Electoral Commission Application Programming Interface (‘API’) Licence

Terms and conditions

1. About this Licence

The Electoral Commission (‘EC’) licenses Information under an Open Government Licence wherever possible. These Licence (‘the Licence’) terms and conditions are based on version 3.0 of the Open Government Licence, with specific amendments for the EC.

For example: Information that contains third party data that we only have permissions to release to certain people or with certain restrictions. We need to apply special conditions to protect use of personal data, where we would otherwise have to refuse a Licence.

The EC may at any time revise this Licence without notice. It is your responsibility to check the terms and conditions of this Licence.

All public EC API data (or 'open data') is freely released here for developers to use in their own software and services. We encourage software developers to use these feeds to present Information in innovative ways - providing they adhere to the API terms and conditions.
