Understanding the Steel Beam Calculation Process
Many clients first find us through our video guide on the engineering behind beam design.
Our YouTube guide “How to do a steel beam calculation” is a popular resource for understanding the maths behind the design.
For your actual build, you need a professional design to satisfy regulations. We turn the theory into a certified calculation pack your builder can trust on site.

Common Questions: Steel Beam Calculation
Quick answers about costs, regulations and requirements.
Do I really need a steel beam calculation?
Yes. Guesswork is dangerous and does not comply with Building Regulations. A proper calculation ensures the beam can safely carry the load without sagging or collapsing.
How much does a steel beam calculation cost?
Fees vary based on complexity. Single beam calculations start from a few hundred pounds. Larger projects like extensions cost more. We always provide a fixed fee upfront.
How fast is the service?
For standard domestic projects, we aim to deliver the pack within 1–3 working days once we have all the necessary information.
Are the calculations Building Control compliant?
Yes. Our designs follow UK standards and are presented in the correct format for Building Control. We handle any queries they may have.
What info do I need to provide?
We need the property address, a description of the work, clear photos and basic measurements. Architect drawings are helpful but not always essential for simple beams.
Do you need to visit the site?
For simple beam designs, we can often work from photos and measurements. If the structure is complex, we will advise if a site visit is necessary.
