Planning Permission in Swale
Non-Metropolitan District in South East · Last updated April 2026
Swale borough stretches across north Kent from the marshes of the Isle of Sheppey to the fruit-growing countryside around Faversham and the edge of the Kent Downs AONB. The borough includes Sittingbourne, Sheerness, and the historic Cinque Port of Faversham, with extensive rural areas and coastal marshland. The varied landscape creates contrasting planning environments across the district.

The council approved 89.5% of applications in the year ending September 2025, processing decisions efficiently across the borough.
This guide covers permitted development rights, planning fees, and the application process for homeowners across Swale — from Victorian terraces in Sittingbourne to medieval timber-framed houses in Faversham and coastal properties on the Isle of Sheppey.

Permitted development in Swale
Swale's planning context varies significantly across the borough. Faversham's extensive conservation area and Article 4 directions restrict PD rights for much of the historic town. The Kent Downs AONB to the south reduces PD limits for extensions. The Isle of Sheppey and Sittingbourne's urban areas have standard PD rights in most locations. The 22 Article 4 directions focus on Faversham and other sensitive historic areas, removing rights for front-facing alterations and sometimes rear extensions. Properties outside protected zones enjoy normal permitted development rights.

Their 8-week performance of 95.3% is above the national average of 93%, which suggests LDC applications are likely to be processed on time.

- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
