Excessive use is currently determined as over 100,000 calculator loads per month/per domain.


Basic support is provided in order to get your widget working on your website, subject to us being provided with appropriate information (including at times access details) to do this. Any additions, customisations or changes to the codebase are not provided under basic level support.

For HTML widgets, we will notify you via email when there is an update to a widget’s code, this could be because third party data (eg, HMRC stamp duty rates) have changed and therefore updated code would be needed.

For WordPress plugins, you will receive a notification in your WordPress admin’s updates page when there is an update available for the plugin.

For hosted widgets, the updates will automatically be applied when necessary.
