Land Remediation Tax Relief

Land Remediation Tax Relief (LRTR) provides up to 150% tax relief on qualifying expenditure incurred in the cleaning up of contaminated land. Available since May 2001, it was publicised widely that LRTR was to be scrapped in March 2011 following a review by the Office of Tax Simplification. With pressure from industry representatives and their advisers, HMRC has now confirmed that LRTR will continue indefinitely.  

This fact was much less publicised, meaning some people are often wrongly under the impression that it no longer exists. 

Land Remediation Tax Relief for Japanese Knotweed

HMRC has confirmed that from April 2009 tax relief is available for the removal of Japanese Knotweed from affected sites. This is where a claimant can demonstrate that the infestation has not been planted or spread by them or another connected party.

The extension of LRTR aimed to address market failures due to long term derelict land, often involving land sites infested by Japanese Knotweed, in the hopes of encouraging the development of such land.

The nature of Japanese Knotweed means that even small fragments can lead to a significant infestation and as a result, developers are often unable or unwilling to purchase or develop land sites with such an infestation. This is due to the costs involved in removing it and the risk that it may return. In light of this, companies have found themselves unable to sell or develop their own land.

Companies that are not aware of Land Remediation Tax Relief (LRTR) could be missing out on a significant tax break. LRTR has been around since 2001, and though it is well-known in the industry, many businesses are still not aware of it. This is often due to a lack of awareness from their accountants, lawyers and surveyors.

For companies that have to deal with Japanese knotweed on their property, this lack of knowledge is even more common. Until recently, HMRC guidance did not include Japanese knotweed as a qualifying expenditure for the relief—but that has changed. HMRC now recognises that Japanese knotweed is so invasive and destructive that it satisfies the ‘harm’ test and can be claimed as qualifying expenditure for LRTR.

This means that if you are planning on removing Japanese knotweed from your land or property, you could be eligible to claim back some of the costs. For most businesses, these costs can run into thousands of pounds—meaning they could be losing out on a significant amount of money by not taking advantage of this relief.

In the case of Japanese knotweed, HMRC recognizes that land may become contaminated with the plant during ownership. In this case, LRTR is available for the cost of remediation. This is because often Japanese knotweed is introduced through means like fly tipping.

In the past, it was common for contractors to take the ‘dig and dump’ route with their Japanese knotweed disposal. Instead of eradicating the weed, they used landfill as a cheaper and faster way to get rid of it. However, we now know that this method doesn’t work in the long run; because the plant can survive even when buried, it will eventually grow back.

With landfill tax rates rising substantially, and waste removal becoming more expensive than ever, it is no longer beneficial to ignore eradiation methods in favor of landfill disposal. If you want to save money in the long run, you must approach knotweed eradication with a holistic perspective—and that includes claiming tax relief from the government.
