Planning Permission in Mid Devon
Non-Metropolitan District in South West · Last updated April 2026
Mid Devon is a rural district in the heart of Devon, centred on the market towns of Tiverton, Cullompton, and Crediton. With 51 conservation areas, no Article 4 directions, and 2,574 listed buildings, the district has a deeply rural character with an exceptionally rich built heritage of farmhouses, cob cottages, and medieval churches.
The council processes around 716 applications annually with a 93.6% approval rate — one of the highest in Devon. Mid Devon's planning landscape is defined by its rolling countryside, traditional farming settlements, and the need to balance rural housing needs with heritage protection.
Homeowners should consult the Mid Devon Local Plan Review for guidance. The density of conservation areas and listed buildings across the district means checking designations is essential before starting any work.

Permitted development in Mid Devon
Mid Devon has 51 conservation areas but no Article 4 directions and no Green Belt, meaning that standard permitted development rights apply to most properties outside conservation areas. However, the high density of listed buildings (2,574) across a relatively small rural district means that many properties are either listed or within the curtilage of listed buildings. In the Blackdown Hills AONB (covering the eastern part of the district), landscape impact is also a consideration for planning applications.
What Mid Devon expects from your project
Local Plan: Mid Devon Local Plan 2013–2033
Mid Devon District adopted its Local Plan in December 2015. The rural district is centred on Tiverton, Cullompton and Crediton. The plan provides for around 6,000 new homes over the plan period, with a strategic allocation at Cullompton urban extension (Junction 28 M5) and a science and technology park at Tiverton.
Emerging / replacement plan
Mid Devon is preparing a new Local Plan. Regulation 18 consultation ran in 2022 and the council is working toward a Regulation 19 Pre-Submission plan in 2025.
51 conservation areas
Mid Devon has a high number of conservation areas. Check whether your property falls within one before starting any work — conservation area status significantly restricts what you can do without planning permission.
93.6% approval rate
Mid Devon approves 93.6% of planning applications, above the national average of 86.9%. Well-designed residential applications in this area tend to have a good chance of success.
Conservation areas in Mid Devon
51 designated conservation areas
The 51 conservation areas in Mid Devon protect the character of virtually every settlement in the district, from the market town centres of Tiverton, Cullompton, and Crediton to dozens of small rural villages and hamlets. The district's distinctive Devon vernacular — cob walls, thatched roofs, red sandstone, and limewashed render — is a key element of conservation area character. Properties within these areas face restrictions on extensions, dormers, and external alterations.

Listed buildings in Mid Devon
There are 2,574 listed buildings in Mid Devon. If your property is listed, permitted development rights are significantly restricted. Most external and many internal alterations will require listed building consent, which is separate from planning permission. Always check with Mid Devon's conservation team before starting any work on a listed property.

Mid Devon District Council received 716 planning applications in the year ending September 2025, with a 93.6% approval rate across 671 decisions. The council processed 212 householder applications. The high approval rate reflects the district's supportive approach to appropriate development and the effectiveness of pre-application engagement. The council operates with a high delegation rate.
If your project complies with permitted development rules, you don't need to worry about approval rates — a Lawful Development Certificate is a factual assessment, not a judgment call.

Housing delivery in Mid Devon
Housing Delivery Test 2023 measurement | Source: MHCLG
Mid Devon delivered 828 homes against a requirement of 967 over the three-year measurement period, giving a Housing Delivery Test score of 86%. This is below the 95% threshold, which means Mid Devon must publish an action plan setting out how it intends to increase housing delivery. For homeowners, this is a positive signal — the council is under pressure to approve more housing, which can make planning officers more receptive to well-designed residential applications and extensions that add living space.
Lawful Development Certificates in Mid Devon
A Lawful Development Certificate (LDC) is formal confirmation from Mid Devon 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.
Mid Devon decided 212 householder applications in the year ending september 2025. Their 8-week performance of 99.5% is above the national average of 93%, which suggests LDC applications are likely to be processed on time. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Mid Devon
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Mid Devon's website. 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
Mid Devon 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.
