Land Remediation Relief

Your company may qualify for Land Remediation Relief (LRR) if it incurs expenditure on remediating contaminated or qualifying derelict land in the UK for the purposes of its trade or property business. For contaminated land, the contamination will normally need to result from previous industrial activity, although specific exceptions include Japanese knotweed, radon and arsenic. The company or a connected party must not generally have caused the contamination, reflecting the "polluter pays" principle. Eligibility depends on the land, its history, the nature of the contamination or dereliction and the expenditure incurred, so each project needs to be considered on its particular facts.

Land Remediation Relief can provide an additional 50% Corporation Tax deduction for qualifying remediation expenditure, on top of the normal 100% deduction where the expenditure is otherwise deductible. This means that qualifying revenue expenditure can potentially receive a total deduction of 150%.

For example, £100,000 of qualifying expenditure could potentially produce £150,000 of tax deductions. The actual benefit depends on the nature and timing of the expenditure, the company’s tax position and whether the expenditure is revenue or capital for tax purposes.

A loss-making company may, subject to the relevant conditions, surrender qualifying land-remediation losses for a payable tax credit equal to 16% of the qualifying loss surrendered. The credit is not an automatic percentage of all remediation expenditure, and detailed rules determine the amount of loss that can be surrendered.

Qualifying expenditure can include costs incurred because land is contaminated or derelict, including relevant staffing costs, materials and payments to qualifying subcontractors. Depending on the circumstances, costs associated with establishing the extent of contamination, professional fees, preparatory activity and carrying out the remediation itself can also qualify. However, the expenditure must meet the detailed conditions. Subsidised expenditure and Landfill Tax, for example, are excluded. Separating qualifying remediation costs from wider construction or development expenditure is therefore an important part of preparing a claim.

Yes. Property developers can potentially claim LRR where they acquire contaminated or qualifying derelict land and incur eligible remediation expenditure as part of the development. The treatment can differ from that of an owner-occupier or property investor because development expenditure may be held as trading stock or work in progress, affecting when the expenditure is recognised for tax purposes and when the relief is obtained. The polluter-pays and other eligibility rules still apply. For developers, identifying qualifying costs as the project progresses can be particularly valuable because separating them from wider construction expenditure retrospectively can be difficult.

Potentially, yes. A corporate landlord can claim LRR where qualifying contamination was already present when it acquired the property, subject to the other conditions being satisfied. However, a landlord cannot normally claim relief for cleaning up contamination caused by one of its tenants. For example, a landlord acquiring a previously contaminated industrial site may potentially qualify when it later remediates that historic contamination, whereas contamination arising from the activities of its own tenant can fall outside the relief.

For LRR purposes, land is broadly considered contaminated where something in, on or under it is causing relevant harm, or there is a serious possibility that it will do so. The contamination will normally need to have arisen from previous industrial activity. Relevant harm can include significant adverse effects on human or animal health and damage to buildings that materially affects their use. Specific rules also bring certain naturally occurring contaminants and Japanese knotweed within the relief. The tax definition should therefore be considered separately from simply describing a site as "brownfield" or contaminated in everyday terms.

It can. Expenditure on dealing with asbestos may qualify where the asbestos causes the land or building to meet the relevant contamination conditions and the expenditure satisfies the wider LRR rules. Qualifying costs can extend beyond the straightforward cost of removing the asbestos to certain additional costs incurred specifically because of the contamination. However, not every asbestos-related cost automatically qualifies, so it is important to distinguish remediation expenditure from ordinary demolition, refurbishment or construction costs. HMRC specifically includes additional costs of clearing asbestos within its detailed LRR guidance.

Yes, subject to the conditions. Japanese knotweed is specifically brought within the scope of LRR even though living organisms are generally excluded. However, the method used to deal with it matters. Since 1 April 2009, expenditure on removing Japanese knotweed to landfill is excluded, while qualifying in-situ treatment and treatment at off-site treatment centres can continue to qualify. Relief can also be denied where the company is treated as responsible for allowing the infestation to spread.

Potentially, yes. If qualifying expenditure was incurred but LRR was not claimed, it may be possible to amend the relevant Corporation Tax return or make a supplementary claim, provided the company is still within the applicable statutory time limit. Timing can be more complicated than simply looking at when the remediation work took place, particularly for property developers where expenditure may initially be held in work in progress and recognised later. Historic expenditure is therefore worth reviewing, but the relevant accounting periods, tax returns and claim deadlines should be checked before assuming a retrospective claim remains available.

There is no requirement to use a specialist, and your accountant may already have the necessary expertise. However, LRR claims can require a combination of tax, property, environmental and construction-cost analysis. A specialist can help determine whether the land qualifies, apply the polluter-pays rules, identify eligible remediation activity and separate qualifying expenditure from the wider development or construction costs. This can be particularly useful on larger or more complex projects where remediation expenditure is spread across contractors, professional fees and construction packages. The objective should be to identify the relief legitimately available while ensuring that the claim is appropriately evidenced and defensible.
