Verification of taximeters in Ireland

NSAI Legal Metrology is responsible for the compliance of all taximeters in Ireland, which must be verified at all times.

Verification is conducted to ensure the accuracy of the taximeter and to provide confidence to consumers that the charges applied for taxi journeys are correct and accurate.

You need to verify your taximeter:

• When first purchased and installed in a registered taxi vehicle.
• Whenever a new fare is programmed into the taximeter, or whenever the existing programme is updated.
• Whenever any repair, alteration or adjustment is carried out on the taximeter or printer, which requires the security seal to be broken or removed.
• Whenever your taximeter is transferred to your new vehicle.

When a new fare is approved by the National Transport Authority (NTA), all taximeters require a fare programme update followed by verification.

On completion of a fare update, your installer will furnish you with a Taximeter Trader Information Form (TTI) by email. Please ensure that you have received an email containing the TTI form from your installer prior to your NSAI Legal Metrology appointment date, as the verification may not commence without proof of a TTI Form.

NSAI Legal Metrology regularly conducts inspections of taximeters to ensure active compliance in this sector.
