Daylight requirements in Charnwood are a recurring consideration for anyone planning a house extension, an infill dwelling or a larger residential scheme across Loughborough, Shepshed, Syston, Mountsorrel and the villages of the Charnwood Forest. Charnwood Borough Council is the local planning authority (LPA) for this part of Leicestershire — the county council does not determine these applications — and it assesses the effect of new development on the daylight, sunlight and general amenity of neighbouring homes when it decides planning applications. This article sets out how those daylight requirements work in Charnwood, which local policies apply, and where the recognised technical guidance fits in.
The local planning framework in Charnwood
On 19 January 2026 the Council adopted the Charnwood Local Plan 2021-37, which now sets the development strategy for the borough up to 2037. This new plan replaces the previous Core Strategy as the up-to-date starting point for decisions, and its design policy is the place where daylight and sunlight considerations are anchored.
The key policy is Policy DS5: High Quality Design. It requires new developments to make a positive contribution to Charnwood and, among other things, to:
- protect the amenity of people who live or work nearby and those who will live in the new development;
- respect and enhance the character of the area, having regard to scale, density, massing, height, layout and access; and
- provide attractive, safe and well managed public and private amenity spaces.
The reference to protecting the amenity of neighbouring occupiers is the route through which daylight, sunlight, overshadowing and loss of outlook are weighed. Policy DS5 also notes that an independent design review may be required for strategic or sensitive proposals, funded by the applicant, and that permission will be refused for development that is not well designed.
The plan's supporting text confirms that detailed guidance — “particularly with respect to house extensions, amenity, car parking and crime prevention†— is set out in an appendix to the plan and should be read alongside the design policy. The plan also stresses that good design “will add to the amenity of an area and protect existing amenitiesâ€, which is precisely the test a daylight and sunlight assessment helps to evidence.
Daylight requirements in Charnwood: the technical guidance
Charnwood does not publish a separate numeric daylight or sunlight standard of its own. Instead, the borough operates a longstanding Charnwood Design Supplementary Planning Document (Design SPD), adopted in January 2020, which provides detailed advice on residential design, including house extensions, overlooking and the protection of neighbours' amenity. The Design SPD sits beneath the Local Plan design policy and is a material consideration in decisions.
Where the impact on daylight and sunlight needs to be quantified, the recognised national methodology is applied. The standard reference is the Building Research Establishment (BRE) guide Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice, in its current 2022 third edition (often cited as BR 209). This document, together with the daylight provision recommendations of BS EN 17037, provides the numerical tests — such as the Vertical Sky Component (VSC), the No Sky Line / daylight distribution test, and the Annual Probable Sunlight Hours (APSH) test — that planners and consultants use to judge whether a neighbouring window or garden would suffer a material loss.
The use of this guidance flows from national policy. The National Planning Policy Framework (NPPF) expects new development to provide a high standard of amenity for existing and future occupiers, while allowing authorities to take a flexible approach where an area's character or an efficient use of land justifies it. Charnwood's design policy applies that national expectation locally, and the BRE and BS EN 17037 methodologies are the evidence base used to demonstrate compliance.
In short: there is no Charnwood-specific daylight figure to hit. The borough relies on Policy DS5 and the Design SPD to require that amenity is protected, and the BRE BR 209 (2022) guide and BS EN 17037 are the technical tools used to prove it.
What this means in practice for applicants
Whether you are a householder in Quorn extending to the rear or a developer bringing forward a backland plot in Birstall, the practical questions are the same:
- Will the proposal materially reduce daylight to habitable-room windows of adjoining properties, measured against the BRE VSC and daylight distribution tests?
- Will it cause unacceptable overshadowing of a neighbour's garden or amenity space, judged on the BRE sunlight-on-ground test, especially relevant near the open settings of the Charnwood Forest fringe?
- Will sunlight to main living rooms facing within 90 degrees of due south be reduced below the APSH thresholds?
Addressing these points with a robust assessment up front reduces the risk of objections, refusals or delays at Plans Committee, and gives the case officer the evidence they need to apply Policy DS5 confidently.
Local context worth noting
Charnwood is varied: the compact terraced streets and student-housing pressures around Loughborough University contrast with the conservation-area grain of villages such as Mountsorrel and Rothley, and with the sensitive landscape of the Charnwood Forest. Tighter urban plots tend to raise daylight and overlooking issues most acutely, while edge-of-village and Forest-fringe sites more often raise overshadowing and outlook concerns. A site-specific approach — rather than a one-size-fits-all rule — is exactly what both the BRE guide and Policy DS5 anticipate.
