What are the actual download and upload speeds for BT Full Fibre 900?

The package offers an average download speed of 900Mbps and an average upload speed of 110Mbps. Because this is a Fibre-to-the-Premises (FTTP) connection, these speeds are highly consistent; real-world testing in 2026 has shown peak download speeds can reach up to 925Mbps with exceptionally low latency of approximately 6.9ms.

Which router is included with BT Full Fibre 900?

New customers receive the BT Smart Hub 2. While it is a powerful Wi-Fi 5 router featuring seven internal antennae and smart channel selection, it does not support Wi-Fi 6. For those in larger homes, it is compatible with BT Complete Wi-Fi discs to ensure a signal in every room.

Is BT Full Fibre 900 good for competitive gaming?

Yes, it is one of the best national packages for gaming due to its FTTP infrastructure, which provides a more stable connection than traditional copper-based fibre. The low 6.9ms latency (ping) and high bandwidth allow multiple users in a single household to game, stream in 4K, and download large updates simultaneously without lag.

Does this package require a traditional phone line?

No, BT Full Fibre 900 is a "data-only" broadband service and does not require a traditional analogue phone line. If you still require a home phone, you can opt for an "Advanced Digital Home Phone," which uses Digital Voice (VoIP) technology to route calls over your internet connection instead of the old copper network.
