Quick answer
How much internet speed do I need for IPTV?
Around 5 Mbps for SD, 15 Mbps for HD and 25 Mbps or more for 4K, per stream. Test the speed on the device you watch on, because Wi-Fi in another room can be much slower than your broadband package.
Your broadband speed decides how sharp and smooth your picture can be. Here is a practical guide for UK homes.
Recommended speeds
| Quality | Per stream | Two streams at once |
|---|---|---|
| SD | 5 Mbps | 10 Mbps |
| HD / Full HD | 15 Mbps | 30 Mbps |
| 4K | 25 Mbps | 50 Mbps |
Test on the right device
Run a speed test on the TV or streaming stick itself, not just your phone next to the router. Speeds in the living room can be a fraction of what your provider advertises, especially through walls.
UK broadband types
- ADSL (copper) – often 10 Mbps or less; fine for SD, borderline for HD.
- Fibre to the cabinet (FTTC) – typically 30–80 Mbps; good for HD and usually 4K.
- Full fibre (FTTP) and cable – 100 Mbps and up; comfortable for several 4K streams.
If your connection is slow
- Use an Ethernet cable – see Ethernet vs Wi-Fi.
- Stream in HD rather than 4K during busy evenings.
- Pause large downloads and game updates while you watch.
- Follow our tips on how to reduce buffering.

Frequently asked questions
Is my UK broadband fast enough?
Most fibre (FTTC), full-fibre (FTTP) and cable packages are. Older ADSL lines may only manage SD or HD. Ofcom’s checker shows the speeds available at your address.
