Understanding the daylight requirements in Gedling is essential for anyone planning a house extension, an infill plot or a larger residential scheme in the borough. Gedling Borough Council is the local planning authority for Arnold, Carlton, Mapperley and the surrounding villages — Nottinghamshire County Council is not the decision-maker for these applications. This guide explains how daylight, sunlight and amenity are assessed locally, which adopted policies apply, and where a professional report can help your proposal.
Daylight requirements in Gedling: the policy framework
Gedling does not have its own numeric daylight standard. Instead, daylight and sunlight are dealt with through the borough's adopted development plan, which is read alongside national guidance. The two key documents are the Aligned Core Strategy (Part 1 Local Plan), adopted September 2014, and the Gedling Borough Local Planning Document (Part 2 Local Plan), adopted on 18 July 2018. Together these form the statutory plan against which applications in Arnold, Carlton and the villages are determined.
Because there is no local numeric metric, the technical benchmarks come from established national references: the Building Research Establishment guide Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice (BRE BR 209, 2022 edition), the daylight standard BS EN 17037, and the National Planning Policy Framework (NPPF), which requires a good standard of amenity for existing and future occupiers. These come into play through the Local Plan's amenity and design policies.
Policy LPD 32: Amenity
The most directly relevant policy is Policy LPD 32 (Amenity) in the 2018 Local Planning Document. It states that planning permission will be granted for development that does not have a significant adverse impact on the amenity of nearby residents or occupiers, taking account of potential mitigation. The factors it lists include overshadowing, overbearing impact and overlooking.
Crucially, the policy's supporting text explains how overshadowing is assessed: by “the extent to which the height, bulk and position of a building will reduce the amount of light to nearby properties,†with special consideration given to “the reduction of light to the main habitable rooms of residential properties.†This is precisely the question a daylight and sunlight assessment answers, which is why a BRE-based study is so useful in demonstrating compliance with LPD 32.
Policy 10 and Policy LPD 43: design and extensions
Design quality is governed by Policy 10 (Design and Enhancing Local Identity) of the Aligned Core Strategy, which requires development to be assessed on elements including massing, scale and proportion and the “impact on the amenity of nearby residents or occupiers.†For the borough's most common application type — home extensions — Policy LPD 43 (Extensions to Dwellings Not in the Green Belt) applies, granting permission where the proposal is in keeping with surrounding character and “would not cause a significant adverse impact on the amenity of nearby occupiers.†Loss of light to a neighbour is a recognised part of that amenity test.
The Gedling Design Code Framework
Gedling has gone further than many authorities by adopting a borough-wide Design Code Framework as a Supplementary Planning Document on 7 November 2024. It sets design requirements tailored to different scales of residential development — including separate codes for extensions and alterations and for major sites of ten or more dwellings — and asks applicants to complete a Design Code Checklist showing how each principle has been met. While the Framework is a design tool rather than a numeric daylight standard, it reinforces the need to demonstrate that new homes and extensions respect their context and protect neighbouring living conditions.
This local emphasis on observed character and well-considered massing makes early daylight and sunlight analysis valuable: it lets you test orientation, height and separation distances before the design is fixed, supporting both the Design Code submission and the LPD 32 amenity case.
What a daylight and sunlight assessment covers
A BR 209 assessment in Gedling typically looks at two things: the impact of your proposal on neighbouring properties, and the daylight and sunlight available to any new dwellings you are creating. The standard tests include:
- Vertical Sky Component (VSC) — the daylight reaching a neighbour's window, where a reading at or above 27%, or no worse than 0.8 times the former value, is generally considered acceptable.
- Daylight distribution / No Sky Line — how far daylight penetrates into a room.
- Annual Probable Sunlight Hours (APSH) — sunlight to windows facing within 90 degrees of due south.
- Overshadowing to gardens and amenity areas — the sun-on-ground test, relevant to the overshadowing factor in Policy LPD 32.
Where a scheme falls short of the guideline figures, the BRE methodology and BS EN 17037 allow for a reasoned, context-sensitive judgement — which aligns neatly with Gedling's policy language about “significant adverse impact†and professional judgement.
When you might need a report in Gedling
You are most likely to need a daylight and sunlight report where:
- a two-storey or rear extension in a tight-knit street in Arnold or Carlton could overshadow a neighbour's windows or garden;
- an infill or backland plot sits close to existing dwellings;
- a flatted or terraced scheme needs to show its own units receive adequate daylight; or
- a neighbour or case officer raises loss of light as an objection under Policy LPD 32.
Although Gedling's validation requirements do not automatically demand a daylight study for every application, providing one proactively can address amenity concerns before they become a reason for refusal.
