The calling planner
The calculator runs in your browser. It uses the figures and destination you enter to produce a local comparison. It does not call a tariff feed, make calls, connect accounts or send the planner values to our server. The values are not saved between visits.
The “Add this brief” button copies the comparison into your enquiry field for review. It is sent only when you complete and submit the enquiry form.
Enquiry information
We request your name, email, enquiry type, service context and requirements to understand and respond to your enquiry. Company and phone are optional. Use a non-sensitive summary; do not send credentials, payment details, switching codes or confidential bills.
Essential security
The form uses an essential session cookie and security token. The web server may process an IP address, request time and other technical information for operation, security and rate limiting. This site has no advertising trackers or third-party analytics.

Your choices
You can use the planner without making an enquiry. For a request to explain, correct or discuss deletion of enquiry information no longer needed, use the enquiry form and choose “Other”.
