How much speed you need
These figures are per stream, measured on the device you watch on. If two people watch at once, add their figures together, or let the IPTV bandwidth calculator add them up for your household. Other calculators and converters are in IPTV tools.
| Picture quality | Recommended speed | Suits |
|---|---|---|
| HD (720p) | 5 Mbps | Phones and small screens |
| Full HD (1080p) | 10 Mbps | Most TVs and most live channels |
| 4K UHD | 25 Mbps | 4K TVs with a 4K device |
| 8K UHD | 50 Mbps | 8K TVs only |
Players adjust the quality automatically. On a slower connection you’ll see a slightly softer picture rather than constant freezing, but the recommended speeds give you a consistently sharp, stable image.
Test the speed properly
A speed test on your phone standing next to the router tells you almost nothing about what your TV receives. For an accurate picture:
- Test on the TV device itself. Install a speed-test app from your device’s app store (many are free), or use the network check in its settings.
- Test in the evening, between 7pm and 10pm, when home and neighbourhood networks are busiest.
- Test twice, a few minutes apart, and note the lower result.
If the result is well below your broadband package, the loss is happening inside your home, usually over Wi-Fi.
Improve your Wi-Fi
In rough order of how much they help:
- Use an Ethernet cable for the main TV. It’s the most reliable fix there is. Fire TV Sticks need Amazon’s Ethernet adapter; most boxes and Smart TVs have a port built in. See Ethernet ports and adapters by device.
- Use the 5 GHz network. It’s much faster than 2.4 GHz over short distances and far less crowded, especially in flats. See Wi-Fi bands for IPTV.
- Move the router into the open, high up and away from the TV’s metal back, not inside a cupboard.
- Use the HDMI extender so a stick isn’t hidden behind the TV.
- Add a mesh point or powerline adapter near the TV if it’s far from the router.
- Update the router, or ask your broadband provider for a newer one. Old routers struggle with several streams at once.
UK broadband types and IPTV
| Broadband type | Typical suitability |
|---|---|
| Full fibre (FTTP) | Excellent for several 4K streams |
| Cable | Excellent |
| Part fibre (FTTC / “superfast”) | Usually good; check the evening speed on long lines |
| 5G home broadband | Usually good; depends on signal |
| 4G home broadband | HD is fine; speeds vary through the day |
| Standard ADSL copper | May manage one HD stream; 4K unlikely |
Several screens at once
Add up what every device in your home needs at your busiest time. For example, a 4K TV (25 Mbps), a Full HD bedroom TV (10 Mbps) and a phone in HD (5 Mbps) need about 40 Mbps, plus whatever else the household is doing. Remember that each simultaneous stream also needs its own connection on your plan; see screens and connections.
