Daylight requirements in Sandwell sit at the heart of how the borough judges new homes, extensions and taller buildings. Whether you are adding a rear extension in Bearwood, converting a commercial unit in Smethwick, or bringing forward a residential block in West Bromwich town centre, planning officers will expect new development to protect the daylight and sunlight enjoyed by neighbours and to provide acceptable internal conditions for future occupiers. This guide explains how Sandwell Metropolitan Borough Council assesses these matters, which policies and guidance apply, and how a competent assessment can support your application.
Who sets the rules in Sandwell
Sandwell Metropolitan Borough Council is the local planning authority for the six towns of West Bromwich, Smethwick, Oldbury, Rowley Regis, Tipton and Wednesbury. As one of the four Black Country authorities, Sandwell shares a strategic development plan with Dudley, Walsall and Wolverhampton.
The adopted development plan for the borough is currently:
- the Black Country Core Strategy (adopted February 2011, covering the period 2006–2026); and
- the saved Sandwell Site Allocations and Delivery (SAD) Development Plan Document together with adopted Area Action Plans.
A new Sandwell Local Plan is well advanced. It was submitted to the Secretary of State for independent examination on 11 December 2024, with public hearing sessions held during 2025. At the time of writing it has not been adopted, so the Black Country Core Strategy and saved Sandwell policies remain the starting point for decisions, while the emerging Local Plan carries growing weight as a material consideration as it progresses through examination.
The policies that govern daylight and amenity
Sandwell does not rely on a single “daylight policy”. Instead, daylight, sunlight, overshadowing and privacy are treated as part of a wider duty to protect residential amenity and to deliver good design. The most relevant adopted policies are:
- Policy ENV3 (Design Quality) of the Black Country Core Strategy, which requires development to achieve high standards of design and to respond to local character and the amenity of neighbouring uses.
- Policy CSP4 (Place-Making), which sets the overarching expectation that new development creates attractive, safe and high-quality places.
These strategic policies are applied alongside the saved Sandwell development management policies and, where relevant, the design expectations being carried through into the emerging Sandwell Local Plan. The consistent thread is that a scheme should not cause unacceptable harm to the living conditions of existing or future residents — and loss of daylight or sunlight is one of the clearest forms that harm can take.
The Residential Design Guide SPD
Sandwell’s most detailed local guidance is the Supplementary Planning Guidance on Residential Design (Residential Design Guide SPD, 2014). It provides design guidance for new residential development, including the relationship between buildings, separation distances, overlooking and the amenity of neighbours. Householder and residential proposals are routinely assessed against this guidance, so it is well worth reviewing before finalising a layout.
How BRE guidance fits in
Like most English authorities, Sandwell does not set its own numerical daylight and sunlight targets. Where a quantified assessment is needed, officers look to the recognised national methodology:
- BRE BR 209 – Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice (2022 edition), which provides the Vertical Sky Component, daylight distribution, Annual Probable Sunlight Hours and overshadowing tests used to judge impact on neighbours;
- BS EN 17037 (Daylight in Buildings), used to assess daylight provision for the occupiers of the new development itself; and
- the National Planning Policy Framework (NPPF), which requires good standards of amenity and supports the efficient use of land.
In short: the local plan creates the duty to protect amenity, and the BRE methodology is the technical yardstick used to demonstrate whether that duty has been met.
Local factors that affect daylight assessments in Sandwell
Sandwell is a densely developed metropolitan borough with a tight-grained mix of Victorian and Edwardian terraces, inter-war estates and post-war housing. Several local characteristics influence how daylight and sunlight issues arise:
- Conservation areas and Article 4 controls. Sandwell has a number of designated conservation areas, including the High Street, West Bromwich Conservation Area and the High Street and Crocketts Lane, Smethwick Conservation Area, where Article 4 Directions remove certain permitted development rights. In these areas, even modest extensions need planning permission and are scrutinised for their effect on neighbouring amenity and on the character of the area.
- Town-centre regeneration and densification. Sandwell is delivering an ambitious six-towns regeneration programme, supported by the Government’s Towns Fund in West Bromwich, Smethwick and Rowley Regis. Taller, denser residential schemes on town-centre and former industrial sites place daylight and sunlight squarely in the spotlight, both for neighbouring properties and for future occupiers of the new homes.
- Tight back-to-back terraced layouts. Much of the borough’s housing stock sits on compact plots with short rear gardens. Rear and two-storey side extensions can quickly trigger concerns about overshadowing and loss of light to adjoining windows, which is exactly where a BRE-based assessment helps.
When you are likely to need a daylight and sunlight report
A formal report is not required for every application, but it is commonly expected or advisable where:
- a proposal is two or more storeys and sits close to a neighbouring habitable-room window;
- a scheme increases height or massing on a constrained town-centre or backland site;
- an officer, neighbour objection or pre-application response raises loss of light; or
- the development creates a number of new dwellings whose own internal daylight needs to be demonstrated under BS EN 17037.
Submitting a clear, BRE-compliant assessment up front can prevent delays, focus negotiations on the real issues, and reduce the risk of refusal on amenity grounds. It is always sensible to check the council’s current validation checklist for the documents required for your particular application.
