What Anstey Horne does

Anstey Horne is a UK specialist surveying and property consultancy practice, founded in 1795 and headquartered in London. The firm operates across nine UK offices (London, Birmingham, Bristol, Brighton, Cardiff, Leeds, Manchester, Norwich, Plymouth) and delivers a tightly defined portfolio of interrelated services: Rights to Light and Daylight & Sunlight assessments (with sub-offerings in solar glare and solar panel assessments), Party Wall and neighbourly matters (including boundary disputes and security for expenses), Building Consultancy, Building Safety Services, Fire Consultancy (EWS1, FRAEW/PAS9980, FRAs, compartmentation), Cost Consultancy and Project Management. Client segments span developers, architects and planning consultants, adjoining owners, building owners/freeholders, registered providers, managing agents, funds, lenders, local authorities, and commercial occupiers — i.e., the full lifecycle of UK development and built-asset risk.

The technology stack is built around advanced 3D laser scanning, CAD and proprietary or specialist analysis software, including detailed 3D city models for London, Birmingham, Manchester and other urban centres, a bespoke digital reality modelling process for glare-risk simulation, and a dedicated solar glare analysis tool that produces glare calendars and video simulations. Analysis methods adhere to current planning-relevant standards (BRE BR209 2022, BS EN 17037, Waldram analysis for Rights to Light) — i.e., the technology is positioned as a quality and reproducibility differentiator within established regulatory frameworks rather than as a substitute for them.

The business model is a director-led professional services practice with a UK office-based field-sales channel supplemented by phone enquiry lines (Rights to Light, Party Wall, EWS1, Building Safety) and online quote request tools. Revenue is generated on a quote-based, project-fee basis across surveying and consultancy engagements; pricing is not publicly disclosed. The firm received a £7m ($9.2m) growth investment from Business Growth Fund in April 2016; no further institutional capital event is on record. The firm claims the largest specialist Rights to Light, Daylight & Sunlight, and Party Wall teams in the UK, and the partners were instrumental in drafting the Party Wall etc. Act 1996.
