Average internet speed in London
London's fibre rollout has reached most postcodes, and Virgin Media's hybrid network still gives the fastest option on some streets. Upload throughput is the number most UK providers advertise least.
These are regional benchmarks for fixed-line broadband, not a guarantee of the speed at your specific address. Your own result from the test above is the number that counts.

What speed do you need in London?
The households in London that feel their connection is slow are usually paying for more bandwidth than their line can deliver. These are the tiers that matter in practice:
- 25 Mbps / 5 Mbps — browsing, email, HD video calls for one household. The floor most providers consider adequate.
- 100 Mbps / 20 Mbps — 4K streaming on several screens, large file transfers, and working from home with frequent video meetings.
- 300 Mbps and above — multiple simultaneous 4K streams, cloud backups, and gaming alongside heavy streaming.
- Upload speed — worth more than most people expect if you back up photos, host calls or push large files to the cloud.

How do I get faster internet in London?
Around 72% of premises in London can get fibre. If you are on copper DSL or a slower shared cable segment, upgrading to fibre usually gives the biggest single jump. Otherwise, a wired Ethernet connection, a newer router and pausing other downloads during the test will make your measured speed match your plan more closely.
How to get a more accurate London result
A measurement is only as good as the setup behind it. To get a number that reflects your plan rather than your Wi-Fi:
- Connect over Ethernet rather than Wi-Fi where you can.
- Pause every other download, cloud backup and video stream on the network.
- Keep the browser tab in the foreground — background tabs are throttled by most browsers.
- Close VPNs and proxies, which add overhead to every request.
- Run the test twice and compare; the two runs should be close.
