Anstey Horne is a leading provider of Daylight and Sunlight Assessments in Manchester, offering expert advice to developers, planners, architects, and consultants across Greater Manchester and the North West.

Our reports help secure planning permission, mitigate risk, and demonstrate compliance with national and local guidelines.

A Daylight and Sunlight Assessment examines the impact of a new development on the natural light levels of both existing and proposed buildings. These assessments form a critical part of the planning process in Manchester, especially in high-density and mixed-use areas.

Using precise calculations and 3D modelling, we assess how a scheme will affect access to daylight, sunlight, and overshadowing in accordance with industry standards.

Why Are Daylight and Sunlight Assessments Crucial in Manchester?

Manchester's urban fabric includes dense city-centre plots, sensitive conservation areas, and rapidly growing regeneration zones. These conditions make it essential to carefully evaluate and protect daylight and sunlight access for both new and existing occupiers.

A well-prepared Daylight and Sunlight Assessment Manchester can:

Demonstrate adherence to BRE Guidelines (BR209, 2022)

Support planning applications with credible technical evidence

Address concerns raised by Manchester City Council and local consultees

Help prevent objections, refusals, or delays

Safeguard neighbouring amenity and avoid right to light disputes

All our assessments are fully compliant with the latest edition of <a href="https://bregroup.com/store/bookshop/site-layout-planning-for-daylight-and-sunlight-a-guide-to-good-practice-br-209-2022-edition" target="_blank" rel="noreferrer noopener">Site Layout Planning for Daylight and Sunlight – A Guide to Good Practice (BR209)</a> and the British Standard BS EN 17037. Each report typically includes:

<a href="https://www.ansteyhorne.co.uk/news/vertical-sky-component-vsc">Vertical Sky Component (VSC)</a> – Measures skylight reaching existing windows

<a href="https://www.ansteyhorne.co.uk/news/no-sky-line">No Sky Line (NSL)</a> – Assesses the distribution of daylight within rooms

<a href="https://www.ansteyhorne.co.uk/news/annual-probable-sunlight-hours-apsh">Annual Probable Sunlight Hours (APSH)</a> – Evaluates sunlight received at specific windows

Overshadowing – Reviews the impact on gardens, terraces, and communal outdoor areas

<a href="https://www.ansteyhorne.co.uk/news/annual-probable-sunlight-hours-apsh">Solar PV Impact Assessments</a> – Ensures solar panels are not compromised by development

We use advanced 3D software to simulate real-world lighting conditions and provide robust evidence suitable for submission to planning officers, committees, and appeal inspectors.

A Daylight and Sunlight Assessment is typically required in Manchester when:

A proposed development is close to neighbouring dwellings

There are concerns about overshadowing of gardens, balconies, or amenity space

The local authority requests it as part of a planning application

The proposal may breach privacy, overshadow adjacent plots, or reduce natural light

Our Manchester team has worked with developers, housebuilders, and planning consultants on major schemes across the city and wider region.

We are nationally recognised experts in daylight and sunlight analysis. Our Manchester-based consultants offer:

Deep knowledge of local planning policies and urban design

Support with appeals, expert witness services, and planning negotiations

From tower schemes in the city centre to residential masterplans in the suburbs, we tailor our approach to fit your project’s size, complexity, and planning stage.
