No, for most roads, there isn't. The Highway Code does say that you shouldn't cross within the zigzag lines of a "proper" crossing, but that's just Best Practices, and not enforceable. There are also roads where pedestrians are excluded altogether (no possibility of a footpath, no walking on the verge, fenced off apart from sliproads). The same rules exclude low-powered and slow vehicles from those roads too.
