MapIt: UK

Usage and licensing

This service is free of charge for non-profit low volume use. ‘Non-profit low volume use’ means use by registered UK charities or individuals working unpaid on a non-profit project, and that does not exceed 50,000 calls a year. Please attribute us with the text “Powered by Mapit” and a link back to the MapIt front page. If you are using the API for a charitable purpose and are unsure of the likely volume please contact us in advance by emailing enquiries@mysociety.org.

All other users need to get a licence. We have a range of pricing options depending on the volumes you expect. Our licences cover 12 months, and we offer discounts to charities. Please email us on enquiries@mysociety.org with details of your expected volumes, and we will let you know the costs.

Rate limiting

The standard paid service is limited to an average of 1 call per second in a rolling 3 minute period. If you need more than this, we can set you up a dedicated service. Please get in touch.

Self-installed versions of MapIt

Some organisations prefer to install their own internal version on MapIt. We are happy to help with this. Depending on your needs, we can advise your technical team on how to do this, or our developers can install it for you.

One-off data range searches

We also offer one-off look-ups for large data sets – this is useful when you don’t need to use the API but simply have data that you need matched (e.g. a list of postcodes to match to the constituencies they fall into). We can do this for you quickly and easily.

Geometry files

If you need to use the API to download the MapIt geometry files, you can do so for free for up to 50,000 files if you are a registered UK charity or an individual working on a non-profit project. If you are not, or need more than 50,000 files, we can licence them to you.

For all enquiries about licensing, please drop us a line with some information about what you’re looking to do, and we’ll get in touch to discuss how we can help you.
