Free Structural Engineer Quote Template
Structural engineers quote separately from architects because structural calculations are a specialist service with professional liability. A clear quote sets the scope of the structural elements being designed and what inspection visits are included in the fee.

Frequently asked questions
How much does structural engineering cost for a house extension?
Structural engineering fees for a typical residential extension cost €800 to €2,500. A simple single-storey rear extension with a steel beam sits at €800 to €1,200. A two-storey extension with a complex roof and multiple structural elements costs €1,500 to €3,000. New build homes and larger projects cost more.
What is included in a structural engineer's quote for a renovation?
The quote should specify which structural elements are being designed (lintels, beams, columns, foundations), whether calculations are included, how many site visits are covered, and whether the engineer will sign off for building control. Calculations submitted to building control are a billable deliverable.
When do I need a structural engineer rather than just a contractor?
Any time you're removing a wall (load-bearing or otherwise), adding a floor, changing a roof structure, or building an extension, you need structural calculations. The building regulations authority will ask for an engineer's report. Your contractor can't provide this, and attempting the work without calculations is a building control risk.
