One of the largest telecom company in the world, British Telecom (BT) has announced that it will be announcing a program as per which its customers will be given an option to upgrade to Fibre broadband service, free of charge.

But the option will be available only for the customers who use bundle broadband, phoneline and call services. This means Option 2 and 3 users are going to be provided with the upgrade. For the Option 1 users, the upgrading can be done with a minimal charge.

The fibre broadband service is called 'BT Infinity' and it offers up to 40 Mbps of download speed and upload speed of around 10 Mbps. BT also said that the service will be made available around two third of UK by 2015.

It is estimated that once the service is made available in the area that BT claims, charges for fibre broadband will come down to £7.49 (excluding line rental) per month on the 3 months. This will be for the Option 1 customers. They will be given a speed of 2Mbps and the Option 2 customers will be given speed of 10 Mbps.
