Published standards and specifications are routinely reviewed and updated to reflect best practice. We welcome feedback on our standards from suppliers and other stakeholders. 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 the feedback form.
Where applicable, the feedback you provide will be forwarded to the technical author responsible for the document, and a response sent to you shortly.
Please note: The intention of the feedback form is to provide a route for feedback on or challenges to our standards to support their routine maintenance. This form is not intended as a route to obtain guidance on the application of a standard; please direct such queries via your project team as applicable.
The Manual of Contract Documents for Highway Works (MCHW) was modernised and republished 30 September 2025. If your query relates to these updates, please refer first to the MCHW Information hub which includes essential guidance to support the transition to the updated MCHW.
If you would like to provide feedback on the Standards for Highways website or the MCHW Information hub, please use the same feedback form.
If you have problems using the feedback form, please see our Accessibility statement for other ways to contact us.
