Choosing the right broadband connection for your business can make a significant impact on performance, reliability, and growth.
As we step further into 2025, the options available have expanded and improved. But with more choice comes more complexity. Should your business go with FTTP, G-Fast, or invest in a Leased Line?
In this guide, we break down each option, compare the pros and cons, and help you decide which is the best fit for your business.
FTTP (Fibre to the Premises)
FTTP delivers full-fibre connectivity directly to your building. It offers ultra-fast, reliable speeds ideal for businesses that rely heavily on cloud applications, video conferencing, and large data transfers.
Typical Speeds: Up to 1 Gbps download / 220 Mbps upload
Reliability: High
Availability: Increasing across the UK, especially in urban areas
Pros:
- Excellent speed and reliability
- Future-proof for business growth
- Supports multiple users with no performance drop
Cons:
- Installation can take longer
- Not available in all areas yet
Best for: SMEs, growing businesses, and teams needing high-speed uploads/downloads.
What is G-Fast?
G-Fast is an upgrade to existing FTTC (Fibre to the Cabinet) infrastructure. It increases download speeds without the need for full-fibre installation. Previously the only way to get faster broadband speeds was to install a Fibre to the Property (FTTP) connection (unavailable in all areas). This where G Fast comes in.
Typical Speeds: Up to 300 Mbps download / 50 Mbps upload
Reliability: Medium to High
Availability: Limited to areas with compatible cabinet infrastructure
Pros:
- Faster than standard FTTC
- Quick and simple upgrade
- More affordable than FTTP or Leased Lines
Cons:
- Performance varies with distance from cabinet
- Lower upload speeds than FTTP or Leased Lines
Best for: Smaller offices with moderate usage and existing FTTC setups.
Pros:
- Guaranteed bandwidth and performance
- Symmetrical speeds for cloud, VoIP, and video calls
- High-grade support and SLAs
Cons:
- Higher cost
- Longer setup time
Best for: Large businesses, data-heavy organisations, and mission-critical operations.
Leased Line
A Leased Line is a dedicated, private connection between your premises and the internet. It's symmetrical, so upload and download speeds are the same, and it's not shared with other users.
Typical Speeds: From 100 Mbps up to 10 Gbps (scalable)
Reliability: Extremely high (SLA-backed)
Availability: Available UK-wide but may require survey/installation
FAQs
1. What is the difference between FTTP and G-Fast?
FTTP provides full-fibre connectivity directly to your premises, offering faster and more reliable speeds. G-Fast uses existing copper infrastructure, which makes it quicker to install but offers lower speeds, especially for uploads.
2. Is a Leased Line worth the higher cost?
Yes, for businesses that require consistent high-speed internet with guaranteed performance. If your operations rely on real-time data, video conferencing, or large file transfers, a leased line provides the most reliable option.
3. How can I check what's available in my area?
You can contact BTT Comms for a free broadband audit. We'll assess your location and recommend the best connectivity options based on current infrastructure and your business needs.
4. How long does installation typically take?
FTTP and Leased Line installations can take a few weeks depending on local infrastructure. G-Fast is usually quicker to set up since it upgrades existing lines.
5. Can I upgrade later if my business grows?
Absolutely. Starting with G-Fast or FTTP is a good option for smaller teams, and you can scale up to a Leased Line as your data demands increase.

In 2025, both Openreach and CityFibre offer excellent fibre broadband options, but your decision may come down to location and your specific needs. For symmetrical speeds and newer infrastructure, CityFibre has the edge. For broader availability and more provider choice, Openreach remains a strong contender.
