Permitted development in Dover
Dover's planning context is heavily shaped by its extraordinary heritage density. With 103 conservation areas and 55 Article 4 directions, permitted development rights are restricted across a very large proportion of the district. The Kent Downs AONB covers significant inland areas, further reducing PD limits for extensions. Deal, Sandwich, and Dover town centre all have extensive Article 4 coverage removing rights for front-facing alterations. Even outside these zones, the council expects development to respect the district's distinctive coastal and rural character.
What Dover expects from your project
Local Plan: Dover District Core Strategy
Dover's development plan relies on saved policies from its Core Strategy adopted in 2010. The district is notable for its role as a major international gateway with the Port of Dover and Channel Tunnel, alongside significant regeneration opportunities in Dover town centre and the coastal towns of Deal and Sandwich.
Emerging / replacement plan
Dover is preparing a new Local Plan (Local Plan 2040). A Regulation 19 Pre-Submission consultation ran in 2023, with submission to the Planning Inspectorate anticipated in 2024–2025 and adoption targeted for 2026.
103 conservation areas
Dover 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.
55 Article 4 directions
Dover has applied Article 4 directions to 55 areas, which remove certain permitted development rights in those zones. Use our free checker to see if your property is affected.
Conservation areas in Dover
103 designated conservation areas
Dover's 103 conservation areas represent one of the highest concentrations in England. Deal's seafront and Georgian terraces, Sandwich's complete medieval street pattern (one of England's best-preserved), Walmer's coastal village, and Dover's castle precinct each form major designations. With 1,926 listed buildings and 55 Article 4 directions, the council's heritage assessment is rigorous. Many Article 4 directions cover changes to windows, doors, boundary walls, and roofing materials. Homeowners in these areas must check constraints carefully before assuming any work is permitted development.

Listed buildings in Dover
There are 1,926 listed buildings in Dover. If your property is listed, permitted development rights are significantly restricted.

Always check with Dover's conservation team before starting any work on a listed property.
Planning application statistics
Year ending September 2025 | Source: MHCLG planning application statistics
Dover received 805 planning applications and decided 822 in the year ending September 2025. The approval rate of 89.5% is above the national average of 86.9%. Major applications are expected to be decided within 13 weeks, while householder and other non-major applications have an 8-week target. The “in time” figures include decisions made within agreed extensions of time.
Dover processed 822 planning decisions from 805 applications received in the year ending September 2025. The 89.5% approval rate is solid given the district's extensive heritage constraints. Major applications achieved 87.1% on-time performance, minors 89.4%, and householder applications 91.1%. The 93.6% delegation rate reflects efficient processing despite the complex heritage environment.
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 Dover
Housing Delivery Test 2023 measurement | Source: MHCLG
Dover delivered 1,659 homes against a requirement of 1,565 over the three-year measurement period, giving a Housing Delivery Test score of 106%. This is above the 95% threshold, which means there are no government-imposed consequences for housing under-delivery.

Lawful Development Certificates in Dover
A Lawful Development Certificate (LDC) is formal confirmation from Dover 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.
Dover decided 415 householder applications in the year ending september 2025. Their 8-week performance of 91.1% is below the national average of 93%, so LDC applications may take longer than the 8-week target. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Dover
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Dover'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
Dover 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.
