What is business broadband?

Business broadband is designed specifically for commercial use. It often includes higher reliability guarantees, faster fault repair times, dedicated customer support, static IP options, and Service Level Agreements (SLAs). It typically costs more than residential but offers stronger protections.

For home‑based sole traders, residential fibre may be enough. For VAT‑registered businesses or offices, business broadband is usually more appropriate.

What speed does your business need?

100–150 Mbps
sole trader / home

Video calls, cloud tools, email, file uploads.

150–300 Mbps
small office (3–10)

Multiple video calls, cloud software, file sharing, payment systems.

300–500 Mbps+
growing (10+)

Heavy cloud, VoIP, large transfers, frequent conferencing.

500 Mbps–1 Gbps
enterprise / high‑demand

Large teams, data‑heavy, hosting, dedicated operations.

Why upload speed matters for business

Cloud backups, sending large client files, hosting servers, video conferencing, VoIP phone systems — all depend on upload.
Standard fibre upload: 10–20 Mbps   Full fibre upload: 100–900 Mbps
For modern businesses, full fibre offers a major advantage.

Service Level Agreements (SLAs) explained

An SLA defines guaranteed uptime, maximum repair time, and compensation if targets aren’t met. Typical residential repair: 2–5 working days. Typical business SLA: fix within 24–48 hours. For businesses that rely on connectivity, this matters.

Contract length options

Business broadband contracts typically run 12, 24 or 36 months. Longer often means lower monthly rates — but less flexibility. Always compare monthly cost, setup fees, early termination terms.

Typical business broadband pricing

SpeedMonthly cost (typical)
100 Mbps£30–£40
300 Mbps£40–£55
500 Mbps£50–£65
1 Gbps£60–£80+

Prices vary by postcode and infrastructure availability.

Dedicated vs shared connections

Most business broadband is shared (like residential) but with higher priority. Dedicated leased lines offer guaranteed symmetrical speeds, exclusive connection, much higher cost (£200+ per month) — suitable for larger enterprises.

🧑‍💻 When residential broadband may be enough

If you’re a sole trader, work from home, don’t need an SLA, and downtime risk is manageable — residential full fibre (e.g. 150 Mbps) is often cheaper than entry‑level business packages.

How much could you save?

If you’re paying £65/month for 100 Mbps business broadband and new deals offer £45/month for 300 Mbps: save £20/month, improve performance and upload speed. Businesses often stay on legacy contracts too long.
