Legislate for a phased transition to full use of metric units. From 2031 convert road signage to kilometres, require all new vehicles to display km/h as the primary speed unit, issue binding guidance to public bodies, & mandate metric units in property descriptions enforced via Trading Standards.

The UK already uses metric units in most areas of daily life. Miles now remain mainly in road transport, some sports and leisure, and land or property descriptions. We believe this inconsistency causes confusion and inefficiency. Completing the transition to kilometres would improve clarity and international alignment.
