These are the lowest figures each provider publishes, so the 6 and 12 month totals are a floor, not a quote. They add the install fee, the monthly lease, calibration visits and removal where published. An asterisk means a fee is not published and is not included. Per day rates are counted as 30 days a month.

Reported totals usually run two to three times the published floor. Calibration visits, device protection, data fees and missed-appointment charges are rarely in the headline price.
