What Broadband Speed Do I Need?
Too slow and you get constant buffering. Too fast and you’re paying for speed you’ll never use. Here’s exactly how to work out what broadband speed your household actually needs.
In this guide
What does Mbps mean?
Broadband speed is measured in megabits per second (Mbps) or gigabits per second (Gbps). This measures how much data your connection can transfer every second — the higher the number the faster your broadband.
📶 1 Mbps — very basic. Enough for simple web browsing and email on one device.
📶 10 Mbps — fine for HD streaming on one device or light browsing on a few devices.
📶 30-60 Mbps — good for most households. Handles multiple devices and HD streaming comfortably.
📶 100+ Mbps — fast fibre. Great for busy households with lots of simultaneous streaming and gaming.
📶 500Mbps-1Gbps — ultrafast. Future-proof for even the most demanding households.
Download vs upload speed: Broadband speeds are usually quoted as download speeds — how fast data comes to you. Upload speed — how fast you send data — matters most for video calls and cloud backups. Most home broadband packages have lower upload than download speeds.
Recommended speed by household size
As a rough guide here’s what we recommend based on the number of people in your household:
Speed required by activity
Different online activities require different speeds. Here’s how much bandwidth each activity typically uses:
📧 Email and browsing — 1-5 Mbps per device
📱 Social media — 3-5 Mbps per device
📺 SD video streaming — 3 Mbps per stream
📺 HD video streaming — 5-8 Mbps per stream
📺 4K video streaming — 15-25 Mbps per stream
📹 Video calls (HD) — 3-5 Mbps upload and download
🎮 Online gaming — 3-25 Mbps depending on game
💻 Working from home — 10-25 Mbps recommended
⬇️ Large file downloads — the faster the better
What speed do I need for streaming?
Streaming services have minimum speed requirements for different quality levels. Here’s what the main platforms recommend:
Remember these are per stream — if two people are watching 4K Netflix simultaneously you need at least 30 Mbps just for that, plus extra for any other internet activity happening at the same time.
What speed do I need for gaming?
For online gaming raw speed is less important than you might think — most games only use 3-25 Mbps. What matters much more for gaming is latency (ping) — the time it takes for data to travel between your device and the game server.
Speed needed
Minimum 10 Mbps download for most games. 25+ Mbps recommended for smooth gaming alongside other household usage.
Latency (ping)
Under 30ms is ideal. 30-60ms is fine. Above 100ms you’ll notice lag. Full fibre broadband typically offers the lowest latency.
Game downloads are a different matter — a 100GB game update at 10 Mbps takes over 20 hours. At 100 Mbps the same download takes just over 2 hours. If you download games frequently faster broadband makes a real difference.
What speed do I need for working from home?
Working from home requirements depend on what you do but as a general guide:
💻 Basic office work — email, documents, web browsing: 10 Mbps
📹 Video calls (Zoom/Teams) — 5-10 Mbps upload AND download per call
☁️ Cloud-based work — uploading large files regularly: 50+ Mbps
🎥 Video editing or large file transfers — 100+ Mbps recommended
👨💼 Multiple people working from home — multiply requirements per person
Upload speed matters for WFH: Most broadband packages have much lower upload than download speeds. If you do frequent video calls or upload large files check the upload speed of any deal before signing up — not just the download speed.
