Bathroom Knock Through

If ure taking out any load bearing wall it should be checked by building control after works are underway they will check that the work is done correctly , also u can get advice from structural engineer . Hope this helps

This is not a daft question at all. In fact, the fact that you’ve received two different structural solutions is exactly why it’s worth asking.

Many people assume every load-bearing wall removal requires an RSJ (steel beam), but that’s not always true.

Although it is only a short span, to what you have described it seems load bearing and it could be the support to a purlin, unsure until actually seen. However this can only be concluded correctly by assigning a Structural Engineer who would be best to advise. I understand structural design but i am not accredited, A Structural Engineer would be a requirement under current Building Regulations and if you carry out he works without involving an independent or local council inspector you may also breach your home insurance or home mortgage (if you have any) should anything happen in the future. If it is costs you are trying to save then a Structural Engineer can assess and conclude the requirement with this in hand their report will provide the appropriate design solution. The instruction of a Building Inspector protects you as it ensures that the works are carried out in compliance and any recall will be on the inspector, not you.

If the wall is confirmed load bearing, it will need proper structural support — so you’re right to question the different options.
A standard lintel is sometimes used for smaller openings, but it depends entirely on what load is above. From what you’ve described (especially with a stack of bricks supporting a beam in the loft), that load needs properly assessed — not guessed.
A timber frame or bracket solution from a joiner wouldn’t be suitable for supporting a load-bearing wall in this situation. This type of work should be done with a correctly sized steel (RSJ) or engineered support, based on calculations.
In terms of Building Regulations — removing or altering a load-bearing wall does normally require approval, regardless of the size. This protects you long term (especially for resale and insurance), so it’s definitely worth doing properly rather than skipping it.
Best route would be: • Confirm the wall is load bearing
• Get a structural engineer to specify the correct support
• Install steel/lintel as per spec
• Have it signed off under Building Regs
Both options you’ve been given sound a bit like “making it work” rather than doing it by the book. It might cost slightly more upfront, but doing it properly avoids issues down the line.

It is very common for the wall between a separate bathroom and toilet to be load-bearing, particularly if it sits directly under a roof purlin or supports floor joists. Because you have identified a single stack of bricks supporting a beam in the loft, this is definitely a load-bearing wall, and removing it requires careful planning to prevent ceiling sagging or roof damage.

Hi just get Structual engineer to be on the safe side as any movement could make the roof sag

As the wall in question is a supporting (load-bearing) wall, it should not be removed without providing proper structural support.
For an opening of around 1.8m, it is sometimes possible to use a suitable lintel instead of an RSJ, but this depends entirely on what load the wall is carrying above. The fact that there is a stack of bricks in the loft supporting a beam across the roof suggests that this wall is taking structural load, so this needs to be assessed properly.
A timber frame or bracket solution built by a joiner would generally not be considered an appropriate structural replacement for a load-bearing wall unless it has been specifically designed by a structural engineer.
Even though the opening is under 3 metres, Building Regulations still apply when altering or removing a load-bearing wall. In most cases, Building Control approval is strongly recommended to ensure the correct support is installed and to avoid issues when selling the property in the future.
The safest and most professional approach is to have the wall assessed by a structural engineer, who can specify whether a lintel or steel beam is required. This specification can then be submitted to Building Control for approval.
In short, both suggested options may work in certain situations, but they should be properly designed and approved. Taking the Building Regulations route provides peace of mind and protects you long-term.

Firstly when it comes to walls being removed I always recommend a professional assessing this because it a structural surveyor or architect. We then follow their plans to make sure it is 100% sound. You can't guess which catnic, lintel or rsj needs to be used, let people trained in this field decide

Any alterations of a structural wall should always be inspected by a structural engineer to add the Load and come up with a solution for the needs of your project. For small knock threes ie for a door way can be supported by a lintel and does not need inspecting but for instance if you are advised by the structural engineer you need an rsj the building inspector will always need to see the job and have the calculations by the engineer. In my past experience you are always better safe getting professional advice by the engineer other wise you may have problems selling your house in the future, not only that you do run the risk of having g problems down the line. Key note from this is better safe than sorry. I hope your project goes well but always ensure you get profession help in the situations

Thank you for your message.
Since the wall in question is a load-bearing (supporting) wall, it’s important that any structural changes are properly assessed. Even though the span is relatively small (around 1.8m), removing a supporting wall normally requires either a steel beam (RSJ) or a suitable lintel designed to carry the load — depending on the structural layout and what’s above.

The correct method can only be confirmed after a structural engineer’s assessment, which will specify the correct size and type of support.

Regardless of what the contractors have said, Building Regulations approval is still required for removing or altering a load-bearing wall. This ensures safety and compliance, and you’ll also get the completion certificate needed if you sell the property later.

My advice would be to have a structural engineer inspect the wall and provide calculations, then submit these under a Building Notice before work starts. It’s the safest and most reliable approach.

Renovating your bathroom by combining the separate bathroom and toilet spaces sounds like a great plan! Given the supporting wall in between and the single stack of bricks in the loft supporting a beam across the roof pitch, let's break down the contractors' suggestions and the building regulations aspect.

