Government responded
This Government currently does not have plans to legislate on a set minimum space e.g. 1 metre on roads with a speed limit of up to 30mph when overtaking a cyclist.

This type of legislation would be extremely difficult to enforce and the Government does not believe that it would add to the existing rules and guidance, including those set out in the Highway Code, which advises drivers to give cyclists “at least as much room as you would when overtaking a car”.
We are keeping this position under review, and are interested in learning from the experience of places where legislation of this type has been introduced. One example is South Australia, where since 25th October 2015, drivers are required to give a minimum of one metre when passing a cyclist where the speed limit is 60km/h (37.3mph) or less or 1.5 metres where the speed limit is over 60km/h (40mph). The penalty for drivers caught disobeying this rule is a $287 (£148) fine, plus a $60 (£31) victim of crime levy and 2 demerit (penalty) points. However, it will take time to understand the benefits and impacts of this legislation on cyclists and other road users.
