London’s brownfield land, railway embankments, urban parks, scrub and river corridors provide suitable habitat for reptiles including slow worms, grass snakes and common lizards.
A reptile survey identifies species presence and assesses whether proposed works could affect them. Ecologists conduct repeat site visits using refugia and visual search techniques to record reptiles over time. Survey results help inform planning applications and ensure compliance with wildlife legislation. London boroughs frequently request surveys where semi-natural habitats may be impacted.
You may need a reptile survey if your project involves:
brownfield redevelopment across Greater London
clearance of unmanaged grassland or scrub
works along railway lines, canals or rivers
infrastructure or regeneration schemes affecting green spaces
sites identified as having reptile potential in a Preliminary Ecological Appraisal (PEA)
A postcode check can quickly reveal whether your site sits within likely reptile habitat.
We provide reptile surveys across London and surrounding boroughs.
London planning authorities require reptile survey evidence where suitable habitat is present to ensure development complies with the Wildlife & Countryside Act 1981 and national planning policy. Without early, proportionate evidence, applications are frequently delayed through validation queries, requests for further ecological information, or seasonal survey constraints that can halt project programmes and necessitate design amendments.
We take a practical, proportionate approach, carrying out reptile presence checks and habitat assessments, identifying areas of suitable habitat, and inspecting grassland, scrub, rough ground, and brownfield sites before works begin. Our Reptile Survey reports provide clear mitigation and timing recommendations, are fully LPA-ready, and outline any precautionary measures required to protect reptiles. We also give straightforward next steps for contractors, focusing on clarity and practical guidance so your project can proceed safely and confidently.
We provide a clear, proportionate, practical approach which includes:

Need a reptile survey in London? Let’s confirm your site’s requirements and keep your project on track.
Yes. Although central London is heavily urbanised, reptiles can still occur on suitable habitats associated with redevelopment sites, railway embankments, canals, brownfield land, parks and unmanaged open spaces. Every site should be assessed on its ecological merits rather than its postcode.
Commercial sites that have been vacant for several years often develop rough grassland, scrub and other unmanaged vegetation that can support reptiles. Before redevelopment begins, an ecologist can assess whether these habitats present a constraint that should be addressed during the planning process.
Yes. Railway embankments, transport corridors and associated green infrastructure can create long, connected habitat networks that reptiles may use for shelter, basking and movement. Developments adjacent to these areas may require ecological assessment where suitable habitat could be affected.
Yes. Even high density residential and mixed use developments can require reptile surveys where the site includes suitable habitat before construction begins. The future scale of the building is less important than the ecological value of the land that will be affected during development.
Potentially. Small urban sites, including former garages, vacant land, redundant commercial premises and development gaps, can contain suitable reptile habitat if they have remained unmanaged for long periods. An initial ecological assessment will determine whether reptile surveys are necessary.
Where development proposals could affect suitable reptile habitat, London Borough Councils may request reptile survey information before determining a planning application. Requirements vary between boroughs depending on local planning policy and site conditions. Planning guidance can be found through the Greater London Authority alongside the relevant London Borough:
Yes. Reptile surveys often form part of the wider ecological evidence base for developments. The information collected can support Biodiversity Net Gain strategies, Urban Greening initiatives and ecological mitigation proposals by identifying existing habitat value before development takes place.
If reptiles are present, the development can often proceed following appropriate mitigation. Depending on the circumstances, this may involve retaining habitat where possible, creating replacement habitat, carefully sequencing vegetation clearance or implementing supervised translocation where required.
Early ecological surveys allow architects and design teams to understand environmental constraints before layouts are fixed. This provides greater flexibility to accommodate ecological recommendations, helping reduce planning risks, redesign costs and delays later in the project.
ProHort provides professional reptile surveys for residential, commercial, infrastructure and regeneration developments across London. Our experienced ecologists understand the complexities of urban planning and produce robust, planning ready survey reports that help developers, architects, planning consultants and landowners satisfy Local Planning Authority requirements while protecting biodiversity.