Contractor Suggestions Assessment
• Lintel Solution: A lintel might suffice for a 1.8m-wide opening in a load-bearing wall, especially if the wall above isn't carrying significant loads and the loft's brick stack and beam are adequately supporting the roof structure. However, a structural engineer's assessment is crucial to confirm.
• Frame/Bracket Solution: A custom frame or bracket designed by a joiner to spread the load could also work, depending on the design, materials, and the specific load distribution requirements. Again, a professional evaluation is necessary to ensure safety and efficacy.

Building Regulations Considerations
• Approval Requirement: Removing a load-bearing wall typically requires Building Regulations approval to ensure structural integrity, fire safety, and other aspects. However, for smaller projects or specific exemptions, you might not need formal approval, but consulting with your local Building Control or an Approved Inspector is wise.
• Prudence Advised: Even if both contractors claim their solutions don't require Building Regulations approval, it's prudent to:
? Consult a Structural Engineer: For a definitive assessment of the wall's load-bearing capacity and the appropriate support solution.
? Check with Building Control: Confirm whether your project requires approval and, if so, follow the proper application and inspection process to avoid future complications, especially when selling your property.
? Documentation: Keep detailed records of all work, designs, and assessments for future reference and proof of compliance.

Recommended Next Steps
1. Hire a Structural Engineer: Get a professional assessment of the wall and the required support structure.
2. Consult Local Building Control: Discuss your project with them to clarify approval requirements and processes.
3. Evaluate Contractor Proposals: With expert advice, assess the contractors' solutions for safety, compliance, and suitability.

Given your situation, it's understandable that you're questioning the suggestions from both contractors. Let's break down the key points to consider:

Load-Bearing Wall Removal
Removing a load-bearing wall requires careful planning and execution. Since the wall supports a beam across the pitch of the roof, you'll need a suitable replacement support structure.

Lintels vs. RSJs
• Lintels: A lintel is a horizontal beam that spans openings in walls, supporting loads from above. For a load-bearing wall like yours, a lintel might be sufficient if it's properly sized and installed. However, a structural engineer's assessment is crucial to determine the correct type and size of lintel required.
• RSJs (Rolled Steel Joists): RSJs are often used for larger openings or heavier loads. Given the span and load in your case, an RSJ might be a more suitable option, but again, a structural engineer's input is necessary.

Contractor Suggestions
• First Contractor's Suggestion: A lintel might be sufficient, but ensure it's designed and installed correctly. Request detailed calculations and specifications from the contractor.
• Second Contractor's Suggestion: A frame or bracket to spread the load could work, but it's essential to verify its structural integrity and compliance with building regulations.

Building Regulations
Even if both contractors claim their solutions don't require building regulations approval, it's highly recommended to consult with a structural engineer and Building Control to ensure compliance. Removing a load-bearing wall is a significant alteration that typically requires approval .

Recommended Steps
1. Consult a Structural Engineer: Get a professional assessment of the wall and the load it bears. They can recommend the best solution and provide necessary calculations and specifications.
2. Verify Building Regulations: Check with your local Building Control to determine if approval is required. Even if the contractors claim exemption, it's better to err on the side of caution.
3. Get Multiple Quotes: Obtain quotes from multiple contractors, ensuring they all follow the structural engineer's recommendations and comply with building regulations.
4. Ensure Warranty and Liability: Clarify the warranty and liability terms with your contractors. A reputable builder will provide a warranty for their work

1. The wall is supporting something.

You’ve confirmed there’s a stack of bricks supporting a roof beam sitting above that wall.

That means the wall is load-bearing (not just a partition).

Any time a supporting wall is altered or removed, it must be replaced with something that can take the load properly (lintel, RSJ, or other engineered solution).

2. Lintel vs RSJ vs Joiner’s frame

Concrete or steel lintel:

Suitable for short spans (like your 1.8m wall), if it’s the right size, depth, and bearing.

Still needs to be sized correctly to carry the load — not just guessed.

RSJ (rolled steel joist):

Overkill for some smaller jobs, but often the “go-to” because building control officers like it — they know it works.

More disruptive to fit but gives peace of mind.

Joiner’s frame/bracket solution:

This sounds like a timber goalpost frame (two uprights + a head beam) to spread the load.

These can work if designed properly, but unless backed by an engineer’s calcs, it’s risky.

“We’ll just build a frame” isn’t the same as having it designed to take the actual load.

3. Building Regulations

Because the wall is structural, Building Regulations definitely apply.

Even if the span is under 3m, you still need it checked, and usually a Building Control Officer or a structural engineer’s calculation is required.

If you go ahead without regs and sell your home later, a surveyor will flag it and you may have problems with indemnity insurance or re-sale value.

Removing a load-bearing wall always requires Building Regulations approval, even for a short span. Whether you use a lintel, RSJ, or custom bracket, get a structural engineer’s advice and notify Building Control to stay safe and compliant.

I would suggest getting a building engineer to check the load and specify what to use. get this wrong and your roof could cave in. I would most definitely get it checked by building control for safety and peace of mind.

This sounds incorrect and when messing with the supporting walls a structural engineer should offer the solution.

We would be looking to engage an engineer to make sure everything is correct (this would include consulting the building regulator)
