If you are planning a house extension, an infill plot or a larger residential scheme in this part of north Derbyshire, the daylight requirements in Bolsover are something to get right from the outset. Bolsover District covers the market town itself, with its dramatic castle on the ridge, as well as Clowne, Shirebrook, Creswell and the surrounding former coalfield villages. The way daylight and sunlight are assessed here flows directly from the District's adopted Local Plan and its supporting design guidance, and this article explains how the pieces fit together.
Which plan applies in Bolsover?
The relevant development plan is the Local Plan for Bolsover District, which the Council adopted on 4 March 2020. It is a single, comprehensive plan covering the whole district and provides the up-to-date policy basis for determining planning applications. A point worth noting for applicants: it is Bolsover District Council, not Derbyshire County Council, that acts as the local planning authority for most development here. The County Council deals chiefly with matters such as minerals, waste and education, so for a residential proposal it is the District's Local Plan you need to read.
The design and amenity policies behind a daylight assessment
Several policies in the 2020 Local Plan combine to control daylight, sunlight and overshadowing impacts.
Policy SC3 - quality of design
Policy SC3 is the District's principal design policy, setting the standard and quality of design expected from new development. It seeks a high-quality, sustainable built environment, and for major or sensitive proposals the Council may refer schemes to an independent Design Review Panel. Daylight and sunlight are an inherent part of good design under this policy: a layout that fails to provide adequate light to its own rooms, or that overshadows its neighbours, is unlikely to be regarded as well designed.
Policy SC2 - sustainable design and construction
Policy SC2 addresses sustainable design and construction. Good orientation, sensible window placement and access to natural light all sit comfortably within its sustainability objectives, reinforcing the case for daylight to be considered early in the design process.
Policy SC11 - Environmental Quality (Amenity)
Policy SC11 is the amenity policy that most directly engages daylight and sunlight concerns. It requires that, by reference to its siting, scale and design, a proposal should not result in unacceptable overbearing or overshadowing effects, or a significant loss of privacy, for neighbouring occupiers. Overshadowing and overbearing impact are exactly what a daylight and sunlight assessment is built to quantify, so SC11 is usually the policy a case officer turns to when a neighbour raises a light objection.
Design guidance: the Successful Healthy Places SPD
To support these policies, Bolsover has adopted the Successful Healthy Places Supplementary Planning Document, prepared jointly with North East Derbyshire District Council. The SPD informs Policy SC3 by giving practical guidance on placemaking, the design of buildings and landscaping, including matters such as the spacing and orientation of homes. It builds on the long-standing Successful Places tradition of joint design guidance across this group of authorities.
The SPD is the place to look for design expectations on separation distances and layout, but it does not set out a numerical daylight test. Where a specific overshadowing or daylight impact is in dispute, the technical assessment is carried out using national methodology rather than the SPD itself.
Daylight requirements in Bolsover: the standards used
Bolsover, in common with most English districts, does not publish its own daylight figures. The amenity tests in Policies SC3 and SC11 are applied using nationally recognised guidance, given weight through the National Planning Policy Framework's expectations on good design and amenity. In practice that means:
- BRE Report BR 209 (2022), Site Layout Planning for Daylight and Sunlight - the standard reference for impact on neighbours, using the Vertical Sky Component and no-sky-line (daylight distribution) tests for daylight, and the Annual and Winter Probable Sunlight Hours tests for sunlight. It is also used to check the daylight that a proposed dwelling will receive.
- BS EN 17037 Daylight in Buildings - the European standard increasingly cited for daylight provision inside new homes.
A report prepared against these standards translates the qualitative language of the Local Plan - "unacceptable overshadowing", "significant loss of privacy" - into measurable results an officer can rely on.
Local factors that shape light in Bolsover
Two features of the District stand out when assessing daylight and sunlight:
- Ridgeline and valley topography. Bolsover town sits on a prominent ridge, and the wider district falls away into the valleys of the former coalfield. Sites on sloping ground need cross-sections, not just plans, because changes in level can significantly alter overshadowing between properties.
- Sensitive heritage and landscape settings. Bolsover Castle and the internationally important Creswell Crags lie within the district. Around such heritage assets, scale and massing are tightly controlled, which interacts with daylight and sunlight: a design that respects heritage massing constraints will often also need careful checking of its light impact on close neighbours.
- Coalfield regeneration sites. Former colliery land around Shirebrook, Clowne and Creswell continues to come forward for housing, where the internal daylight of new homes is as important as the impact on existing ones.
