BT Speed Test

Test Your BT Broadband Speed (UK)

BT is one of the UK's largest broadband providers, offering ADSL, Fibre to the Cabinet (FTTC), and Full Fibre (FTTP) connections with speeds up to 900 Mbps. This test measures your actual BT download speed, upload speed and latency.

Tips to Improve Your BT Speed Test

BT Full Fibre (FTTP) plans offer much faster and more consistent speeds than FTTC — check if it's available at your address via BT's website.

Use the BT Smart Hub's ethernet ports for the most accurate speed test on Full Fibre plans.

FTTC speeds depend on the distance from your local street cabinet — homes further away get lower speeds.

Run the BT Speedtester from the My BT app, which checks against your specific line's sync speed.

If your Full Fibre speed is below plan, restart the ONT and Smart Hub, then contact BT if the issue persists.

BT Speed Test – FAQ

Common questions about bt speed test

What is the difference between BT Fibre and Full Fibre?

BT "Fibre" plans (FTTC) use fibre to the street cabinet but copper for the final stretch to your home, limiting speeds to around 36–67 Mbps. "Full Fibre" (FTTP) runs fibre directly to your home, enabling speeds from 150 Mbps up to 900 Mbps with much higher upload speeds.

Why is my BT upload speed much lower than download?

On FTTC and ADSL connections, upload speed is intentionally limited (asymmetric) — typically 20 Mbps or less. Full Fibre plans offer significantly higher upload speeds (around 100+ Mbps on the 900 Mbps plan), though still not fully symmetric.
