If you want genuinely local jobs, not just local collections with long-distance deliveries, use the nearby filter that keeps both collection and delivery within your chosen radius.
1Why this happens
Nearby search starts from the collection side of the market. That means some jobs will begin in your area but finish much further away.
2How to tighten it
Open the nearby filters and use the option that limits results to jobs where both ends sit within the nearby radius. This is the quickest way to make the search feel more local.
3When to switch modes
If you actually want route-shaped work rather than only local two-end jobs, corridor search is usually the better tool.
