Anyone planning a home extension, an infill plot or a larger residential scheme in Grimsby, Cleethorpes, Immingham or the surrounding villages needs to understand the daylight requirements in North East Lincolnshire. North East Lincolnshire Council is a unitary authority, so it acts as the single Local Planning Authority for the whole borough. This article sets out how the Council assesses the impact of development on daylight and sunlight, which adopted policies apply, and how the recognised technical standards fit in.
Daylight requirements in North East Lincolnshire: the policy framework
The statutory development plan is the North East Lincolnshire Local Plan 2013–2032, which the Council adopted on 22 March 2018 following an examination by an independent Planning Inspector. The Local Plan sets out the borough's vision and strategy to 2032, allocates land for housing, employment and retail, and provides the policy criteria against which planning applications are decided. It plans for the delivery of up to 13,340 new homes over the plan period. A review of the Local Plan is under way, but the 2018 plan remains the adopted document used for decisions today.
Daylight and sunlight are treated mainly as matters of residential amenity and good design. The most relevant policies are:
- Policy 22 – the design policy. Policy 22 seeks good design in all new development and is routinely applied to protect the amenity of neighbouring occupiers, including from loss of daylight and sunlight, overshadowing, overlooking and loss of privacy.
- Policy 5 – which, alongside Policy 22, supports good design across the borough and frames how development should relate to its surroundings and to neighbouring uses.
Together, Policies 5 and 22 of the Local Plan seek good design in all new developments, and the Council weighs the effect of a proposal on the daylight and sunlight enjoyed by adjoining homes when it determines applications.
Is there a specific daylight and sunlight standard for North East Lincolnshire?
North East Lincolnshire does not publish a bespoke numerical daylight and sunlight standard in its adopted Local Plan. There is no separate council metric setting out, for example, Vertical Sky Component thresholds or No Sky Line targets. Instead, daylight and sunlight are assessed through the design and amenity policies above, supported by the recognised national technical benchmarks:
- The Building Research Establishment guidance BR 209, Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice (2022 edition) – the established methodology for assessing loss of light to existing neighbours and the daylight available within new homes.
- BS EN 17037 Daylight in Buildings – the British and European standard for daylight provision in habitable rooms.
- The National Planning Policy Framework (NPPF), which requires new development to secure a good standard of amenity for existing and future occupiers.
Because the Local Plan does not set its own figures, these national documents effectively supply the technical detail when the Council applies Policy 22. For larger or more sensitive proposals, or where a development is close to existing dwellings, the Council's validation and consultation process may expect a daylight, sunlight and overshadowing assessment to be submitted so that officers can judge the impact against BRE methodology.
Local factors that affect daylight in North East Lincolnshire
The borough has a distinctive geography and built character that shapes daylight and sunlight considerations:
- The Grimsby and Cleethorpes coast. The two towns front the Humber estuary, and Cleethorpes in particular has a popular seafront. Coastal and seafront sites raise specific questions about overshadowing of public spaces and the orientation of new homes to capture sunlight, as well as protecting the outlook and amenity of established terraces.
- The port and docks. Grimsby is defined by its historic docks and the Grade I listed Dock Tower, and the wider area around the Humber ports remains a major focus for regeneration and employment-led development. Mixed-use and higher-density redevelopment in and around the dock estate can bring taller buildings closer together, making daylight and sunlight between facing facades a material consideration.
- Established residential terraces. Much of Grimsby and Cleethorpes comprises tightly knit terraced and semi-detached streets, where rear extensions and outbuildings can readily affect a neighbour's daylight, sunlight and rear-garden amenity – exactly the situations Policy 22 is used to control.
What this means for your project
Whether you are extending a terraced home in central Grimsby, building near the Cleethorpes seafront, or bringing forward a development on a regeneration site, the Council will expect you to show that neighbouring properties keep acceptable daylight and sunlight and that new homes are themselves well lit. A clear, BRE-based daylight and sunlight assessment helps officers reach a positive recommendation and reassures neighbours that impacts have been properly tested. It pays to commission this analysis early, while the design can still be adjusted in height, depth or position without difficulty.
