Rights of Light

We are highly experienced Rights of Light and Daylight and Sunlight experts. We can advise on complex developments, supply planning reports, and provide many other services as listed below, which can support the success of your project.


Rights of Light in England and Wales

In England and Wales, a ‘right to light’ is an easement that is acquired by a dominant owner (adjoining owner), which carries the right to receive sufficient natural light through defined apertures, such as windows, over a servient owner (developer/building owner). Rights to light easements are civil, privately enforceable rights that fall under the law of nuisance. We advise developers, funders, architects, and adjoining owners, providing expert advice concerning all properties ages and types across the UK in this regard.


Daylight and Sunlight

Daylight and Sunlight planning is based on the BRE Report “Site layout planning for daylight and sunlight: a guide to good practice (BR209)”, which advises on how to achieve good access to daylight and sunlight for both neighbouring properties and within applicable developments themselves.  We can support your projects by providing assessments and reports, to determine both the impacts to existing buildings, amenity areas, and the adequacy within new proposed developments.
