Land Remediation Tax Relief

Claim up to 28.5% tax relief for remediating unusable land.



What is Land Remediation Tax Relief?

Have you remediated otherwise unusable land? You may be able to claim tax relief of up to 28.5% of your relevant costs.

If you’re a company in the UK, you may be able to get tax relief on the costs of cleaning up contaminated land. This is called land remediation tax relief and it’s a government incentive to encourage companies to invest in the remediation of contaminated land.

To qualify for the relief, the land you’re working on must have been contaminated before you acquired it. The work you’re carrying out must be necessary to make the land suitable for its current or intended use and must be done in accordance with approved plans and procedures.

To claim the relief, you’ll need to apply to HM Revenue and Customs (HMRC) and provide details of the remediation work you’ve done, as well as evidence of the contamination and the costs you incurred. HMRC will then review your application and decide whether to grant the relief. If it is granted, you’ll be able to claim a deduction from your taxable profits for the costs of the remediation work.

Why Does the Government Offer It?

The UK has developed a reputation for excellence in land clean-up, and the clean-up work may be a component of new construction or renovations to existing properties.

With more than 400,000 hectares of contaminated soil, much of it a remnant from the Industrial Revolution, the UK has made the clean-up of this area a top priority, spurred by economic motivations, top-notch legislation, and a goal to restore the entire business environment.


Does my development fulfil the requirements for land remediation?

Housebuilders, real estate developers, real estate speculators, and owner occupiers are some businesses that stand to gain from LRR.

The following conditions must be met to qualify for land Remediation Tax Relief: 

  • The land must be in the UK.
  • The company must purchase the land (or a minimum 7-year lease of it) for its commerce or real estate rental business.
  • At the time of acquisition, the entire or a portion of the land was contaminated
  • There is a three-year time limit on retroactive applications for relief from land remediation.
  • The price of the site wasn’t reduced directly to allow the buyer to carry out decontamination works


What expenses are eligible for Land Remediation Relief?

The following conditions must be met to qualify for land remediation relief:

  • The clean-up of polluted terrain
  • Removing asbestos from structures
  • Exposing hidden or buried structures.
  • The remediation of harmful microorganisms and naturally occurring pollutants including radon, arsenic, and Japanese knotweed
  • Soil and land testing at the start and end of the process


What isn’t eligible for land remediation?

There are some exceptions to the benefit, including:

  • If the claimed company was responsible for the contamination.
  • Decontamination costs are reduced, for instance, through grant financing.
  • Due to the contamination, the land’s purchasing cost was reduced.
  • The claiming business lacks a “major interest” (freehold or a minimum lease of 7 years).
  • Retrospective claims have a three-year time limit.


What is “contaminated land”?

Contaminated land refers to land that has something on, in, or under it that causes “relevant harm” or has a high likelihood of causing such harm. If the contamination is caused by industrial processes, it is not considered a natural source such as arsenic, radon, or Japanese knotweed.


What is “derelict land”?

Land or buildings that have contamination due to industrial activity that may lead to “relevant injury” are known as derelict land.

Several decontamination methods used for both land and buildings qualify for tax exemption, including removing contaminated soil and water, treating harmful organisms, getting rid of buried structures and invasive plants, and eliminating natural toxins like radon and arsenic. Relief also includes removing asbestos from structures, post-tensioned concrete, foundations of buildings and machines, underground redundant services, and reinforced concrete basements.


What are the benefits of land remediation relief?

Developers can claim a 50% enhancement instead of a 150% enhancement if they consider their expenses as revenue expenditure that is already deductible for tax purposes. Many decontamination methods on both land and buildings qualify for tax exemption.

With the current Corporation Tax rate of 19%, the 150% tax cut results in a 28.5% tax savings gain (28.5p for every £1 invested), while the 50% boost tax cut results in a tax savings gain of 9.5% (9.5p for every £1 invested).

Companies experiencing a loss can choose to surrender the opportunity to use the losses against future profits and instead gain immediate cash and tax credit from HMRC, equivalent to 24% of the total spent on qualifying decontamination activities.

What our clients have to say

It was a pleasure working with the guys at Bonham & Brook, especially considering that, with the wealth of knowledge backed up with the expertise of an ex HMRC officer, we had confidence going ahead with a claim for the first time. After successfully receiving a substantial refund, we would not hesitate doing another claim and, it goes without saying, Bonham & Brook will be our preferred partners going forward. Thank you, again.

Chris Strik

Managing Director

We worked with the team at Bonham & Brook on the R&D claim that we were unaware of. To our surprise they made the whole process seamless and we received our refund from HMRC. We will definitely be using B&B again for our R&D claim to help us grow our business.

At first I believed that R&D tax credits were a little too good to be true or that my company would not be applicable. Jenson, Hannad and the team's expertise and experience reassured and guided me through the process. I had to put in approx. 1 - 2 hours work and they did the rest of the application. The first time we worked together they were able to claim for the previous 2 years, so we received a bumper double rebate. This money has helped us grow the business by having the cash to grow the team and increase our marketing budget. My business has grown thanks to their work, so I am eternally grateful.
