How do I check my business broadband speed?

You can check your business broadband speed for free in about 30 seconds using CompareNet's browser-based UK speed test — no download, no sign-up. It measures your real download speed, upload speed and ping against Cloudflare's global network, then shows how your connection compares with typical UK business packages as of July 2026.

What your speed test results mean

What broadband speed does your UK business need?

Team sizeRecommended connection
1–5 staffFull Fibre (100–300 Mbps)
5–20 staffFull Fibre (300–500 Mbps)
20–50 staffLeased Line (500 Mbps–1 Gbps)
50+ staff / multi-siteLeased Line (1–10 Gbps)

How to get an accurate reading

For the truest line speed, connect your device to the router with an ethernet cable, close bandwidth-heavy apps, and run the test a few times at different points in the day. Wi-Fi is convenient but almost always slower than the line itself.

If your speed checker result came in below these ranges, your business is likely paying for performance it isn't getting. Compare business broadband deals or see whether a dedicated leased line makes sense for your team.

Broadband speed test FAQs

Is this broadband speed test free?
Yes — it's completely free with nothing to install and no sign-up. It runs in your browser and gives your real download, upload and ping in seconds.
Does it show my actual current speed like Google's speed test?
Yes. It measures the genuine live speed of the connection on the device you're using, exactly like searching "broadband speed test" on Google.
Why is my speed lower than what I pay for?
Usually Wi-Fi — walls, distance and other devices reduce speed. Connect by ethernet for the truest line reading.
What's the difference between a speed checker and a speed test?
They're the same thing — a broadband speed checker (or internet speed test) measures the live download speed, upload speed and ping of your current connection. Ours is tuned for UK businesses.
What is a good ping for business use?
Under 20ms is excellent, 20–50ms is good for VoIP and video meetings, and anything consistently above 100ms will cause noticeable lag. Leased lines typically deliver the lowest, most stable ping.
How often should I test my business broadband speed?
Test at least quarterly, and always before renewing your contract. Run it at your busiest time of day — if speed drops sharply when the whole team is online, your connection is congested.
