Government Response to Land Remediation Tax Relief Consultation

Land Remediation Tax Relief (LRTR) is a long-standing UK Corporation Tax incentive designed to encourage the redevelopment of contaminated or long-term derelict land.  It offers tax deductions at up to 150% of qualifying remediation costs, along with a payable tax credit for loss-making companies.  The policy intention historically was to support brownfield regeneration and help reduce reliance on greenfield development.

On 23 June 2026, HM Treasury published its ‘Summary of Reponses’ to the consultation launched in July 2025 (that closed in September 2025), which sought to review the effectiveness of LRTR and assess whether it continues to achieve its objective of encouraging brownfield land development.

Although remaining relevant in principle, the review found LRTR is not consistently delivering its intended impact at scale.  Evidence from the consultation responses and industry engagement highlighted that LRTR is rarely a decisive factor in development decisions.  Instead, site selection continues to be driven by market conditions, planning considerations, and build costs, with the tax relief often treated as a secondary or retrospective benefit.

The consultation highlights several practical limitations that reduce the effectiveness of the current LRTR tax relief.  The recurring theme throughout the responses is the complexity of the tax rules, as shown in the key themes below.

Timing and uncertainty are central concerns.  Developers frequently struggle to estimate qualifying remediation costs early in a project lifecycle, particularly before detailed site investigations have been completed, and costs are yet to be tendered.  Meaning the benefit of LRTR is realised later than is commercially useful for incentivising upfront decisions and is often excluded from initial viability assessments.  This potentially undermines its policy intention and reduces its influence on investment decisions.

Eligibility criteria were repeatedly referenced.  Particularly rules such as the requirement for land to have been continuously derelict since April 1998, or restrictions linked to responsibility for contamination or connections to former polluters are widely viewed as outdated and restrictive.  Our own managing director, Alun Oliver FRICS, has been part of government lobbying to amend the unduly restrictive nature of the dereliction rules, that have only been becoming more onerous since being introduced in 2009, where the April 1998 date has been fixed, despite mechanisms within the legislation to permit periodic updates.

Operational challenges further limit accessibility.  In practice, remediation works are often procured within wider construction contracts, making it difficult to isolate qualifying expenditure.  This necessitates detailed cost analysis, increasing administrative burden, which can be prohibitive for smaller developers with less technical in-house expertise.  The interaction with other tax rules, including capital allowances, adds an additional layer of complexity.

Evidential requirements and record-keeping.  Successful claims depend on robust documentation - such as environmental reports, contractor cost breakdowns, and detailed apportionments - which may not be readily available unless captured throughout the project.  Especially if the claimant is unaware of the available reliefs before commencement of the project.  This raises compliance risks and can discourage some businesses from claiming at all. 

Despite these issues, LRTR remains a valuable tax relief, particularly for highly contaminated or marginal sites.  Stakeholders broadly agreed that reform should focus on improving accessibility and ensuring the relief better supports early-stage decision-making.

While no specific legislative changes have yet been announced, the government has confirmed that it has “identified limitations in the current regime” and “sees a compelling case for reforming” LRTR.

It has been widely accepted by industry that LRTR needs improving – potentially through simplifying the regime, improving clarity around eligibility, and enabling earlier access to benefits.

There are many potential reforms, which could include streamlining technical rules, reducing administrative burdens, and enhancing the ability for developers to factor LRTR into project viability from the outset.   However, frustratingly, the government is not at this time committing to any specific outcomes and is still relying on finding “cost-effective” solutions – a term that might see reform kicked further down the line, rather than truly incentivising brownfield redevelopment.

In the meantime, businesses should take a proactive approach.  This includes considering LRTR early in project planning, structuring contracts to clearly identify remediation works, and maintaining detailed, contemporaneous records to support any appropriate tax claims.

Despite the complexity and issues raised, E³ Consulting has undertaken a great many LRTR claims since this fiscal incentive was first introduced in 2001 (later modified in Corporation Tax Act 2009) - either in isolation (standalone LTRT claim), or as part of a wider project analysis - including capital allowances and/or Repairs & maintenance.  We can help you identify the potential tax savings and offer a cost effective, often contingent fee, to ensure a clear and transparent link between our fees and your tax savings.
