Planning Permission in Thanet
Non-Metropolitan District in South East · Last updated April 2026
Thanet is the most easterly district in Kent, an island-like peninsula bordered by the sea on three sides. The district includes the seaside towns of Margate, Broadstairs, and Ramsgate — each with a distinct character shaped by their maritime heritage. Margate's creative regeneration, anchored by the Turner Contemporary gallery, has transformed the town's prospects, while Ramsgate's Regency harbour and Broadstairs' Dickensian character draw visitors and new residents.
With 27 conservation areas and 1,051 listed buildings, Thanet's heritage is primarily coastal and Georgian/Victorian in character. The council approved 87% of applications in the year ending September 2025, processing decisions across the three main towns and surrounding rural parishes.
This guide covers permitted development rights, planning fees, and the application process for homeowners across Thanet — from Victorian terraces in Margate to Regency villas in Ramsgate and seaside cottages in Broadstairs.

Permitted development in Thanet
Thanet's planning context is shaped by its coastal setting and the heritage character of its three main towns. The 27 conservation areas cover significant portions of Margate, Broadstairs, and Ramsgate, restricting permitted development rights for many properties. Margate's Old Town, Ramsgate's Regency harbour, and Broadstairs' seafront all have conservation area designations. Outside these protected zones, standard PD rights apply. The district has no Green Belt and no AONB, so properties outside conservation areas generally enjoy full permitted development rights.
What Thanet expects from your project
Local Plan: Thanet Local Plan 2011–2031
Thanet District adopted its Local Plan in July 2020 following a difficult examination. The plan provides for over 17,000 new homes including major new housing on the former Manston Airport site and in Birchington, Westgate and Broadstairs. The district's coastal location and special character required careful balancing of growth and conservation.
Emerging / replacement plan
Thanet is monitoring the Local Plan and will begin a formal review in line with national requirements, expected to start around 2025–2026.
27 conservation areas
Thanet 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.
Conservation areas in Thanet
27 designated conservation areas
Thanet's 27 conservation areas protect the architectural character of the three seaside towns and surrounding villages. Ramsgate's conservation area is one of the largest in Kent, encompassing the Regency harbour, the Royal Harbour, and surrounding Georgian and Victorian streets. Margate's Old Town and seafront conservation areas capture the town's historic core. Broadstairs' conservation area includes the famous Viking Bay and surrounding Dickensian streetscape. With 1,051 listed buildings, the council carefully assesses proposals affecting the distinctive coastal architecture.

Planning application statistics
Year ending September 2025 | Source: MHCLG planning application statistics
Thanet received 790 planning applications and decided 779 in the year ending September 2025. The approval rate of 87% 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.
Thanet processed planning decisions with an 87% approval rate in the year ending September 2025. This rate is close to the national average and reflects the council's balanced approach to development. The three main towns generate the majority of applications, with heritage considerations applying to a significant proportion due to the extensive conservation area coverage. Processing efficiency is good across all categories.
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 Thanet
Housing Delivery Test 2023 measurement | Source: MHCLG
Thanet delivered 1,801 homes against a requirement of 2,668 over the three-year measurement period, giving a Housing Delivery Test score of 67%. This is well below the 75% threshold, which triggers the most significant consequence: the “presumption in favour of sustainable development” (also called the “tilted balance”). This means planning applications for housing should be approved unless the harm would significantly and demonstrably outweigh the benefits. For homeowners, this is a strong signal — Thanet is under considerable pressure to approve housing, making it one of the more favourable environments for residential planning applications in England.
Lawful Development Certificates in Thanet
A Lawful Development Certificate (LDC) is formal confirmation from Thanet 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.
Thanet decided 328 householder applications in the year ending september 2025. Their 8-week performance of 84.8% 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 Thanet
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Thanet'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
Thanet 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.
