Welcome to the dedicated BT Speed Test tool. BT (British Telecommunications) is the largest internet provider in the United Kingdom, delivering Fibre Essential, Superfast Fibre, and Full Fibre (FTTP) up to 900 Mbps via the Openreach network. Test your UK broadband speed, ping, and line stability instantly.
BT Full Fibre (FTTP) delivers direct optical fiber to your home with options from Full Fibre 100 to Full Fibre 900 (900 Mbps down / 110 Mbps up). Older Superfast Fibre plans use FTTC (Fiber to the Cabinet) over copper phone lines, with speeds capped around 36 to 67 Mbps depending on your distance from the street cabinet.
BT Smart Hub routers provide robust whole-home wireless coverage. If your speed test shows slower results on Wi-Fi, ensure you are testing on the 5GHz band and that your BT Complete Wi-Fi Discs are positioned halfway between the Smart Hub and dead zones.
BT offers a Stay Fast Guarantee for broadband customers. If your speed test falls below your personalized guaranteed minimum, restart your BT Smart Hub, test with an Ethernet cable connected to the yellow LAN port, and run a line test via the My BT app.
Simply click the 'Start Test' button on this page. The tool will automatically measure your ping, download speed, and upload speed for your BT connection.
Compare your test results with the plan you purchased from BT. If your results are consistently much lower than your advertised plan, try restarting your router, connecting via Ethernet, or contacting BT customer support.
