From December 2015.
Highway Code states the following regarding walking on a road with no pavement:
Rule 2
If there is no pavement, keep to the right-hand side of the road so that you can see oncoming traffic. You should take extra care and
- be prepared to walk in single file, especially on narrow roads or in poor light
- keep close to the side of the road.
It may be safer to cross the road well before a sharp right-hand bend so that oncoming traffic has a better chance of seeing you. Cross back after the bend.
