Understanding the daylight requirements in Melton Borough Council matters for anyone proposing a house extension, an infill dwelling or a larger residential scheme across this rural Leicestershire borough, centred on the historic market town of Melton Mowbray - famous for its pork pies and Stilton cheese - and taking in the many villages of the Vale of Belvoir and the Wolds. Melton Borough Council is the local planning authority (LPA); Leicestershire County Council is the upper-tier authority but does not determine most householder and residential planning applications. This guide explains how daylight and sunlight are considered locally, which adopted documents apply, and what an assessment to recognised national standards involves.
Daylight requirements in Melton Borough Council: the policy framework
The development plan for the borough is the Melton Borough Local Plan 2011-2036, which was adopted on 10 October 2018. It provides the strategic and development management policies used to determine planning applications across Melton Mowbray and the surrounding villages.
For daylight, sunlight and residential amenity, the key policy is:
- Policy D1 - Raising the Standard of Design, the borough's principal design policy. Among its criteria, criterion d expects development to avoid an unacceptable "loss of light" to neighbouring properties, alongside protecting privacy and avoiding overbearing or overshadowing impacts.
That "loss of light" wording is the hook on which daylight and sunlight questions hang in Melton. Where a proposed extension or new dwelling could materially reduce the daylight or sunlight reaching a neighbour's windows or garden, an officer needs evidence to judge whether the effect crosses from acceptable to unacceptable - and that is precisely what a daylight and sunlight assessment is designed to provide.
The Design of Development SPD
Melton Borough Council supports Policy D1 with a Design of Development Supplementary Planning Document, adopted on 24 February 2022. The SPD expands on the council's design expectations and provides more detailed guidance on how proposals should respond to their context, including the relationship between buildings and the protection of neighbouring amenity. It is the practical companion to Policy D1 and a material consideration in the determination of applications, so applicants should read the two together when designing a scheme.
How BRE BR 209 applies
Melton does not publish a standalone daylight and sunlight Supplementary Planning Document with its own numerical daylight test. Where a proposal needs to be assessed for its effect on daylight and sunlight, the recognised national methodology applies. That methodology is the Building Research Establishment guidance, BRE BR 209: Site Layout Planning for Daylight and Sunlight - A Guide to Good Practice (2022 edition), read alongside the British Standard BS EN 17037 on daylight in buildings.
These documents are applied through Policy D1 and the Design of Development SPD, and within the framework of the National Planning Policy Framework (NPPF), which supports making efficient use of land while securing well-designed places and a good standard of amenity for existing and future occupiers. In short, BR 209 gives objective measures to the qualitative "loss of light" criterion in Policy D1, so that the impact of a proposal can be demonstrated rather than simply argued.
What a daylight and sunlight assessment involves
A BRE-based assessment generally considers two questions: the daylight and sunlight enjoyed by neighbouring properties, and the daylight and sunlight that future occupiers of the proposed development will receive. The principal tests include:
- Vertical Sky Component (VSC) - the amount of skylight reaching the centre of a neighbour's window, with a guideline value of 27%, or no worse than 0.8 times its former value;
- Daylight distribution (the no-sky line) - how daylight is spread across the depth of a room;
- Annual Probable Sunlight Hours (APSH) - the sunlight reaching windows with a significant southerly aspect, assessed across the whole year and the winter period;
- Overshadowing of gardens and amenity areas - using the sun-on-ground test on the equinox.
A clear, BRE-compliant report helps a Melton planning officer apply the "loss of light" criterion in Policy D1 and the guidance in the Design of Development SPD. It is particularly valuable for two-storey rear and side extensions in the established streets of Melton Mowbray, infill and backland plots, and new homes on the edges of the town and along corridors such as the Melton Mowbray Distributor Road, where layout and orientation can affect the result. A robust assessment cannot promise consent, but it gives officers the evidence to reach a sound decision and helps applicants design out problems before submission.
Common situations across Melton borough
Typical daylight and sunlight questions in the borough include rear extensions projecting alongside a shared boundary, two-storey side additions near a neighbour's flank windows, conversions and subdivisions that create new habitable rooms, and village infill where a new dwelling sits close to existing homes. Testing these against BR 209 early in the design process helps confirm whether a scheme is likely to satisfy Policy D1, or whether the height, depth or position needs adjusting before plans are submitted.
