If your development could significantly affect land, wildlife, water, or landscapes, the council will expect formal ecological evidence in London before it can be approved. Environmental Impact Assessments (EIA) in London span to major housing, infrastructure, commercial and mixed-use developments.
Where an EIA applies, a planning application in London cannot progress without a legally compliant ecology assessment in place.
London’s planning landscape produces consistent EIA considerations:
• Thames corridor and tributaries including the Lea, Brent and Wandle — hydrology, ecology and flood defence infrastructure
• Opportunity Areas such as Old Oak Common, Nine Elms and Stratford — cumulative urban intensification impacts
• Historic and protected landscapes in Richmond Park, Hampstead Heath and Greenwich — nationally significant habitats and landscape character
• Legacy industrial sites in Silvertown and Beckton — contamination and brownfield biodiversity
• Green Belt transition zones around Outer London boroughs — hedgerow, woodland and species connectivity
These locations frequently anchor EIA screening arguments.
Our Environmental Impact Assessment services support all London Local Planning Authorities, delivering precise ecological data to ensure seamless application processing and regulatory compliance.
London local planning authorities (LPA) are obligated to consider the Wildlife & Countryside Act 1981, the Habitats Regulations, and the NERC Act 2006 in their decision-making process. LPAs use an Environmental Impact Assessment (EIA) to provide a comprehensive evaluation of all potential environmental impacts. These include ecological risks, such as evaluating protected species in London projects, to ensure a holistic understanding of a project’s implications.
Without a detailed EIA in London, applications risk delays due to incomplete environmental assessments, seasonal survey requirements, or additional conditions pending further evidence to address ecological concerns.
Environmental Impact Assessments (EIA) in London must be precise, proportionate and defensible under challenge. We scope tightly to legal triggers, match survey effort to real risk, and structure reporting so that planning officers, consultees and inspectors can rely on it without hesitation.
Our EIA meets the evidence requirements set by London Local Planning Authorities and delivers:
All evidence is prepared for legal scrutiny, committee reporting and public consultation in London.
Review of proposal, screening opinion and environmental sensitivities to define ecology scope.
Targeted habitat and species surveys using nationwide methods consistent with CIEEM and Natural England.
Construction and operational effects evaluated with clear significance reasoning.
Policy-linked ecology chapter ready for submission within the Environmental Statement.

An Environmental Impact Assessment is a process used to assess the likely environmental effects of a development before planning permission is granted. In London, this is particularly important for large and complex schemes where impacts on surrounding communities and infrastructure must be carefully considered.
An EIA may be required where a development is likely to have significant environmental effects. In London, this often applies to major residential schemes, tall buildings, mixed use developments, and large infrastructure projects. A screening opinion from the Local Planning Authority will confirm whether an assessment is needed.
High density developments may require an Environmental Impact Assessment where they could significantly affect the surrounding area. In London, this includes impacts on transport, air quality, daylight and sunlight, noise, and neighbouring properties.
Yes, tall buildings may require an EIA, particularly where they are located in sensitive areas or have a significant visual or environmental impact. Assessments may include effects on skyline, heritage assets, and local character.
Common factors include air quality, noise, transport, townscape and visual impact, daylight and sunlight, and effects on neighbouring uses. Ecology can also be relevant, particularly in areas with green spaces or water features.
Transport is a key consideration due to the scale and complexity of London’s infrastructure. An EIA will assess impacts on road networks, public transport, walking and cycling routes, and overall accessibility.
An Environmental Impact Assessment provides detailed evidence to support a planning application. In London, where planning scrutiny is high, it helps demonstrate that environmental impacts have been properly considered and mitigated.
An EIA may assess how a development affects nearby residents and businesses, including impacts such as noise, air quality, daylight, and privacy. This is particularly important in London’s dense urban environment.
EIA and planning applications are managed by the relevant London borough depending on the site location, alongside

An Environmental Impact Assessment helps identify environmental constraints early, ensures appropriate technical work is completed, and provides clear evidence to support the planning application. In London, this can help reduce risk and support a smoother decision making process.
