Winchester's cathedral city centre is anchored by the medieval cathedral close, with Georgian and Regency townhouses lining streets like Kingsgate Street, Victorian housing across the inner suburbs, and modern infill on cleared plots near the centre. The town sits within multiple overlapping conservation areas, with almost all older stock carrying windows that have received natural light for centuries, well past the 20-year easement threshold under the Prescription Act 1832. Conservation area work, infill, and significant rear extensions routinely raise rights of light questions, with Winchester City Council planning consent leaving the legal position untouched.
We act on Winchester schemes from the Hampshire office, with reach across Alresford, Twyford, and the surrounding villages, supported by colleagues in London and Essex. CHP is RICS regulated and has been advising on rights of light since 2004. The local Hampshire team handles this work faster than London-led practices, and where the work overlaps with the Party Wall etc. Act 1996 we run party wall services from the same point of contact.


The starting point on every Winchester project is a free initial assessment to identify which neighbouring windows could be affected by the proposed scheme and which carry the 20-year easement. From there, we use specialist rights of light software to model existing and proposed light levels for each affected room, with the results tested against the Equivalent First Zone and the 50/50 rule to quantify any loss in legal terms.
Where the figures show a likely infringement, the cutback analysis tests design variations including reduced height, set-back upper floors, and adjusted fenestration until the scheme works for both the planning case and the rights of light position. Conservation area constraints in Winchester often shape the cutback options available, and our rights of light assessments overview sets out the broader method for design teams working on the historic stock. The bespoke surveying service means each scope is set against the specific Winchester project.
In most cases, yes. The path forward is usually a negotiated settlement with the adjoining owner, paid in exchange for a release of their legal right to light against the new building. Damages are typically calculated by reference to the share of the development profit attributable to the part of the scheme causing the infringement, and the figure is significantly easier to predict when the rights of light position has been quantified at the design stage. Injunctions are rare where matters are handled properly and early.
Planning consent from Winchester City Council does not resolve the rights of light position, so the legal track has to run alongside the planning track on every Winchester scheme that sits close to existing windows. Where rooftop or upper-floor work is in play, we can also bring in airspace development advice from the same team.
