Direct peers

• Aspect Ecology: Aspect Ecology is a UK ecological consultancy providing protected species surveys, ecological impact assessment, Habitats Regulations Assessment, and biodiversity services that directly overlap with HDA's ecology offering and compete for the same ecology-only and combined commissions.
• LDA Design: LDA Design is a UK landscape architecture, urban design, and masterplanning practice that competes directly with HDA for local authority masterplanning, design codes, and LVIA work. Its integrated landscape + masterplanning offering is the most direct head-to-head peer for HDA's masterplanning team.
• Gillespies: Gillespies is a UK landscape architecture and urban design firm with comparable public realm, masterplanning, and LVIA capabilities. It serves both local authorities and private developers with a similar integrated-design ethos to HDA.
• Land Use Consultants (LUC): LUC is a UK-based multi-disciplinary environmental planning, landscape architecture, and ecology consultancy with a directly comparable service mix (LVIA, landscape character assessment, masterplanning, ecological impact assessment) for both public and private sector clients. It is the closest scale-and-scope comparable to HDA in the UK market.
• Nicholas Pearson Associates: Nicholas Pearson Associates is a UK ecological and arboricultural consultancy offering a comparable combined ecology-arboriculture service line to HDA, including BS5837 tree surveys, protected species work, and ecological input to planning applications.

Broad incumbents

• WSP UK (Environment & Planning): WSP's UK Environment & Planning business delivers landscape, ecology, EIA, and masterplanning services that overlap with HDA's offering, typically through much larger national framework commissions with housebuilders, infrastructure promoters, and government.
• Wardell Armstrong: Wardell Armstrong is a larger UK multi-disciplinary environmental, planning, and engineering consultancy that competes with HDA for landscape, ecology, and EIA work as part of a much broader portfolio including planning, minerals, and engineering services.
• SLR Consulting: SLR Consulting is a global environmental and advisory consultancy with a substantial UK practice covering EIA, ecology, landscape, and planning. It overlaps with HDA on developer-side environmental inputs but at a much larger scale and broader service breadth.
