Have you got an idea, query, or a challenge to our standards?

If you would like to give feedback on one of our Design Manual for Roads and Bridges (DMRB) or Manual of Contract Documents for Highway Works (MCHW) standards, please use our new feedback form (click on the text 'feedback form' to open the form).

The information you provide will be forwarded to the technical author responsible for the document, and a response sent to you shortly. Your feedback helps us keep standards documents up-to-date and alerts us to ideas for future research and development. 

For any issues using the form or queries not related to standards, please email standards_enquiries@nationalhighways.co.uk
