Terms of use

The terms on which this website and the MEP design fee estimator are made available.

These terms cover use of this website. The terms on which SDE is appointed to carry out design work are a separate document, issued with the fee proposal, and nothing here forms part of them.

About these terms

This website is operated by Smith Design Engineering Ltd, registered in Scotland, company number SC713846. By using the site you accept these terms.

The fee estimator

The MEP design fee estimator on this site produces an indicative range only. It is provided for general guidance.

  • It is not a quotation, not a fee proposal and not an offer capable of acceptance.
  • It does not create a contract, and no appointment arises from using it.
  • It is generated from limited inputs and without sight of drawings, site conditions or the project brief.
  • A fee proposal is issued only after an engineer has reviewed the project information and confirmed the scope, deliverables and programme.

To the extent permitted by law, SDE accepts no liability for any decision taken in reliance on the estimator output.

Content on this site
