For anyone in the UK is interested in this type of data:<p><a href="https:&#x2F;&#x2F;www.ordnancesurvey.co.uk&#x2F;business-and-government&#x2F;products&#x2F;code-point-open.html" rel="nofollow">https:&#x2F;&#x2F;www.ordnancesurvey.co.uk&#x2F;business-and-government&#x2F;pro...</a><p>The data is free, but it&#x27;s in Easting&#x2F;Northing format rather than Latitude&#x2F;Longitude. I would recommend converting it to Latitude&#x2F;Longitude using the WGS84 projection (if that means nothing to you, basically it means you&#x27;re using the standard format for coordinate data used in websites, can use the data with Google Maps, OSM, etc...).
