1. Rights of Light, Daylight, Sunlight
and Overshadowing
BENEFITS OF OUR SERVICE
Here at Anderson Wilde and Harris we have the benefit of an in-house CAD team. This
gives us the advantage of quick and clear communication when preparing or amending
3D models whether you’re a homeowner, neighbour, or developer, we can help you
determine if and to what extent, you’ll be infringing on the Rights of Light of adjoining
owners.
Through years of experience we are able to provide you with detailed analysis and
advice by establishing strong communication from beginning to end; and if there is an
infringement, we can negotiate for compensation for the “release of light”.
DAYLIGHT, SUNLIGHT AND OVERSHADOWING
Daylight, Sunlight and Overshadowing are planning considerations which differ from
Rights of Light.
Planners from the local council may be concerned about the potential loss of light to
neighbouring properties as a result of new developments.
Homeowners may fear they will suffer a loss of daylight or sunlight if their homes, yards,
or gardens are overshadowed by new development. As such, Anderson Wilde & Harris
can provide in-depth analysis, calculations and reports for the developer.
Utilizing guidelines set forth by the Building Research Establishment’s guide to good
practices, we also measure your Vertical Sky Component and Average Daylight Factor
to guarantee you meet all requirements.
RIGHTS OF LIGHT
Rights of Light is an easement that an aperture can acquire by being in place for 20
years. The easement allows the owners the right to receive a minimum amount of light
through the aperture and into a room. This includes a right to the light that passes
over neighbouring land.
If a property experiences a loss of light down to 50 percent, or what is deemed
‘adequately lit’, the owner may seek an injunction or attempt to negotiate a compensation
fee.
Anderson Wilde & Harris have experience with Rights of Light matters for all respective
parties and are able to provide assessments and surveys using 3-D modelling to
negotiate compensation settlements. Existing

• When Do I Need A Daylight And Sunlight Report?
Planners from the local council may be concerned by
the impact large developments or developments in
built up areas will have on the light in the neighbouring
properties. If they are, then they may request a
Daylight and Sunlight report to demonstrate that the
neighbours won’t be affected.
• Is A Daylight And Sunlight Report Different To A
Rights Of Light Report?
Yes. A Daylight and Sunlight report is different to a
Rights of Light report. Daylight and sunlight are planning
considerations. Rights of Light is a common law right.
During the planning process planners are usually only
concerned with planning considerations.
DAYLIGHT AND SUNLIGHT QUESTIONS
• How Much Does A Daylight And Sunlight Report Cost?
This depends on the size of the development and the
number of neighbouring properties that need to be
considered as part of the assessment.
