Can You Remove a Load-Bearing Wall?

Structural Changes Done Safely, With Clear Costs From the Start

In most homes, yes—a load-bearing wall can usually be removed when the load is transferred correctly using steelwork (often an RSJ/beam) and appropriate supports. The real risk isn’t the idea of removal; it’s removal without the correct design, temporary support, and compliant installation.

If you’ve seen online advice like “check the loft” or “tap the wall”, treat it as a starting point only. London homes often have extensions, previous alterations, and mixed construction methods that make quick assumptions unreliable.

How to Tell If a Wall Is Load-Bearing

Here are common signs a wall may be load-bearing:

It runs through the centre of the house

Walls positioned front to back or side to side often support the structure above.

Wall directly above it on the upper floor

Stacked walls usually transfer loads down to the foundations.

It connects to an external wall

Internal walls tied into exterior walls often help distribute loads.

The property has had a loft conversion or extension

Structural changes can redirect loads onto walls that were not originally load-bearing.

The home is older (pre-1960s construction)

Older houses commonly rely on internal load-bearing walls rather than steel frames.

Floor or ceiling joists rest on the wall

If joists end or overlap directly on the wall, it is likely carrying weight.

The wall supports a beam, column, or post

Any visible beam or post resting on the wall suggests a structural role.

It supports a chimney breast or fireplace

Chimney structures are heavy and almost always require load-bearing support.

The wall runs perpendicular to joists rather than parallel

Walls crossing joists typically provide support, while parallel walls often do not.

Thick walls or masonry construction

Solid brick or block walls are more likely to be load-bearing than stud partitions.

👉 Important: These checks can guide you, but they don’t confirm the structure. The safest approach is assessment using your layout/drawings, and where needed, a structural engineer’s confirmation.

How Much Does Load-Bearing Wall Removal Cost in London?

Costs vary based on span, loads above, access, and finish level.

Most people under-budget by forgetting engineering + Building Control + making good.

RSJ Installation and What It Actually Means

“RSJ” is often used to describe the steel beam that replaces a wall’s structural role. In practice, the correct solution might be a steel beam, flitch beam, or other engineered support—chosen based on calculations, span, and load.

A proper RSJ/steel installation typically involves:

Temporary supports (Acrows/strongboys)

Controlled removal of the wall

Making good (plastering/finishes)

Compliance checks for Building Control

Why a Structural Engineer Is Often Required

When removing a load-bearing wall, a structural engineer is often required to confirm how the building’s weight will be safely supported once the wall is removed. This isn’t just a formality — it’s what ensures the work is designed correctly from the start.

A structural engineer will assess your property and provide calculations and drawings that specify the correct beam size and support method. These documents are usually required for Building Control approval and help ensure the alteration doesn’t compromise the structural integrity of your home.

Removing or altering a supporting wall without proper design can lead to movement, cracking, or more serious structural issues. In some cases, it can also create problems later when selling the property or during inspections.

That’s why involving a structural engineer isn’t about adding unnecessary steps — it’s about making sure your renovation is safe, compliant, and properly documented.

A structural engineer is often required to:

Confirm whether the wall is load-bearing

Calculate the correct beam size

Specify the correct support method

Produce drawings and calculations

FAQ

Can you remove a load-bearing wall safely?

Yes—when loads are transferred correctly using a properly designed support solution (often steel). The critical part is the design + sequencing: temporary supports go in first, and the wall is removed only once the structure is safely supported. A well-run job looks calm and controlled, not rushed. We focus on doing it properly so you don’t end up with cracks, movement, or compliance issues later.
How do I know if my wall is load-bearing?

Central walls, aligned walls across floors, and walls that support joists are common indicators. But London homes often have altered layouts, which makes quick visual checks unreliable. The safest approach is reviewing the layout and, where required, confirming with calculations. If you upload a plan/photo, we can usually give a practical direction quickly.
How much does load-bearing wall removal cost in London?

Costs depend on span, beam requirements, access, and finish level. Two walls that “look the same” can price very differently if one requires more steelwork, more propping, or service moves (electrics/plumbing). That’s why we recommend using the cost guide for ranges, then the AI estimate for a personalised breakdown. It saves time and prevents budget shocks later.

Do I need a structural engineer to remove a load-bearing wall?

In many cases, yes—especially when Building Control approval is needed. The engineer provides calculations and drawings that specify the correct beam size and support details. This protects your home structurally and makes compliance straightforward. If your situation is simpler, we’ll tell you honestly and avoid unnecessary steps.
Is Building Control approval required for load-bearing wall removal?

Yes, structural wall removal normally requires Building Control approval, even if planning permission is not needed. Building Control ensures the work complies with safety regulations and that the structural solution is appropriate. Skipping this step can cause serious problems later, particularly during property sales or insurance claims. We explain what’s required for your specific situation and guide you through the correct process.
How long does load-bearing wall removal take?

The structural stage of removing a load-bearing wall often takes one to two days, depending on the complexity of the work. Additional time may be needed for plastering, decorating, or relocating services such as electrics or plumbing. Preparation, temporary supports, and safety measures are all factored in before work begins, so the process runs smoothly and without unnecessary disruption.
Will my home be safe while the wall is being removed?

Yes, safety is managed throughout the process. Temporary supports are installed before the wall is removed, ensuring the structure remains stable at all times. The wall is never taken out without proper load support in place. This staged approach is critical and is one of the main reasons load-bearing wall removal should always be handled by experienced professionals.
Do I need planning permission to remove a load-bearing wall?

In the UK, removing a load-bearing wall usually requires Building Regulations approval, rather than Planning Permission. For most straightforward projects, this is handled through a Building Notice, with structural calculations submitted to your local authority or an approved inspector. These checks ensure the new beam and supports are designed correctly and that the work meets safety and compliance standards before it begins.
Will removing a load-bearing wall add value to my home?

In many cases, yes. Opening up layouts can significantly improve how a home feels and functions, particularly in kitchens and living areas. Buyers often value open-plan spaces, provided the work has been carried out correctly and documented. Proper structural work and approvals help ensure the improvement adds value rather than raising concerns later.
What happens if I remove a wall without proper approval or calculations?

Removing a load-bearing wall without proper design or approval can lead to structural damage, failed inspections, and problems when selling your home. In serious cases, it can also affect insurance cover. Retrospective approvals can be costly and stressful. Getting things assessed correctly from the start avoids these risks entirely.
What should I do before deciding to remove a load-bearing wall?

The best first step is to understand whether the wall is structural and what the likely costs and requirements are. Looking at generic prices online can be misleading, as every property is different. Using an estimate based on your actual layout or speaking with a Growchance specialist gives you clarity before committing to anything. This approach helps you make decisions with confidence rather than guesswork.
