What NetStartr measures for United Kingdom users
Click the button above and we measure download speed, upload speed, ping, jitter and packet loss in roughly 20 seconds. We benchmark against the United Kingdom averages (95 / 25 / 18 ms) so you can immediately tell whether your line is performing as expected for your country or state.
The test runs entirely in your browser using Cloudflare\'s global edge — no signup, no app install, no data sold. After the test, we tell you what your connection is good for (4K streaming, gaming, calls) and how much of your ISP\'s advertised plan you\'re actually getting.
Get accurate results
- Test from a wired Ethernet connection if possible.

- Test at peak (evening) and off-peak (morning) to spot ISP congestion.
