Daylight requirements in Armagh City, Banbridge and Craigavon are shaped by a distinctive planning position. Although the borough council has been the local planning authority since planning powers transferred to Northern Ireland's eleven councils on 1 April 2015, the council has not yet adopted its new Local Development Plan (LDP). That means daylight, sunlight and residential amenity are assessed against retained regional policy and the borough's legacy area plans, rather than a modern, locally adopted plan strategy. For anyone bringing forward a householder extension, infill dwelling or larger residential scheme across Armagh, Banbridge, Portadown, Lurgan or Craigavon, understanding which documents actually carry weight is the first step.
This article sets out how the policy framework operates in the borough, what the daylight and sunlight tests involve in practice, and where a specialist assessment to BRE BR 209 (2022) can support an application.
The Local Development Plan position in the borough
Armagh City, Banbridge and Craigavon Borough Council is preparing its Local Development Plan 2030 under the Planning Act (Northern Ireland) 2011. The plan is taken forward in two parts: a Plan Strategy followed by a Local Policies Plan. The borough published its Preferred Options Paper (POP) for public consultation, which ran from 28 March 2018 to 30 May 2018. The Preferred Options Paper is the first formal stage and is intended to inform the subsequent draft Plan Strategy.
Crucially, the Plan Strategy has not been adopted. The council's published timetable has been under review pending agreement with the Department for Infrastructure. Until the Plan Strategy is adopted, the borough's day-to-day development management continues to rely on a combination of retained regional policy and the older departmental area plans. The legal weight of an adopted plan was underlined in the Court of Appeal in McCann v Armagh City, Banbridge and Craigavon Borough Council, which reinforced the importance of strict compliance with the relevant development plan when determining applications.
The retained area plans covering the borough are the Craigavon Area Plan 2010, the Banbridge/Newry and Mourne Area Plan 2015 and the Armagh Area Plan 2018. These are read together with regional policy in a tiered manner, which the council itself describes: applicants should start with the relevant area plan, then the Strategic Planning Policy Statement, and finally the relevant Planning Policy Statement.
Daylight requirements in Armagh City, Banbridge and Craigavon: the policy tests
In the absence of an adopted Plan Strategy, two retained documents do most of the work on daylight, sunlight, overshadowing and overlooking:
- Strategic Planning Policy Statement for Northern Ireland (SPPS, 2015) — the overarching regional statement, which retains earlier Planning Policy Statements until they are superseded by an adopted LDP.
- Planning Policy Statement 7 (PPS 7) 'Quality Residential Environments', together with its Addendum on residential extensions and alterations and the companion design guide 'Creating Places'.
PPS 7 sets out the qualities expected of new housing, and Policy QD 1 requires that new residential development respects the amenity of neighbouring occupiers. The supporting guidance in 'Creating Places' is where the practical daylight, privacy and separation standards sit. As a general benchmark, a separation distance of no less than 20 metres is expected between directly facing windows of main habitable rooms (living rooms, bedrooms, dining rooms and kitchens) to protect privacy and avoid overlooking. Where a window faces a blank gable or a wall containing only non-habitable room windows, a reduced separation of no less than 10 metres may be acceptable.
These figures are not arbitrary. They exist partly to protect daylight and sunlight as well as privacy, and 'Creating Places' is explicit that in higher-density or inner-urban locations a lesser separation may be acceptable only where a thorough analysis of site characteristics — topography, orientation, sunlight and daylight levels and design — demonstrates no detrimental impact on amenity. In the historic Georgian core of Armagh, or in the tighter terraced streets of Portadown and Lurgan, that kind of justification is exactly where a technical daylight and sunlight assessment becomes valuable.
Where extensions and alterations are concerned
For householder proposals — a rear or two-storey extension, a loft conversion with new windows, or a garden building — the PPS 7 Addendum is the most directly relevant document. It addresses the impact of extensions on the daylight reaching neighbouring windows and gardens, overshadowing, and the loss of light to habitable rooms. A common cause of refusal or objection is an extension that breaches the angle of light to a neighbour's principal windows or that significantly overshadows an adjoining garden or patio.
How daylight and sunlight are assessed in practice
Northern Ireland's planning policy sets the amenity objectives, but it does not prescribe a single numerical daylight method. In practice the recognised technical benchmark is the Building Research Establishment guidance. A robust assessment will typically apply:
- BRE BR 209 (2022), Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice, which provides the established methods for testing impact on neighbouring properties and the quality of light within proposed dwellings.
- BS EN 17037 'Daylight in Buildings', the European standard for daylight provision now reflected in BR 209.
For impact on neighbours, the principal tests are the Vertical Sky Component (VSC) and the daylight distribution (no sky line) check for affected rooms, alongside the Annual Probable Sunlight Hours (APSH) test for sunlight to windows facing within 90 degrees of due south. For gardens and amenity spaces, the overshadowing test examines how much of the area receives at least two hours of sunlight on 21 March. Presenting these results clearly allows a case officer at the borough council to weigh a scheme against the amenity objectives in PPS 7 and 'Creating Places' with confidence.
Two local factors worth noting
- Craigavon's planned layout. Craigavon was developed as a 1960s new town with generous spacing, linear parks and segregated roads. Infill and densification proposals there are often judged against that established open character, where overshadowing and separation can be sensitive considerations.
- Armagh's historic city core. The cathedral city of Armagh, with its two St Patrick's cathedrals and Georgian Mall, contains tight historic streets and conservation interests, so daylight and overlooking analysis frequently has to reconcile amenity with heritage-led tighter forms of development.
How Fortress Associates can help
Fortress Associates provides our daylight and sunlight report service for householders, architects, developers and agents across the borough and the rest of the UK. Our reports are prepared to BRE BR 209 (2022) and BS EN 17037, and are written to address the amenity tests in the SPPS, PPS 7 and 'Creating Places' so they speak directly to the council's assessment. We work to a 4–5 working day turnaround and ask for no advance payment. We also prepare Building Regulations drawings under the Building Regulations (Northern Ireland). To discuss a proposal, see our services or contact us. If your project sits in a neighbouring authority, you may also find our guide to daylight requirements in Lisburn and Castlereagh useful.
