1. Do You Need Planning Permission for Chimney Breast Removal in London?

In most cases, planning permission is not required for chimney breast removal if it’s done entirely within your property and doesn’t alter the exterior appearance of the building. However, there are important exceptions:

  • Listed Buildings: If your property is listed, you’ll need Listed Building Consent regardless of whether the work is internal or external.
  • Conservation Areas: If your home is in a conservation area, planning permission may be required if the removal affects the building’s character or external appearance.
  • External Changes: If the removal involves altering or demolishing the chimney stack visible from the street, you’ll likely need planning permission.
  • Flats and Apartments: Structural changes in flats or apartments usually require permission from the freeholder and may also need planning permission due to shared walls or communal structures.

2. When Is Planning Permission Not Required?

You do not need planning permission for chimney breast removal if:

  • The work is entirely internal and does not affect the external appearance of the property.
  • The property is not listed or located in a conservation area.
  • The removal doesn’t compromise the structural integrity of the building.

However, even if planning permission isn’t required, the work must comply with Building Regulations to ensure structural safety. This includes:

  • Structural Calculations: To confirm that the remaining structure can support the load.
  • Support Systems: Installing appropriate supports, such as steel beams or gallows brackets.
  • Building Control Approval: Inspection and certification by your local council’s building control department.

We handle all aspects of Building Regulations compliance at our Company, from structural assessments to building control approvals, ensuring your project is safe and legal.

3. When Is Planning Permission Required?

You’ll need planning permission for chimney breast removal in the following situations:

a. Listed Buildings
If your property is a Listed Building, you must obtain Listed Building Consent before any alterations, including chimney breast removal. This is because chimney breasts are considered part of the building’s historical fabric. Unauthorized removal can result in significant fines.

b. Conservation Areas
In London, many neighborhoods are designated as Conservation Areas to preserve their historical or architectural character. If removing a chimney breast affects the building’s external appearance or character, you’ll need planning permission.

This typically applies if:

  • The chimney stack is visible from the street.
  • The work alters the external roofline or facade.

Our team conducts thorough site assessments to determine whether your property is in a conservation area and advises on the necessary permissions.

c. External Changes
If chimney breast removal involves altering or demolishing the chimney stack visible from the street, planning permission is required. This is because external changes can affect the property’s architectural integrity and the overall streetscape.

d. Flats and Apartments
In flats or apartments, structural changes affect shared walls or communal structures, making planning permission necessary. Additionally, you’ll need permission from the freeholder or management company before proceeding.

4. How to Apply for Planning Permission in London

If planning permission is required, the process involves:

a. Preparing Detailed Drawings and Documents
You’ll need to submit the following to your local council:

  • Architectural Drawings: Detailed plans showing the existing and proposed structures.
  • Structural Calculations: Demonstrating that the remaining structure is safe.
  • Design and Access Statement: Explaining the design choices and impact on the property.

Our team provides comprehensive support, from preparing structural drawings to submitting the planning application on your behalf.

b. Submitting the Application
Planning applications are submitted through the Planning Portal or directly to your local council’s planning department. The application fee varies depending on the scope of the project.

c. Consultation and Decision
The council will consult neighbors and relevant stakeholders, considering factors such as:

  • Impact on Neighboring Properties
  • Effect on the Character of the Area
  • Compliance with Local Planning Policies

The decision typically takes 8-12 weeks. If approved, the permission is valid for 3 years.

5. Building Regulations Approval: A Separate Requirement

Even if planning permission isn’t required, you’ll still need Building Regulations approval. This ensures the work is structurally safe and compliant with safety standards.

Our structural engineers provide:

  • Structural Assessments
  • Design and Calculation Reports
  • Building Control Coordination
  • On-Site Inspections and Certification

We handle the entire Building Regulations process, ensuring full compliance and peace of mind.
