Most small businesses (under 20 staff) need at least 50–100Mbps of dedicated, reliable bandwidth. Larger businesses, those running VoIP, CCTV or cloud-heavy applications, or those with multiple simultaneous users, need 100Mbps to 1Gbps — ideally on a leased line with a symmetric SLA.
To work out what you need, add up the bandwidth used by all your applications running simultaneously:

Standard FTTC (fibre to the cabinet) broadband typically gives you fast download but slow upload — sometimes as low as 10–20Mbps upload on a 80Mbps package. For businesses that:
...slow upload speeds are the real bottleneck. Full fibre (FTTP) and leased lines both offer much better upload speeds. Leased lines give symmetric speeds — same upload as download — which is the gold standard for business use.
Standard business broadband is contended — meaning multiple businesses share the same physical connection. At peak times (9–11am, lunchtime), speeds can drop significantly. A leased line is uncontended — the bandwidth is yours alone, 24 hours a day.
For most offices, contended FTTP is fine. For businesses where connectivity is business-critical — law firms, medical practices, financial services, logistics operations — uncontended leased line is the right choice.
| Application | Bandwidth per user/device | Notes |
|---|---|---|
| VoIP phone call | 100kbps per call | Both up and down |
| HD video call (Teams/Zoom) | 1.5–3Mbps per participant | Uses significant upload too |
| CCTV camera | 1–4Mbps per camera | Higher for 4K |
| General web browsing | 1–5Mbps per user | Bursty, not constant |
| Cloud apps (CRM, ERP) | 2–10Mbps per user | Depends on data volume |
| Large file uploads | 5–50Mbps | Needs symmetric connection |
| EPOS / card terminals | 0.5–1Mbps per terminal | Low but critical |
| Streaming (training/media) | 5–15Mbps per stream | Avoid on shared lines |
