When your office depends on Microsoft 365, Teams, VoIP or cloud backups, a slow or unreliable internet connection isn’t just frustrating — it’s expensive.
Choosing the right connectivity — leased line, business fibre, or SoGEA — can save money, boost productivity and reduce downtime.
This guide explains the differences, pros and cons, and how to decide which connection fits your business best.
In short:
If uptime, video calls, and cloud access are critical — go Leased Line.
If budget matters more — choose Business Fibre or SoGEA.
| Feature | Leased Line | Business Fibre (FTTC/FTTP) | SoGEA |
| Connection Type | Dedicated line for your business only | Shared fibre connection | Single-order fibre broadband (no phone line) |
| Speed | Symmetrical (same upload & download) | Asymmetrical (fast download, slower upload) | Similar to FTTC |
| Reliability | Guaranteed uptime (SLA-backed) | Best-effort service | Best-effort but newer network |
| Support | 4-hour fix | Next-business-day fix | Next-business-day fix |
| Typical Cost (monthly) | £250–£800 | £40–£100 | £35–£70 |
A leased line is a dedicated, uncontended connection between your office and your ISP.
You don’t share bandwidth — so your upload and download speeds are always the same, 24/7.
Ideal for:
Advantages:
✅ Symmetrical speeds (100Mb–10Gb)
✅ Enterprise-grade SLAs (4-hour fix)
✅ No slowdowns at peak times
✅ Supports VPN, video, remote work
Disadvantages:
❌ Higher monthly cost
❌ Installation can take 60–90 days
Business Fibre (FTTC or FTTP) is shared broadband using Openreach infrastructure.
It’s fast, affordable, and widely available — a great option for smaller teams.
Ideal for:
Advantages:
✅ Lower cost
✅ Easy installation
✅ Speeds up to 1Gb/s (FTTP)
Disadvantages:
❌ Shared bandwidth (can slow down at busy times)
❌ Upload speeds limited
❌ SLAs less robust than leased lines
SoGEA (Single Order Generic Ethernet Access) is the UK’s next-generation broadband designed for the PSTN switch-off (2025).
It provides fibre broadband without needing a traditional phone line — ideal for VoIP setups.
Ideal for:
Advantages:
✅ No phone line required
✅ Lower monthly cost
✅ Compatible with cloud VoIP and Teams Phone
Disadvantages:
❌ Speed limited to FTTC levels
❌ No symmetrical bandwidth
❌ Next-business-day fix SLA
| Office Size | Best Option | Why |
| 10–30 users | SoGEA or Business Fibre | Affordable, simple, fast enough for Teams & cloud |
| 30–80 users | Business Fibre or Entry Leased Line | Balance of speed and cost |
| 80–200 users | Leased Line | Guaranteed performance for VoIP and cloud workloads |
| Connection Type | Typical Monthly Cost | Install Time | Best For |
| Leased Line | £250–£800 | 60–90 days | Large or multi-site offices |
| Business Fibre (FTTC/FTTP) | £40–£100 | 7–14 days | Small to mid-sized offices |
| SoGEA | £35–£70 | 7–14 days | Small offices or VoIP-only setups |

Q1. What’s the main difference between a leased line and business fibre?
A leased line is a dedicated, uncontended connection with guaranteed speeds and uptime.
Business fibre is shared with other users, so speeds can vary depending on demand.
Q2. Is SoGEA better than business fibre?
Not necessarily. SoGEA removes the need for a phone line, making it simpler and often cheaper.
Performance is similar to FTTC business fibre, but FTTP fibre can be faster if available.
Q3. Do I need a leased line for my office?
If your business can’t afford downtime — yes.
Leased lines provide symmetrical speeds, guaranteed SLAs, and reliability for cloud-first offices.
Q4. How fast is SoGEA broadband?
Typical SoGEA speeds are 80Mb download / 20Mb upload, depending on distance from the cabinet and provider.
Q5. Can I have both a leased line and SoGEA?
Yes — many businesses use SoGEA as a backup connection for failover and redundancy.
Q6. What happens to broadband after the PSTN switch-off in 2025?
All UK broadband lines will move to digital-only (IP) connections such as SoGEA.
Traditional phone lines will be discontinued.
Q7. How do I check which connections are available at my address?
Contact Amazing Support — we’ll run a line availability check and show all leased line, FTTP and SoGEA options for your postcode.
