Planning Permission in Cumberland
Unitary Authority in North West · Last updated April 2026
Cumberland is a unitary authority formed in 2023, covering the western part of the former Cumbria county including Carlisle, Allerdale, and Copeland. With 51 conservation areas, no Article 4 directions, and 2,309 listed buildings, the authority stretches from the Scottish border to the West Cumbrian coast, with parts bordering the Lake District National Park.
The council handles around 1,310 applications annually with a 97.4% approval rate — one of the highest in England. The planning landscape combines the historic city of Carlisle with the rural communities of the Solway coast, the West Cumbrian towns of Workington and Whitehaven, and the nuclear industry around Sellafield.
Homeowners should consult the local plan for guidance. Properties near the Lake District boundary should check whether the National Park Authority handles their planning.

Permitted development in Cumberland
Cumberland has 51 conservation areas but no Article 4 directions and no Green Belt, meaning standard PD rights apply to most properties outside conservation areas. The 2,309 listed buildings are the main additional constraint. The authority has one of the most permissive PD landscapes in England, reflected in its exceptionally high 97.4% approval rate. Properties near the Lake District boundary should check whether they fall within the National Park.
What Cumberland expects from your project
Local Plan: Cumberland Local Plan
Cumberland Council was created in April 2023, merging Allerdale, Carlisle City and Copeland districts. Saved policies from those legacy plans continue to apply within their respective areas. The new unitary area has significant coastal, Lake District fringe and urban characteristics.
Emerging / replacement plan
Cumberland is preparing a new unitary Local Plan. A Regulation 18 Issues and Options consultation commenced in 2024, with the full plan preparation expected to run through 2025-2027.
51 conservation areas
Cumberland 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.
97.4% approval rate
Cumberland approves 97.4% 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 Cumberland
51 designated conservation areas
The 51 conservation areas protect Cumberland's most important historic environments — from the medieval walled city of Carlisle with its castle and cathedral to the Georgian port of Whitehaven, the fishing villages of the Solway coast, and the historic market towns of Cockermouth and Penrith. The area's building traditions include red sandstone in Carlisle and the Eden Valley, slate in the west, and local stone in rural areas.
Article 4 directions in Cumberland

Listed buildings in Cumberland
There are 2,309 listed buildings in Cumberland. 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 Cumberland's conservation team before starting any work on a listed property.

Lawful Development Certificates in Cumberland
A Lawful Development Certificate (LDC) is formal confirmation from Cumberland 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.
Cumberland decided 445 householder applications in the year ending september 2025. Their 8-week performance of 80.7% 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 Cumberland
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Cumberland'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
Cumberland 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.
