Every InstaMaps tool that takes UK postcodes, in one place: distances and drive times, the postcodes in a radius, the nearest branch to each customer, council and ward lookups, and flood and planning checks. Free, no account, and they all take a whole list.
Quick answer
For postcode to postcode distances by road, use the postcode distance calculator. For every postcode within a radius, the postcodes in radius tool. For each customer's nearest branch, the nearest location finder. For the council, ward, constituency and deprivation decile of a list, the bulk postcode lookup. Each one takes a single postcode or a whole spreadsheet.
Are these tools free?
Yes. Every one is free with no account. The list tools show the first 25 rows straight away and ask for a work email to run the rest.
Can I paste a whole spreadsheet of postcodes?
Yes. Each tool takes a pasted list or an uploaded spreadsheet or CSV, keeps your own columns and gives the file back with the answers added.
Do they work in Scotland, Wales and Northern Ireland?
The distance, route, radius, nearest-location and lookup tools work across the UK. The flood zone and planning checks are England's own data, so they cover England only, and the deprivation decile is England's index.
