What Is Land Remediation Relief?
Land Remediation Relief (LRR) is a corporation tax relief that allows Northern Ireland companies to claim a 150% deduction for expenditure on remediating contaminated land. For every 100 spent on qualifying remediation work, the company can deduct 150 from its taxable profits — an additional 50% deduction on top of the normal 100% deduction.
LRR was introduced in 2001 (with subsequent amendments) to incentivise the clean-up of contaminated sites. It applies to both land and buildings, and crucially for building owners, asbestos can be a qualifying contaminant under the relief. This means that the cost of dealing with asbestos in commercial and industrial buildings — including encapsulation — can attract the enhanced 150% deduction.
Despite being available for more than two decades, LRR remains one of the most underused tax reliefs open to Northern Ireland companies. Many building owners and their advisers are unaware that asbestos qualifies, or assume that only land contamination (soil, groundwater) is eligible. This guide explains how LRR applies to asbestos in buildings and how to claim it.
Who Qualifies for LRR?
To claim LRR, the following conditions must be met:
1. The claimant must be a Northern Ireland company paying corporation tax. LRR is a corporation tax relief, so it is available to limited companies and other corporate entities. Sole traders and partnerships cannot claim LRR (though they may claim the normal deduction for remediation costs), and companies taxed in the Republic of Ireland cannot claim it at all.
2. The land or building must be contaminated. The contamination must be such that it constitutes a risk of harm to human health or the environment. Asbestos-containing materials in buildings clearly meet this threshold — they present a known health risk (mesothelioma, asbestosis, lung cancer) and are classified as hazardous waste when disturbed.
3. The contamination must not have been caused by the claimant. This condition is designed to prevent companies from contaminating land and then claiming tax relief for cleaning it up. For asbestos in buildings, this is almost always satisfied because the asbestos was installed decades ago by a previous owner or builder — the current owner inherited the contamination.
4. The expenditure must be on remediation. The work must address the contamination — removing it, treating it, or containing it (encapsulation). The cost of the remediation work itself qualifies, including professional fees, materials, and contractor costs directly related to dealing with the asbestos.
Asbestos as Qualifying Contamination
The rules of the relief treat asbestos in buildings as contamination that can qualify for LRR, where it is causing or could cause harm to human health. Asbestos-containing materials that are deteriorating, at risk of disturbance, or in occupied spaces are the typical examples.
Both asbestos removal and asbestos encapsulation qualify as remediation expenditure. Encapsulation is treated as "containment" of the contaminant — a recognised remediation technique. There is no requirement to remove asbestos to claim the relief; encapsulation is equally valid.
The most common qualifying scenarios for LRR asbestos claims include: asbestos cement roofing and wall cladding on warehouses and industrial units, asbestos insulating board (AIB) in commercial buildings, asbestos lagging on pipework and boilers, and asbestos floor tiles in commercial premises. All of these can be addressed through encapsulation, removal, or a combination of both.

How the 150% Deduction Works
The mechanics of LRR are straightforward. Instead of deducting the actual cost of remediation (100%) from taxable profits, the company deducts 150%. The additional 50% is the "enhanced deduction" — effectively a government subsidy for dealing with contamination.
At a corporation tax rate of 25%, the tax saving from the enhanced portion is: 50% (additional deduction) x 25% (tax rate) = 12.5% of the qualifying expenditure. Added to the normal tax relief of 25%, the total tax benefit is 37.5% of the qualifying expenditure.
For companies in a tax loss position, there is an additional option: instead of carrying forward the enhanced deduction as part of a loss, the company can surrender the qualifying loss for a payable tax credit — worth around 24 for every 100 of qualifying spend. This means loss-making companies can receive a cash payment rather than waiting for future profits to use the relief. Your accountant will confirm the current position.
Worked Examples
Example 1: Profitable Warehouse Owner
A logistics company in Northern Ireland owns a 3,000m² warehouse with an asbestos cement roof. It commissions Duratite to encapsulate the roof using Nexseal LE interior spray foam. The company is profitable and pays corporation tax at 25%. The figures below are shown per 100 of qualifying spend, so they scale to any project size.
| Item | Per 100 of Spend |
|---|---|
| Encapsulation cost | 100 |
| LRR deduction (150%) | 150 |
| Normal deduction (100%) | 100 |
| Enhanced portion | 50 |
| Tax saving on enhanced portion (25%) | 12.5 |
| Tax saving on normal portion (25%) | 25 |
| Total tax saving | 37.5 |
| Net cost after tax relief | 62.5 |
Example 2: Agricultural Building Conversion
A property development company in Northern Ireland acquires a farm with asbestos cement barns. Before converting the barns to offices, it encapsulates the asbestos cement. The project also includes thermal insulation (Nexseal LE), which provides both encapsulation and insulation, and 75% of the cost is attributed to asbestos remediation. Again, the figures are per 100 of spend.
| Item | Per 100 of Spend |
|---|---|
| Total encapsulation/insulation cost | 100 |
| Proportion attributable to asbestos remediation | 75 (75%) |
| LRR deduction on qualifying portion (150%) | 112.5 |
| Normal deduction on remaining portion (100%) | 25 |
| Total deduction | 137.5 |
| Tax saving at 25% | 34.4 |
| Net cost after tax relief | 65.6 |
Note: Where encapsulation expenditure serves dual purposes (asbestos remediation and thermal insulation), the tax adviser will typically apportion the cost between the remediation element (qualifying for 150%) and the insulation element (qualifying for normal 100%). The apportionment must be reasonable and supportable. Duratite provides detailed specifications that help your accountant identify the remediation proportion.
What Expenditure Qualifies?
The following costs typically qualify for LRR when dealing with asbestos in buildings:
Qualifying expenditure: Asbestos survey and sampling, encapsulation materials and application, specialist removal costs, scaffolding and access directly related to the asbestos works, air monitoring, waste disposal, post-remediation testing, and professional fees for managing the remediation (project management, health and safety consultancy).
Expenditure that does NOT qualify: General building repairs unrelated to asbestos, new roofing that replaces removed asbestos cement (this is capital expenditure, not remediation), cosmetic improvements, and professional fees not directly related to the asbestos work (such as general architectural fees for a wider building project).
How to Claim LRR
Claiming LRR is done through the company's corporation tax return. The process is:
1. Commission the remediation work. Engage a competent contractor (such as Duratite) to carry out the asbestos encapsulation or removal. Ensure you receive detailed invoices that clearly identify the remediation work and costs.
2. Obtain supporting documentation. Duratite provides a comprehensive technical report with every encapsulation project, including: pre-works asbestos survey confirming the presence of ACM, the encapsulation specification and methodology, confirmation that the work constitutes remediation of contaminated land, and post-works compliance documentation.
3. Instruct your accountant. Provide the technical documentation and invoices to your accountant or tax adviser. They will include the LRR claim in the company's corporation tax return, claiming the 150% deduction on qualifying expenditure.
4. Retain records. The tax authority may enquire into LRR claims. Keep all documentation — asbestos surveys, specifications, invoices, contractor certifications, and completion certificates — for at least 6 years.
