Do You Need a Habitat Management and Monitoring Plan in London?
Where Biodiversity Net Gain applies, an HMMP is required to legally secure how habitats will be managed and monitored for 30 years after development. In London, you will need an HMMP if your planning permission includes a biodiversity condition that requires long-term habitat creation or enhancement.
Within Greater London, LPAs most frequently specify HMMP requirements where schemes involve:
• High-density residential and commercial redevelopment across Opportunity Areas and Housing Zones
• Infrastructure, transport-led growth and intensification linked to the DLR, Crossrail/Elizabeth Line and orbital rail corridors
• Estate regeneration and urban edge development in outer London boroughs with strategic open space interfaces
• River systems, marsh habitats and green/blue infrastructure associated with the Thames corridor and tributary networks
Incorrect HMMP structure typically results in delayed discharge of biodiversity conditions.
We provide Habitat Management & Monitoring Plans across London, supporting projects in Central, North, South, East and West London, including Westminster, Camden, Hackney, Croydon, Ealing, Lewisham, Islington, Greenwich, Richmond and all surrounding boroughs and urban green networks.
Why Planning Authorities in London Require an HMMP
Planning Authorities across London require HMMPs to secure the 30-year delivery of habitats created through Biodiversity Net Gain, as set out under the Environment Act 2021. The HMMP provides the legally enforceable framework for management, monitoring and reporting. Without an approved HMMP, long-term biodiversity obligations remain legally unsecured.

How the HMMP Process Works
We produce Habitat Management & Monitoring Plans aligned to London’s policy expectations.
Key HMMP Deliverables for London Projects
Your HMMP is structured to meet statutory planning requirements in London and typically includes:
Habitat management objectives and prescriptions — how each habitat will be maintained and enhanced
30-year maintenance schedule — practical, year-by-year actions
Monitoring framework and reporting structure — how success is measured and documented
Legal responsibility and delivery framework — aligned with planning conditions, legal agreements or conservation covenants
This ensures long-term ecological compliance is secured, auditable and enforceable.

FAQ - HMMP in London
Do London boroughs apply consistent requirements for Habitat Management and Monitoring Plans?
No. Each London borough determines its own validation and discharge approach, although all operate within the framework of the London Plan and national Biodiversity Net Gain legislation. While the statutory 10 percent requirement is consistent, the level of detail expected within an HMMP can vary between boroughs such as Camden, Croydon or Greenwich. Developers should confirm borough specific expectations before submitting discharge applications.
How does the London Plan influence HMMP preparation?
The London Plan places strong emphasis on urban greening, biodiversity enhancement and multifunctional green infrastructure. Where development proposals rely on habitat creation to meet Biodiversity Net Gain targets, the HMMP must demonstrate that those features are deliverable, measurable and capable of long term management within dense urban settings.
Are green roofs and vertical greening systems required to be included in a London HMMP?
Yes, where such features contribute to biodiversity units. Green roofs, living walls, podium planting and landscaped terraces that are counted within the Biodiversity Metric must have clearly defined ecological objectives and measurable condition targets within the HMMP, not simply maintenance specifications.
How are estate regeneration and phased developments handled in London?
For estate regeneration or large mixed use schemes delivered in phases, boroughs may accept phased HMMPs provided that each phase clearly sets out habitat delivery, target conditions and monitoring intervals. However, the full 30 year management obligation must still be secured and clearly documented.
Who is typically responsible for long term habitat management in London developments?
Responsibility often transfers to a management company or estate operator following completion. The HMMP must clearly define who holds legal responsibility for management and monitoring for the full 30 year period, particularly where secured by planning condition or Section 106 agreement.
What monitoring evidence do London boroughs expect?
Boroughs expect monitoring reports that clearly assess whether habitats are progressing toward their agreed target condition. Reports should reference the Biodiversity Metric assumptions submitted at planning stage and provide measurable evidence rather than general site observations.
What are common reasons HMMPs are delayed in London?
Common issues include lack of measurable habitat targets, failure to align with Biodiversity Metric outputs, unclear management responsibilities within complex ownership structures and insufficient detail for engineered or rooftop habitats.
Where can developers review borough planning requirements?
Developers should consult the planning portal of the relevant London borough before submitting discharge applications. For strategic planning policy context, the London Plan is available at https://www.london.gov.uk/programmes-and-strategies/planning/london-plan.
Can off site biodiversity units outside London be linked to a London development?
Where off site land is used to achieve Biodiversity Net Gain, the HMMP must clearly define management prescriptions, monitoring arrangements and the legal securing mechanism. The plan must align with the approved Biodiversity Gain Plan and any associated planning obligations.
How can ProHort support HMMP preparation in London?
ProHort prepares technically robust Habitat Management and Monitoring Plans tailored to London borough scrutiny levels. We ensure habitat targets are measurable, management frameworks are clearly defined and monitoring schedules are realistic for dense urban and mixed use schemes, reducing risk at condition discharge and throughout the 30 year obligation period.
