Planning Permission and Cladding: Dorset Rules You Should Know
When it comes to improving or updating the exterior of your home or building, cladding is one of the most popular and transformative options available. It can completely change the appearance of a property, improve insulation, and increase its value. But before you start browsing cladding materials or calling installers, there’s one crucial question you need to answer: Do you need planning permission for home cladding in Dorset?
If you live in Dorset, it’s essential to understand the local planning rules, building regulations, and conservation area restrictions that might apply. Dorset is a county rich in heritage, natural beauty, and protected zones, which can influence what changes you’re allowed to make to your property’s exterior.
In this blog, we’ll break down everything you need to know about planning permission and cladding in Dorset, from general UK rules to local council considerations and practical advice to help you stay compliant.
What Is Cladding?
Cladding refers to the application of one material over another to provide a protective or decorative layer on a building's exterior. It comes in various forms, including:
-
uPVC cladding
-
Timber cladding
-
Stone or brick slips
-
Metal panels
-
Fibre cement boards
-
Composite cladding
Cladding in Dorset is popular for its durability, low maintenance, and ability to withstand the county’s diverse weather conditions—from salty coastal air to heavy inland rainfall.
When Do You Need Planning Permission for Cladding?
In general, you do not need planning permission to install cladding on a residential property if:
-
The property is not listed
-
It’s not located in a conservation area, National Park, or Area of Outstanding Natural Beauty (AONB)
-
You’re not significantly altering the height or footprint of the building
-
The materials used are in keeping with the existing look or local aesthetic
This is covered under Permitted Development Rights. However, these rights can be restricted or removed depending on your location and the type of property you own.
Let’s look at what this means specifically for Dorset.
Special Considerations for Cladding in Dorset
1. Conservation Areas
Dorset is home to dozens of designated conservation areas, including parts of towns like Bridport, Lyme Regis, Shaftesbury, Sherborne, and sections of Weymouth and Dorchester. If your home is in a conservation area, you will likely need planning permission for any cladding changes, even if the material is similar to what’s already in place.
Local planning authorities are strict about maintaining the historical or architectural character of these areas. Adding modern cladding to a Georgian or Victorian home, for example, might be denied unless it’s historically appropriate.
2. Listed Buildings
If your property is a listed building, any external alteration—cladding included—will almost certainly require Listed Building Consent, regardless of the material or style. This applies even if you're simply replacing existing cladding with new panels.
Failing to get consent can lead to serious penalties, including fines or forced restoration at your expense.
3. Areas of Outstanding Natural Beauty (AONB)
Large parts of Dorset fall within the Dorset AONB, such as areas around Cranborne Chase and West Dorset. Properties in these locations are often subject to stricter regulations to preserve the visual integrity of the landscape. Even minor cladding updates might require planning permission.
If you’re not sure whether your property lies within an AONB, you can check the Dorset Council’s planning map or consult a local planning officer.
Building Regulations and Cladding
Even if you don’t need planning permission, your cladding project must still comply with UK Building Regulations. These regulations cover:
-
Thermal performance (Part L)
-
Structural safety (Part A)
-
Fire safety (Part B)
-
Ventilation and moisture control (Part C and F)
For example, following the Grenfell Tower tragedy, fire safety rules for cladding—especially on multi-storey buildings—have become significantly stricter.
In Dorset, compliance with these regulations is enforced by local building control. Your installer should provide documentation that the work meets standards. If they don’t, you could be held responsible as the property owner.
Do Commercial Properties Need Permission?
If you're cladding a commercial property in Dorset, the rules are often more restrictive than for residential homes. Most cladding changes to commercial buildings do require planning permission, particularly if the work alters:
-
The overall appearance
-
Structural layout
-
Use class of the building
Businesses in town centres or tourist-heavy areas like Bournemouth, Poole, and Weymouth may face additional scrutiny to ensure visual consistency and community standards.
How to Apply for Planning Permission in Dorset
If you determine that your cladding project requires planning permission, here’s how to proceed:
-
Contact Dorset Council’s Planning Department
They can provide pre-application advice and help you understand what permissions are needed. -
Submit a Planning Application Online
You can do this through the Planning Portal or directly via the Dorset Council website. -
Include Detailed Plans
Your application should include elevations, material samples (if possible), and a description of the work. -
Wait for Approval
Decisions usually take 8 weeks, but can be longer in complex or heritage-sensitive cases.
Tips to Stay Compliant
To ensure your cladding in Dorset project stays legal and hassle-free, follow these tips:
Check Your Property’s Status
Use your postcode to search Dorset Council’s interactive maps for AONB, conservation area, or listed status.
Use Experienced Installers
Choose a contractor who understands both cladding installation and Dorset’s planning rules. They can guide you through permissions and compliance.
Keep Everything Documented
Retain copies of permissions, materials specs, fire ratings, and certifications. If you sell the property, you’ll need them for legal purposes.
Go for Visual Harmony
Use cladding materials and colours that complement local architecture. This increases your chances of approval and helps maintain neighbourhood aesthetics.
Popular Cladding Choices in Dorset
The style of cladding you choose should not only suit your taste but also fit Dorset’s planning context. Popular options include:
• Timber Cladding
Favoured in countryside and coastal areas for its natural appearance—works well in traditional and modern builds.
• Fibre Cement Board
A fire-resistant option suitable for urban settings. Mimics timber, brick, or stone.
• uPVC Cladding
Low maintenance and weather-resistant, ideal for modern homes or coastal properties.
• Composite Cladding
A sustainable and stylish choice, often made from recycled wood fibres and plastic—great for eco-conscious homeowners.
Always check that your chosen material meets Dorset’s fire safety and visual standards.
Final Thoughts
Installing or upgrading cladding in Dorset is a fantastic way to improve your property’s look, performance, and value. But before you get started, it’s critical to check whether planning permission is required—especially if you live in a conservation area, own a listed building, or are located within the Dorset AONB.
With the right preparation, a compliant design, and guidance from knowledgeable professionals, your cladding project can enhance your property while respecting the character and rules of this beautiful county.
