Upload scope for Pulse: Does UKSpeedTest measure upload speed?
Pulse measures download speed, latency, and jitter in your browser. It does not measure upload speed. For upload, use your provider’s tests or see our upload scope guide.

FAQ
Will full fibre fix upload?
Many full-fibre products offer higher upload than older copper-based services, but compare specific products.
How do I read my upload result safely?
Use your ISP or a reputable test, on Ethernet if possible, and compare to your product information.
Does turning off other uploads help calls?
Yes. Pause cloud backups and large outbound transfers during important calls.
Can Wi-Fi limit upload even if download looks fine?
Yes. Wi-Fi asymmetry and interference affect both directions.
Should I ask work for a symmetric line?
If your role uploads large files daily, discuss needs with IT and compare retail products that fit.
Does screen sharing increase upload demand?
Often yes, because you send more visual data. Expect more headroom use.
