When Do You Need a Structural Engineer?

Many homeowners and developers are unsure when a structural engineer is required. In most cases, structural input is necessary whenever you are altering the load-bearing elements of a building.

You will typically require a structural engineer if you are:

• Removing a loadbearing wall

• Installing steel beams (RSJs)

• Undertaking a loft conversion

• Building an extension

• Constructing a new dwelling

• Converting a garage

• Underpinning or addressing subsidence

• Noticing significant cracking in walls

• Installing large openings or bi-fold doors

A structural engineer ensures that any alterations are safe, compliant and properly detailed for Building Control approval.
