2.5 Gbit/s is more than enough for 4K streaming, online gaming and working from home, even when several people are online at the same time. 10 Gbit/s is mainly useful for large file transfers.

Sky Fiber offers speeds of up to 2.5 Gbit/s for both downloads and uploads. That extra capacity can come in handy when a game update is downloading or files are being backed up to the cloud while others are online.

What can you do with a 2.5 Gbit/s connection?

With this fibre connection, you can:

• watch films, TV series and sport in 4K on several screens
• work from home, join video calls and share files
• play online and stream your gameplay live
• download large games and back up your videos to the cloud

1. What can your household do online at the same time with Sky Fiber?

4K streaming, video calls and online gaming can all run at the same time on one Sky Fiber connection.

• In this example, four 4K video streams and two Full HD video calls run while someone plays online on a PC or console. A game update, a large download or a cloud backup can add a short-lived spike in demand.
• That is when extra capacity is useful: it leaves more bandwidth for all the connected devices. Sky Fiber offers up to 2.5 Gbit/s for both downloads and uploads. This can help large transfers finish sooner while others in the household stream, work or play.

2. How long does it take to download a 10 GB file?

At a constant theoretical speed of 2.5 Gbit/s, it takes 32 seconds to download a 10 GB file.

In this theoretical example, switching from 1 to 2.5 Gbit/s saves you 48 seconds. Going from 2.5 to 10 Gbit/s saves a further 24 seconds. 10 Gbit/s is most useful if you regularly transfer very large files and your devices and the server can keep up.

✅ 2.5 Gbit/s already gives you plenty of capacity for all these activities at the same time.

What internet speed do you need for 4K streaming and video calls?

4K video streaming

Recommended speeds vary by service:

• Netflix recommends a stable connection of at least 15 Mbit/s for 4K. Four simultaneous streams therefore have a combined recommended speed of 60 Mbit/s.
• Sky Show and Sky Sport recommend a stable connection of at least 25 Mbit/s for UHD.

Full HD video calls

For a 1080p video call, Zoom recommends around 3 Mbit/s download and 3.8 Mbit/s upload.

Two simultaneous calls therefore have a combined recommended speed of around 6 Mbit/s download and 7.6 Mbit/s upload.

Why does Sky Fiber offer 2.5 Gbit/s instead of 10 Gbit/s?

Our approach: high-speed fibre broadband for everyday use at a fair price.

Moving from 2.5 to 10 Gbit/s does not automatically improve picture quality or make games more responsive. For online gaming, latency (the connection’s response time) and connection stability also matter. A higher maximum speed does not guarantee a lower ping.

10 Gbit/s can reduce transfer times for very large files, provided your devices and the servers involved can support that speed.

✅ With 2.5 Gbit/s, you already have plenty of capacity for the everyday activities described here, even when several people are online at once. We think this strikes the right balance between useful performance and a fair price.

What is a 2.5 Gbit/s upload speed useful for?

Download speeds let you receive data, for example when streaming a film or downloading a game. Upload speeds let you send data: sharing files, backing up photos and videos to the cloud, sending your video during a call or streaming your gameplay live.

Sky Fiber offers a symmetrical fibre connection with speeds of up to 2.5 Gbit/s in both directions.

Will all my devices get 2.5 Gbit/s, including over Wi-Fi?

Not necessarily. Your subscription speed is the maximum for your connection. Each device and each link in your home network also has its own limits.

Sky Fiber includes a Wi-Fi 7 router with 2.5 Gbit/s WAN/LAN ports. Wi-Fi performance also depends on device compatibility, distance from the router, walls and interference.

To get close to the maximum speed on a computer, connect over Ethernet. The router port, the computer's network card and the cable must all support 2.5 Gbit/s. A 1 Gbit/s port limits that device to 1 Gbit/s, even with a 10 Gbit/s subscription.
