Planning Permission in North Kesteven
Non-Metropolitan District in East Midlands · Last updated April 2026
North Kesteven District Council covers a large rural district in central Lincolnshire, stretching from the outskirts of Lincoln southward to the Sleaford area. The district has 38 conservation areas and 1,005 listed buildings, reflecting its rich agricultural and architectural heritage. Planning decisions are guided by the Central Lincolnshire Local Plan adopted in April 2023, shared with Lincoln and West Lindsey, with a Community Infrastructure Levy (CIL) in place since January 2018.
North Kesteven is one of the most proactive districts for neighbourhood planning, with 12 made (adopted) neighbourhood plans giving local communities a direct say in shaping development in their areas. The district's housing delivery test score of 178% demonstrates strong housing delivery, well exceeding the required targets. Major growth is focused around the Sleaford South Quadrant (approximately 1,450 homes) and the North Hykeham Relief Road — a £180-208 million project that will unlock significant development land on the southern edge of Lincoln.
The district is also home to several RAF bases including Cranwell, Digby, and Waddington, which create specific planning considerations including aircraft noise zones and safeguarding areas. Three Article 4 directions in Heckington, Leasingham, and Wilsford conservation areas restrict permitted development rights to protect these historic village environments. The council offers both free basic pre-application advice and a detailed £109 householder service.

Permitted development in North Kesteven
Permitted development rights in North Kesteven follow national regulations, with additional restrictions applying in the district's 38 conservation areas. Three Article 4 directions in Heckington, Leasingham, and Wilsford conservation areas restrict alterations that would normally be permitted development, including changes to windows, doors, and boundary features. Properties near RAF bases may be subject to safeguarding zones that affect building heights and certain types of development. The council determines 98.3% of householder applications within the eight-week target — one of the highest rates in the country — and offers free basic pre-application advice to help homeowners understand what is permitted.
What North Kesteven expects from your project
North Kesteven's design context is predominantly rural, with building traditions varying across the district according to the underlying geology. The Lincoln Cliff and limestone belt produce distinctive stone-built villages, while the clay vale to the east is characterised by red brick and pantile construction. The Central Lincolnshire Local Plan includes comprehensive design policies requiring new development to respond to local character, materials, and settlement patterns. CIL charges apply to most new development. RAF safeguarding areas around Cranwell, Digby, and Waddington may affect building heights and the use of reflective materials. The council encourages sustainable design including renewable energy and electric vehicle charging.
Local Plan: North Kesteven Local Plan 2017–2036
North Kesteven adopted its Local Plan in February 2023 following a lengthy examination. The district covers the rural hinterland south of Lincoln and the A1 corridor. The plan provides for around 9,500 new homes and significant employment growth at Sleaford and the A17/A15 gateway corridors.
