What Corylus Planning and Environmental does

Corylus Planning and Environmental Limited is a UK-based multi-disciplinary planning and environmental consultancy established around 2005-2006 and headquartered in Yanworth, Cheltenham, Gloucestershire. The firm delivers integrated services across four core disciplines - planning, architecture, landscape architecture, and hydrology - plus specialist expertise in energy (solar farms, battery storage, renewable gas), minerals and quarrying, leisure developments, master planning, public consultation, and residential projects. It serves a horizontal mix of clients including residential developers, renewable energy operators, quarry owners, holiday and leisure developers, landowners, and educational institutions, with named engagements spanning the Lakes by Yoo development (over 17 years), Raymond Brown Quarry Products' Brickworth and Binnegar quarries, Rivan Industries' Renewable Natural Gas pilot, and individual solar farm planning applications of up to 49.9MW.

Corylus operates as a single private limited company under founder and Director Phillip Duncan, alongside Associate Director of Planning Chris Cox and a multidisciplinary team including Principal Landscape Architects, a Principal Hydrologist, Senior Planners, and Architectural Technicians. Revenue is generated through project-based professional consultancy fees, supplemented by a freemium lead-generation model offering free 30-minute consultations across planning, landscape architecture, and environmental services. The firm holds chartered-practice accreditations from RIBA, RTPI, ARB, the Landscape Institute, RICS, and CIWEM, and is recognised as a Landscape Institute Registered Practice. Marketing is primarily content-driven via website news, LinkedIn, Instagram, and public consultation events, with no external institutional investment, no subsidiaries, and no M&A activity disclosed.

The firm expanded its physical footprint in July 2024 by acquiring adjacent office space in Yanworth to accommodate team growth, and continues to publish quarterly newsletters through mid-2026, indicating active ongoing operations. Notable credentials include successful planning appeal outcomes for solar farms at 40MW (Cornwall), 49.9MW (Buckinghamshire), and 22.2MW (Wakefield), a 90% Biodiversity Net Gain at Blythe Solar Farm Extension, and a 2017 Mineral Planning Association Biodiversity - Planned Restoration award for the Brickworth Quarry restoration scheme.
