Published by Pulse (SearchSwitchSave.com). Reviewed April 2026 by the UKSpeedTest editorial team led by Dr Alex J Martin-Smith.
Pulse currently measures download speed, latency, and jitter. If you need upload numbers, use your provider test or another reputable upload test, then compare results with your package details and daily use.
Who this page is for
Anyone working from home, sending large files, or troubleshooting video call quality.
Why upload matters
- Video calls and screen sharing send data upstream.
- Cloud backups can saturate upload and affect everyone in the home.
- Large outbound files need sustained upstream capacity.
How to test upload fairly
- Use Ethernet where possible.
- Pause backups and big downloads on other devices.
- Run more than one test at realistic times.
What to do next
Run Pulse speed test for download, latency, and jitter, then pair this with upload results from your provider. If upload remains too low for your needs, compare product options on BroadbandSwitch.uk.
Pulse measures download speed, latency, and jitter. Upload speed is not measured in the current release.

FAQ
Does Pulse include upload speed?
No. Pulse currently reports download speed, latency, and jitter in your browser. If you need upload numbers for video calls or cloud backups, use your provider upload test or another reputable upload test on a wired connection where possible, then compare with what your package says you should expect.
What is the quickest upload check?
The quickest meaningful check is your provider upload test on a laptop connected by Ethernet to your router, with backups and large downloads paused on other devices. One run gives a snapshot, but two runs at different times helps you see whether upload is stable or congested.
Can low upload hurt calls?
Yes. Video calls and screen sharing need steady upstream capacity. When upload is saturated, you can sound robotic, freeze, or drop even if download looks fine. If calls fail while downloads are active, pause heavy traffic and retest.
Should I switch package for upload only?
Test fairly first on a quiet line and a stable device setup. If upload still blocks your daily work after practical fixes, compare packages with stronger upload headroom and check switching steps that apply to your address and contract.
