Horsetail). This provides our clients with the confidence that works have been carried out by an accredited specialist Japanese Knotweed contractor and should any invasive plant re-growth occur following remediation, it is covered by our robust guarantee.

When is the Knotweed guarantee issued?

For excavation contracts, the 10-Year Insurance Backed Guarantee is issued as soon as the initial excavation works have begun on site. We then conduct bi-annual monitoring visits at the site for 2 years (2 growing seasons), under the guarantee to ensure that there has been no invasive plant re-growth.

For 5-year herbicide treatment programmes, the 10-Year Insurance Backed Guarantee is registered and active from day one.

Why do I need a guarantee?

If you are looking to buy or sell property and land affected by Japanese Knotweed, it is a mandatory requirement by all mortgage providers that a 10-year insurance backed guarantee is in place. The guarantee is also in place to give you peace of mind that should any re-growth occur during the guarantee period, it will be treated free of charge. It also provides cover in the highly unlikely event that TP Knotweed Solutions ceased to trade.

What is covered by the Insurance Backed Guarantee?

The 10-year insurance backed guarantee covers any re-growth at the subject property or site, within the guarantee period. Should you notice any re-growth, simply contact TP Knotweed and we will re-attend to treat any plants using herbicides, at no additional cost. This insurance also allows for another accredited contractor to carry out these works, should TP Knotweed cease to trade.

What isn’t covered?

Our guarantee does not cover damage to buildings, properties, hard surfaces, drainage, loss of value or other personal property including but not limited to: non-target plants within a garden/ site, other structures or buildings within the subject property grounds, or any of the above within neighbouring properties. It does not cover spread to or from a neighbouring garden, if it has not been included within our remedia on programme. Full terms and conditions can be provided upon request.

How much will it cost?

For a standard 10-year insurance backed guarantee, the cost is £131.00 per affected property, for contracts up to £5000. For excavation works and contracts in excess of £5000, the 10-Year Insurance Backed Guarantee fee will be charged, based on a percentage of the contract value.

What happens to my guarantee if I move house or sell my development site?

The guarantees are assigned to the site or property and not to the owner, which enables them to be fully transferable. We simply ask that any new owners details are provided, so that our system and the IBG documents can be updated.
