Understanding the daylight requirements in East Lindsey is essential for anyone planning a house extension, an infill plot or a larger residential scheme in this part of Lincolnshire. East Lindsey District Council is the local planning authority (LPA) for the area — not Lincolnshire County Council — and it determines applications across a large rural district that stretches from the seaside resorts of Skegness, Mablethorpe and Chapel St Leonards to the market town of Louth and the Lincolnshire Wolds. This article explains how the council expects daylight and sunlight to be considered, which adopted policies apply, and what you need to submit to get an application validated.
Who decides planning applications in East Lindsey?
East Lindsey is a shire district. That means the district council, based at The Hub in Horncastle, is the body that grants or refuses planning permission for householder and residential development. The county council deals with matters such as highways, education and minerals and waste, but it is the district that assesses whether your proposal protects the daylight, sunlight and general amenity of neighbouring homes. If your scheme could overshadow a neighbour's garden or block light to their windows, it is East Lindsey's planners who will weigh that impact.
The adopted Local Plan and the policies that matter
The development plan for the area is the East Lindsey Local Plan, whose Core Strategy was adopted in July 2018, sitting alongside the Settlement Proposals Development Plan Document. There is no separate numerical daylight standard written into the plan, so amenity and design are judged through the criteria-based policies below.
- Strategic Policy 10 (SP10) – Design. This is the principal design and amenity policy. It supports well-designed development where the “layout, scale, massing, height and density reflect the character of the surrounding area”, and it expressly protects “nearby residential amenity”. Notably for a rural coastal and Wolds district, SP10 also asks that development “minimise glare and light spillage” and not harm the “rural or dark-sky character” of a settlement or landscape — a reminder that light, both natural and artificial, is taken seriously here.
- The place-making checklist that accompanies SP10 asks applicants to demonstrate, among other things, “architectural quality” and how a building “relate[s] to its surroundings”, which in practice covers the relationship between new and existing buildings, including separation distances and overlooking.
- Strategic Policy 27 (SP27) – Renewable and Low Carbon Energy lists “residential amenity” first among the matters against which impacts are weighed, illustrating that the protection of living conditions runs throughout the plan, not just in the design policy.
Because the Local Plan sets no fixed daylight figures, the council relies on national methodology. In practice this means the Building Research Establishment's guidance — BRE BR 209, “Site layout planning for daylight and sunlight: a guide to good practice” (third edition, 2022) — together with the daylight provisions of BS EN 17037 and the amenity expectations of the National Planning Policy Framework (NPPF), applied through SP10 and the wider Local Plan.
Is a Sunlight/Daylight Assessment required in East Lindsey?
Yes — East Lindsey District Council includes a Sunlight/Daylight Assessment in its list of supporting documents that may be required to validate a planning application, alongside items such as a Design and Access Statement. Where a proposal could reasonably affect light to neighbouring properties — for example a two-storey extension close to a boundary, a backland plot or a taller building near existing homes — submitting a BRE-based assessment up front avoids the application being held up at validation or refused for lack of information.
The council does not publish its own numerical daylight Supplementary Planning Document. Older county-wide design references such as the Lincolnshire Residential Design Guide are acknowledged in the Local Plan as containing good design principles, but the technical benchmarks used to judge daylight and sunlight are those in BRE BR 209 (2022).
What a BRE-based assessment typically covers
A robust Sunlight/Daylight Assessment for an East Lindsey application will usually report against the standard BRE measures:
- Vertical Sky Component (VSC) at neighbouring windows, with the 27% target and the “no worse than 0.8 times the former value” test.
- No Sky Line / daylight distribution within affected rooms.
- Annual Probable Sunlight Hours (APSH) for windows with a southerly aspect and sunlight to gardens and amenity areas.
- Overshadowing of neighbouring gardens and open space, often shown with shadow diagrams across the year.
For new homes, the daylight and sunlight standards of BS EN 17037 can also be used to demonstrate that the proposed rooms themselves will be adequately lit.
Local context that affects daylight in East Lindsey
Two genuinely local factors shape how schemes come forward:
- The coastal resorts. In Skegness, Mablethorpe and Chapel St Leonards the grain is often tight, with terraced streets, holiday accommodation and flatted conversions set close together. Proposals to add storeys or convert buildings near the seafront frequently raise overshadowing and overlooking issues for closely spaced neighbours, which is exactly where a VSC and APSH assessment helps.
- The Lincolnshire Wolds. A large part of the district lies within or near the Lincolnshire Wolds Area of Outstanding Natural Beauty, where SP10's emphasis on the “rural or dark-sky character” means light spill and the visual relationship between buildings are scrutinised closely, particularly in and around villages such as Tetford and Tealby.
In the historic core of Louth, the tight medieval street pattern and the many listed buildings mean that even modest extensions can have a real effect on a neighbour's light, so an early appraisal is sensible.
