BT Speed Test - Test Your BT Internet Speed | Fiber & Mobile

Speeds depend on your plan, address, and connection type. Run multiple speed tests to compare download, upload, and latency against your advertised tier. Test on a wired connection when possible and repeat during peak hours to see real-world performance.

Click Start Test to measure download, upload, and ping. For best accuracy, close other apps, pause large downloads, and test on Ethernet if possible. Repeat the test at different times to capture congestion patterns.

Slowdowns can be caused by network congestion, Wi-Fi interference, outdated equipment, or distance from the router. Try rebooting your modem, using a wired connection, and testing closer to the router to isolate the issue.

Yes. BT offers fiber in select areas, and availability depends on address and network build-out. Check eligibility, then run a speed test after installation to confirm actual throughput and uploads.

Place your router centrally, avoid obstructions, and use 5 GHz or Wi-Fi 6 when available. Update firmware, limit device congestion, and consider a mesh system for larger homes.

The right tier depends on household size and usage. Basic browsing and HD streaming can work on entry plans, while 4K streaming, gaming, and multiple users benefit from higher tiers. Use your speed test results to verify the tier meets your needs.

Compare download, upload, and latency with your plan and usage needs. Download affects streaming and browsing, upload affects video calls and backups, and latency affects gaming. If results are lower than expected, test on Ethernet and repeat during off-peak hours.

If BT includes mobile service, test outdoors and indoors to compare signal strength. Results can vary by tower load, device, and coverage.
