There is no verified fee survey behind this site. We have removed the earlier fee bands rather than presenting them as current market evidence. Ask for a written proposal tied to your building, opening and required deliverables.
Define the appointment
Describe the proposed opening, location, existing construction and any drawings available. Ask whether the fee includes a visit, measurements, calculations, beam and connection drawings, bearing design, responses to Building Control and subsequent revisions. State if temporary-works design or construction-stage attendance is required; do not assume it is included.
Compare deliverables, not just the total
One proposal may cover a single assumed beam while another includes investigation of the full load path. Check assumptions about the existing building and what happens if a site finding invalidates them. Agree the price and process for additional work.
Ask how qualifications, relevant experience and professional insurance can be verified. Keep the appointment, issued revisions and correspondence together so that the installer works from the correct information.
Approval and construction
Design preparation and regulatory approval are separate responsibilities. Consult GOV.UK’s Building Regulations guidance for the applicable process; charges and requirements depend on the project and jurisdiction. Our online calculations are educational and cannot form the engineer’s signed design package.
The quote calculator accepts an already-gross professional fee as an additional cost. It does not predict that fee or add VAT to it again.
