How much does a structural engineer typically charge?

Engineering fees genuinely vary with project complexity, scope, and the specific engineer or firm — a straightforward standard house slab design costs meaningfully less than a complex sloping-site foundation or a commercial structural design.

Some engineers price as a fixed fee for standard residential work, while more complex or bespoke projects may be priced based on time or project value — worth clarifying directly with your engineer at the outset rather than assuming a fixed industry-standard rate exists.

Engineering fees are a genuine, worthwhile investment — they’re what makes your foundation design safe, compliant and appropriately specified for your actual site, not a cost to minimise by seeking the cheapest option regardless of quality.
