Quarterly Key Data Report Q3 2025

1. Background

ComReg collects statistical data from authorised operators on a quarterly basis. Not all such operators are included in this data collection (based on minimum revenue levels), but ComReg aims to represent 95% of the total markets. This data includes information on subscriptions, lines, revenues, broadband speeds, minutes and data usage for both fixed and mobile voice and broadband. The data and charts included below are a subset of the information collected. The detailed presentations of data are available on the ComReg data portal.

Map visualisations for ‘FTTP’ and ‘Gigabit’ Coverage and Take-Up statistics by County, Local Electoral Area, Electoral Division and other Geographic units can be found at ComReg’s Open Data Map Hub.

Data presented in this Summary of the Quarterly Key Data is based on questionnaires completed by certain authorised operators for the period from 1^st April 2025 to 30^th June 2025. The report is based on submissions from 54 active operators.
