Understanding the daylight requirements in Wealden is an increasingly important part of getting a planning application right across this large East Sussex district. Wealden stretches from the High Weald and the edge of the Ashdown Forest down towards the South Downs, taking in market towns such as Hailsham, Crowborough, Heathfield, Uckfield and Polegate. Whether you are extending a house in a tightly knit Crowborough street, building new homes on the edge of Hailsham, or converting a building close to a sensitive heritage setting, the way your scheme affects daylight and sunlight to neighbouring properties (and the daylight it provides to its own occupants) can make or break a decision.
This article sets out how Wealden District Council approaches daylight and sunlight, which local policies and guidance documents apply, and how a professional assessment to the recognised national standards can support your proposal.
The planning framework: who decides in Wealden
For most of the district, Wealden District Council is the local planning authority (LPA). East Sussex County Council is not the LPA for ordinary householder and residential development; its planning role is limited to matters such as minerals, waste and county council development. It is also worth noting that part of Wealden falls within the South Downs National Park, where the South Downs National Park Authority is the relevant planning authority. If your site is within the National Park boundary, you should check which body determines your application before you begin.
The statutory development plan for the Wealden District Council area is made up of:
- the Wealden District Core Strategy Local Plan, adopted in February 2013;
- the saved policies of the Wealden Local Plan 1998; and
- the Affordable Housing Delivery Local Plan (2016).
The council is also progressing an emerging new Local Plan through the statutory consultation stages, so applicants should always confirm the current adopted position at the point of applying.
Local Plan policies on amenity and design
Wealden does not set out a single numerical daylight or sunlight metric in its Local Plan. Instead, the protection of light, outlook and amenity is handled through broader design and amenity policies, of which the most directly relevant is the saved Wealden Local Plan 1998 Policy EN27 (Design). This policy requires that the scale, form, site coverage, density and design of development, together with the use of materials and landscaping, respect the character of adjoining development and, where appropriate, promote local distinctiveness. Critically for daylight matters, it also requires that development should not create an unacceptable adverse impact on the privacy and amenities of neighbouring occupiers — and the loss of daylight, sunlight and outlook is a core component of residential amenity.
This sits alongside the Core Strategy Local Plan (2013), which establishes the spatial strategy and the council's overarching commitment to high-quality, sustainable development. The Core Strategy includes Policy WCS 14 dealing with the principles of sustainable development across the district, and provides the strategic context within which detailed amenity considerations are weighed. Together these policies give planning officers the basis to refuse, or seek the amendment of, schemes that would unacceptably overshadow neighbours, block sunlight to gardens, or create an oppressive or enclosing effect.
The Wealden Design Guide SPD
Wealden has adopted the Wealden Design Guide as a Supplementary Planning Document (SPD). The council confirms that the guidance “represents an important material consideration in the determination of planning applications”. The Design Guide encourages a higher standard of design across the district, with attention to local landscape and building materials. While the Design Guide is concerned principally with character and design quality rather than prescribing numerical daylight targets, it reinforces the expectation that new development respects the amenity of existing residents — including reasonable access to light.
Is a daylight and sunlight report required in Wealden?
Wealden publishes a Validation Local List (most recently updated in October 2025) setting out the information needed to validate a planning application, alongside the mandatory national requirements. As with most district councils, Wealden does not demand a daylight and sunlight report on every application. However, where a proposal could reasonably affect the daylight or sunlight enjoyed by neighbouring properties — for example a two-storey extension close to a boundary, a backland development, a flatted scheme, or a taller building in a town-centre location — officers can and do request a daylight and sunlight assessment to demonstrate compliance with amenity policy.
Because the Local Plan does not contain its own numerical standard, the assessment of daylight and sunlight in Wealden is carried out against the recognised national technical guidance:
- BRE BR 209 (2022) — Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice, the standard reference used by planning authorities across England, including the Vertical Sky Component (VSC), No Sky Line / daylight distribution, and Annual Probable Sunlight Hours (APSH) tests;
- BS EN 17037 — the British and European standard on daylight provision within buildings; and
- the National Planning Policy Framework (NPPF), which directs that planning should secure a high standard of amenity for existing and future occupiers.
In short, these national standards apply through the Wealden Local Plan's amenity and design policies. A well-prepared report measures a scheme against BR 209 and BS EN 17037 and then relates the findings back to saved Policy EN27 and the Core Strategy, giving the case officer the evidence they need.
Local factors that affect daylight in Wealden
Two characteristics of the district are particularly relevant when thinking about daylight and sunlight:
- Constrained and protected landscapes. Large parts of Wealden lie within the High Weald National Landscape (formerly AONB) and close to the Ashdown Forest and the South Downs National Park. In these sensitive settings, schemes are scrutinised closely on design, massing and amenity, and a robust daylight/sunlight position can help demonstrate that a proposal sits comfortably within its surroundings.
- Mixed town and rural grain. The compact, often historic centres of Crowborough, Hailsham, Uckfield and Heathfield mean that infill and extensions frequently sit close to neighbouring dwellings, where loss of light and overshadowing of gardens are common grounds for objection. Demonstrating compliance with BRE BR 209 early can avoid costly redesign or refusal.
