Cable company UPC reached one million subscribers in Ireland for the first time last week.

Full year results published by the company show that the number of subscribers it signed up grew by 11% over the year to reach 988,700 by the end of December.

This figure hit the key one million mark last week.

UPC said it has 304,300 broadband customers, up 18% year on year. Its growth in home phone customers jumped 46% to 238,000, while it also had 382,200 digital television subscribers by the end of the year.

The company has invested over €500m as part of the rollout of its new fibre powered network across Ireland. It said it now offers 150 Mpbs broadband speeds to 40% of all Irish homes.

Highlights of the year included the launch of its on-demand service and the overhaul of its HD service to include more than 23 channels.

''We had a very big and busy year in 2012. Reaching 1,000,000 subscriptions is the culmination of the great work of our 800 employees and 700 contractors,'' commented Dana Strong, chief executive of UPC Ireland.

She said that the the results demonstrate the underlying strength and appeal of its business model in a fast-changing market.

Ms Strong said that research shows UPC customers spend more time online, use more devices and are more satisfied than other broadband customers.
