Sky Fibre Speed Test: Check Your Speed (2026)

Sky broadband delivers average speeds of 67 Mbps on Superfast (part-fibre), 150 Mbps on Full Fibre 150, 500 Mbps on Full Fibre 500, and 900 Mbps on Gigafast. To test your actual Sky speed, use an independent tool like Ookla Speedtest over an ethernet connection. If speeds are consistently below Sky's minimum guaranteed level, you may be able to leave your contract without penalty under Ofcom's rules.

How to Test Your Sky Broadband Speed

Connect your laptop or computer directly to the Sky router via ethernet cable — Wi-Fi speeds are always lower than your line speed due to interference. Visit speedtest.net or fast.com and run three tests at different times: morning, afternoon, and evening (8–10pm is peak). Compare your results against Sky's advertised averages: Superfast 35 at 35 Mbps, Superfast at 67 Mbps, Full Fibre 75 at 75 Mbps, Full Fibre 150 at 150 Mbps, Full Fibre 500 at 500 Mbps, and Gigafast at 900 Mbps. Sky also offers Full Fibre 2.5 Gigafast+ at 2,500 Mbps and Full Fibre 5 Gigafast+ at 5,000 Mbps in limited areas.

Sky Broadband Speeds and Packages (March 2026)

Sky runs on the Openreach network, meaning its coverage and maximum speeds mirror BT, EE, and TalkTalk in any given area.

Why Your Sky Speed Might Be Slow

Part-fibre connections lose speed over distance — the further your home from the green street cabinet, the slower your connection. Thick walls, floor changes, and electronic interference reduce Wi-Fi range. Sky's router (Sky Broadband Hub) supports Wi-Fi 5, which is a generation behind competitors using Wi-Fi 6. You can add Sky Broadband Boost (£5/month) for a Wi-Fi guarantee and faster fixes, or purchase a third-party Wi-Fi 6 mesh system. If your ethernet speed test shows good results but Wi-Fi is poor, the issue is wireless coverage, not your broadband line.

Frequently Asked Questions

What is Sky's minimum guaranteed speed?

Sky provides a minimum speed guarantee on all packages. If your speed drops below this floor for 30 consecutive days after reporting, Sky will let you leave your contract without penalty or offer a fix. The exact minimum varies by address and package.

Is Sky broadband fast enough for 4K streaming?

4K streaming requires around 25 Mbps per device. Sky Superfast at 67 Mbps can handle 2 simultaneous 4K streams. For households with 3+ people streaming or gaming at once, Full Fibre 150 or above is recommended.

Does Sky offer Wi-Fi 6?

Sky's standard router uses Wi-Fi 5. You can upgrade to the Sky WiFi Max mesh system for better coverage, but it's an extra monthly cost. Many altnet providers include Wi-Fi 6 routers as standard with their packages.
