Building Regulations for Wall Removal: What You Actually Need

Removing a load-bearing wall requires Building Control approval. This guide explains what Building Regulations apply to wall removals, what you need to submit, how long approval takes, and what happens at inspection to in plain English.

Do You Need Building Regulations for Wall Removal? The Short Answer

Yes, if the wall is load-bearing. Building regulations for wall removal fall under Part A (Structure), which applies to any work that changes the structural elements of a building. Removing a load-bearing wall changes the structure, so Building Control approval is required before the work starts.

Non-load-bearing partition walls do not require Building Regulations approval. If your builder and structural engineer have confirmed the wall is not load-bearing, you can remove it without a Building Control application.

Building Regulations for Wall Removal: Full Plans vs Building Notice

There are two main routes to Building Control approval for a wall removal. Understanding the difference before you start can save you significant time and money.

Full Plans application (recommended)

You submit your structural engineer's calculation pack and drawings to Building Control before work starts. Building Control reviews the documents and issues a plans-passed notice, usually within five working days for a straightforward domestic wall removal. Work can then proceed with confidence that the design has been pre-approved.

The advantage of Full Plans is legal certainty. If Building Control approves the plans and the work is built to those plans, they cannot later require you to undo it. This matters if you plan to sell the property.

Building Notice

A Building Notice allows you to start work almost immediately without submitting drawings for prior approval. The inspector visits during and after the work and checks compliance on site. This sounds quicker, but it carries a significant risk: if the inspector finds something non-compliant after the work is done, you may have to remove and redo it at your own cost. For a straightforward wall removal with a clear structural engineer's pack, a Building Notice can work. For anything more complex, Full Plans is safer.

In most cases, we recommend Full Plans. The five-day wait for plans approval is a small price for the legal certainty it provides.

Building Regulations for Wall Removal: What to Submit

For a Full Plans application for a load-bearing wall removal, you need:

• Structural calculations: the engineering mathematics proving the beam design is safe. Produced by a qualified structural engineer.
• Structural drawings: clear drawings showing the beam position, size and padstone details. Included in the structural engineer's pack.
• Existing floor plan: showing where the wall being removed is located in relation to the rest of the property.
• Proposed floor plan: showing the property after the wall removal.
• Building Control application form: the standard form for your local authority or private approved inspector.
• Application fee: typically £200 to £500 for a domestic wall removal.

Your structural engineer's calculation pack covers the first two items to calculations and drawings to and is formatted specifically for Building Control submission. See our guide: wall removal structural calculations and structural calculations for Building Control.

Building Regulations Wall Removal: The Process Step by Step

1. Appoint a structural engineer. Get your calculation pack produced before you do anything else. The calculations are what the Building Control application is built around.
2. Choose your Building Control authority. You can use your local council's Building Control service or a private approved inspector. Private inspectors are often faster and can be more flexible, but check they are registered with the Building Safety Regulator.
3. Submit your Full Plans application. Send the calculation pack, drawings, floor plans and application form. Pay the fee. Keep a copy of everything.
4. Wait for plans approval. Building Control will respond within five working days for a straightforward domestic application. They may come back with technical queries to your structural engineer responds to these as part of their service.
5. Notify Building Control before work starts. Once plans are approved, you must notify Building Control that you are about to start. They will arrange an inspection during and after the work.
6. During work: the inspector visits. The inspector checks that the beam, padstones and propping are installed correctly before walls are closed up. Do not close up the beam position until the inspector has signed off the structural work.
7. Completion certificate. Once all work is finished and inspected, Building Control issues a completion certificate. Keep this to you will need it when you sell the property.

What the Building Control Inspector Checks

For a load-bearing wall removal, the inspector focuses on:

• Whether the correct RSJ beam has been installed (matching the structural engineer's specification)
• Whether the padstones are correctly sized and positioned at each bearing end
• Whether the beam is properly bedded and level
• Whether any temporary propping has been removed safely after the beam is in place
• Whether the masonry below the padstones is sound and adequate

The inspector is not checking the quality of your decoration or the choice of flooring. Their role is specifically the structural elements.

FAQ: Building Regulations for Wall Removal

Do I need planning permission to remove an internal wall?

No. Internal wall removals do not require planning permission. They require Building Control approval if the wall is load-bearing, but planning permission is a separate regime that applies to changes to the external appearance and use of a building.

What if I remove a wall without Building Control approval?

The work becomes unauthorised. When you sell the property, your solicitor will ask for the Building Control completion certificate. Without it, the buyer's solicitor will raise enquiries, the buyer may pull out, or you may need to take out indemnity insurance (which does not guarantee the work was done correctly). Some lenders will not mortgage a property with unauthorised structural works.

How long does Building Control approval take?

For a Full Plans application for a domestic wall removal, typically five working days for plans approval. The full process from submitting plans to receiving a completion certificate typically takes four to eight weeks depending on how quickly the build progresses and when inspections are booked.

Can I use a private Building Control inspector instead of the council?

Yes. Private approved inspectors (registered with the Building Safety Regulator) offer the same legal approval as the local authority but are often faster and more accessible. The process and the completion certificate are equivalent.
