Direct answer: most UK homes need far less than they are sold. As a rough guide, light users are fine on 30 to 75 Mbps, a typical family with some 4K lands around 150 to 250 Mbps, and only very busy homes with several 4K streams and heavy uploads need 500 Mbps or more. The calculator below turns how you actually use the internet into a recommended tier, then you can compare deals at that speed by postcode.

A quick reference for what each UK speed tier comfortably handles.
The short version
- Speed is about simultaneous use. What matters is how much is happening at once at peak, not everything you ever do in a day (BroadbandSwitch.uk, 2026).
- 4K is the big driver. Plan around 25 Mbps per 4K stream and 5 Mbps per HD stream, so two 4K streams alone need about 50 Mbps before anything else (Netflix, n.d.; Disney+, n.d.).
- Upload matters more than people expect. Video calls and cloud cameras use upload, and many part-fibre plans have low upload, so full fibre helps if you call or back up a lot (Zoom, n.d.; Microsoft, 2024).
- Leave headroom. Add roughly a third above your peak so speeds hold up when everyone is online (BroadbandSwitch.uk, 2026).
- Do not overpay. Gigabit is genuine headroom for very busy homes, but most families are well served below 300 Mbps (BroadbandSwitch.uk, 2026).
How much speed each activity uses
These are the planning figures behind the calculator, taken from each service's own guidance.
| Activity | Plan for | Direction | Source |
|---|---|---|---|
| 4K (Ultra HD) stream | ~25 Mbps | Download | Disney+; Netflix states 15, YouTube 20 |
| HD (1080p) stream | ~5 Mbps | Download | Netflix |
| HD video call (Zoom, Teams, Meet) | ~4 Mbps | Each way | Zoom; Google; Microsoft |
| Cloud gaming (GeForce Now, Xbox Cloud) | ~22 Mbps (1080p), ~45 Mbps (4K) | Download | NVIDIA; Microsoft |
| Console or PC gaming (live play) | Low; latency matters more | Download | General guidance |
| Cloud security camera (1080p) | ~2 Mbps each | Upload | Google Nest |
| Ofcom decent broadband minimum | 10 / 1 Mbps | Both | Ofcom |
The calculator adds your simultaneous demand, applies roughly a third headroom, and matches the total to a UK speed tier. Amounts are planning guidance and change as services update their apps.
Download and upload are not the same
Most people buy on the download number and never look at upload. That is fine until you start making video calls, running cloud cameras or backing up photos, all of which send data the other way. Many part-fibre plans give generous download but modest upload, so a home that calls and backs up a lot can feel slow even on a big headline speed.
Is your current line keeping up?
Test what you actually get, then compare
A recommendation only helps if your line delivers. Check your real-world speed with Pulse, our free UK speed test, ideally over a wired connection so you see the true line speed rather than your Wi-Fi. You can also run the speed test on this site. If you are paying for far more than you receive, that is a reason to switch.

Run a speed test Download time calculator Live quality monitorHow we calculate your recommendation
We add up your peak simultaneous demand using published planning figures: about 25 Mbps per 4K stream, 5 Mbps per HD stream, about 4 Mbps each way per HD video call, about 2 Mbps upload per cloud camera, and the services' own numbers for cloud gaming, plus a small allowance for background smart devices. We add roughly a third for headroom, then match the total to a UK speed tier. Upload is treated separately, because many part-fibre plans have far lower upload than download, so a home with several cameras or daily backups may need full fibre even at a modest download tier. It is guidance, not a guarantee: your line technology and your Wi-Fi also shape what you experience. For the difference between technologies, see our full fibre versus part fibre guide.
Frequently asked questions
How much broadband speed do I actually need?
It depends how many people and devices are active at the same time. Light use (1 to 2 people) often fits 30 to 75 Mbps. A typical family (3 to 4 people) with some 4K and a video call usually lands around 150 to 250 Mbps. Very busy homes with several 4K streams and heavy uploads benefit from 300 Mbps or more. Use the calculator above for a figure based on your own use.
Is 100 Mbps enough for a family in the UK?
For many families of 2 to 4 with HD streaming, browsing and the odd video call, 100 Mbps is comfortable. Once you add several 4K streams at once, or heavy uploads, 150 to 300 Mbps is a better fit. The calculator will show which side of that line your household sits on.
What is a good broadband speed in the UK?
A good speed is simply one that covers your peak use with headroom to spare. For most homes that is somewhere between 75 and 250 Mbps. Buy for how you actually use the internet rather than the biggest headline number, because speed you never use is money wasted.
Do I need gigabit (1000 Mbps) broadband?
Most UK homes do not. Gigabit is genuine headroom for very busy households with many devices, multiple 4K streams and heavy uploads at once. Plenty of families are well served below 300 Mbps, so buy for your real use rather than the headline number.
What is the difference between download and upload speed?
Download is data coming to you, such as streaming, browsing and game downloads. Upload is data leaving you, such as video calls, security cameras, cloud backups and sending files. Most plans give far more download than upload, so if you call or back up a lot, check the upload figure and consider full fibre.
What speed do I need for 4K streaming?
Plan for about 25 Mbps per 4K stream to leave headroom. Netflix recommends 15 Mbps for Ultra HD, YouTube about 20 Mbps and Disney+ about 25 Mbps (Netflix, n.d.; Google, n.d.; Disney+, n.d.). Two 4K streams plus other use typically needs 150 Mbps or more.
What upload speed do I need for video calls?
Aim for at least 15 to 25 Mbps upload if more than one person calls at once. A single 1080p Zoom call uses about 3.8 Mbps upload, Google Meet up to about 3.6 Mbps each way, and Microsoft Teams about 1.5 Mbps for a one-to-one call (Zoom, n.d.; Google, n.d.; Microsoft, 2024). Many part-fibre plans have low upload, so full fibre helps.
Does broadband speed affect gaming?
For live play, not much. Online games use very little bandwidth; what matters is latency, the delay between your console and the server, often shown as ping. Higher speed mainly means game downloads and updates finish faster. A stable, low-latency connection beats a huge headline speed for gaming.
How much speed do I need for 8K streaming?
Plan for roughly 50 Mbps per 8K stream, though 8K content is still rare and most homes will not use it for years. If you do have an 8K TV and source, treat it like two 4K streams when sizing your line.
Why is my Wi-Fi slower than my broadband speed?
Your package speed is the line into your home; Wi-Fi is the wireless link to your devices, and walls, distance and older devices all reduce it. Test over a wired connection to see the true line speed. If that is fine, the bottleneck is Wi-Fi, and a faster package will not fix it.
Does the number of devices affect the speed I need?
Yes, but mostly through what they are doing. A phone left idle uses almost nothing, while a phone streaming 4K uses a lot. Many idle smart devices add a little background load each, which adds up in a big home, so the calculator includes an allowance for them.
What broadband speed do I need for working from home?
For video calls and normal cloud apps, 30 to 50 Mbps download and 10 to 20 Mbps upload is usually enough for one person. Add more if you share the line with streaming or run large uploads and backups. The calculator accounts for calls, uploads and everyone else in the house at the same time.
