⬇️ 100–1000 Mbps
⬆️ 100–900 Mbps upload
Lower latency, stable at peak hours – strongly recommended.

For small offices relying on cloud systems, business fibre is usually recommended.

SLA (Service Level Agreement)

Most business broadband includes 24–48h repair targets, uptime guarantees (≥99.5%), and defined escalation – valuable when downtime hurts operations.

Typical pricing (excl. VAT)
100 Mbps£30–40/mo
300 Mbps£40–55/mo
500 Mbps£50–65/mo
When to consider a leased line

If internet is mission‑critical, downtime causes financial loss, you host services – leased lines offer guaranteed speeds, but from £200+/mo. Usually unnecessary for small offices.

How to keep costs low
1️⃣ Choose the right speed – don't overbuy gigabit.
2️⃣ Compare contract lengths (24‑month often best value).
3️⃣ Review total cost: VAT, setup fees, static IP add‑ons.
4️⃣ Check infrastructure – full fibre may be similar price.
Example saving: Old £70/mo for 100 Mbps → new deal £48/mo for 300 Mbps = save £22/month (£264/year) + better performance.
Best setup for different small offices
2‑person consultancy → 100–150 Mbps full fibre
5‑person agency → 300 Mbps full fibre
Tech startup (8 staff) → 300–500 Mbps
Retail office with POS → 150–300 Mbps + SLA
