Impact assessment meaning

Published by a LexisNexis EU Law expert
What does Impact assessment mean?
In practice, an impact assessment is an evidence-based appraisal of the likely legal, economic, social and environmental effects of a proposed law, policy or project, used to inform decision-making and scrutiny. The term is descriptive and used across contexts; some forms are defined in legislation (for example, Environmental Impact Assessment under planning law and Data Protection Impact Assessment under the UK GDPR/EU GDPR), while others derive from policy guidance. In the EU legislative process, the European Commission prepares an impact assessment for initiatives expected to have significant economic, social or environmental effects, before proposing legislation. It analyses the problem, EU added value (subsidiarity/proportionality), policy options and their costs/benefits, distributional effects and fundamental rights, and is summarised in an Impact Assessment Report describing who is affected, the environmental, social and economic impacts, and the consultation strategy and results. Where impacts are not expected to be significant, the Commission publishes a shorter roadmap/inception impact assessment (now issued as a “call for evidence”) rather than a full assessment. See also Roadmap. Comparable practices exist in the UK and Ireland: regulatory impact assessments (RIA/IA) accompany many Bills and statutory instruments (with UK IAs scrutinised by the Regulatory Policy Committee), and public bodies commonly undertake equality impact...

HMRC support and objections in UK Part 26 schemes and Part 26A restructuring plans: practitioner checklist, required information, assessment criteria, and key case law

HMRC guidance on compromises using Part 26 schemes and Part 26A restructuring plans In corporate insolvencies, HMRC commonly ranks as a secondary preferential and/or unsecured creditor (see Practice Note: Waterfall of payments—a comparative guide), a status that often serves as the relevant comparator or alternative to a Part 26 scheme or a Part 26A restructuring plan. On 1 November 2023, HMRC issued guidance covering compromises under Part 26 schemes (see: Schemes of arrangement—overview) and Part 26A restructuring plans (see: Restructuring plan—overview) (see: HMRC publishes guidance on using debt management schemes to restructure finances—LNB News 15/11/2023 13). Practitioners should take account of this guidance whenever a proposed scheme/plan includes HMRC as a creditor. HMRC will only back a restructuring where it considers there is a realistic prospect of success. If HMRC does not consider success realistic, it will engage with the scheme/plan proponent to explore other means of repaying HMRC’s debt, which may involve a formal insolvency process. The debtor must have submitted all outstanding...

How to apply to lift the administration moratorium: England and Wales checklist (administrator consent, court application, service and directions hearing)

The moratorium in administration Central to administration, the moratorium operates as the principal device that enables a company rescue, a restructuring, or the disposal of the business. Its objective is to afford the company and its administrator a period of breathing space to shape and carry out proposals, and to scrutinise the position of the company, its business and its assets. That pause creates room for careful assessment and orderly planning. The consequence of the moratorium (and any interim moratorium) is that proceedings, enforcement and other steps cannot be taken against the company or its property while it remains in force. Claims or actions may only be commenced or continued with the administrator’s consent or the court’s permission. For further detail on the moratorium and its impact, refer to Practice Note: The moratorium in administration. The process of applying to lift the moratorium Before issuing any application requesting the court’s permission to lift the stay, the applicant should first seek the administrator’s agreement. The administrator may consent,...

Rights of light in development: due diligence, impact assessment and injunction risk mitigation—checklist (England and Wales)

This checklist outlines the steps a developer should follow when conducting due diligence on rights of light, and the approaches a developer can take to reduce the risk of an injunction being secured. A right of light is an easement that permits a property owner to receive natural light through an opening in a building on their land. The owner of land encumbered by a right of light must not impede it without permission. Accordingly, for any intended development it is vital to establish: whether any nearby building benefits from a right of light—see Practice Note: Establishing and maintaining rights of light the effect of the planned works on those rights of light—see Practice Note: Rights of light claims the remedies available to the holder of the right of light—see Practice Note: Rights of light claims A plan must be devised to manage any such rights, in collaboration with a specialist rights of light surveyor.

High Court quashes Norfolk Vanguard development consent for failure to assess cumulative impacts with Norfolk Boreas under EIA Regulations 2009: unlawful deferral and inadequate reasons (England and Wales)

Pearce v Secretary of State for Business, Energy and Industrial Strategy [2021] EWHC 326 (Admin) What are the practical implications of this case? While the facts are specific to this matter, multiple offshore schemes along England’s east coast are moving through consent, and each must robustly account for cumulative effects. The case also underlines mounting pushback from local communities against sizeable onshore infrastructure in the area, coinciding with BEIS’s programme reviewing offshore transmission and different approaches to linking offshore wind schemes and landing renewable power. The court further made clear that, even where a proposal aligns with government policy and helps deliver low‑carbon, renewable generation consistent with legal duties towards ‘net zero’ and tackling climate change, that alignment does not displace the requirement for any application to evaluate every impact properly and in accordance with the law. All such proposals therefore need to demonstrate, through the application process, that cumulative and project‑specific effects have been considered with sufficient rigour, rather than assuming policy support or climate objectives will...

National policy 25-Year Environment Plan —the 25-Year Environment Plan outlines the government’s commitments to enhance the environment within a generation. The Environmental Improvement Plan 2023 (EIP 2023) for England was the first statutory update to the 25-Year Environment Plan under the Environment Act 2021 (EA 2021). On 1 December 2025, it was replaced by the Environmental Improvement Plan 2025 (EIP 2025), now the current environmental improvement plan for EA 2021 purposes. EIP 2025 renews the long-term framework for achieving environmental outcomes, revises the interim targets in EIP 2023 and adds two new interim targets. EIP 2025 is pertinent to waste planning as part of the broader policy to improve resource efficiency and drive the move to a more circular economy, complementing the Resources and Waste Strategy and the Waste Management Plan for England (see below).

Breach of planning control and enforcement action Under the Town and Country Planning Act 1990 (TCPA 1990), any breach of planning control can be met with enforcement measures. For these purposes, a breach of planning control is understood to mean: undertaking development without the requisite planning permission — this presumes that an unauthorised operation or a material change of use has occurred which amounts to development within TCPA 1990, s 55, that such development requires planning permission, and that no permission has been secured When determining whether a breach of planning control has arisen in this context, the applicable guidance and case law on the meaning of ‘development’ must be applied; see Overview: Is planning permission required?...

NSIP DCO examination procedure: fast-track, written representations, hearings, changes, local impact reports, statements of common ground, and decision-making under the Planning Act 2008 (including forthcoming 2025 amendments)

The Planning Act 2008 (PA 2008) establishes the consent framework for nationally significant infrastructure projects (NSIPs) across energy, transport, water, waste water and waste. Decisions on development consent order (DCO) applications may be taken by reference to any relevant National Policy Statements (NPSs), which articulate national policy for NSIPs. See Practice Note: National Policy Statements. While the Secretary of State (SoS) is legally accountable for the decision, in practice the government entrusts acceptance and examination of applications to the Planning Inspectorate (PINS). See Practice Note: Examination of nationally significant infrastructure projects—general. The government has issued a ‘Collection: National Infrastructure Planning Guidance Portal’, containing guidance on NSIP pre-examination, the examination itself, the fast-track route for NSIPs, and awards of costs relating to the examination of DCO applications. Collectively, these provisions define the route by which nationally significant schemes are assessed and authorised, with guidance set out in practice notes and the collection. Fast-track process Under PA 2008, s 98(1), the Examining Authority (EA) must conclude examination of the application...
