Planning Permission in South Somerset
Local Planning Authority in England · Last updated April 2026
South Somerset was replaced by Somerset in 2023 as part of local government reorganisation. Planning applications in this area are now handled by Somerset.
View Somerset planning authority pageSouth Somerset is a district local planning authority covering a large swathe of south-west Somerset, encompassing market towns like Yeovil, Crewkerne, and Langport, alongside numerous villages and rural settlements. The area is characterised by mixed urban and countryside landscapes, with strong agricultural heritage and a growing economy centred around light industry and services.
As the planning authority for the district, South Somerset determines all planning applications within its boundaries, from householder extensions to major commercial developments. The area has no designated green belt, which generally means fewer blanket restrictions on development compared to protected green belt areas elsewhere in England. However, this does not mean building work is unrestricted—all proposals must still comply with the Local Plan and other planning policies.
For homeowners considering building work, understanding your rights under permitted development rules and when you need formal planning permission is essential. South Somerset's planning policies aim to support sustainable growth while protecting local character and amenity. Early engagement with the council through pre-application advice can save time and expense before submitting a formal application.

Permitted development in South Somerset
Permitted development rights in South Somerset allow homeowners to carry out certain building works without applying for planning permission, provided specific conditions and limits are met. These include many domestic extensions, loft conversions, garden buildings, and alterations. However, South Somerset has not designated any Article 4 Direction areas that would restrict these rights, meaning permitted development thresholds apply consistently across the district. That said, listed buildings, properties in conservation areas (though South Somerset has none), or those subject to conditions are exceptions. Always check the specific circumstances of your property before assuming work is permitted—factors like proximity to boundaries, floor area limits, and materials can affect whether permission is needed. The council's planning team can confirm your entitlements through a lawfulness enquiry if you are uncertain.
Local Plan: South Somerset District Local Plan 2006–2028
South Somerset District Council adopted its Local Plan in April 2015. The rural district centred on Yeovil and Chard was dissolved in April 2023 and merged with three other Somerset districts into the new Somerset Council. The plan had supported significant growth at Yeovil and a network of rural service centres.
Emerging / replacement plan
Somerset Council (formed April 2023) is preparing a new Local Plan covering the whole county. Regulation 18 consultation is anticipated in 2025–2026.

Lawful Development Certificates in South Somerset
A Lawful Development Certificate (LDC) is formal confirmation from South Somerset that your project is lawful under permitted development rules. It is not legally required before you build, but it is the only official document that proves your project did not need planning permission. Most solicitors will ask for one when you come to sell, remortgage, or insure your property.
How to apply for an LDC in South Somerset
You can apply for a Lawful Development Certificate through the Planning Portal. You will need to submit:
- A completed application form (available on the Planning Portal)
- A site location plan at 1:1250 or 1:2500 scale
- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
- The application fee of £258
South Somerset must issue a decision within 8 weeks. If the application is approved, the certificate is a permanent legal record that the development is lawful. If refused, you can appeal to the Planning Inspectorate or amend your project and reapply.
