You need a structural engineer whenever a building project changes how loads are carried, removing a wall, inserting a steel beam, building an extension, converting a loft, or altering foundations. We confirm what the structure must support, design the right solution and provide calculations Building Control will accept.
- Removing or altering a load-bearing wall
- Designing a steel beam, lintel or padstone

Building Regulations & Building Control
Calculations prepared for approval
Most structural alterations require approval under the Building Regulations. Building Control, or an Approved Inspector, will want to see that any new or altered structural element has been designed by a competent engineer.
We prepare structural calculations and supporting details to current standards so they can be submitted as part of your Building Control application. Where Building Control raise queries, we respond to them directly to help keep your approval on track. Our calculations are produced to integrate cleanly with your architect's drawings and your builder's programme.
For a deeper look at what a Building Control submission involves, see our dedicated page on Building Regulations structural calculations.

Structural engineer London, questions
Do I need a structural engineer to remove a wall?
If a wall is load-bearing, or you are unsure whether it is, you need a structural engineer. We confirm whether the wall carries load, design any supporting beam and provide the calculations and details Building Control require before the wall is removed.
How long do structural calculations take?
Many domestic calculations, such as a single beam or wall removal, can be turned around within a few working days once we have suitable drawings. Larger or more complex projects take longer; we will confirm a realistic timescale when we review your information.
Do you provide drawings as well as calculations?
Yes. We provide structural calculations and the supporting structural details, such as beam sizes, padstones, connections and key dimensions. We can work alongside your architect's drawings or provide structural drawings where they are required.
Will your calculations be accepted by Building Control?
Yes. Our structural calculations and details are prepared to current standards for submission to Building Control or an Approved Inspector, and we can respond to any queries they raise during approval.
