Environmental Considerations in Land Development: What UK Landowners Need to Know

For UK landowners considering development, understanding environmental requirements isn't just good practice—it's essential for project success. Environmental considerations play a crucial role in obtaining planning permission and can significantly impact your development's timeline and costs. This guide provides key insights for landowners looking to navigate the complex landscape of environmental regulations in the UK.

Biodiversity Net Gain Requirements

Since January 2024, all new developments in England must deliver a minimum 10% biodiversity net gain (BNG). This means your development must leave biodiversity in a better state than before. With an estimated 300,000 planning applications annually expected to be influenced by this requirement, it’s clear that biodiversity considerations are now central to the planning process. Key points include:

• The need for a pre-development ecological survey to assess current biodiversity. Learn more about the requirements from Natural England.

• Creation of a biodiversity gain plan, outlining how the project will improve biodiversity.

• Options for on-site habitat creation or off-site compensation through registered sites.

• A 30-year commitment to maintaining biodiversity improvements, as outlined in the Environment Act 2021.

With 41% of UK species declining over the past 50 years, ensuring biodiversity net gain is not only a regulatory requirement but a crucial step toward reversing this trend.

Tree Preservation Orders (TPOs)

Trees can significantly impact your development potential:

• TPOs protect specific trees, groups of trees, or entire woodlands. Consult your local council to determine if any TPOs apply to your site using the Planning Portal.

• Removal or work on protected trees requires local authority permission, even for routine maintenance.

• Penalties for breaching TPOs can include unlimited fines under the Town and Country Planning Act 1990.

• Even unprotected trees may need assessment as part of the planning process, especially if they contribute to the local environment.

Protected Species Assessments

The UK has strict regulations protecting various species, and you may need to conduct surveys for:

• Bats, especially if you have existing buildings or mature trees. There are 18 species of bats in the UK, all legally protected under the Wildlife and Countryside Act 1981.

• Great crested newts, a species protected by European law. Newt surveys are essential for projects near water bodies.

• Badgers, which have specific protections under the Protection of Badgers Act 1992.

• Nesting birds, subject to seasonal restrictions from March to August under the Wildlife and Countryside Act.

Each year, bat-related considerations alone influence approximately 5,000 planning applications, underscoring the importance of protected species assessments.

Survey Timing Considerations

Many ecological surveys are season-dependent:

• Great crested newts: Mid-March to mid-June

• Bats: May to September

• Badgers: February to April or October to November

• Birds: March to August (breeding season)

For accurate results, it’s essential to plan surveys in advance based on the specific species' active periods.

Flood Risk Assessment

With increasing climate concerns, flood risk assessment is crucial for sustainable development:

• Required for developments in Flood Zones 2 and 3, as designated by the Environment Agency.

• Assesses risks from surface water, groundwater, and river flooding.

• May necessitate the installation of sustainable drainage systems (SuDS) to mitigate risks.

• Can influence building design and site layout, impacting planning permission outcomes.

Given that one in six properties in England is at risk of flooding, a thorough flood risk assessment can safeguard your investment and ensure compliance with local planning authorities.

Soil Quality and Contamination

Understanding your land’s history is vital for development success:

• A Phase 1 Environmental Assessment is required for most developments to identify any previous contamination.

• Soil contamination testing may be necessary if there’s historical industrial use. Learn more about requirements from DEFRA.

• Remediation measures can be costly if contamination is discovered, potentially impacting development viability.

The UK is estimated to have around 300,000 hectares of potentially contaminated land, making soil assessments essential in ensuring project safety and feasibility.

Sustainable Development Requirements

Modern developments must demonstrate sustainability to meet current standards:

• Incorporate energy efficiency measures, such as solar panels or improved insulation.

• Consider renewable energy sources and electric vehicle charging provisions.

• Use sustainable building materials that minimize environmental impact.

• Implement effective water management strategies, including rainwater harvesting systems.

In 2023, 74% of new homes in the UK included sustainable features, reflecting the nation’s commitment to greener developments.

Archaeological Considerations

The UK's rich history means archaeological factors must be taken into account:

• A desktop archaeological assessment may be required for planning applications.

• Trial trenching may be needed if potential archaeological significance is found.

• Watching briefs may be mandated during groundworks if historical artifacts are suspected.

• If significant finds are discovered, preservation may be required under the National Planning Policy Framework.

Historic England reports that one-third of major planning applications require some form of archaeological assessment, highlighting the importance of considering the historical context of your site.

Environmental Impact Assessment (EIA)

Larger developments may require an EIA to examine the full environmental implications:

• Air quality impacts, especially in urban areas.

• Noise and light pollution considerations, particularly near residential areas.

• Traffic effects that could impact local infrastructure.

• Landscape and visual impact, essential for developments in scenic or rural locations.

In 2022, only 21% of EIA applications were approved, reflecting the rigorous scrutiny applied to environmental factors in major projects.

Practical Steps for Landowners

1. Early Assessment

   • Commission preliminary ecological surveys to identify any potential issues.

   • Research historical land use to uncover any contamination risks.

   • Check your local authority's environmental requirements using the Planning Portal.

2. Professional Support

   • Engage qualified ecological consultants for expert advice.

   • Work with environmental planning specialists to navigate complex regulations.

   • Maintain open communication with your local planning authority to stay compliant.

3. Timeline Planning

   • Account for seasonal survey windows when setting project timelines.

   • Build in extra time for mitigation measures if needed.

   • Prepare for potential delays due to unexpected findings.

4. Budget Considerations

   • Factor in the costs of ecological surveys and potential biodiversity offsets.

   • Include expenses for mitigation measures, such as habitat creation or remediation.

   • Consider long-term maintenance costs for biodiversity and sustainability features.

     

     Common Pitfalls to Avoid

     • Ignoring seasonal survey windows, which can lead to costly delays.

     • Underestimating the importance of preliminary assessments, risking unexpected complications.

     • Failing to budget for mitigation measures, potentially derailing projects.

     • Not considering long-term maintenance, impacting the value and viability of your development.

     • Starting work without necessary surveys complete, leading to fines and legal challenges.

     Moving Forward

     Environmental considerations shouldn’t be seen as obstacles but as opportunities to create sustainable, valuable developments. Early planning and professional guidance can help you navigate these requirements effectively, leading to successful outcomes for both developers and the environment.

     Taking a proactive approach to environmental considerations can:

     • Smooth the planning process

     • Reduce unexpected delays

     • Minimise costs

     • Create more sustainable developments

     • Enhance project value
