GUIDE TO CHIMNEY BREAST REMOVAL

Chimney breast removal is a significant home improvement project often pursued in older homes, particularly in London, where Victorian and Edwardian properties are common. It can transform a space by creating more room, improving the flow of a room, or facilitating renovations such as open-plan living areas. However, the process is complex and requires careful planning, knowledge of local building regulations, and understanding of associated costs.

What is a Chimney Breast?

A chimney breast is the portion of the chimney that projects from the wall, typically within the room itself. It includes the structural brickwork surrounding the fireplace and can extend into the living space. This structure often houses a fireplace or stove. In older homes, chimney breasts were a prominent feature of the home’s design, but they can be seen as an obstruction in modern living spaces. Many homeowners in London opt to remove the chimney breast to reclaim valuable space or modernize the design of a room.

Reasons for Chimney Breast Removal

There are several reasons why homeowners in London may choose to remove a chimney breast:

Space Creation: Chimney breasts can take up valuable floor space, particularly in small or narrow rooms. Removing them opens up more usable space, making the room feel more expansive.
Modernization: Many homes in London are older properties with outdated designs. Removing a chimney breast can modernize the living space, enabling homeowners to create an open-plan layout, particularly in living and dining areas.
Renovation Projects: If you're renovating a home and wish to make the space more functional or aesthetic, removing the chimney breast allows for greater flexibility in designing the layout of the room.
Energy Efficiency: In some cases, if the chimney is not in use and the flue is causing heat loss, homeowners may remove the chimney breast as part of an effort to improve energy efficiency.
Repositioning Heating Appliances: If you no longer use the fireplace or stove, removing the chimney breast allows you to place heating systems like radiators or underfloor heating where the chimney once stood.

Steps Involved in Chimney Breast Removal in London

Chimney breast removal is a major undertaking that requires professional expertise due to the structural and safety concerns involved. Below is an outline of the typical steps in this process:

1. Initial Assessment and Consultation

Before starting the chimney breast removal process, it's crucial to hire a structural engineer or certified contractor to assess the property. The engineer will:

Determine the type of chimney breast (whether it’s part of a load-bearing wall or simply a decorative feature).
Assess the structural integrity of the wall and ceiling to ensure that removing the breast won't affect the overall stability of the building.
Decide whether the chimney is still in use or can be safely decommissioned.

2. Planning and Permission

In London, chimney breast removal typically requires planning permission or, at the very least, adherence to local building regulations. Depending on the nature of the removal, you may need to obtain approval from your local council or planning authority, especially if:

The property is listed or in a conservation area.
The chimney breast is a load-bearing structure, requiring structural reinforcements post-removal.

For non-listed buildings, planning permission might not be necessary for removal of the chimney breast itself, but structural changes will need approval.

3. Decommissioning the Chimney

If the chimney is still in use, it will first need to be safely decommissioned. This involves:

Sealing the flue and capping it to prevent drafts or heat loss.
Disconnecting any appliances that use the chimney, such as a fireplace or stove.
Removing the chimney liner, if applicable, and ensuring there are no hazards left behind.

4. Supporting the Structure

If the chimney breast is part of a load-bearing wall, significant support is required before removal. Temporary structural supports, such as acrow props, are used to bear the weight of the structure while the chimney breast is being removed. A structural engineer will calculate the necessary supports and ensure the wall can handle the load during and after removal.

5. Removing the Chimney Breast

Once the chimney has been decommissioned and supports are in place, the chimney breast can be carefully removed. This is usually done brick by brick, starting from the top down. The process can be messy and may require scaffolding for easier access to higher parts of the chimney. The surrounding walls, ceiling, and floor will also need to be repaired and refinished after the removal.

6. Rebuilding and Reinforcing

After the chimney breast is removed, repairs will be needed to restore the walls, ceiling, and flooring. In some cases, a new supporting beam or steel lintel will need to be installed to reinforce the structure. The area will be made good, with new plastering, redecorating, or even re-plasterboarding to ensure the room looks clean and seamless post-removal.

7. Cleaning and Final Inspections

Finally, the area will be cleaned of debris and dust. In some cases, an inspection by a building control officer may be required to ensure everything complies with regulations.

Chimney Breast Removal Cost in London

The chimney breast removal cost in London varies based on several factors, including the size of the chimney, the complexity of the removal, the type of property, and the region. Here’s a breakdown of the typical costs:

1. Average Cost

On average, chimney breast removal in London can cost between £1,500 and £5,000. This price range includes all necessary labor, materials, and structural adjustments.

2. Factors Affecting Cost:

Size and Location of the Chimney: Larger chimneys, especially those in multi-storey homes, can increase the overall cost due to additional labor and equipment (e.g., scaffolding, cranes).
Structural Modifications: If the chimney breast is load-bearing, additional work to reinforce the structure, such as installing steel supports or beams, will increase the cost.
Disposal of Materials: The cost of removing the materials (such as bricks, plaster, and rubble) from the site will also add to the price, especially if the removal is extensive.
Location: Costs in central London or areas with high demand for contractors can be higher due to labor rates and access considerations.

3. Chimney Removal Cost:

If you're removing the entire chimney stack (as well as the breast), the chimney removal cost will be higher, ranging from £3,000 to £7,000, depending on the height and complexity of the chimney. This cost includes the removal of both the chimney breast and stack, as well as any required roof repairs.

4. Labor and Materials:

Labor costs for chimney breast removal can vary between £150 to £350 per day, depending on the contractor's experience and location in London. The cost of materials for the structural modifications can add up to several hundred pounds.

Additional Considerations for Chimney Breast Removal in London

Listed Buildings and Conservation Areas: If your property is listed or within a conservation area, it’s vital to check whether you can remove the chimney breast at all, or if you’ll need to preserve certain elements of it. The planning process can be more complex and may take longer.
Structural Risks: Removing a chimney breast, particularly one that is load-bearing, can affect the overall stability of your home. Hiring a qualified structural engineer is essential to ensure your home remains safe and sound after the work is completed.
Asbestos: Older chimneys may contain asbestos, which requires careful handling and disposal by a licensed contractor.
Disruption and Clean-Up: Chimney breast removal is a messy and disruptive process, especially in terms of dust and debris. It's important to prepare for this and ensure the work is carried out by professionals who will handle the cleanup.

Conclusion

Chimney breast removal in London can significantly improve the design and functionality of your home, but it's a complex and often costly process. The chimney breast removal cost typically ranges from £1,500 to £5,000, with additional costs for structural modifications, disposal, and potential roof repairs. If you're considering chimney removal or chimney breast removal, working with a certified contractor and structural engineer is essential to ensure that the job is done safely and in compliance with all relevant regulations.
