Enter two postcodes or postcode areas in the calculator above to find out the distance between them.
You will be able to see the distance both "as the crow flies" (in a straight line) and by road. Road distance is calculated as the most efficient driving route, not necessarily the shortest distance.
Links to mapping services are also shown to make it easy to get directions.
This tool looks up the geographic coordinates of the centre of each postcode (known as the centroid), calculates the straight-line distance using longitude and latitude, and estimates driving distance using a route planner.
Distance data can be used for all sorts of purposes, including house hunting, planning deliveries, working out mileage claims or a central point to meet.
